Thanks to Björn Kautler, Matthieu Casanova, Dale Anson, and Eric Le Lay
for contributing to this release.
Bug Fixes
- Support arm64 Java installations in the macOS launcher (#4123 - Björn Kautler)
- Do not forward the --verbose parameter in the macOS launcher to jEdit
during investigating startup problems (Björn Kautler)
- Show Temurin download link in macOS launcher if no compatible Java version
was found instead of java.com and oracle.com where Java 8 is promoted
(Björn Kautler)
- Support Java installations with paths that are not following the old naming
conventions regarding their version in the macOS launcher (Björn Kautler)
- Bundle the new MacOS 1.5 plugin instead of the old MacOSX 1.3 plugin
to become compatible with newer Java versions (Björn Kautler)
- Fix NullPointerException during saving autosave settings if no previous
autosave directory was set (Björn Kautler)
- BeanShell snippets and macros now work consistently and not suddenly change
behaviour anymore just because some BeanShell snippet defined a class.
This now disables reflective access to otherwise inaccessible fields through
simple syntax though, that used to work after a snippet with a class
definition was loaded. (#4118 - Björn Kautler)
- Fix the installation of plugins trying to use invalid file names
(Björn Kautler)
- VFSManager.canReadFile() was returning true only for directories
(#4102 - Matthieu Casanova)
- Allow user to choose filename when printing to pdf

- Key handling in the Errors dialog uses current keymap (#4128 - Eric Le Lay)
- Delete at the end of the line does not delete newline on java20, java21
(#4125 - Eric Le Lay)
- Freeze when deleting a directory and some children (race condition)
(#4132 - Eric Le Lay)
