--2.4.28--

Added

• Parsing of command line arguments in executable mode for GOG, Amazon, Epic, EA Desktop, and Legendary (resolves issue 263). Previously these were being ignored. As far as I can tell UPlay, UWP, and Itch.io have no capability to pass command line arguments to executables.

--2.4.22--

Fixed

• Regression introduced in 2.4.20 resulting in ENOENT errors

Added

• SRM now remembers your sgdb artwork choices (caching sgdbId -> artworkId). It will remember these choices even if you delete your config/grids folder or if you change a game's app id.

• Artwork choices are stored in SRM's config directory under artworkCache.json. Moving this file to a new SRM install will instantly reproduce your artwork choices.

• Per parser option to backup SGDB artwork locally. Useful for parsers that experience frequent DRM takedowns.

• Artwork backups are stored in SRM's config directory under artworkBackups/. Moving this directory to a new SRM install will allow use of the backed up artwork.

--2.4.17--

Fixed

Added

Changed

• Subtle bug that prevented Remove All Added Entries from doing anything to categories or controllers when Preview hadn't been generated.

• Minor issue where image index wasn't being set to zero after an image was saved to steam (making it seem like the image didn't save even though it did).

• Graphical issue with scrollbar in EmuDeck theme

--2.4.14--

Fixed

• Filter out weird '0' userdata directories that were causing problems for people in 2.4.13. I don't have one, so I didn't catch this issue.

--2.4.13--

Added

• A global environment variable for the user accounts filter (planning to eventually make this parser field mandatory)

• A noice modal to set the global user accounts filter from settings.

Fixed

• Issue where shortcut passthrough wouldn't work on a directory containing only one shortcut.

--2.4.12--

Added

• Exceptions now appear in EmuDeck theme

Changed

• Use App Id instead of titles for import/export images (gets rid of title collisions and also issues with titles that have illegal filename characters)

• Total re-work of image downloading method to remove dependence on deprecated library request. Should also hopefully fix timeout issues, as it now automatically retries (once) if an image request times out.

Fixed

• A regression in 2.4.3 that would cause import to fail for other artwork types if a grid wasn't present.

--2.4.11---

Changed

• Some small quality of life UI fixes.

--2.4.10--

Added

• Show total number of batches in batch progress alerts.

Fixed

• Some small UI bugs that cropped up in 2.4.9.

--2.4.9--

Added

• Explanation of SRM's workflow on the preview page when no apps are present. Credit to @dragoonDorise.

• Highlight mandatory fields in create parser.

Changed

• Moved better-sqlite calls to a child process. This fixes crashes that have been happening since upgrading to Electron 24.

• Re-worked module windows-shortcuts-ps to use massively less RAM when doing shortcut-passthrough (only spawn one powershell process, per parse, not one per each shortcut).

• Increased api call timeouts.

--2.4.8--

Added

• Ability to comment things out in glob fields using \. 

• Config presets are now grabbed by version, so that older versions of SRM (from here on out) won't break when breaking changes are made to the presets files (they also won't receive any new presets, but c'est la vie).

Changed

• Made the whole parser clickable in the parsers list in the EmuDeck theme.

Fixed

• Exceptions ID not matching for steam parser

• CLI would hang on generate apps if no apps were found.

• Handling for bug in osName where an error would be thrown if powershell not found on a Windows system, issue 521

• Handling for issue where addedItemsV2.json could be invalid json. Also made the write synchronous so this is less likely to occur.

Removed

• Expandable set notation $()$ that could be used in the local images fields. Classic example of SRM being overcomplicated. I might bring it back if there is popular demand.

• Skip Accounts with Missing Data Dirs option (always true now)

• Use Account Credentials option (now set based on whether or not loginusers.vdf exists)

--2.4.7--

Fixed

• Fixed possibility of fix match creating duplicates or not working, state management changed to incorporate possibility of app id changes better.

Changed

• Optimizations for 1280x800 screen (Steam Deck). Should stop horizontal scroll bars from appearing.

• Improved consistency of fix match appearance with preview.

--2.4.6--

Added

• Ability to exclude titles from the preview! Exclusions are automatically saved as exceptions so that the user doesn't have to repeat them. If you want the title back, just go find the exception and get rid of it.

• Ability to set exceptions based on the exact app through an exception ID, e.g. if you have two titles with the same exact name they no longer need to have the same exceptions applied.

--2.4.5--

Added

• Ability to fix matches from the preview 🚀! Just click the little exclamation point on the left of the app (icon subject to change), select the game and boom match fixed. Best of all, SRM will automatically save your change as an exception so that you never have to change it again in the future.

• Exceptions are now searchable.

Changed

• Preview is now sorted in alphabetical order of title

--2.4.4--

Fixed

• Regression in 2.4.3: SRM was not remembering the artwork choices that were already in Steam.

--2.4.3--

Added

• New highly simplified EmuDeck theme (only recommended for EmuDeck users as it hides parser config).

• Everyone who has made a feature contribution is now in the about page.

• Legacy banner images now sym-linked instead of copied (reduces storage usage by 17%)

• Steam images become sources immediately after hitting save apps to steam. This means that if you have some (or many) SGDB requests time out you can just wait a few seconds and hit "save apps to steam" again and it will get only those images.

Changed

• Major re-factor of parsers service, parsers component, and preview component. Preparation for new and more powerful preview.

Fixed

• Glob and Glob Regex parsers with ** now follow sym-links once more (this was broken by the upgrade to glob 9.0, which no longer follows sym links by default).

--2.4.2--

Added

• Ability to add artwork for unofficial source mods via the steam parser

• Logging for when steamgriddb times out on an artwork request

Fixed

• Steam parser was broken in 2.4.1

--2.4.1--

Fixed

• Race condition bug in saving images to steam.

--2.4.0--

• Command line interface

• New default UI theme

• Batched Image downloading

Unfortunately on the Windows portable version the CLI can't print anything out (see electron-builder issue 3998), but the commands still work. I am tracking this issue and will update electron-builder as soon as it is fixed.

Solves the issue where SRM would hang on "Writing VDFs" when lots of images were being added. Batching is 500 images (100 games) at a time, with ten seconds in between in order to give SGDB's servers a break.

• Ability to filter by installed status and app type in steam parser (e.g. only get artwork for games, not tools).

• Windows Apps capability for UWP parser.

• Handling for DMCA'd images (SRM doesn't add the "This image has been taken down" fallback to steam)

• MSI Installer

• Helpful placeholders in parser fields.

Wiki

Changed

--2.3.51--

Fixed

• Hopefully fixed path undefined bug for UPlay parser

--2.3.50--

--2.3.37--

Added

• Ability to do shortcut passthrough for .desktop shortcuts on Linux.

Changed

--2.3.36--

Fixed

• Removed bluebird.

Fixed

• Logos got broken by a previous update that was using an outdated version of steam-categories. That is now fixed.
