Mortar 0.3.15: Imports that bring every mod

Wed, 28 Oct 2026 00:00:00 GMT

New

Simplified Chinese is open for translation on Weblate, and joins the language picker once part of it is translated
Update in all profiles downloads a version you have not downloaded yet, then updates every profile that had the old one, and says which profiles it could not update
In the Flatpak, account keys go to your desktop's keyring when the Secret portal is missing, and Settings › Accounts warns when neither is there and keys are kept unencrypted
Add game shows each loader's own icon

Changed (9)

Paired computers must both run 0.3.15 to keep syncing configs and local archives: a computer now proves it holds the pairing key before Mortar sends it anything
The command line's backups trim, history trim, data cleanup and store remove need --yes; data cleanup --preview still lists without it
The Problems badge counts only the problems you need to fix
Startup timing for Risk of Rain 2 runs until the main menu is ready, and shows the loading after the title screen
A download that loses its connection tries again on its own before it fails, and a failed one says which site it could not reach
Replace with on a deprecated mod removes the old one once its replacement installs; one Undo brings both back
Merge offers Undo, and counts version changes as updates
On a narrow window, Home's buttons turn into icons
clamd scans trust only a clamd socket that root or the clamav user owns

Fixed (11)

Importing a Gale or r2modman profile no longer marks mods as no longer available when they ask for an old BepInExPack, depend on each other, or name BepInEx's pack another way; a mod whose dependency is gone imports without it and the profile's notes say so
Mortar sees Risk of Rain 2 running, so its in-game performance can be measured
Stardew Valley's per-profile game settings apply: Mortar reads and writes the file the game uses, and the window mode keeps the fullscreen settings in step
Test launch uses the launch options shown, and cancelling the dialog no longer saves them
The config text editor picks up a file the game rewrote, and asks before dropping unsaved edits when you switch mods
New badges on Nexus mods stay until you have looked at the mod
Two local archives with the same name each have their own favourite star
Endorse and Abstain show your choice when you reopen a mod
The Steam folders you added are searched when Mortar looks for Proton
A file over clamd's size limit is reported as too large instead of failing the scan
The New mod form's own fields are translated

Mortar 0.3.14: Make your own mods

Wed, 28 Oct 2026 00:00:00 GMT

New

Develop

A new Develop tab for making your own mods, with grid and list views and a filter
New mod is a step by step wizard: pick the kind of mod, name it, say what it does, choose a license and its dependencies, and Mortar makes the project from the game's template and its own development profile
New mod picks your GitHub account from the ones you are signed in to, checks the name is free, and warns when no installed .NET SDK fits the template
Suit and sound mods need no SDK: their project adds your files instead of building
New mod can start the development profile with the open profile's mods
Add an existing project folder or clone one from GitHub; a project you did not make runs nothing until you trust it
Each project card shows the mod's icon, version, build state, when it was last built, whether its files changed since, and its git branch and unpushed work
Build, or Build on save to rebuild as you edit; build errors read plainly
Test starts the game with your mod, one copy for client-only mods and two or more for multiplayer, laid out in a grid on screen, with the copies meeting in one game for Lethal Company
Test copies keep their own saves, so a test never writes your real game's saves
Start for debugging opens the game with its debugger listening
Release drafts what changed since the last version, then tags and publishes it, through GitHub when the project has one
Upload to Thunderstore packs and publishes a mod with your team's token, kept in the system keyring, and can upload the latest release again after an interrupted upload
Pack warns while a mod still carries the template's icon
Dependencies are required or optional, added from Browse or the wizard, and changed later in Edit details
Game code searches the game's code, shows any type as C# or IL side by side, finds where a method is used, and copies a hook for it
Open in editor opens a project in VS Code, VSCodium or Rider, whichever is installed
A card shows your mod's start-up time and frame cost from its last measured run, and Show log opens its own log in the Console
Remove from list can also move the project's folder to the trash, warning first about unpushed or uncommitted work
Mods you develop group under In development in Mods, and updates are not offered for them
The Updated column shows when a mod in development was last built

Mods

Disable asks about the mods that need the one you switch off and the libraries only it needed; Undo switches them all back
A switched off mod's config is set aside and comes back when you switch it on again; removing a mod sets its config aside too, so Undo or adding it again brings it back
A mod's update badge opens Update review on that mod
A mod's menu groups its version actions and its organising actions, with Update in all profiles beside Skip
Update review and the patch-day sweep warn about mods on the game's known-broken list
Extra mods folders install their mods into a profile you pick per folder, and again whenever the folder changes

Browse

Mods known to be broken are marked in Browse and import previews, with the reason and a mod to use instead, and adding one asks first
A known-broken mod's working replacement installs in its place and counts for mods that need the original
Preferred source can turn a source off for a game, so Browse leaves it out
Card stats are small icons, and a possible re-upload is a warning mark with its note in the tooltip

Play

Play can start SteamVR or the ALVR dashboard before the game, per game or per profile
The Sims 4's DirectX 9 build counts as the game running

Config

The config editor marks settings the host enforces or recommends through ConfigSync, and shows the host's value while you are in a game
Save host's values keeps the host's ConfigSync values as your own once the game closes

Console

Right-click a line to copy it or hide messages like it, from one object or from every object
Each game's known noisy messages are hidden by default, and you can show any of them again
The levels a game's Console opens with are ticked one by one
Copy takes the whole line with its method and object, and right-clicking a selection copies every selected message
Hidden messages are listed by where they come from, in a section of their own

Settings

A game's settings page switches between every profile's values and the open profile's own, showing each override beside the game's value
A setting another one makes moot is disabled and says what to change first

Saves

A save's missing mods line can be dismissed until the mods it wants change
A backup's Keep forever is its own pin button

Tray

Recent profiles sit under a Play submenu per game

Changed (12)

Built on Wails 3.0
Edit profile has tabs; a profile's overrides, loader options and startup options are edited on the game's settings page instead
Dialogs, menus and the sidebar are regrouped and tidied, and the sidebar fits a short window without scrolling
The Play menu's copies section is gone: Develop's Test starts linked copies, and Instances in a game's Play settings still starts several
Touch ripples are off unless you turn them on
Removing or switching off a mod takes its files out of the game at once instead of at the next launch
Many screens, menus and dialogs redraw far less, and History and notifications load older entries as you ask for them
What is new for a Mortar update shows formatted text
In-game performance measuring shows one clear state and live results
Notifications show the latest changes with All changes for the rest, and History draws the newest entries first
Config sits above Mods in the sidebar, every badge on the rail wears the accent colour, and a profile's notes render as Markdown
Load order items read Load earlier and Load later

Fixed (36)

A catalog fetched after Mortar starts reaches saves, Problems, the tray and the game list
Every Browse page shows each mod once and fills the screen
A custom download folder is safe: Mortar clears only its own finished downloads there, never your other files
Switching games or profiles quickly no longer shows the previous one's runs, reports, versions or profiles
Moving a folder to the trash works across drives
A failed catalog check never falls back to a cached catalog older than the one Mortar ships with
Nested mods sit beneath the mod that needs them even when it is in another group
Several copies of a game each keep their own log, so their errors count
On Linux a Steam game started directly, for several copies or a debug start, runs through Proton in Steam's prefix
Merging profiles carries Thunderstore packages, and a merge that fails takes back what it added
Cleanup never offers to remove a mod you develop, built or published, and no longer counts toward the Problems badge
Profiles added, renamed or deleted from the command line, a share or sync show in the window and the tray at once
A missing Thunderstore requirement links to its page and can be added in one click
Duplicates found after a run open the same chooser as Problems, and each copy names where it came from
Moving the data folder keeps profiles you moved to another folder
The backup before Play or an update holds the profile's own saves, never another profile's
Removing a mod keeps its settings for Undo, and a mod named BepInEx never takes the loader's own settings with it
A damaged Nexus cache file no longer stops Mortar from starting
FOMOD installers packed in a subfolder or naming files in another letter case install
Heroic's GOG games are found, and so are games and Steam libraries behind a symlink
Find the cause no longer blames a framework when one of its content packs crashes the game
All sources sorted by downloads or by updated no longer skips mods or shows empty pages
Play from a Steam shortcut no longer waits forever when the graphics question is due
Bug reports and diagnostics files write your home folder as ~
Command palette actions work from Settings and the other full pages
The Flatpak finds r2modman and Gale profiles in their usual folders
Find the cause asks before it starts relaunching a crashed game
Removing a custom game, unpairing a computer and restoring over saves ask first
A retried LAN transfer updates the profile you chose, and a sender that goes silent is retried
Edit profile keeps what you typed when a save is refused
Config cleanup spares a config an enabled mod still uses
Backups reuse the newest one while your saves have not changed
A SMAPI installer runs only when it matches the hash GitHub publishes
Imported settings, packs and shared profiles can no longer set programs, folders, launch prefixes or turn protection off, and shared changes carry text and data files only
Signed catalogs and lists cannot be rolled back to older ones, even after clearing the cache
Nearby sharing checks and limits what other computers send, and your Nexus key stays out of logs

Mortar 0.3.13: Live launches, dated versions

Sat, 24 Oct 2026 00:00:00 GMT

New

Play

The launch screen fills in as the launcher, the game and its loader come up, and stays until the mods have loaded
A slow launch says so with Keep waiting, gives up only after five minutes, and Cancel stops a launch at any step
A launch waiting on Steam can open Steam's window
For Stardew Valley the launch screen stays until the game's window opens, not just until SMAPI has found the mods

Mods

Change version lists each version with its release date, marks Latest and Installed, and names the version it installs
The details panel keeps a mod's version and what changes it in one section, and leads out through one column of links

Games

Add a game starts from the game's program, takes its name and how it is modded from the game's files, and says what each loader suits

Multiplayer and sharing

The Multiplayer mod list splits hosting from joining, and Fix all leads once a check finds something
An import can install a share as shared: at its versions and without the dependencies it left out
The Thunderstore modpack form groups its fields and folds the config list

Saves

A save's companion folders travel with it, so Cat Mail Co. backups carry CatLib's mod data

FOMOD

A plugin's always-install files, and its install-if-usable files while usable, install even when the plugin is not chosen

Changed (5)

Selecting, switching on and off and opening mods, Config, Settings, the Console, Storage and Load order all do far less redrawing and ask Mortar's backend fewer times
Dialogs share one look: no dividers, Close as a plain button, and lists that load behind placeholders in their own shape
Screenshots and Settings › Launchers show placeholders while they load, and a Settings search with no match says so in the middle of the page
Reduce motion also turns off the press ripple
Browse falls back from GitHub's API to its search page when the API refuses, and waits out a refused search instead of asking again for every topic

Fixed (29)

