If you looked (read) any of the posts you could have known that isn’t the case and that
all the things you mentioned are solved by the creator of the Rhythm package.
About the upgrading; you can allways try to manually ‘install’ the newer Package.
Manual installation;
- Download the package from https://dynamopackages.com/
- Unzip it
- In Dynamo go to Setting > Manage Node and Package Paths
and add the folder containing the unzipped folder of the Package
NB
I don’t know if this will cause any issues with older (or newer) versions of Packages already installed.
