Fix

Just updating the release notes as per the release management process step

Used chat-gpt provided wording for the following input:

Act like a mobile app marketer who wants to prepare a release notes for Google Play and App Store. I want to write effective app store release notes that help users understand the changes in our Simplenote mobile app. Prepare it based on this list. Do not write it point by point and keep it under 350 characters. It should be a unique paragraph:

- Better support for dark mode and edge-to-edge on Android 15
- Under the hood improvements
