26. January 2023
- Infra & Releases
- Fixed issues with Windows signing

- General
- Hackathon in TQtC
- The WebAssembly PySide Team was almost doubled in size (+1 brain, +1 hand)
- Infra & Releases
- Windows signing to be improved.
- LTS releases into oss repo: some issues appeared but will be merged soon.
- Bugs & Features
- PYSIDE-1994: De-virtualization of Shiboken embedded Python files is now an option controlled dynamically by SBK_EMBED
- PYSIDE-1019: A dormant __feature__ initialization timing problem was fixed while implementing de-virtualization
- PYSIDE-1735: De-coupling of old and new enums was started
- PYSIDE-1564: Debugging of multiple inheritance continues
- Fixed some bluetooth functions in PySide6.
- Low Energy Scanner Example
- PYSIDE-2194: Progressing with this. Definitely a thread issue which allow-thread doesn't seem to fix.
- Possible solution for problems with PySide6 inside conda (compat package with qt6.conf file), but investigating if best solution
- PYSIDE-1994: De-virtualization of Shiboken embedded Python files is now an option controlled dynamically by SBK_EMBED
