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.
