Apple has released Web Sharing Update 1.0 for Mac OS X.
The update is available using the Software Updates Control Panel in OS X, but not yet from Apple's software-update Web pages.
In the update's Read Me file, Apple explains that the update delivers feature and security enhancements to Apache, the open-source Web server used by OS X. It adds support for case-insensitive Mac OS Extended file system, and the latest version of OpenSSH.
SSH (Secure Shell) is a command interface and protocol for getting access securely to a remote computer. It is widely used by network administrators to control remotely Web and other kinds of servers.