Mortar no longer freezes for a second or more each time a game starts, stops or changes state, which was worst right after Play
Every Browse page holds 20 mods after adult and hidden mods are dropped, the page count stays put between pages, and pages past the tenth fill
A Browse source that leaves mods out for excluded categories counts them as hidden; CurseForge sorted by thumbs-up neither repeats nor skips a mod
Signed out of Nexus, Browse and Settings › Accounts no longer raise an error toast
A site limiting Mortar's requests says so instead of "Something went wrong"
A launch cancelled while it prepares takes its files back out of the game; a cancelled launch ends as cancelled even when the game exits first
A game a system Wine runs is found by its path, and Steam, its wrappers or a system program are never taken for the game
A game whose log is late counts as started instead of as Steam failing to start it
GE-Proton10 ranks above GE-Proton9 when Mortar picks the best Proton
Load order follows SMAPI's own order, each mod's dependencies loading just before it
FOMOD files go where the installer says: a missing destination installs at the source's path and an empty one in the mod's folder
A MelonLoader setting spread over several lines, quoted category names and control characters read and save correctly instead of breaking the file
A config number a mod cannot read (1E5, Inf, 300 for a byte) is refused or rewritten so the game keeps it
A config search hit names its section, and a .cfg named after its package shows under that package
An INI section followed by a comment is found, so a setting is no longer added under a second copy of it
Cat Mail Co.'s saves are found
A Nexus file uploaded again under the same version counts as the newer one, and one mod id in two games no longer shows the other game's page
A Thunderstore dependency with no version or an extra dash is refused instead of misread
An ignored Thunderstore, CurseForge or Mod DB link is taken again when clicked again
Importing an r2modman or Gale profile keeps config files in BepInEx/config subfolders
A failed import removes the profile it made
A profile of a game Nexus does not host can be shared by link
An error after Pause or Cancel no longer marks a download Failed or Queued
With beta updates on, a refused prerelease lookup no longer hides a newer stable release
Keys saved while the Flatpak secret portal was missing are kept once it answers again
Recovery after a crash mid-restore no longer writes your file over the profile's copy, and a leftover link no longer blocks every purge
Many screens no longer show another profile's or game's answer when you switch quickly
A double click on Retry, Fix and similar actions sends once, and a failure's message offers Retry
Screen readers hear headings for each game, profile, save, launcher and first-run step

Mortar 0.3.12: Problems on one page, in your language

Thu, 22 Oct 2026 00:00:00 GMT

New

Languages

Mortar is open for translation on Hosted Weblate; Spanish (with Argentina and Panama variants) and Brazilian Portuguese are under way
Settings › General › Language lists a language once part of it is translated, with how much is done; following the system language switches only to a language that is mostly translated
The tray menu, desktop notifications, file dialogs and startup messages follow the language too
Help translate Mortar, beside the Language setting and in the guide, opens the project on Weblate

Linux

Graphics in Settings › Appearance: Smoother scrolling for computers where scrolling is slow or the fans spin up in Mortar, as on some graphics cards, and Compatible for a window that stays blank

Problems

Every section is on one page, each with its count; Slow startup, Redundant, Cleanup, Replaced and Dismissed are links under the list
Each problem has one button for its suggested fix, with the other fixes and Dismiss in its menu, and Why? beside it

Faster

Mortar starts with far less work drawing the Mods page
Switching a mod on or off rechecks problems sooner, Load order shows dependency names without waiting, and Settings › Storage sizes the data folder in about half the time
Searching every mod's settings on the Config page answers in a fraction of the time, most of all for BepInEx games
Selecting a mod, opening Settings, the Console and the title bar menus do far less redrawing, and a large profile's problem check after a switch takes a fraction of the time
The first problem check after Mortar starts takes about a quarter less time, game settings open without waiting on GitHub each time, the loader's state shows at once on start, and the Config tab's search filters once you pause typing

Wording

One word for each thing throughout: Enable and Disable everywhere, and "cannot" rather than "can't"
Error messages that said the same thing in different words now use one headline
Settings descriptions that only repeated their setting's name are gone

Play

Launch options… in the menu beside Play opens the profile's own launch arguments, command prefix and environment variables

Mods list

The list's columns follow each mod's own source and loader: Latest, Released, Updated, Rating and Downloads come from Nexus or Thunderstore, whichever the mod is from, and the id column shows a BepInEx plugin's GUID or a SMAPI mod's UniqueID under that name
A mod from GitHub shows its latest release, when its installed release came out and its downloads, once Mortar has checked it for updates
BepInEx games add Kind (plugin, patcher, library or files only) and Plugin version
The column menu is grouped: the mod, its versions, its health, its place in the profile, then its source

Browse

GitHub search finds mods under every topic their authors use: Lethal Company searches five topics instead of one (338 repositories instead of 122), Stardew Valley and Vintage Story three each
Searching for an author or organisation, such as LethalCompanyModding, lists their GitHub mods too

Fixed (26)

