The reported bugs from the previous RC release have been addressed. This release is still intended for testing with the English language. There is a known issue of abnormal behavior in Opera when hovering subnav menu items in the top menu; this will likely result in releasing a dedicated Opera theme for the manager shortly after the official 0.9.5 release.
Please continue reporting bugs in the exiting 095 RC support thread:
