    How to update umbraco 8.6.1 to 8.7

    I am in the process of migrating umbraco 8.6.1 to 8.7. I have updated all nuget packages. Is there anything else to do ? I could not find any migration notes...

    I get this error...

    mbraco.Core.Exceptions.BootFailedException: Boot failed. ---> System.Reflection.ReflectionTypeLoadException: Could not load all types from "Umbraco.Core, Version=8.0.0.0, Culture=neutral, PublicKeyToken=null" due to LoaderExceptions, skipping:
