*) Feature: the ngx_http_map_module. *) Feature: the "types_hash_max_size" and "types_hash_bucket_size" directives. *) Feature: the "ssi_value_length" directive. *) Feature: the "worker_rlimit_core" directive. *) Workaround: the connection number in logs was always 1 if nginx was built by the icc 8.1 or 9.0 compilers with optimization for Pentium 4. *) Bugfix: the "config timefmt" SSI command set incorrect time format. *) Bugfix: nginx did not close connection to IMAP/POP3 backend for the SSL connections; the bug had appeared in 0.3.13. Thanks to Rob Mueller. *) Bugfix: segmentation fault may occurred in at SSL shutdown; the bug had appeared in 0.3.13.
