I'm assuming that 1.16.4 is still the active Java version? The main page used to show current version, but I couldn't find it.

The server versions have been updated tonight, with your usual bug fixes and improvements.
Java players, you will now be required to use 1.16.4 to access the survival servers. Yes, Optifine has been updated.
Bedrock players, you will need the latest version on your platform, which should be 1.16.100 as of this writing. If you haven't been auto-updated yet, go check on that!

Yes, that's correct!
The version number isn't listed on the website anymore as our target is always to support whatever the latest one available is. Plus, having version numbers for both Java and Bedrock platforms, as they are different, would make things more difficult to understand at a glance.
