New Alpha Release: Tor 0.4.6.2-alpha
April 15, 2021
There’s a new alpha release available for download. If you build Tor from source, you can download the source code for 0.4.6.2-alpha from the download page on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release likely 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 0.4.6.2-alpha is the second alpha in its series. It fixes several small bugs in previous releases, and solves other issues that had enabled denial-of-service attacks and affected integration with other tools.
