*) Bugfix: the segmentation fault occurred when the signal queue
       overflowed if the "rtsig" method was used; the bug had appeared in
       0.2.0.

    *) Change: correct handling of the "\\", "\"", "\'", and "\$" pairs in
       SSI.

    *) Change: the 10-days live time limit of worker process was
       eliminated. The limit was introduced because of millisecond timers
       overflow.

    *) Change: while using load-balancing the time before the failed
       backend retry was decreased from 60 to 10 seconds.

    *) Change: the "proxy_pass_unparsed_uri" was canceled, the original URI
       now passed, if the URI part is omitted in "proxy_pass" directive.

    *) Feature: the "error_page" directive supports redirects and allows
       more flexible to change an error code.

    *) Change: the charset in the "Content-Type" header line now is ignored
       in proxied subrequests.

    *) Bugfix: if the URI was changed in the "if" block and request did not
       found new configuration, then the ngx_http_rewrite_module rules ran
       again.

    *) Bugfix: if the "set" directive set the ngx_http_geo_module variable
       in some configuration part, the this variable was not available in
       other configuration parts and the "using uninitialized variable"
       error was occurred; the bug had appeared in 0.2.2.

    *) Change: the duplicate value of the ngx_http_geo_module variable now
       causes the warning and changes old value.

    *) Feature: the ngx_http_ssi_module supports the "set" command.

    *) Feature: the ngx_http_ssi_module supports the "file" parameter in
       the "include" command.

    *) Feature: the ngx_http_ssi_module supports the variable value
       substitutions in expressions of the "if" command.

    *) Feature: the ngx_http_ssi_module supports "$var=text", "$var!=text",
       "$var=/text/", and "$var!=/text/" expressions in the "if" command.

    *) Bugfix: in proxying location without trailing slash; the bug had
       appeared in 0.1.44.

    *) Bugfix: the segmentation fault may occurred if the "rtsig" method
       was used; the bug had appeared in 0.2.0.

    *) Feature: the "config errmsg" command of the ngx_http_ssi_module.

    *) Change: the ngx_http_geo_module variables can be overridden by the
       "set" directive.

    *) Feature: the "ssl_protocols" and "ssl_prefer_server_ciphers"
       directives of the ngx_http_ssl_module and ngx_imap_ssl_module.

    *) The pid-file names used during online upgrade was changed and now is
       not required a manual rename operation. The old master process adds
       the ".oldbin" suffix to its pid-file and executes a new binary file.
       The new master process creates usual pid-file without the ".newbin"
       suffix. If the master process exits, then old master process renames
       back its pid-file with the ".oldbin" suffix to the pid-file without
       suffix.

    *) Change: the "worker_connections" directive, new name of the
       "connections" directive; now the directive specifies maximum number
       of connections, but not maximum socket descriptor number.

       error, then nginx did not try do connect to them during 60 seconds.

    *) Bugfix: in IMAP/POP3 command argument parsing.
       Thanks to Rob Mueller.

    *) Bugfix: errors while using SSL in IMAP/POP3 proxy.

    *) Bugfix: errors while using SSI and gzipping.

       the "Cache-Control" header line and the "expires" directive was
       used; in the proxied mode the the bug had appeared in 0.1.29.
