+- Improved DEBUG handling with two different modes. `DEBUG=0` is still for production, and `1` is still for the DEBUG we previously knew downloading to the directory it is running from, but `2` will download to temporary folder, will detect updates, but will not install anything, but it will notify the user.

 ## v0.7
 
 - default for `BLOCKING_PROCESS_ACTION`is now `BLOCKING_PROCESS_ACTION=tell_user` and not `prompt_user`. It will demand the user to quit the app to get it updated, and not present any option to skip it. In considering various use cases in different MDM solutions this is the best option going forward. Users usually choose to update, and is most often not bothered much with this information. If it's absoultely a bad time, then they can move the dialog box to the side, and click it when ready.
