Hi,
we are excited to announce the first stable version in the 4.5 series being ready for testing. It will be the next alpha as well. Bundles can be found on
https://people.torproject.org/~mikeperry/builds/4.5-build4/
Compared to 4.5a5 we were able to put another couple of important usability fixes into this release. We improved HTTP connection handling, the HTTP authentication experience and fixed the TLS connection display, to name a few. Moreover, we neutered Blob URIs to a great deal which can get used to track users across domains and, finally, brought all Tor Browser components up-to-date.
The complete changelog since 4.5a5 is:
