macOS 12.0 or later is now required (due to Xcode 27 dropping support for deploying to older OS versions). CocoaPods support is also now dropped.
If you're not generating appcasts automatically, remember to add <sparkle:minimumSystemVersion>12.0</sparkle:minimumSystemVersion> element to <item>s in your appcast.
