After having some troubles with the last two packages, the new one should work smoothly.
4.5.1. is basically a bugfix package without major changes.
Dropbox Folder is already updated:
The package has been successfully uploaded to the community package hub and the update button appears soon.
For those of you, updating from 4.5.0: Please read the release announcement of the 4.5.1 package.
Have a nice Weekend and 1st Advent, Eric
