I've noticed in CodePlex, a changeset ID under the Source Control --> History section is shorter than the full changeset Id within the URL when viewing changeset.
How does one easily navigate to a changeset from the shorter ID, which is often quoted when a work item is fixed?
While a change set list (like the Nuget one) does display short SHA1, any commit link you click on is actually the full SHA1:
http://nuget.codeplex.com/SourceControl/changeset/a5557ecdb5b0728945e1ced8e7ae9983d7f3b4bc
So the information about the SHA1 is never lost.
