Repro Steps & Context

We call
nuget.exe pack Package.nuspec -NonInteractive -Properties "version=2.0.0;prerelease=-preview"

Our Nuspec file looks like (no project sdk yet)

<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">
  <metadata>
    <id>Package</id>    
    <version>$version$$prerelease$</version>
...
    <dependencies>
      <dependency id="Other.Package" version="[$version$$prerelease$]" />
    </dependencies>
  </metadata>
  <files>
...
  </files>
</package>

With the older nuget.exe a file package.2.0.0-preview.nupkg is created with the metadata version 2.0.0-preview

Now a file package.2.0.0.nupkg is created with the metadata version 2.0.0

Remarkable is that the dependencies still have the prerelease information in the versionspec, only the package version is affected.

It is really critical, because now all of our preview nugets are not flagged as preview and all nuget updates will automatically choose the latest version which is usually a preview.
