Hi Folks,


Hope testing is going well!


We’ve just submitted a change to correct a few unit test compiler warnings and memory leaks recently introduced but nothing which impacts core code so there’s no current reason to extend the RC window.


Just a reminder that we’re going into the final week of testing here so if anyone has spotted anything unusual please speak up now if you want a fix to make it into this release!
