v0.18.5-Beta

#1369 #1306 Finally fix the "Windows must always have a parent" crashes

v0.18.4-Beta

#1306 Fix 0.18.0 regression. Logical data-race between window destruction logic and list-window might lead to a crash

I promised you a buggy release, remember? 🙂

v0.18.3-Beta

• #1306 Add more debug logging to catch the bug
• #1315 Fix regression. on-focus-changed/exec-on-workspace-change don't work if switch focus via 3rd party means (cmd-tab, dock)
• #1324 Fix regression. Revert window detection logic to 0.17.1 version. Don't treat some specific popups as windows
• #1305 Fix regression. Hotfix. Reduce wallpaper flickering (but a more proper fix is yet to be implemented)

v0.18.2-Beta

• #1292 Fix 0.18.0 regression. Windows of non-Dock applications couldn't be focused (touchID, "About This Mac", etc.)
• #1297 Fix 0.18.0 regression – random crash.

v0.18.1-Beta

Performance fixes:

• Make cmd-tab workspace switch as snappy as AeroSpace built-in commands
• Make mouse resize & move more responsive
• #218 Optimize focus switching logic. Now unresponsive apps don't affect focus switching at all

v0.18.0-Beta

This release primarily features performance improvements, the new icon and contributions from the community.

Previously, AeroSpace suffered from major performance problems caused by the fact that AeroSpace was a single-threaded application, and macOS accessibility API is a blocking API. If at least one application was unresponsive, it'd block the entire system. Starting from this release, AeroSpace implements thread-per-application model, which allows it to stay responsive even in the mentioned case. On top of that, the accessibility requests were made cancellable, which helps to avoid doing unnecessary work when consecutive accessibility requests could be coalesced.

AeroSpace is migrated to Swift 6 strict concurrency mode which hopefully will help to prevent data-races.

The performance problems are not fixed entirely, but the release lays down a good foundation for future fixes. In particular, Godot (and maybe some other apps) still introduces half a second delay for AeroSpace, but it doesn't entirely block the system anymore! (tracking issue for investigating Godot: #218) Another optimization direction is to entirely avoid accessibility requests to windows which are located on invisible workspaces (tracking issue: #545)

Thread-per-application is a significant shift in AeroSpace architecture, I expect quite a few bugs in this release. Please report bugs as usual, but I encourage you to check if the bug is introduced in 0.18.0.
