"References to an older version of the SDL API assemblies"

Question

When I start Studio, I get messages that "The plug-in defined in "Sdl.CommunityTransPDF.plugin.xml" contains references to an older version of the SDL API assemblies." See below. 
 
 I suppose this means that I should download newer versions of AppStore plugins. But which ones? I get the same message about CLGWTranslationProvider.plugin.xlm (SDL Assembly Name: Sdl.LanguagePlatform.TranslationMemoryApi). 
 File searches give no results.

Hi Mats Linder 
 
This means you have installed a plugin that has not been updated for 2019 (most likely). All developers were provided with instructions on how to update their apps and most have done. Looks like the Iceni guys have not. You should contact them and refer to this article:
