The biggest bug fix in this release has to do with iCal feeds.  Our iCal code is now tested and much more robust and correct than before.  If a snippet was empty, then it would ask you to add a page with the same URL that it uses.  This has been fixed.  Empty snippets now just send you no content.  There was a bug fixed in the 7.6.25 to .26 upgrade having to do with cleaning out old AddressBooks.  Unless you use the Shop and have users who have deleted their accounts you will not come across this bug.  The Collaboration System is now more tolerant of UTF-8 characters when autogenerating a synopsis.  A rendering issue was fixed in the Thingy where the Cancel and Submit buttons were hidden.

Gotchas:

   * It was mistakenly reported that 7.6.29 would be a stop version for
     upgrades.  This is incorrect.  7.6.29 is not a stop version.
