There's a new alpha release available for download. If you build Tor from source, you can download the source code for 0.3.3.2-alpha from the usual place on the website. Packages should be available over the coming weeks, with a new alpha Tor Browser release some time in February. Remember, this is an alpha release: you should only run this if you'd like to find and report more bugs than usual. Tor 0.3.3.2-alpha is the second alpha in the 0.3.3.x series.

It introduces a mechanism to handle the high loads that many relay operators have been reporting recently. It also fixes several bugs in older releases. If this new code proves reliable, we plan to backport it to older supported release series. Changes in version 0.3.3.2-alpha - 2018-02-10 • Major features (denial-of-service mitigation): • Give relays some defenses against the recent network overload. We start with three defenses (default parameters in parentheses).

First: if a single client address makes too many concurrent connections (>100), hang up on further connections. Second: if a single client address makes circuits too quickly (more than 3 per second, with an allowed burst of 90) while also having too many connections open (3), refuse new create cells for the next while (1-2 hours). Third: if a client asks to establish a rendezvous point to you directly, ignore the request. These defenses can be manually controlled by new torrc options, but relays will also take guidance from consensus parameters, so there's no need to configure anything manually. Implements ticket. • Major bugfixes (netflow padding): • Stop adding unneeded channel padding right after we finish flushing to a connection that has been trying to flush for many seconds. Instead, treat all partial or complete flushes as activity on the channel, which will defer the time until we need to add padding.

This fix should resolve confusing and scary log messages like 'Channel padding timeout scheduled 221453ms in the past.' Fixes bug; bugfix on 0.3.1.1-alpha.
