nginx 1.3.5 *) Change: the ngx_http_mp4_module module no longer skips tracks in formats other than H.264 and AAC. *) Bugfix: a segmentation fault might occur in a worker process if the "map" directive was used with variables as values. *) Bugfix: a segmentation fault might occur in a worker process if the "geo" directive was used with the "ranges" parameter but without the "default" parameter; the bug had appeared in 0.8.43. Thanks to Zhen Chen and Weibin Yao. *) Bugfix: in the -p command-line parameter handling. *) Bugfix: in the mail proxy server. *) Bugfix: of minor potential bugs.
