Biggest news is probably various fixes for file names with non-ascii characters on Windows. (This has been fixed before, many years ago, but new problems have popped up since then.) On Linux and OSX this is not a problem since those platforms can use 8 bit characters for non-ascii filenames (utf-8).
Another similar problem fixed this time is for the included version of qjackctl in Windows, which didn't work if the path to the jack executable contained spaces. (This problem goes for all platforms though, but it's most likely only going to be a problem for the special version of qjackctl included with Radium on Windows, which doesn't require jack to be installed globally.)
Changes 5.9.9 -> 5.9.10:
- Sequencer: Fix graphics update when editing stretch or
speed automation. - Plugins: Fix creating undo when editing a native GUI.
- Sequencer: Draw seqblocks properly when seqtrack
height is smaller than font height. - Sequencer: Paint seqblock text and border in floating
point precision when they are moved (to avoid
jumpy text). - Audio file reader: Fixed code that perhaps could have
caused buggy behavior when trying to load a non-
existent file. - Crashreporter/Linux: Include desktop/window
manager info into the report. - Crashreporter: Include all environment variables
containing "qt" into the report. - Menus: Add "Test assertion reporter warning" and
"Test assertion reporter error" entries to the
Help -> Debugging menu. - Linux: Assert during startup that neither of
QT_QPA_PLATFORMTHEME, QT_QPA_PLATFORM, nor
QT_PLUGIN_PATH are set. - Linux:. Unset the QT_QPA_PLATFORM and QT_PLUGIN_PATH
environment variables in the startup script. Perhaps
this will fix some strange crashes reported by
anonymous users via the crashreporter. - Windows/crashreporter: Fix backtrace when program path
contains non-ascii characters. - Windows/sequencer: Fix editing seqblocks for audio
files containing non-ascii characters. - Windows/qjackctl: Fix starting the server when program
path contains spaces. - Windows: Fix loading audio files containing non-ascii
characters into the sequencer. - Windows: Fix problems with Ladspa and rdf when program
path contains spaces. - Ladspa: Updated included rdf file for calf. (Lots
of calf plugins are not placed in the uncategorized
category anymore.) - Sequencer: Remove gap between last seqtrack and
navigator.
