Hellu!
The 1.19 update is already out on Java. Bedrock is just slightly behind.
The 1.19 update on Java brought with it a lot of fun new content and revamped old content. Examples of new content are new maps that use some newer version mechanics (ex: Warden and dripstone), a wholly revamped version of the Lucky Islands/Lucky Blocks minigame and a new EggWars season. This, alongside the revamped content such as revamped maps (ex: lobby and game maps) and major & minor bug fixes. The update, however, is definitely not limited to this content only.
Bedrock will likely have some different aspects added/changed/fixed as it isn’t the same as Java, but the majority of the content will probably be about the same. You can find out more about the update on the
CubeCraft Notion board.
