Luckily I'm one of the individuals that upgrades non-production blogs before upgrading my clients and my own production wordpress installations. Right now the majority of any JQuery enabled features within the dashboard are broken.
This means all AJAX enabled submission (updating tags, adding categories) and functionality (lightbox/thickbox, etc) is reporting errors. This is across all three major browsers Firefox, IE, and Chrome.
I am not looking for community support, I'm looking for Automattic developers to acknowledge and release a fix. Uninstalling and reinstalling 30+ production installations with all of their individual plugins and settings is not a realistic answer.
