Changes with nginx 0.6.22 19 Dec 2007v0.6.22

    *) Change: now all ngx_http_perl_module methods return values copied to
       perl's allocated memory.

    *) Bugfix: if nginx was built with ngx_http_perl_module, the perl
       before 5.8.6 was used, and perl supported threads, then during
       reconfiguration the master process aborted; bug appeared in
       0.5.9.
       Thanks to Boris Zhmurov.

    *) Bugfix: the ngx_http_perl_module methods may get invalid values of
       the regex captures.

    *) Bugfix: a segmentation fault occurred in worker process, if the
       $r->has_request_body() method was called for a request whose small
       request body was already received.

    *) Bugfix: large_client_header_buffers did not freed before going to
       keep-alive state.
       Thanks to Olexander Shtepa.

    *) Bugfix: the last address was missed in the $upstream_addr variable;
       bug appeared in 0.6.18.

    *) Bugfix: the "fastcgi_catch_stderr" directive did return error code;
       now it returns 502 code, that can be rerouted to a next server using
       the "fastcgi_next_upstream invalid_header" directive.

    *) Bugfix: a segmentation fault occurred in master process if the
       "fastcgi_catch_stderr" directive was used; bug appeared in
       0.6.10.
       Thanks to Manlio Perillo.
