New Server just $20 add-on
(Updated with Safari security notes) Accompanying today's launch of OS X Mountain Lion are a number of parallel software updates. Amount these is OS X Server for Mountain Lion, a $20 add-on. The release marks another price drop for Server, which in its Lion form cost $49; before that it cost several times more still.
Apple has also updated the core apps of the iWork suite -- Pages, Numbers, and Keynote -- to complement Mountain Lion's new features. This includes deeper iCloud integration, specifically the expansion of Documents in the Cloud, as well as Dictation support. The programs have additionally received graphical updates to match the MacBook Pro's Retina display.
One component of Mountain Lion, Safari 6, has also been ported back to OS X Lion, minus features exclusive to Mountain Lion such as iCloud Tabs and integrated sharing. That leaves the Smart Search Field, Do Not Track, the offline Reading List, and the Password pane as Lion additions, alongside Baidu search support for Chinese users.
Update: Safari 6 for Lion also fixes a number of security flaws. Among these are bad handling of of feed:// URLs, passwords autocompleting even when a site says the feature should be disabled, and an HTTP header glitch allowing unintended access to files on a server. Numerous WebKit vulnerabilities have likewise been closed.
