  1. @stuart We are no longer waiting for the CDNs to update prior to our announcements. Doing so has caused anywhere from a week to a month delay. The code is available via GitHub, the jQuery CDN, and Download Builder.

  2. Fixed: Sortable “Connect Lists” demo doesn’t allow dropping as last element. (#8114, fff9d87)
    Thanks for fixing this. I had applied a similar fix to my environment.

    Fixed: a major optimization is possible in sortable(). (#4759, b00faa9)
    Hurray! Previously it was common to set connected lists after initialization to gain this optimization.

  3. Hi Scott,

    Great stuff as ever! Just wondered if I could get a bit more detail about 1.9? There’s been a number of milestone releases so far and you mention that one more is on the way. Is that likely to be the last milestone release before a full beta? Or is that not clear at the moment?

    I’m very keen to make use of the menu and tooltip widgets….

  4. Why the combined nuget package of this release does not contain the minified css anymore?
