I think for these specific tags it might be better to come up with an agreed upon format rather than let everyone come up with it on the fly. Some quick examples being
I will try to form an answer that we could use in the help page...
Suggested version tags
For mysql and compatible sql servers like mariaDB or Percona Server - mysql-5.0 - mysql-5.1 - ...
For Apache - apache-2.2 - apache-2.4
For PHP - php-5.3 - php-5.4 - ...
and so on... a little bit pointless to write this down ;-)
the better question is should this be enforced or should synonyms be used?
I would go with something like:
- joomla2.5 (as a synonym for joomla1.6, joomla1.7)
- joomla3.x (as a synonym for joomla3.0, joomla3.1, joomla3.2)
- framework1.x (as a synonym for framework1.0, framework1.1 etc.)
Using J1.5 and J15 on the forum. Suggest to use FW1 for Framework, would have preferred F1 but that is easily confused with function keys. Suggest to use no - or . in the numbers. Not sure there needs to be more than: J25, J3 and J4 for the CMS. Can't say anything about framework or with the future packages. Not enough information available on that.
