9.0.40 SR4

Breaking Changes

• Fix Android TextView being truncated under some conditions by @albyrock87 in #27179
  • We want to highlight a minor layout change: due to fixing some rounding errors, certain controls may now display with an additional pixel of space, though this is unlikely to cause breaking changes in your applications. In our testing process, we had to regenerate all reference images, but the visual differences are minimal (typically just a single pixel variance), which you can verify by reviewing the PR where the old and new images appear virtually identical.
• Improve shadow rendering on Android, fix shadow clipping on iOS
  • Prior to this PR, negative shadow offsets were not rendering correctly. If your app uses negative offsets for shadows, you may notice visual changes in how shadows are displayed after updating. Your shadows will now render as originally intended with the correct offset positioning.
• Revert CollectionView, the footer moves to the bottom of the page when the empty view or empty view template is enabled
  • This reverts a breaking change in 9.0.30 where EmptyView no longer occupied the entire screen

Highlights

• Implement Mac TitleBar by @tj-devel709 in #25670

• Improve shadow rendering on Android, fix shadow clipping on iOS
  • It's recommended to use solid backgrounds along with shadows on Android to enhance rendering performance.
