There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.4.3.1-alpha from the usual place on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release by mid-February.

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

This is the first alpha release in the 0.4.3.x series. It includes improved support for application integration of onion services, support for building in a client-only mode, and newly improved internal documentation (online at https://src-ref.docs.torproject.org/tor/). It also has numerous other small bugfixes and features, as well as improvements to our code's internal organization that should help us write better code in the future.

Changes in version 0.4.3.1-alpha - 2020-01-22

New system requirements: When building Tor, you now need to have Python 3 in order to run the integration tests. (Python 2 is officially unsupported upstream, as of 1 Jan 2020.) Closes ticket 32608.

Major features (build system): The relay code can now be disabled using the --disable-module-relay configure option. When this option is set, we also disable the dirauth module. Closes ticket 32123. When Tor is compiled --disable-module-relay, we also omit the code used to act as a directory cache. Closes ticket 32487.
