Changes in version 0.3.4.1-alpha - 2018-05-1?
XXX BLURB
Tor 0.3.4.1-alpha is the first release in the 0.3.4.x series. It
includes refactoring to begin reducing Tor's
binary size and idle CPU usage on mobile, along with prep work for new
bandwidth scanners, improvements
to the experimental "vanguards" feature, and numerous other small
features and bugfixes.

the granularity of our bandwidth calculations, and limit the
number of times that the Tor process needs to wake up when it is
idle. Closes ticket 25373.
- Move responsibility for many operations from a once-per-second
callback to a callback that is only scheduled as needed. Moving
this functionality has allowed us to disable the callback when
Tor's network is disabled. Once enough items are removed from our
once-per-second callback, we can eliminate it entirely to conserve
CPU when idle. The functionality removed includes: closing
connections, circuits, and channels (ticket 25932); consensus
voting (25937); flushing log callbacks (25951); honoring delayed
SIGNEWNYM requests (25949); rescanning the consensus cache
(25931); saving the state file to disk (25948); warning relay
operators about unreachable ports (25952); and keeping track of
Tor's uptime (26009).
o Major bugfixes (directory authorities, security):
- When directory authorities read a zero-byte bandwidth file, they

- Avoid a needless call to malloc() when processing an incoming
relay cell. Closes ticket 24914.
