AFAIK the historical progression of the standard location of an appstream data file for a regular desktop app is as follows:

  1. /usr/share/appdata/<ID>.appdata.xml
  2. /usr/share/metainfo/<ID>.appdata.xml
  3. /usr/share/metainfo/<ID>.metainfo.xml (current spec)

What was the first appstream version that supported the current location (3)?

I'm asking to determine which old distros support it and when it's safe for upstream projects to change this in their source trees.
