macOS 27 Preview 5 (experimental)

Experimental build for macOS 27 (Golden Gate) — not on the Sparkle update channel.

Out of update channel — install manually; Sparkle / appcast.xml were not updated.

Active development preview. Issues with Focus and multiple items from the same app should be improved versus earlier builds. Items from the same app still cannot be separated independently.
