nginx-0.3.13-RELEASE import *) Feature: the IMAP/POP3 proxy supports STARTTLS and STLS. *) Bugfix: the IMAP/POP3 proxy did not work with the select, poll, and /dev/poll methods. *) Bugfix: in SSI handling. *) Bugfix: now Solaris sendfilev() is not used to transfer the client request body to FastCGI-server via the unix domain socket. *) Bugfix: the "auth_basic" directive did not disable the authorization; the bug had appeared in 0.3.11.
