When I want to create a deployment package in the Developer Portal, it automatically sets the version number to the highest version ever created in that app. This is fine unless someone makes a mistake when incrementing the version number, especially the major number.
I have tried deleting the tags from SVN, but this does not appear to make any difference, so a feature to make it check again would be good. In fact, if it could default to the last version number used in that branch, it would be even better.
