UDM v4.6 is available!

This extensive release consolidates support for recent versions of all major web browsers. In addition, it brings a number of bugfixes and extension updates for smoother navigation and better display of menus and tooltips.

Version 4.6 adds/confirms support for the following new browsers:

  • IE8
  • Google Chrome
  • Firefox 3
  • Opera 9/10
  • Safari 3/4/5
  • Konqueror 4

This version also includes the following, unrelated bugfixes:

  • extended full arrow-key navigation to Konqueror 4.0 or later
  • fixed an arrow-position bug in IE7 with right-aligned horizontal navbars
  • fixed the auto-sizing menus extension, so that additional leeway space is not added to first-level menus of a horizontal navbar if they’re sized to match their parent link
  • fixed a bug with the you-are-here extension in all versions of IE so that here-indicated links have the correct arrow-rollover
  • added support for the onfocus tooltips extension to Opera 9 or later, Safari 3 or later, and Google Chrome
  • added support for the sliding menus extension to Konqueror 4

There’s one significant change to the Keyboard navigation module:

  • changed the default keyboard navigation hotkey from F12 to F8 because F12 is used by default by Expose in OSX. The new value works in all browsers that support full keyboard navigation, without any native conflict. Existing implementations can make this change by modifying the 5th value in um.keys (keyboard navigation hotkey) from “123″ to “119″
