Context
This story is part of the feature that will change the MediaWiki localisation format from executable PHP code to JSON. The full change is described in RFC Localisation format.
This is a complementary approach to Localisation Update.
Narrative
As a MediaWiki administrator, I can receive localisation updates with point releases of MediaWiki, so that I can benefit from localisation updates with very little effort.
Acceptance Criteria
- Ensure branch support works again (2 versions back) in translatewiki.net
- Ensure MediaWiki core branch localisation can be exported using Translate update to versions back (1.20/1.21).
