Just finished up the last(?) bug reports for 5.01 - date picker wasn't working ok and there was an error when previewing a textad banner in admin GUI of the banner wasn't made active.
I will now start updating the docs to include the new functionality and after that, yes, we will release it for the public. Existing customers will be able to do a simple upgrade patch by :
1. applying a single database script
2. copying some files (dll:s and some aspx)