Skip the intro for Stardew Valley skips it: the Mortar SMAPI Bridge 0.2.9 that reads the setting now comes with every profile
A problem the Console shows for a run, such as a newer copy of a mod you are building loading in place of the installed one, has Dismiss; it stays dismissed in later runs until you choose Restore
The Console keeps your place while you read back through the log; new lines scroll it only when it is at the bottom, and dragging its scroll bar keeps up
A Nexus download of a BepInEx or MelonLoader mod that is only its DLL installs again; it was refused as an optional file of another mod
Add to group no longer shows "Something went wrong in this view" when the profile already has a group
Opening a mod's details in Browse keeps that mod on screen instead of jumping to another page
Browse's list view shows each mod's picture again; it had shrunk to a sliver under the star, which covered the name's first letter
Importing an r2modman profile brings a mod you added to it by hand as a local mod, instead of calling it removed from Nexus with a page link that does not exist
The What's new and sync dialogs close with Close
Adding a mod's zip that does not say who made it installs it, by Unknown as r2modman names it, instead of refusing it
A mod zipped inside its own folder, such as a suit pack with no DLL, installs as its package instead of asking for a mod folder
A mod added from a file shows its own icon.png when no site gives it a picture
A mod picture with a transparent background shows the card behind it on the Mods tab, as it does in Browse, instead of a coloured square
Animated mod pictures (GIF, animated PNG and WebP) play instead of stopping on their first frame
Creating a profile while Mortar is adding SMAPI's own mods to every profile no longer fails
A controller used in another game no longer controls Mortar in the background: pressing Start to pause that game used to start the open profile's game
The extra mods folder lists BepInEx and other Thunderstore games' mods, and a C# project's build folder as one mod, instead of asking each for a SMAPI UniqueID
A mod added from an extra mods folder is installed again whenever its folder changes, so a mod you are building stays current in the open profile
Importing a Vortex or Mod Organizer 2 profile for a game other than Stardew Valley names each mod from its own package or plugin instead of showing it blank
A BepInEx or MelonLoader game no longer offers Import from the game's Mods folder, shows new folders from it on the Mods tab or watches it, which only a Stardew Valley install has
The Cleanup list in Settings › Storage and the archive preview name BepInEx, MelonLoader and other Thunderstore mods, and group copies of one package, instead of showing them blank; the Downloads watcher names a Thunderstore zip by its package
An archive Mortar cannot install for a BepInEx, MelonLoader or other non-Stardew game is refused with words that say what Mortar expected, instead of "No SMAPI mod was found" or a question about a SMAPI manifest
A GitHub release installed for a BepInEx, MelonLoader or other non-Stardew game shows "Could not verify its source" in the queue, since there is no repository check for those games
A second Nexus file for a BepInEx, MelonLoader or other non-Stardew mod already in the profile installs as its own mod instead of asking to add it to the first
On Windows, a game that crashes stays "Running" until its process has fully closed, so its files are cleaned up and it no longer shows up as a second run of another profile
Stop game on Windows no longer fails with "Access is denied" for a game that is already closing, and a game Windows will not let Mortar end says so instead of offering Open storage settings

Mortar 0.3.11: Startups explained, errors traced

Thu, 22 Oct 2026 00:00:00 GMT

New

Linux and Windows

The AppImage runs on Linux Mint 21 and Ubuntu 22.04 (glibc 2.35 and newer)
The Flatpak keeps up with the other builds: switching a mod on or off takes a tenth of a second instead of a second, and the window opens sooner
On Windows the window opens straight away, without the long PowerShell pass some PCs saw before it
Use the system title bar, in Settings › Appearance, for desktops with their own window decorations

Importing and sharing

Gale profiles and r2modman or Gale codes bring the mods that were added from disk, as local mods, and the preview warns before a code's own program files install
In the import preview a mod's name opens its page, full names show and can be copied, and the whole tile shows what comes in

Mods and profiles

Local mods are marked in cards and the list (Mark local mods, on by default)
A selected card is tinted as well as outlined
The profile actions menu is grouped under headings and opens the profile folder
A mod's Needs and Used by include the libraries its plugins ask for

Performance and diagnostics

Performance opens on two cards, Startup and In game, with each phase named on the bar and the six slowest mods with their share of mod time
In game measuring starts on any launch, not only a measured one (Mortar BepInEx Bridge 0.3.2)
mortar.log times each step of Mortar's start, and Restart and record startup profile in the Mortar menu records the first 30 seconds for a bug report
Errors while running say which Harmony patch threw, on what, and at which source line
A crash names the native function the game died in, from Unity's and Microsoft's symbol servers

Games

Cities: Skylines II cities are listed and backed up per profile

Fixed (8)

After a Steam launch, Play now and Measure no longer stay greyed out once the game has closed
A library only a local mod's plugin asks for is no longer offered for removal
A game opened only for its setup page is no longer listed under Recently played
An error while running links to its own guide section
A program renamed with .old is refused in an imported profile, like any other program
The Flatpak on NVIDIA's proprietary driver gets the same rendering workaround as the other builds
Link previews of mortar.rethunk.tech no longer run words together
A card no longer shows a stray separator for a mod with no version

Mortar 0.3.10: Import anything, mod Cities: Skylines II

Tue, 20 Oct 2026 00:00:00 GMT

New

Importing and sharing

One Import dialog for every source: a link or code, a file, another mod manager, or the game's Mods folder, each ending in the same preview
Gale share codes import, in the short form and the older 22-character form
The import preview shows each mod's icon
Importing a file also reads Thunderstore modpack zips and local profile folders, and the file picker offers .r2z files and modpacks

Games and browsing

Paradox Mods for Cities: Skylines II: search, install, updates and requirements, with each profile's mods placed in the game's own Mods folder
Save folders for 46 more Unity games, so their saves list and back up
A page of Browse results fills the window
All sources sorted by downloads or by last update is one ranked list
A link to a mod opens the Mods list filtered to that mod

Crashes and memory

After a game crashes, its crash card also reads CatLib's crash report and opens its folder, and on Windows the Windows event log
When a game started directly crashes, the end of its output goes into the run's log, and a mod named in a .NET exception there is blamed on the crash card
Mortar's own process holds about a third of the memory at idle that it did, returning what start-up used once it goes quiet

