The Tool Updater always wants to update, even if the newest version is already installed.
To reproduce, download any of my tools (http://renoise.com/tools/split-into-separate-tracks orhttp://renoise.com/tools/track-comments), install it, and run the tool update. It will tell you that a new version (the one you just installed) is available. This message does not go away, even if you update again via the updater.
What is going on there? Am I doing something wrong in my tools?
