Hi. I have a feedback about Package Manager versioning system. Currently, Package manager allows only "X.Y.Z" or "X.Y.Z-preview" or "X.Y.Z-preview.N". And "-preview" has low priority for update button (ex, Package manager suggests updating 1.0.0-preview to 1.0.0 but reverse is not) But for custom package, if you create open source library as your custom package, usually you want to set package's version to same as original library's version. But also you need to apply some unity specific modification to your custom package. In this case, specific prefix is needed like "1.2.1-patch.1" or "1.2.1-hotfix.2". and Package Manager should suggests that "1.2.1" can be updated to "1.2.1-patch.1". I think this makes Package Manager more comfortable to developers. Thanks.
