New Release: Tor 0.4.2.5 (also 0.4.1.7, 0.4.0.6, and 0.3.5.9)

Ater months of work, we have a new stable release series! If you build Tor from source, you can download the source code for 0.4.2.5 on the website. Packages should be available within the next several weeks, with a new Tor Browser around January 7.

This is the first stable release in the 0.4.2.x series. This series improves reliability and stability, and includes several stability and correctness improvements for onion services. It also fixes many smaller bugs present in previous series.

Per our support policy, we will support the 0.4.2.x series for nine months, or until three months after the release of a stable 0.4.3.x: whichever is longer. If you need longer-term support, please stick with 0.3.5.x, which will we plan to support until Feb 2022.

Today we are also releasing updates to our older series: 0.4.1.7 (changelog), 0.4.0.6 (changelog), and 0.3.5.9 (changelog), which you can download at dist.torproject.org. Note that the 0.4.0.x series and the 0.2.9.x series will become unsupported early next year, so if you're running one of those versions, you should plan to upgrade.

Below are the changes in 0.4.2.5, since 0.4.1.4-rc. For a complete list of only the changes since 0.4.2.4-rc, see the ChangeLog file.

Changes in version 0.4.2.5 - 2019-12-09

Major features (directory authorities):
- Directory authorities now reject relays running all currently deprecated release series. The currently supported release series are: 0.2.9, 0.3.5, 0.4.0, 0.4.1, and 0.4.2. Closes ticket 31549.
Major features (onion service v3, denial of service):
- Add onion service introduction denial of service defenses. Intro points can now rate-limit client introduction requests, using parameters that can be sent by the service within the ESTABLISH_INTRO cell. If the cell extension for this is not used, the intro point will honor the consensus parameters. Closes ticket 30924.
