Release notes

Sourced from actions/setup-dotnet's releases.

v3.0.0

This major release includes the following changes:

• #219 New input dotnet-quality was added in #315:

    - uses: actions/setup-dotnet@v3
      with:
        dotnet-version: '6.0.x'
        dotnet-quality: 'preview'
    - run: dotnet build <my project>

More in detail here.

• #241 The output variable dotnet-version which contains the installed by the action SDK version was added in #324:

    - uses: actions/setup-dotnet@v3
      id: cp310
      with:
        dotnet-version: '3.1.422'
    - run: echo '${{ steps.cp310.outputs.dotnet-version }}' # outputs 3.1.422

More in detail here.

• The dotnet-version syntax was updated and now it allows to specify the prerelease version without using include-prerelease input. The include-prerelease input was cut out:

      with:
        dotnet-version: '5.0.0-preview.6'

More in detail here.

Apparently GitHub is having problems. I tested on a few other repos and I am seeing 500s there too.

Merging manually for now.
