I'm not sure if these are already reported or fixed. For me, 1.5.0 is not release quality but I can work around the bugs.

In the 1.5.0 OSX dmg, the new table feature has these problems:
1. Changes made to tables are not recorded by undo.
2. If you make a new change to a table (then save it or not) and export to PDF, the new change is not in the PDF. You have to save, close, reopen scribus before doing PDF export.
