+Changes in version 0.4.6.8 - 2021-10-26
+ This version fixes several bugs from earlier versions of Tor. Worth
+ noting is a fix on how we use DNS timeout to report general overload.
+ Everyone running an earlier version, whether as a client, a relay, or
+ an onion service, should upgrade to Tor 0.3.5.17, 0.4.5.11,
+ or 0.4.6.8.
+
+ o Major bugfixes (relay, overload state):
+ - Report the general overload state for DNS timeout errors only if
+ X% of all DNS queries over Y seconds are errors. Before that, it
+ only took 1 timeout to report the overload state which was just
+ too low of a threshold. The X and Y values are 1% and 10 minutes
+ respectively but they are also controlled by consensus parameters.
+ Fixes bug 40491; bugfix on 0.4.6.1-alpha.
+
+ o Minor features (bridge):
+ - We now announce the URL to Tor's new bridge status at
+ https://bridges.torproject.org/ when Tor is configured to run as a
+ bridge relay. Closes ticket 30477.
+
+ o Minor features (fallbackdir):
+ - Regenerate fallback directories for October 2021. Close
+ ticket 40493.
+
+ o Minor features (testing):
+ - On a testing network, relays can now use the
+ TestingMinTimeToReportBandwidth option to change the smallest
+ amount of time over which they're willing to report their observed
+ maximum bandwidth. Previously, this was fixed at 1 day. For
+ safety, values under 2 hours are only supported on testing
+ networks. Part of a fix for ticket 40337.
+ - Relays on testing networks no longer rate-limit how frequently
+ they are willing to report new bandwidth measurements. Part of a
+ fix for ticket 40337.
+ - Relays on testing networks now report their observed bandwidths
+ immediately from startup. Previously, they waited until they had
+ been running for a full day. Closes ticket 40337.
+
+ o Minor bugfix (onion service):
+ - Do not flag an HSDir as non-running in case the descriptor upload
+ or fetch fails. An onion service closes pending directory
+ connections before uploading a new descriptor which can thus lead
+ to wrongly flagging many relays and thus affecting circuit building
+ path selection. Fixes bug 40434; bugfix on 0.2.0.13-alpha.
+ - Improve logging when a bad HS version is given. Fixes bug 40476;
+ bugfix on 0.4.6.1-alpha.
+
+ o Minor bugfixes (compatibility):
+ - Fix compatibility with the most recent Libevent versions, which no
+ longer have an evdns_set_random_bytes() function. Because this
+ function has been a no-op since Libevent 2.0.4-alpha, it is safe
+ for us to just stop calling it. Fixes bug 40371; bugfix
+ on 0.2.1.7-alpha.
+
+ o Minor bugfixes (onion service, TROVE-2021-008):
+ - Only log once any v2 access attempts in order to not pollute the
+ logs with warnings and avoid recording the times on disk when v2
+ access was attempted. Important to note that the onion address was
+ _never_ logged. That is a Low security issue. Fixes bug 40474;
+ bugfix on 0.4.5.8.
+
