Hi Greg, When updating the version number of a tool I noticed that, as expected, both the old version and the new version of the tool become available in the Galaxy environment. What I did not expect is that the new version resulted in a new entry in the menu bar (see screenshot): [cid:image001.png@01CEB07A.3ECB90B0] If I remember correctly, you showed in Oslo that the tool version becomes a choice in the tool itself, something like the screenshot below: [cid:image002.png@01CEB07A.9929B870] Is this a setting somewhere or are we facing a bug?
