Versioning third party package by snapshot date
I maintain release of mavlink package ros.
Upstream developers stopped making releases, it is recommended to use the latest snapshot. So that the original version is stuck at 1.0.9. When I release the update, the release number of the package rises, but it hard to track between ros releases (also it confuse users).
I think it is more convenient to use instead of the original version of the snapshot date in the form of YEAR.MONTH.DAY. But i don't find any related information about releasing snapshots.
