Below are the major changes of the released versions and links to more detailed release notes.
We are releasing today 0.4.7.6-rc which is the first release candidate of the 0.4.7.x series. One minor bugfix went in since the last alpha a couple weeks ago.
If no major bugs or problems are found, the next release will likely be the first stable. We are hopeful to get this out by the end of month of April at most.
We’ll be releasing a blog post for the first 0.4.7.x stable version to explain the massive changes that it will bring to the Tor network.
