This is mostly a bug-fix release, with a few enhancements as well.

The primary enhancement is the addition of version 2.3 of the Speech-Rule Engine that underlies the accessibility tools. This includes performance enhancements as well as a Spanish localization that is tied to the MathJax localization menu. In addition, the Explorer menu in the Assistive submenu has been slimmed down to remove unneeded options.
