Changes in version 0.2.2.14-alpha - 2010-07-1?
Changes in version 0.2.2.14-alpha - 2010-07-12
o Major bugfixes:
- Tor directory authorities no longer crash when started with a
cached-microdesc-consensus file in their data directory. Bugfix

happen during a suspend or hibernate. These values caused various
asserts to fire. Bugfix on 0.2.2.2-alpha; fixes bug 1245.
- Alter calculation of Pareto distribution parameter 'Xm' for
Circuit Build Timeout learning to use the weighted average of
the top N=3 modes, because we have three entry guards. This should
improve the timeout calculation in some cases, and prevent extremely
high timeout values. Bugfix on 0.2.2.2-alpha; fixes bug 1335.
Circuit Build Timeout learning to use the weighted average of the
top N=3 modes (because we have three entry guards). Considering
multiple modes should improve the timeout calculation in some cases,
and prevent extremely high timeout values. Bugfix on 0.2.2.2-alpha;
fixes bug 1335.
- Alter calculation of Pareto distribution parameter 'Alpha' to use a
right censored distribution model. This allows us to remove
the synthetic timeout generation and instead calculate build
timeouts using truncated times. Bugfix on 0.2.2.2-alpha; fixes
bugs 1245+1335.
- Keep circuits open (but do not use them) after the circuit
timeout for up until the time corresponding to the 95th percentile
right censored distribution model. This approach improves over the
synthetic timeout generation approach that was producing insanely
high timeout values. Now we calculate build timeouts using truncated
times. Bugfix on 0.2.2.2-alpha; fixes bugs 1245 and 1335.
- Do not close circuits that are under construction when they reach
the circuit build timeout. Instead, leave them building (but do not
use them) for up until the time corresponding to the 95th percentile
on the Pareto CDF or 60 seconds, whichever is greater. This is done
to provide better data for the new Pareto model. This percentile
can be controlled by the consensus.

more accurate data for many African countries.
- Port Tor to build and run correctly on Windows CE systems, using
the wcecompat library. Contributed by Valerio Lupi.
- New "--enable-gcc-hardening" ./configure flag to turn on gcc
compile time hardening options. It ensures that signed ints have
defined behavior (-fwrapv), -D_FORTIFY_SOURCE=2 is enabled
(requiring -O2), stack smashing protection with canaries
(-fstack-protector-all), ASLR protection if supported by the
kernel (-fPIE, -pie). Additional security related warnings are
enabled. Verified to work on Mac OS X and Debian Lenny.
- New "--enable-linker-hardening" ./configure flag to turn on ELF
specific hardening features (relro, now). This does not work with
Mac OS X or any other non-ELF binary format.
- New "--enable-gcc-hardening" ./configure flag (off by default)
to turn on gcc compile time hardening options. It ensures
that signed ints have defined behavior (-fwrapv), enables
-D_FORTIFY_SOURCE=2 (requiring -O2), adds stack smashing protection
with canaries (-fstack-protector-all), turns on ASLR protection if
supported by the kernel (-fPIE, -pie), and adds additional security
related warnings. Verified to work on Mac OS X and Debian Lenny.

- More gracefully handle corrupt state files, removing asserts
in favor of saving a backup and resetting state.
- Rename the "log.h" header to "torlog.h" so as to conflict with fewer
system headers.
o Minor bugfixes:
- Build correctly on OSX with zlib 1.2.4 and higher with all warnings