Profiles and settings

A Size setting zooms the whole window, and the font list shows each font in its own face
Each game can sync its profiles to the Mortar-wide folder, to a folder of its own, or not at all
A game takes a list of extra mods folders instead of one
Open profile folder in the Profile menu
Home puts Saves beside Notes, with the changes since the last run below at full width
The browser extension reports updates from every site Mortar installs from

Changed (12)

Load order names missing dependencies in seconds instead of half a minute on a first visit
Starting Mortar does less work: Content Patcher checks survive a moved data folder, overlay images are not decoded again, the weekly profile check waits until Mortar is idle, and the backdrop is resized once
Thunderstore answers from the stored listing at once and refreshes it in the background, and Problems and Browse no longer decode the whole listing
The tracked Nexus mods card shows at once from the last list and refreshes behind it
The Launch menu on Home is called Tools, so it no longer reads as starting the game
Share and Import close with their own X and have no Cancel or Close beside it, each Share destination is as tall as what it shows, and Last used sits in a tile's corner
An import shows a progress bar while a link, code or file is read, and a link or code that cannot be read says what was wrong with it
The mod list offers its Thunderstore format only for games modded from Thunderstore
Problems shows the last SMAPI answer at once and asks smapi.io again in the background, and an empty tab says what it is checking
Opening Game Select runs no Problems or Updates checks, and Storage measures disk use only once its section is on screen
The category pickers say why categories could not load instead of that the site has none
The integrity check shows its outcome as a green, warning or red result

Fixed (18)

Mortar reopens maximised when it was closed maximised, at the right size instead of past the screen's edges
Buttons, lists and menus use the font chosen in Appearance, and a config's Sections list is wide enough for its names
When some update checks do not answer in time, a notice says so with Check again and Dismiss, and a slow smapi.io batch is asked again before its mods are left unknown
BepInEx mods keep their manifest.json, icon.png and readme, so in-game mod menus such as Cat Mail Co.'s can read them, and no stray .complete file is added
Thunderstore packages whose names differ only in case no longer replace each other, and the live package wins over a deprecated twin
An import skips packages the Thunderstore index cannot resolve instead of failing
A game without a save folder has no Saves page, no Saves card on Home, no Save backups page, and no warning before Play
Report to author opens the GitHub issue with as much of the report as fits in its link, and says to paste the rest
Open log on an error opens Mortar's own log, and only a failed game launch opens the game's
Opening a profile of another game, from an import or elsewhere, switches the game in the title bar to match
Windows Task Manager lists Mortar by name instead of by a description
Category chips show their full names, the caret sits right after them, and Enter picks the first match
A search handed from Mortar's settings to a game's settings no longer says nothing matches
Accent cards no longer show a radio button, the background preview draws on Linux, and text over game art keeps a dark edge
Settings pages end with a gap, and launchers sit in two columns
Before you play names a disabled requirement by the copy you have installed
Two sites that share a driver no longer show each other's top mods
The command line labels only mods in the Tray folder as (Tray)

Move from r2modman, Gale or Vortex

Tue, 20 Oct 2026 00:00:00 GMT

Mortar reads the profiles other managers made, previews them, and leaves the originals as they were.

Share a profile as a link

Tue, 20 Oct 2026 00:00:00 GMT

Send a whole profile to a friend as one link or a .mortar file, and get everyone on the same mods before you join.

Play from Steam Deck Game Mode

Tue, 20 Oct 2026 00:00:00 GMT

Set Mortar up once in Desktop Mode, then start each profile from Game Mode like any other game.

Mortar 0.3.9: Errors explained, builds auto-install

Mon, 19 Oct 2026 00:00:00 GMT

New

Problems and diagnostics

An error a mod hit while running names the method it was thrown in and the other mods that patch code on that path
Errors from a run that went on are listed once under Errors while running, apart from mods that failed to load, and are not counted as problems
A File conflicts tab naming the files one package wins from another, with Make … win
A mod whose manifest is missing or broken shows as Damaged, with Repair
A warning when a mod's path is too long for a Windows game
The files a sync replaced, with Restore and Delete all
Last run rows, deprecated mods and compatibility-list rows can be dismissed
The console shows an error repeated over and over once, with a ×N count

Mods and browsing

One card for a mod its author lists on several sites, with re-uploads marked
A folder set to Auto-install puts its contents into the open profile each time they change, for a mod's build output
The first download from GitHub or itch.io says once that nobody moderates the site, and so does importing a profile with such mods
Make a group, or Add to group, brings along the mods the chosen ones need
Implicit mods nest under the mod that needs them, folded into a +N libraries chip on cards
Category pickers show +N for chips that do not fit, and noisy categories start excluded
Each game keeps its own include, exclude and sort; Browse sorts by most downloaded by default
A long config file lists its sections down the right, and an option centres each setting's control

Games

43 more Thunderstore games on loaders Mortar drives
A game no store tracks takes the folder you choose; Voices of the Void on Shimloader
Game Select sections fold away, and Hide this game moves to the row's right-click menu
The game switcher shows each game's art, profile count and when it was last played

Profiles and launching

The Play menu holds Instances and Delay, with Launch all copies; on a store launch it offers Direct launch
New profile can start from a saved group
Restore from a file sits beside Back up in the profile menu
Saves open as cards
Favourite stars and source marks sit on each mod's picture

Changed (2)

Stacklands, Core Keeper and Wrestling Empire leave the catalog: their Thunderstore pages send modders to the Steam Workshop or mod.io
Game Select rows keep one height; the hover grow and its setting are gone

