Software Changelog

Release-by-release summaries of the anonymity tools our community follows, plus the operating systems people run them on. Routine point releases accumulate here as compact entries. Major events (security audits, architectural shifts, region-specific implications) get full posts in Updates.

Where to start

Most people need two pages: the Tor changelog, plus whichever one matches their device (iOS for iPhone, macOS for Mac, Windows for a PC, Android for an Android phone). The rest serve specific needs, such as running your own relay, switching transports when blocked, or doing censorship measurement.

Pages marked "with urgency ratings" use three-colour tags to answer how fast to act. The basis for those ratings is not identical across pages and is explained at the top of each one. Pages without tags track progress or features, and ask no update decision of you.

Most of our release translations begin life in zh-TW and reach English on a rolling basis, so these English pages carry fewer entries than the Chinese versions. Every entry links back to the upstream announcement.

Anonymity tools

Condensed release-by-release from upstream changelogs, keeping version numbers and issue references.

Operating systems

Your device is part of the attack surface. This group skips the line-by-line translation and answers "do you need to update now" instead. Android and GrapheneOS are the exceptions: upstream detail is unavailable for the former and the latter updates automatically, as each page explains.
