This release adds many features including result sorting in the DNS/hosts
resolver modeled on RFC 3484, default timezone from /etc/localtime, gnu2
TLS dialect (TLSDESC) on i386 and x86_64, sendmmsg/recvmmsg functions
(Linux extensions), fmtmsg function (XSI), and optional arguments in getopt
(GNU extension). Handling of poorly-behaved nameservers (rcode=2 ServFail
result) is also improved, and setting of the %gs thread register is now
supported on pre-2.6 i386 kernels. Several bugs are fixed including a
potentially-important issue in memmem.
