+Changes in version 0.4.6.7 - 2021-08-16
+ This version fixes several bugs from earlier versions of Tor,
+ including one that could lead to a denial-of-service attack. Everyone
+ running an earlier version, whether as a client, a relay, or an onion
+ service, should upgrade to Tor 0.3.5.16, 0.4.5.10, or 0.4.6.7.
+
+ o Major bugfixes (cryptography, security):
+ - Resolve an assertion failure caused by a behavior mismatch between
+ our batch-signature verification code and our single-signature
+ verification code. This assertion failure could be triggered
+ remotely, leading to a denial of service attack. We fix this issue
+ by disabling batch verification. Fixes bug 40078; bugfix on
+ 0.2.6.1-alpha. This issue is also tracked as TROVE-2021-007 and
+ CVE-2021-38385. Found by Henry de Valence.
+
+ o Minor feature (fallbackdir):
+ - Regenerate fallback directories list. Close ticket 40447.
+
+ o Minor features (geoip data):
+ - Update the geoip files to match the IPFire Location Database, as
+ retrieved on 2021/08/12.
+
+ o Minor bugfix (crypto):
+ - Disable the unused batch verification feature of ed25519-donna.
+ Fixes bug 40078; bugfix on 0.2.6.1-alpha. Found by Henry
+ de Valence.
+
+ o Minor bugfixes (onion service):
+ - Send back the extended SOCKS error 0xF6 (Onion Service Invalid
+ Address) for a v2 onion address. Fixes bug 40421; bugfix
+ on 0.4.6.2-alpha.
+
+ o Minor bugfixes (relay):
+ - Reduce the compression level for data streaming from HIGH to LOW
+ in order to reduce CPU load on the directory relays. Fixes bug
+ 40301; bugfix on 0.3.5.1-alpha.
+
+ o Minor bugfixes (timekeeping):
+ - Calculate the time of day correctly on systems where the time_t
+ type includes leap seconds. (This is not the case on most
+ operating systems, but on those where it occurs, our tor_timegm
+ function did not correctly invert the system's gmtime function,
+ which could result in assertion failures when calculating voting
+ schedules.) Fixes bug 40383; bugfix on 0.2.0.3-alpha.

+ - Enable the deterministic RNG for unit tests that covers the
+ address set bloomfilter-based API's. Fixes bug 40419; bugfix
+ on 0.3.3.2-alpha.
+
+ o Minor bugfix (crypto, backport from 0.4.6.7):

+
+ o Minor bugfixes (warnings, portability, backport from 0.4.6.6):
+ - Suppress a strict-prototype warning when building with some
+ versions of NSS. Fixes bug 40409; bugfix on 0.3.5.1-alpha.
