Release notes
1.0.5
April 2026Fixes
- Fixed followed filters being auto-forked into your own private copy on app startup. The auto-fork now only triggers when you actually edit the filter, not when the file's timestamp changes for unrelated reasons (Steam Cloud, OS metadata, app upgrades).
1.0.4
April 2026 Initial ReleaseSync
- Two-way sync between your Last Epoch Filters folder and your muffin.gg account
- Drop a filter into your Filters folder and it shows up on muffin.gg automatically
- Save a filter on muffin.gg and it lands in your Filters folder ready to use
Followed filters
- Filters you follow on muffin.gg stay up to date in-game without you having to re-download
- If you tweak a followed filter locally, Filter Muffin makes you your own copy so the original keeps updating
Plays nice with the game
- Pauses while Last Epoch is running so it never touches a file the game is using
- Waits for Steam Cloud to settle after you close the game before resuming
- If a filter changed in both places at once, you get to pick which version wins
Tray app
- Lives quietly in your system tray with a status indicator
- Recent activity log shows what synced, when, and which filter
- Pause and resume sync from the tray menu any time
- Updates itself when a new version is released
First time installing?
Filter Muffin is code-signed, but Windows SmartScreen may still show a warning until the new installer builds up download reputation. If it does, click More info then Run anyway to continue.
