Lately, we have released Geta Tags 4.0.1. The new release has several breaking changes.
In the new version, we have removed obsolete APIs which used PageReference, PageDataCollection and getting pages by page GUIDs. Instead of these, you should use new content APIs.
Another breaking change is related to methods which return IEnumerable. Previously, these methods might return null. Now those will always return some value. If nothing found, will return an empty enumerable instead of null.
The package with version 4.0.1 also includes a bug fix. It fixed the multi-language issue when tag changes in one language removed tags in another language.
You can install the new package from the Package Manager Console using Episerver NuGet Feed.
