Reading the source code, it looks like:
- Name
- Package
- Menu
- Shortcut
- Event
- Loaded
- Active
- RV Version
- Optional
- (Requires if specified)
So In RV 4+ it appears that the number is the minimum version of RV that is required to run the package. If you check out the PACKAGE file for the associated package, does the value for the rv
key exist?
When a package has a greater version number than the version of RV you are running, the package will not be loaded.
