Just want to let you know that with Unity 2019.3 I always get an error if I try to update the package to 2.x. 1.3.3 works for me.
What error do you get?
btw just FYI, the package is still not available officially, I have to copy and paste the string in the manifest from your documentation for every new project.
same here, I’m stuck with performance testing api at version 1.3.3
all other packages are up to date.
Unity 2019.3.2f1
Error messages:

Hey,
Could you check your manifest.json if com.unity.test-framework.performance is added to testables? If that is the case just remove and it should work.
I tried getting latest 19.3, importing performance testing package from the package manager window, seems to work. 
btw just FYI, the package is still not available officially, I have to copy and paste the string in the manifest from your documentation for every new project.
with the release of 2.x we have whitelisted and it is now available through package manager window. It is still under preview so you will need to enable them. Open Package Manager → Advanced → Show Preview Packages → in search enter performance and it should find it
Still getting an error:
