The "But it seems like new version has lots of problems" is a large over statement as there may be many who are experiencing problems, there are very more who have experienced no problems.
If this were a huge issue, then you really would see this forum light up.
Many of the issues (none that you mention or if you are experiencing any) have been resolved or partially resolved in the beta build that is currently running and the re-engineered files that some are testing outside of the beta program.
So things are moving along at what I would say is a reasonable pace, and the levels of posts have subsided.
