StarOffice 8 Update 10 has finally been released as patch 120187-14 for Windows.
Contrary to previous patches, this one was quite troublesome to install: on both of my Windows machines (both with SO8 U9 already installed) the installation failed quit at the end with a failure to read the source .MSI file (claimed to be a network error, but that was just a crappy error message, all install sources were local). It then removed the whole U9 update, but StarOffice refused to load afterwards (incl reboot) because of missing DLLs and/or DLL entry points.
I had to repair SO8 base, then re-apply U10...
As I said, happened twice for me – cost me 2hrs each time ... so be careful.
