| pas-ha[m] | lajoskatona: yes. the template version defines what functions and other features are available in the template and their behavior. So a template with a given version should work the same on any openstack release that supports this version. AFAIK heat has not yet ever removed a supported template version, and e.g. we are routinely using 'pike' version templates to deploy on Yoga and Antelope. | 09:28 |

| lajoskatona | pas-ha[m]: Hi, thanks, so I can assume that old template versions will be supported, let's say in Caracal, even if it is not written | 09:32 |
| pas-ha[m] | lajoskatona: yes. there's also an API for that, CLI command is `openstack orchestration template version list` that shows you the template versions supported by this given installation of Heat | 09:48 |
| pas-ha[m] | I kind of suspect where the confusion comes from.. Please understand that template versions are not bumped with every openstack release. A new template version is created only if there's a new functionality to be had - a new template function, some big change in behavior etc. | 09:51 |
| pas-ha[m] | Current latest template version is 'wallaby', because that was the last time a big enough change that warranted a new template version was made. | 09:51 |
| lajoskatona | pas-ha[m]: thanks for the confirmation, that was my understanding from the doc, but now it is clear what I can expect | 09:52 |
| pas-ha[m] | in some sense template versions are like api microversions :-) | 09:56 |
| lajoskatona | pas-ha[m]: that was also in my mind as nova microversion for example also not officially but there since the beginning (at least I don't know about such doc that states they will be there and no deprecation will happen) | 10:07 |
