Georg Koppen:
Hi,
we are happy to announce the first alpha in the 4.5 series. It contains a bunch of new things most notably the isolation of browser streams by URL bar domain, the obfs4 pluggable transport, a tor based on the 0.2.6 series, 64bit only OS X bundles, a first implementation of the security slider and a backport of the certificate pinning functionality. Furthermore, it includes updates, bugfixes and minor new features. The bundles can be found at:
https://people.torproject.org/~mikeperry/builds/4.5-alpha-1/
It seems the Windows bundles are missing here. I am currently uploading them to:

(thanks, Yawning, for this notice)
Georg
