Audiognome 160 is a step back for AudioGnome. While the few added features that people wanted were nice there was also some other features that were not wanted.
Version 160 is buggy and as you mention changed to many things. The release of 160 I feel was a bit rushed out
there were several issues that you mention being discussed by the testers prior to the release as well as many more.
1. You will not find a change log!
2. I currently suggest to back up profiles regularly as 160 seems to go corrupt more often than other versions.
3. Current suggested version by me is 145.