Fixed (12)

Add to group from a mod's menu opens its dialog and takes every selected mod
Use Direct launch in the Play menu takes effect at once
A save only stops a launch for the mods it names, and Play anyway stops asking about them
Before you play counts missing mods once and fits its actions on one row
Lethal Company plugins that loaded and then logged errors are no longer reported as failing to load
The crash search keeps a library on while a mod that needs it is on, and first checks the crash happens at all
Importing profiles from other managers opens the game on the first one, and does not import the same profile twice
Opening a config file while another mod's config still loads no longer leaves the pane empty
The Mods and Config tabs do much less work when you switch a mod or pick a file

24 Nexus Mods games whose mods go in a folder the game reads itself: The Witcher 3, Cyberpunk 2077, 7 Days to Die, Blade & Sorcery, Monster Hunter: World, both Kingdom Come games, Hogwarts Legacy, Stellar Blade, S.T.A.L.K.E.R. 2 and more

Full changelog

Mortar 0.3.4: 136 more Thunderstore games

Sat, 17 Oct 2026 00:00:00 GMT

New

Games

136 more Thunderstore games: 104 on BepInEx 5, and 32 Unity IL2CPP games (Cat Mail Co. among them) on the shared BepInEx 6 pack
BepInEx 6 IL2CPP games get the game's Unity base libraries with the loader, so the first start needs no network
Each game, or each profile, can choose which of Steam's Proton builds runs its Windows copy outside Steam
Game select's group headings count their games

Mods and browsing

Mortar records whether you asked for each mod or it came in for another one (Explicit or Implicit): group, sort and filter by it, mark a mod either way, and show implicit mods in place, nested under the mods that need them, or hidden
A profile made before this offers once to mark its libraries, frameworks and tilesheet packs implicit, and Review… lists why each was picked
Removing or switching off mods offers to remove or switch off the libraries only they needed
Saved groups replace bundles: save a group to your library and add it to any profile
A BepInEx mod's other text files (YAML, TOML, XML, INI, JSON and TXT) open in the Config page for editing
A tidier details sidebar, and the group header at the top stays in view while the list scrolls

Profiles and sharing

A share can leave out libraries and supporting mods and name only the mods you chose; links and .mortar files carry each mod's install reason, pin and groups
The import preview shows the mods a share marks as dependencies
A profile row counts the mods you chose beside the total
A screenshot can become the profile's cover

Problems and diagnostics

Cleanup lists dependencies no switched-on mod needs any more
A mod that needs a newer game version than you have shows as Broken, Vintage Story's included

Downloads and updates

A simpler update review: one Update button per mod, library updates last under Libraries, and a one-row footer
When smapi.io stops answering, the offline banner says so, and it clears when smapi.io answers again

Fixed (13)

Mods and browsing

Large profiles are much quicker: switching a mod, filtering, opening the list or grid, Browse search and Settings search redraw a fraction of what they did
Switching, pinning or noting a mod keeps its details open and your selection
The details panel follows the selected mod again
Updating or rolling back a mod keeps it in its groups

Problems and diagnostics

Cleanup no longer offers to remove a mod a switched-on mod needs, whether its manifest, its Nexus page, a content condition or the images it changes say so

Profiles and sharing

A .mortar file carries the profile's groups whether or not it carries notes, and restoring a zip backup restores them

Launching and loaders

Mods for an IL2CPP game get the BepInEx 6 the catalog names, not BepInEx 5
Bridge features are offered only for games Mortar has a bridge for
On Linux, whether WebKit's DMA-BUF renderer is turned off now follows the installed graphics drivers, not PRIME offload
Game select no longer reloads every game's run history in a loop

Interface and settings

No more message codes in place of text, such as the one that stood in for "4 updates ready"
Every popover is solid, the Saves backups menu included
The Mods page callouts match the update bar's height

Mortar 0.3.3: Vintage Story

Fri, 16 Oct 2026 00:00:00 GMT

New

Games

Vintage Story: Mortar finds the copy its installer or Flatpak put in place, browses and installs mods from the Vintage Story Mod DB (and Nexus and GitHub), names each mod from its modinfo.json, fetches the mods each one requires, and turns them on for the length of each launch
The Mod DB's 1-click install button can open in Mortar: turn on Handle Vintage Story Mod DB links in Settings › Downloads
Each Vintage Story profile keeps its own mod settings (ModConfig), and the Config page edits them
A game no store has art for shows art from its own install
On Linux, a Windows game outside Steam, such as a copy in a folder you chose or one Heroic or Lutris installed, runs through a Proton version your Steam already has, in a prefix Mortar keeps for it
Settings › Launchers lists launchers that only run on Windows, and a row for games found where their own installer or Flatpak put them

Saves

Vintage Story worlds show their name, play style, play time and the game version that last saved them
A Vintage Story world lists the mods it was played with that the profile lacks, and installs each from the Mod DB
The world backups Vintage Story makes itself (Modify World and /genbackup) are listed under each world and restore like Mortar's own
A Vintage Story world's minimap is backed up and restored with it

Interface and settings

A Screenshots tab shows the game's own screenshots and, for a Steam game, the ones Steam takes, newest first, full size on a click
Browse cards put Add under the mod's picture, so the name, author, summary and stats get the card's width and read apart

Profiles and sharing

Vintage Story Mod DB mods travel in share links, sends to your other computers and the share page

Launching and loaders

The Console shows Vintage Story's own log while it runs, and a run that crashes keeps the game's crash report

Fixed (9)

