Java Edition - 1.19.4 Pre-release 1

We are now releasing the first pre-release of Minecraft 1.19.4. This pre-release contains a new high contrast accessibility setting, some visual effects updates of the "Create a World" tab, a new execution subcommand, performance improvements at startup and many bug fixes!

For the rest of the 1.19.4 loop, you should mostly see bug fixes. Also, pre-releases don't follow the usual Wednesday release frequency of snapshots, so keep an eye out for the next pre-release.

Successful mining!

CHANGES

• The reflection of the enchantment of items in the inventory has become more noticeable.
• The default value of the Gloss Strength parameter has been reduced to 75%.
