Artifactory requires applying SemVer 2.0 rules for Pub repositories, which means you can now use pre-release numbers with dot notation or add metadata to the version, for example: MyApp.3.0.0-build.60, MyApp.1.0+git.52406.
Artifactory serves the requests for downloading packages using SemVer 2.0 rules. For example, if the latest version for a certain package is in a SemVer 2.0 convention, Artifactory will return it to the client. NuGet packages with the SemVer 2.0 convention are served from local, remote, and virtual repositories and for both Pub API v2, and v3 feeds.
