= Features =
* Support listening/connect for IPv6 addresses.
(Hannu Krosing)
* Multiple listen addresses in 'listen_addr'. For each getaddrinfo()
is called, so names can also be used.
* console: Send PgBouncer version as 'server_version' to client.
= Important Fixes =
* Disable getaddrinfo_a() on glibc < 2.9 as it crashes on older versions.
Notable affected OS'es: RHEL/CentOS 5.x (glibc 2.5), Ubuntu 8.04 (glibc 2.7).
Also Debian/lenny (glibc 2.7) which has non-crashing getaddrinfo_a()
but we have no good way to detect it.
Please use libevent 2.x on such OS'es, fallback getaddrinfo_a() is not
meant for production systems. And read new 'DNS lookup support' section
in README to see how DNS backend is picked.
(Hubert Depesz Lubaczewski, Dominique Hermsdorff, David Sommerseth)
* Default to --enable-evdns if libevent 2.x is used.
* Turn on tcp_keepalive by default, as that's what Postgres also does.
(Hubert Depesz Lubaczewski)
* Set default server_reset_query to DISCARD ALL to be compatible
with Postgres by default.
* win32: Fix crashes with NULL unix socket addr.
(Hiroshi Saito)
* Fix autodb cleanup: old cleanup code was mixing up databases and pools
- as soon as one empty pool was found, the database was tagged as 'idle',
potentially later killing database with active users.

= Fixes =
* Make compat getaddrinfo_a() non-blocking, by using single parallel
thread to do lookups.
* Enable pthread compilation if compat getaddrinfo_a is used.
* release_server missed setting ->last_lifetime_disconnect on lifetime disconnect.
(Emmanuel Courreges)
* win32: fix auth file on DOS line endings - load_file() did not take
account of file shringage when loading.
(Rich Schaaf)
* <usual/endian.h>: add autoconf detection for enc/dec functions
so it would not create conflicts on BSD.
(James Pye)
* Don't crash when config file does not exist.
(Lou Picciano)
* Don't crash on DNS lookup failure when logging on noise level (-v -v).
(Hubert Depesz Lubaczewski, Dominique Hermsdorff)
* Use backticks instead of $(cmd) in find_modules.sh to make it more portable.
(Lou Picciano)
* Use 'awk' instead of 'sed' in find_modules.sh to make it more portable.
(Giorgio Valoti)
* Log active async DNS backend info on startup.
* Fix --disable-evdns to mean 'no' instead 'yes'.
* Mention in docs that -R requires unix_socket_dir.
* Discuss server_reset_query in faq.txt.
* Restore lost memset in slab allocator
* Various minor portability fixes in libusual.
