nginx-0.1.2-RELEASE import *) Feature: the --user=USER, --group=GROUP, and --with-ld-opt=OPTIONS options in configure. *) Feature: the server_name directive supports *.domain.tld. *) Bugfix: the portability improvements. *) Bugfix: if configuration file was set in command line, the reconfiguration was impossible; the bug had appeared in 0.1.1. *) Bugfix: proxy module may get caught in an endless loop when sendfile is not used. *) Bugfix: with sendfile the response was not recoded according to the charset module directives; the bug had appeared in 0.1.1. *) Bugfix: very seldom bug in the kqueue processing. *) Bugfix: the gzip module compressed the proxied responses that was already compressed.
