clean up the 0.2.2.1-alpha changelog entry

parent c3274c4c
Changes in version 0.2.2.1-alpha - 2009-??-??
o Security fixes:
- Fix an edge case where a malicious exit relay could convince a
controller that the client's DNS question resolves to an internal IP
address. Bug found and fixed by "optimist"; bugfix on 0.1.2.8-beta.
Changes in version 0.2.2.1-alpha - 2009-07-2?
o Major features:
- Add support for dynamic OpenSSL hardware crypto acceleration engines
via new AccelName and AccelDir options.
o New options for gathering stats safely:
- Directories that configure with --enable-dirreq-stats and set
"DirReqStatistics 1" write directory request stats to disk every
24 hours. As compared to the --enable-geoip-stats flag in 0.2.1.x,
there are a few improvements: 1) stats are written to disk exactly
every 24 hours; 2) estimated shares of v2 and v3 requests are
determined as mean values, not at the end of a measurement period;
3) unresolved requests are listed with country code '??';
4) directories also measure download times.
- Exit nodes that configure with --enable-exit-stats and set
"ExitPortStatistics 1" write statistics on the number of exit
streams and transferred bytes per port to disk every 24 hours.
- Relays that configure with --enable-buffer-stats and set
"CellStatistics 1" write statistics to disk every 24 hours on how
long cells spend in their circuit queues.
- Entry nodes that configure with --enable-entry-stats and set
"EntryStatistics 1" write statistics to disk every 24 hours on
the rough number and origins of connecting clients.
o Minor features:
- New --digests command-line switch to output the digests of the
source files Tor was built with.

- The memarea code now uses a sentinel value at the end of each area
to make sure nothing writes beyond the end of an area. This might
help debug some conceivable causes of bug 930.
- Directories that are configured with the --enable-dirreq-stats flag
and have "DirReqStatistics 1" set write directory request stats to
disk every 24 hours. As compared to the --enable-geoip-stats flag
in 0.2.1.x, there are a few improvements: 1) stats are written to
disk exactly every 24 hours; 2) estimated shares of v2 and v3
requests are determined as mean values, not at the end of a
measurement period; 3) unresolved requests are listed with country
code '??'; 4) directories also measure download times.
- Exit nodes can write statistics on the number of exit streams and
transferred bytes per port to disk every 24 hours. To enable this,
run configure with the --enable-exit-stats option, and set
"ExitPortStatistics 1" in your torrc.
- Relays write statistics on how long cells spend in their circuit
queues to disk every 24 hours. To enable this, run configure with
the --enable-buffer-stats option, and set "CellStatistics 1" in your
torrc.
- Entry nodes can write statistics on the rough number and origins of
connecting clients to disk every 24 hours. To enable this, run
configure with the --enable-entry-stats option, and set
"EntryStatistics 1" in your torrc.
- Time and memory units in the configuration file can now be set to
fractional units. For example, "2.5 MB" is now a valid value for
AccountingMax.
o Minor bugfixes
- Hidden service clients didn't use a cached service descriptor that
was older than 15 minutes, but wouldn't fetch a new one either. Now,
use a cached descriptor no matter how old it is and only fetch a new
one when all introduction points fail. Fix for bug 997. Patch from
Marcus Griep.
- Fix refetching of hidden service descriptors when all introduction
points have turned out to not work. Fixes more of bug 997.
o Deprecated and removed features:
- The controller no longer accepts the old obsolete "addr-mappings/"
GETINFO value.
or "unregistered-servers-" GETINFO values.
- Hidden services no longer publish version 0 descriptors, and clients
do not request or use version 0 descriptors. However, the authorities
still accept and serve version 0 descriptors when contacted by older
