The support for running multiple Rails
applications on one vhost has been improved.
Bugfixes were made to the upload-handler, webdav,
proxy, auth, and other modules.

The performance for highly-concurrent, large-file downloads has been
improved by adding better read-ahead handling. It is now up to the
user to choose internal read-ahead via mmap()+writev() or kernel-based
high-perf sendfile() handling. The problems with MSIE and SSL have been
worked around; the upload temp-dir is now a set of directories to have a
fallback if one of the disks is full.

Compilation under Mac OS X was fixed and the mod_mysql_vhost plugin now works again. The compressed output of mod_compress is now accepted by IE and Opera again.

This release fixes segfaults in some modules, and solves a starvation problem that might have been an issue for high traffic sites where the accept() loop optimization turned into a starvation of waiting connections. The upload problem is fixed by buffering larger uploads to disk. This helps to keep the memory usage as low as possible, even for larger uploads.

mod_auth can handle md5 and blowfish hashes in htpasswd files, and a mem-leak was fixed in the stat-cache. A FastCGI backend can trigger a static file transfer, replacing a readfile() call on the PHP side.
