Introducing a semantic changelog XML notation

Greetings, I recently did my first contribution to the phpdocs, it was a missing changelog entry for mb_convert_case(). For the first time I saw the syntax of the XML files and I had the immediate feeling a semantic <changelog> XML construct is missing. Given the importance of the changelog (as full time PHP developer I consult the "Changelog" section of the manual pages A LOT) I believe it deserves its own XML tag instead of using <informaltable>. I was thinking about something like (a very random idea, not thought through yet): <changelog> <row> <version>7.3.0</version> <entry>Changed this and that.</entry> </row> </changelog> Do you think this kind of change would be accepted? Has this been discussed before? It would be quite some work to introduce the new markup and create a migration script for the existing documentation, so I'm looking for preliminary feedback before venturing into this. Thank you for your attention. GG.
