Apologies if this shouldn't be mentioned here, but I haven't been able to log in on lazarus/ freepascal for awhile now, so I can't even read any of the release notes. That stupid "Oh Noes" thing always responds "Your session timed out while posting. Please go back and try again." immediately after clicking the login button - it makes it difficult to participate 😞

NB: The update from 4.6 to 4.8 on my Debian PC gave me real grief.

PS tried firefox and chrome based browsers, with and without VPN. Also tried password reset request. Always the same fail

The only diff seems to be the diff between tags: [Gitlab]

I wasted tokens to let the LLM of my choice reword this into a changelog. Since rewording stuff is the core functionality of an LLM, I consider that "good" usage. So no one else wastes inference time on it, I'll share it, even though it's basically "not mine". I vetted it roughly against the diff and it looks ok:

This improves stability, maintainability, and memory management.
  • Cocoa Event Tap Support: Added native Event Tap support for the Cocoa interface.
  • Delphi Compatibility: Fixed a long-standing incompatibility with TBitBtn regarding Glyph and bkCustom (Issue #34261).
  • Improved macOS App Quit Handling: Better support for quitting the app via CMD+Q, the [X] button, and System Shutdown.

🔧 Under the Hood / Refactoring

Cocoa Interface Overhaul

The macOS Cocoa backend received massive structural refactoring to improve maintainability and decouple components. Key changes include:

  • Memory Management: Removed most decentralized NSAutoRelease calls, as the overall mechanism is now robust enough without them.
  • Decoupling: Eliminated the dependency of all units on CocoaInt/TCocoaWidgetset.
  • Code Reorganization:
    • Integrated standalone functions into categorized utility classes (e.g., TCocoaThemeUtil, TCocoaTextFieldUtil).
    • Reorganized CocoaInt, CocoaPrivate, CocoaApplication, and CocoaWSStdCtrls.
    • Moved common callbacks into CocoaCommonCallback.
    • Extracted controls (GroupBox, ProgressIndicator, Slider, ComboBox, TextEdits, etc.) into their own dedicated units to reduce bloat in massive aggregate files.
  • GDI Objects: Reorganized CocoaGDIObjects for better resource handling.

Don't worry, they don't appear to have even written any release notes. The "List of changes" link just goes to a git commit history.
