Sentry Crash Report:

Description João Figueiredo 2023-06-07 00:55:14 UTC 
SUMMARY
All undo history is lost after saving the project. This is very dangerous because it effectively means the history only lasts as long as the period between autosaves; if you accidentally delete something and it autosaves right after, it's lost forever.

STEPS TO REPRODUCE
1. Open a project
2. Change something
3. Save the project
4. Try to undo the change

OBSERVED RESULT
You can't undo it.

EXPECTED RESULT
You should be able to undo it. The undo history should persist in the same session between saves.
Maybe there could even be an option to save it within the project file itself, so it's always available across sessions.

Thank you for reporting this issue. We fixed it and the fix will be available in the next patch release of LabPlot 2.10 that we plan to do in the next weeks.
