- Custom themes can now define separate light and dark color overrides when automatic theme switching is enabled. (#837, thanks @aneym)
### Fixed
+- New lifecycle event subscriptions now stream only events emitted after subscription begins instead of replaying retained history. (#1270)
- Windows users whose endpoint security blocks the fileless PowerShell install command can now use a local `install.cmd` bootstrap; installer downloads use `curl.exe` while preserving package checksum verification. (#2751)
- Retained mouse selections now copy when Ctrl+C or Cmd+C arrives before a delayed mouse release instead of forwarding the copy shortcut to the pane. (#3100, thanks @moret)
- Removing a background worktree workspace no longer changes focus to its parent workspace. (#3098)
