+Changes in version 0.3.2.7-rc - 2017-12-1?
+ Tor 0.3.2.7-rc fixes various bugs in earlier versions of Tor, including
+ some that could affect reliability or correctness.
+
+ This is the first release candidate in the 0.3.2 series. If we find no
+ new bugs or regression here, then the first stable 0.3.2. release will be
+ nearly identical to this.
+
+ o Major bugfixes (circuit prediction):
+ - Fix circuit prediction logic so that a client doesn't treat a stream as
+ being "handled" by a circuit if that circuit already has isolation
+ settings on it that might make it incompatible with the stream. This
+ change should make Tor clients more responsive by improving their
+ chances of having a pre-created circuit ready for use when a new client
+ request arrives. Fixes bug 18859; bugfix on 0.2.3.3-alpha.
+
+ o Minor features (logging):
+ - Provide better warnings when the getrandom() syscall fails.
+ Closes ticket 24500.
+
+ o Minor features (portability):
+ - Tor now compiles correctly on arm64 with libseccomp-dev installed.
+ (It doesn't yet work with the sandbox enabled.) Closes ticket 24424.
+
+ o Minor bugfix (KIST scheduler):
+ - Downgrade a warning to log info when the monotonic time diff is
+ negative. This can happen on platform not supporting monotonic time. The
+ scheduler recovers from this without any problem. Fixes bug 23696;
+ bugfix on 0.3.2.1-alpha.
+
+ o Minor bugfixes (bridge clients, bootstrap):
+ - Retry directory downloads when we get our first bridge descriptor
+ during bootstrap or while reconnecting to the network. Keep retrying
+ every time we get a bridge descriptor, until we have a reachable bridge.
+ Fixes bug 24367; bugfix on 0.2.0.3-alpha.
+ - Stop delaying bridge descriptor fetches when we have cached bridge
+ descriptors. Instead, only delay bridge descriptor fetches when we
+ have at least one reachable bridge.
+ Fixes bug 24367; bugfix on 0.2.0.3-alpha.
+ - Stop delaying directory fetches when we have cached bridge descriptors.
+ Instead, only delay bridge descriptor fetches when all our bridges are
+ definitely unreachable.
+ Fixes bug 24367; bugfix on 0.2.0.3-alpha.
+
+ o Minor bugfixes (compilation):
+ - Fix a signed/unsigned comparison warning introduced by our
+ fix to TROVE-2017-009. Fixes bug 24480; bugfix on 0.2.5.16.
+
+ o Minor bugfixes (correctness):
+ - Fix several places in our codebase where a C compiler would be likely
+ to eliminate a check, based on assuming that undefined behavior had not
+ happened elsewhere in the code. These cases are usually a sign of
+ redundant checking, or dubious arithmetic. Found by Georg Koppen using
+ the "STACK" tool from Wang, Zeldovich, Kaashoek, and
+ Solar-Lezama. Fixes bug 24423; bugfix on various Tor versions.
+
+ o Minor bugfixes (hidden service v3):
+ - Fix a race between the circuit close and free where the service would
+ launch a new intro circuit after the close, and then fail to register it
+ before the free of the previously closed circuit. This was making the
+ service unable to find the established intro circuit and thus not upload
+ its descriptor. It can make a service unavailable for up to 24 hours.
+ Fixes bug 23603; bugfix on 0.3.2.1-alpha.
+
+ o Minor bugfixes (scheduler):
+ - Properly set the scheduler state of an unopened channel in the KIST
+ scheduler main loop. This prevents a harmless but annoying log warning.
+ Fixes bug 24502; bugfix on 0.3.2.4-alpha.
+
+ o Minor bugfixes (scheduler, KIST):
+ - Avoid a possible integer overflow when computing the available space on
+ the TCP buffer of a channel. This has no security implications but can
+ make KIST not behave properly by allowing more cells on a already
+ saturated connection. Fixes bug 24590; bugfix on 0.3.2.1-alpha.
