Some services which extend GitHub Enterprise require a sufficiently recent version. But as a standard user of GH:E, how can I determine, without bugging my admin, which version my company has installed?
I was searching for the same information for our github enterprise version. In the page source I found the following:
<a href="/">
<span class="octicon-mark-github" title="GitHub Enterprise Version 11.10.xxx"></span>
</a>
This is the GitHub Octocat logo in the footer of GitHub Enterprise - just hover over it to get a tooltip with the version number.