Saves

Restoring a save no longer leaves the current save's leftover files beside it, which could undo a Vintage Story restore
Saves lists every game's saves without the internet; only Stardew Valley's mod matching needs it

Launching and loaders

Mortar finds your Steam account on current Steam clients, so Steam launch options, shortcuts and screenshots work again
mortar.log keeps the startup lines that are the only trace of a WebView2 failure

Interface and settings

On Linux laptops with an NVIDIA graphics card beside an AMD or Intel one, Mortar no longer renders at a crawl: it keeps WebKit's fast renderer unless it is running on the NVIDIA card
Menu items no longer say "Stop the game to change mods." when no game is running
Performance's Where the time goes is one stacked bar again, with each phase's time beside its colour
Buttons beside a text field are as tall as the field
The Nexus key and the browser extension steps sit in their setting rows

Mortar 0.3.2: Animated backgrounds, Epic games

Fri, 16 Oct 2026 00:00:00 GMT

New

Interface and settings

Animated backgrounds: an animated GIF, WebP or PNG plays behind Mortar, and holds still when Reduce motion is on or while a game is running
Settings › Appearance says when a background image is large enough to cost memory and GPU, and suggests WebP
What's new groups each release's changes by area, with a New or Fixed label on every line, and after an update that skipped versions it also shows each release you missed
Bottles shows its own icon in Settings › Launchers

Saves

A save's backups also list the copies the game keeps itself, Valheim's automatic world backups and The Sims 4's rollback copies, and restore them like Mortar's own

Games

Games installed through the Epic Games Launcher on Windows are found, and Play starts them through the launcher: Risk of Rain 2, Enter the Gungeon, Outward and Totally Accurate Battle Simulator
On Linux, Mortar also lists those games when Heroic installed them from Epic
Games installed through the Xbox app on Windows are found: Valheim, Inscryption and Bomb Rush Cyberfunk
Setting up a game that no launcher found offers any copy Mortar finds in your Desktop, Downloads or Games folders before you pick a folder yourself

Problems and diagnostics

A bug report names the build beside the version, and mortar.log starts with the version, build and platform

Mods and browsing

Browse cards can show downloads, endorsements, likes or stars, file size, version and last updated under the summary: tick the ones you want under Show › Card details
Card details show file size for Nexus Mods and Modrinth mods too, as for Thunderstore and CurseForge
The Mods tab's cards show the same Card details: endorsements, downloads, size on disk and last updated

Fixed (18)

Games

Creating a Lethal Company or Valheim profile no longer fails with "does not say who published it"
Newer Steam games, such as Super Battle Golf, show their art in Game select and the game menu
The Sims 4 played in German, French, Spanish or Dutch finds its Mods, saves and Options.ini, which the game keeps in a folder named in that language

Launching and loaders

A catalog update holding a game this version cannot read no longer sends Mortar back to its built-in catalog; it leaves out only that game
When Mortar cannot start, it says why in a message instead of closing without a word, with a button that opens the folder holding its log; on Linux without zenity or kdialog the message arrives as a desktop notification
Starting Mortar while it is already open brings its window back even when the page inside had stopped responding
A Mortar that has frozen no longer swallows the next start: that start offers to end it and open a fresh one
Windows: the installer installs the WebView2 Runtime when it is missing or was removed, says so if that fails, and Mortar asks before starting without it

Downloads and updates

What's new no longer shows an error when GitHub cannot serve a release's notes; it waits for the next update instead

Mods and browsing

Browse and imports leave out Mortar's own bridges, which Mortar installs itself, so a profile can no longer load a second copy

Saves

Lethal Company's Saves lists each slot once: the backup and temporary files the game writes beside a slot belong to it, and each save says whether it is a save slot, an extra slot added by a mod, or the weekly challenge
Saves leaves out the Season and Fits columns for games whose saves record neither, such as Lethal Company

Interface and settings

Menus are wide enough for their longest item, so Check mods and Mortar for updates is no longer cut off
A menu item still cut off at the menu's widest, such as a long profile name, shows its full text on hover
Game select's letter rail spreads down the whole window, with letters that grow with it
Game select lists the games found on this computer right after the ones you played recently, ahead of the rest of the catalog, and the game menu in the title bar lists only those, with All games for the rest
Saves no longer scrolls sideways in the list view
An error message names what went wrong instead of "Something went wrong"

Mortar 0.3.1: 46 more games, and The Sims 4

Thu, 15 Oct 2026 00:00:00 GMT

New

Games

46 more games modded through BepInEx and Thunderstore, among them R.E.P.O., Risk of Rain 2, PEAK, Content Warning, Inscryption, Cult of the Lamb, Sun Haven and Enter the Gungeon; 14 of them also browse Nexus Mods
The Sims 4: each profile has its own Mods, saves and game options, Tray files go to the game's library, and mods come from CurseForge, Nexus Mods, GitHub, Patreon posts and itch.io pages
Games installed through the EA App are found and started
The Sims 4: Import from the game's Mods folder reads the mods already in Documents › Electronic Arts › The Sims 4 › Mods, at first set-up and from the Import menu, switched-off files included, and can move them out of that folder

Mods and browsing

Paste a Patreon post or an itch.io page in Add mod: it opens in your browser, and the file you save from it is offered and recorded under that page
Review the mods in the game's own Mods folder against a profile and bring them in
Typing in the mod list jumps to a mod the way Game select does: punctuation is ignored and digits count
Find on Nexus: mods imported from another manager or a folder with no page get their Nexus page and file back, from the Source grouping of the Mods list; Set Nexus page… in a mod's menu names the page by hand
CurseForge's Install button can open Mortar: turn on Handle CurseForge links in Settings › Downloads; links for games Mortar does not manage go back to the CurseForge app

