nginx 0.6.27
*) Change: now by default the rtsig method is not built on
Linux 2.6.18+.
*) Change: now a request method is not changed while redirection to a
named location via an "error_page" directive.
*) Feature: the "resolver" and "resolver_timeout" directives in SMTP
proxy.
*) Feature: the "post_action" directive supports named locations.
*) Bugfix: a segmentation fault occurred in worker process, if a
request was redirected from proxy, FastCGI, or memcached location to
static named locations.
*) Bugfix: browsers did not repeat SSL handshake if there is no valid
client certificate in first handshake.
Thanks to Alexander V. Inyukhin.
*) Bugfix: if response code 495-497 was redirected via an "error_page"
directive without code change, then nginx tried to allocate too many
memory.
*) Bugfix: memory leak in long-lived non buffered connections.
*) Bugfix: memory leak in resolver.
*) Bugfix: a segmentation fault occurred in worker process, if a
request was redirected from proxy, FastCGI, or memcached location to
static named locations.
*) Bugfix: in the $proxy_host and $proxy_port variables caching.
Thanks to Sergey Bochenkov.
*) Bugfix: a "proxy_pass" directive with variables used incorrectly the
same port as in another "proxy_pass" directive with the same host
name and without variables.
Thanks to Sergey Bochenkov.
*) Bugfix: an alert "sendmsg() failed (9: Bad file descriptor)" on some
64-bit platforms while reconfiguration.
*) Bugfix: a segmentation fault occurred in worker process, if empty
stub block was used second time in SSI.
*) Bugfix: in copying URI part contained escaped symbols into arguments.
