New alpha release: Tor 0.4.1.2-alpha

There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.4.1.2-alpha from the usual place on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release by some time next week.

Remember, this is an alpha release: you should only run this if you'd like to find and report more bugs than usual.

Tor 0.4.1.2-alpha resolves numerous bugs--some of them from the previous alpha, and some much older. It also contains minor testing improvements, and an improvement to the security of our authenticated SENDME implementation.

Changes in version 0.4.1.2-alpha - 2019-06-06

Major bugfixes (bridges):
- Consider our directory information to have changed when our list of bridges changes. Previously, Tor would not re-compute the status of its directory information when bridges changed, and therefore would not realize that it was no longer able to build circuits. Fixes part of bug 29875.
- Do not count previously configured working bridges towards our total of working bridges. Previously, when Tor's list of bridges changed, it would think that the old bridges were still usable, and delay fetching router descriptors for the new ones. Fixes part of bug 29875; bugfix on 0.3.0.1-alpha.
Major bugfixes (flow control, SENDME):
- Decrement the stream-level package window after packaging a cell. Previously, it was done inside a log_debug() call, meaning that if debug logs were not enabled, the decrement would never happen, and thus the window would be out of sync with the other end point. Fixes bug 30628; bugfix on 0.4.1.1-alpha.
