Wonder why they renamed it from Claude <number> <type> (e.g. Claude 3.7 Sonnet) to Claude <type> <number> (Claude Opus 4).

I guess because they haven't been releasing all three models of the same version in a while now. We've only had Sonnet updates, so the version first didn't make sense if we had 3.5 and 3.7 Sonnet but none of the others.
