I've started to work in an existing drupal development project and wanted to do some module updates and found modules with versions like this:

  • Universally Unique IDentifier 7.x-1.0-alpha3+47-dev
  • Taxonomy CSV import/export 7.x-5.10+17-dev

I've never seen this before. According to drupal version number guidelines this is not wanted.

Now, our head developer says they never modified any contributed modules and only took them from drupal.org ... Where do that version numbers come from?

Did I miss something?

  • Last packaged version: 7.x-5.10+17-dev - drupal.org/node/882530 - this is a information added by drupal.org packaging script, do not worry ;) – malcolm Apr 26 '13 at 9:32
  • ah, interesting. but my drupal installation recommends to install 7.x-5.10 instead of 7.x-5.10+17-dev ... ? – Afr Apr 26 '13 at 9:49
  • That's because using dev-versions in general is discouraged. – Letharion Apr 26 '13 at 9:52
  • ok, got it. why is it not called 7.x-5.x-dev anymore? – Afr Apr 26 '13 at 9:55

    @MPD I'm well aware that -dev versions are discouraged, I strongly try to avoid them myself, but I found that to be out of scope for this whole discussion, so I decided to not open up that debate :) – Letharion Apr 26 '13 at 13:28

-dev versions, are regularly built from the latest source code.

To differentiate between todays -dev release, and yesterdays, the number you've indicated counts the number of changes between any two dev releases.

  • so basicly 7.x-5.10+17-dev is a more detailed version number of 7.x-5.x-dev? – Afr Apr 26 '13 at 9:53
  • Yes, it says '17 commits on -dev since the last release', in this case, 5.10. – Letharion Apr 26 '13 at 10:53
  • alright, this is still a bit confusing in the "available updates" page. thanks for clarification! – Afr Apr 26 '13 at 11:02
