v0.3.1

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

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

The Linux AppImage and portable program need glibc 2.38 or newer (Ubuntu 24.04, Debian 13, Fedora 39 or later); older systems use the Flatpak.
