There's not much to say that the title doesn't already say.

You'll find a PR at laminas-db for the upgrade: laminas#309

@tomboe311 yes, and it's greatly appreciated. The issue is that the code had already diverged a great deal by the time we were ready to add SMv4 support. It has now been implemented as well as MySQL, SQLite and Postgres satellite PoC packages in various stages of completion.

None of the code is ready for use yet (very large changes happening every day as code moves to satellite packages). It's coming along very well though.

This has been completed.
