Changes in version 0.1.2.2-alpha - 2006-??-??
o Major features:
- Add server-side support for "reverse" DNS lookups (using PTR
- records so clients can determine the canonical hostname for a given
- IPv4 address). This has been specified for a long time, but was
- previously never implemented. This is only supported by eventdns;
- servers now announce in their descriptors whether they support
- eventdns.

+ given IPv4 address). This has been specified for a long time,

+ eventdns; servers now announce in their descriptors whether they
+ support eventdns.
- Specify and implement client-side SOCKS5 interface for reverse DNS
lookups; see doc/socks-extensions.txt for full information.
o Minor features:
- Check for name servers (like Earthlink's) that hijack failing DNS
- requests and replace the 'no such server' answer with a "helpful"
- redirect to an advertising-driven search portal. We're a little clever
- about this, in order to work around DNS hijackers who "helpfully"
- decline to hijack known-invalid RFC2606 addresses. [Resolves bug 330.]

+ Config option "ServerDNSDetectHijacking 0" lets you turn it off.
- When asked to resolve a hostname, don't use non-exit servers unless
- requested to do so. This allows servers with broken DNS be useful to
- the network.

+ - Fix NetBSD bug that could allow someone to force uninitialized RAM
+ to be sent to a server's DNS resolver. This only affects NetBSD
+ and other platforms that do not bounds-check tolower().
- o Major bugfixes
- - When a client asks us to resolve (not connect to) an address,
- and we have a cached answer, give them the cached answer.
- Previously, we would give them no answer at all.
-
- o Minor Bugfixes
- - Small performance improvements on parsing descriptors (x2).
- - Major performance descriptor on inserting descriptors; change
+ o Major bugfixes:
+ - Avoiding crashing on race condition in dns.c:
+ tor_assert(! resolve->expire)
+ - When a client asks the server to resolve (not connect to)
+ an address, and it has a cached answer, give them the cached answer.
+ Previously, the server would give them no answer at all.
+
+ o Minor Bugfixes:
+ - Two small performance improvements on parsing descriptors.
+ - Major performance improvement on inserting descriptors: change
algorithm from O(n^2) to O(n).
- Make the common memory allocation path faster on machines where
malloc(0) returns a pointer.
- Fix a debug log message in eventdns to say "X resolved to Y"
instead of "X resolved to X".
- - Prevent the 'exitlist' script from printing the same result more
- than once.
- - Build correctly for use on OS X platforms with case-sensitive
- filesystems.
+ - Prevent the contrib/exitlist script from printing the same
+ result more than once.
+ - Resume building on non-gcc compilers and ancient gcc. Resume
+ building with the -O0 compile flag. Resume building cleanly on
+ Debian woody.
+ - Correct includes for net/if.h and net/pfvar.h on OpenBSD (from Tup).
+ - Improve Tor's chances of building and running on Cygwin again.
+ - If we're a directory mirror and we ask for "all" network status
+ documents, we would discard status documents from authorities
+ we don't recognize.
o Documentation
- Documented (and renamed) ServerDNSSearchDomains and
ServerDNSResolvConfFile options.
+
+
+ o Packaging:
+ - Patches so Tor builds with MinGW on Windows.
+ - The Debian package now uses --verify-config when (re)starting,
+ to distinguish configuration errors from other errors.
+ - Update rpms to require libevent 1.1b.
+ - Remove architecture from OS X builds. The official builds are
+ now universal binaries.
+
+ - Make eventdns on-by-default.
+ - Divide eventdns log messages into warn and info messages.
+ - Add new config option "ResolvConf" to let the server operator
+ choose an alternate resolve.conf file.
+
+ - Allow really slow clients to not hang up five minutes into their
+ directory downloads (suggested by Adam J. Richter).
+ - Apply patch from Adam Langley: fix assert() in eventdns.c.
+ - Finally fix the openssl warnings with newer gccs that believe that
+ ignoring a return value is okay, but casting a return value and
+ then ignoring it is a sign of madness.
+ - Don't crash when the controller receives a third argument to an
+ "extendcircuit" request.
+ - Add a "getinfo address" controller command.
+ - Controller protocol fixes: fix encoding in "getinfo addr-mappings"
+ response; fix error code when "getinfo dir/status/" fails.
+ - Start remembering X-Your-Address-Is directory hints even if you're
+ a client, so you can become a server more smoothly.
+ - Avoid crash when telling controller stream-status and a stream
+ is detached.
+ - Avoid crashing when we mmap a router cache file of size 0.
+ - Avoid duplicate entries on MyFamily line in server descriptor.
+ - Patch from Steve Hildrey: Generate network status correctly on
+ non-versioning dirservers.
+ - Send out a burst of long-range drop cells after we've established
+ that we're reachable. Spread them over 4 circuits, so hopefully
+ a few will be fast. This exercises our bandwidth and bootstraps
+ us quicker.
+ - Remove 8888 as a long lived port, and add 6697 (ircs).

Changes in version 0.1.2.1-alpha - 2006-08-27
o Major features:
- Add "eventdns" async dns library from Adam Langley, tweaked to