Profiles and sharing

Merge one profile into another, as one step you can undo
Scheduled save backups, the run log, the console, conflicts and requirements can be set per profile
A profile can keep its own copy of the game's options file
Share › Mod list saves the list to a text file, and Multiplayer mod list loads a host's list from one

Launching and loaders

Play asks which graphics API to use for games that offer more than one, and asks again after a start that fails under another
The game's caches are cleared on the first start after a profile's mods change

Problems and diagnostics

Problems lists game settings your mods need switched on, and a Redundant finding can be dismissed and restored

Interface and settings

Game select is one alphabetical list with your recently played games on top, a letter rail to jump with, and typing a name finds it
The Windows installer offers to open Nexus and Thunderstore links with Mortar, and Mortar offers to take them back when another app claims them
Settings › About shows the build, and Open log folder finds the log
Join our Discord from the app menu, the Welcome screen and the site

Fixed (21)

Launching and loaders

Windows: SMAPI starts when Steam's launch options do not name it, a hidden SMAPI no longer hides the game window, Stop ends the whole game, and no console windows flash when Settings opens
A game set up from a folder you chose, or found through another launcher, starts directly instead of being handed to Steam, and on Linux a Windows-only game outside Steam or Bottles says why it cannot start

Mods and browsing

A Thunderstore update is found by the package's id, so a namesake cannot hide it, and other mod managers are left out of search and installs
The stored Thunderstore listing takes about a quarter of the disk space, loads twice as fast, and leaves memory after ten idle minutes
A space typed inside a mod's name no longer switches the focused mod off
A config file no mod owns opens alone instead of beside a second list
An itch.io key is accepted
A mod whose page is not known shows Unknown source instead of Nexus Mods
Installing an archive over a mod from a site keeps its page, picture and update checks instead of turning it into a plain Archive

Profiles and sharing

Windows: LAN sharing never listens on a network set to Public, and its firewall rules cover every network type so Windows does not prompt
Importing from Vortex reads mods it deployed as links
Multiplayer mod list: Check reads the text Share › Mod list makes, in all three formats
Share › Mod list names a mod once when several parts of one download share its name and version
Edit profile no longer scrolls sideways, and a long game list no longer widens the page

Downloads and updates

A second Install waits for the running download instead of failing
Changing mods no longer puts off the update check
A crafted archive or image can no longer make Mortar run out of memory
Review updates lists an update from another site that Mortar cannot download itself, instead of counting it and showing nothing
A CurseForge Install link for a mod whose author only allows downloads from its page is refused by name with what to do, instead of failing in the queue

Interface and settings

Closing the window quits when Mortar is not kept in the tray, and the tray's Quit works with the window closed
Tooltips, the reasons a control is off and an update's requirement changes are reachable by keyboard, and the sidebar is one tab stop walked with the arrow keys

Mortar 0.3.0: Lethal Company and Valheim

Wed, 07 Oct 2026 00:00:00 GMT

New

Lethal Company and Valheim: Mortar finds them, installs BepInEx, and installs mods with all their dependencies. Valheim runs natively on Linux with no Proton needed
Thunderstore is a mod source for Lethal Company and Valheim, and CurseForge is a mod source for Stardew Valley
Browse searches every source at once, shows one card per mod, and lets you pick the source by its logo; an empty search lists each source's top mods
A details panel for every mod: description, versions, dependencies and changelog, with filters by category and sort
Load order and Performance tabs for Lethal Company and Valheim: the order plugins load, how long each takes at startup, and frame times and each plugin's cost while you play
While the game runs, each mod shows whether it actually loaded, and Mortar records the game version you played
Skip the intro is a per-game setting
Problems catches much more before you press Play: missing or incompatible plugins, dependency loops, two mods shipping the same plugin, deprecated packages with their replacement, and mods that change the same game code
Crash help names the likely cause of a crash, can find the mod behind it by testing halves of your list, and shares the log with one click
Import profiles from r2modman, Gale, Vortex and Mod Organizer 2, and share as an r2modman code or a Thunderstore modpack
Back up a whole profile to one file, including its saves and mods no site can download again, and restore it as a new profile
Pair two computers with a code to send profiles over your local network, or keep them in step through a sync folder
One Updates list across all sources, with Update all, a restore point and Undo all
A config editor for mods' settings files and their in-game settings menus
Steam Deck: play with the gamepad, larger touch targets, and start games in Game Mode
Mortar finds games installed in Bottles and launches them through it
The browser extension is on the Chrome Web Store for Chrome, Edge and other Chromium browsers
Settings has Accounts and Source health pages, a per-game source order, and a search that understands common words

Fixed (11)

The mod list, details panel, profile checks and startup are much faster
Downloads are checked against the site's hash, and a damaged one is dropped so Retry fetches it again
Saves are backed up before every update
Only real crashes are reported as crashes, and Stop asks the game to close before ending it
SMAPI no longer refuses to start after an earlier crash
Errors explain what went wrong instead of saying "Something went wrong"
Add to Steam updates its shortcut instead of adding a second one
A damaged mod archive fails that one install instead of closing Mortar
An update never replaces an unrelated mod that came from the same page
Undo covers config edits and keeps a mod's settings when you roll it back
Menus and tooltips are solid, lists no longer flash on first draw, and keyboard shortcuts no longer take over Enter, Space and the arrow keys
