nginx 1.0.1
*) Change: now the "split_clients" directive uses MurmurHash2 algorithm
because of better distribution.
Thanks to Oleg Mamontov.
*) Change: now long strings starting with zero are not considered as
false values.
Thanks to Maxim Dounin.
*) Change: now nginx uses a default listen backlog value 511 on Linux.
*) Feature: the $upstream_... variables may be used in the SSI and perl
modules.
*) Bugfix: now nginx limits better disk cache size.
Thanks to Oleg Mamontov.
*) Bugfix: a segmentation fault might occur while parsing incorrect
IPv4 address; the bug had appeared in 0.9.3.
Thanks to Maxim Dounin.
*) Bugfix: nginx could not be built by gcc 4.6 without --with-debug
option.
*) Bugfix: nginx could not be built on Solaris 9 and earlier; the bug
had appeared in 0.9.3.
Thanks to Dagobert Michelsen.
*) Bugfix: $request_time variable had invalid values if subrequests
were used; the bug had appeared in 0.8.47.
Thanks to Igor A. Valcov.
