Probably my request in not clear.
No no, it is entirely clear
All changes that were made are documented in the Subversion logs. We do not have any other place where we documented changes (and no, we're not going to search through the last 2 years of logs).
Major changes which cause a change in behaviour or features are marked with '
*', while minor changes that do not change behaviour are marked with '
-'.
About my request to replace the old binaries whith the new ones . Can I do this ?.
If you do it right, it will work just fine (I'm doing that every other week). However, if you do any such thing, you're out alone, no help from our side if your computer eats your cat and your house burns down.
When copying around stuff like that, it is easy mix up some old and new binaries/libraries/whatever, which may work or may crash, or it may seem to work for a while until you discover it doesn't. Thus, I cannot recommend doing so.
