We have new stable releases today. If you build Tor from source, you can download the source code for 0.4.3.6 on the website. Packages should be available within the next several weeks, with a new Tor Browser by the end of the month.
There are also updated versions for older supported series. You can download 0.3.5.11 and 0.4.2.8 at https://dist.torproject.org/.
These releases fix TROVE-2020-001, a medium-severity denial of service vulnerability affecting all versions of Tor when compiled with the NSS encryption library. (This is not the default configuration.) Using this vulnerability, an attacker could cause an affected Tor instance to crash remotely. This issue is also tracked as CVE-2020- 15572. Anybody running a version of Tor built with the NSS library should upgrade to 0.3.5.11, 0.4.2.8, 0.4.3.6, or 0.4.4.2-alpha or later. (If you are running a version of Tor built with OpenSSL, this bug does not affect your installation.)
Tor 0.4.3.6 backports several bugfixes from later releases, including some affecting usability. Below are the changes in 0.4.3.6. You can also read the changes in 0.3.5.11 and the changes in 0.4.2.8.
There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.4.4.2-alpha from the download page on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release around the end of the month.
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 second alpha release in the 0.4.4.x series. It fixes a few bugs in the previous release, and solves a few usability, compatibility, and portability issues.

Starting today, July 8th, the Tor Project is running a one month campaign called #MoreOnionsPorfavor to raise awareness about onion sites, that is, websites available over onion services. We recently released a feature called Onion-Location in Tor Browser that announces to users if a website has an onion site available. Join us to make a more secure web! To participate, enable Onion-Location, share your onion site using the hashtag #MoreOnionsPorFavor on your favorite social media, and we'll select some onion service operators to receive a Tor swag. See below for all the details.
