 - Fixed incorrect fire ticks when being set on fire by lava (8 seconds in Bedrock instead of 15).
 - `Entity->attack()` now cancels damage from `FIRE` and `FIRE_TICK` damage causes if the entity is fireproof.
 - Fixed inventory windows getting force-closed when the client attempts to use an enchanting table or anvil.
+
+# 4.6.2
+Released 6th August 2022.
+
+## Core
+- Improved server-side performance of `PlayerAuthInputPacket` handler.
+- Improved client-side performance of `FloatingTextParticle` by using an invisible falling block entity. This offered a roughly 5x performance improvement over using tiny invisible players in local testing.
+
+## Fixes
+- Fixed assert failures and debug spam on debug Minecraft clients related to abilities in `AddPlayerPacket`.
+- Fixed crash in `ReversePriorityQueue` on PHP 8.1 by adding `#[ReturnTypeWillChange]` attribute.

+**For Minecraft: Bedrock Edition 1.19.20**
+
+### Note about API versions
+Plugins which don't touch the protocol and compatible with any previous 4.x.y version will also run on these releases and do not need API bumps.
+Plugin developers should **only** update their required API to this version if you need the changes in this build.
+
+**WARNING: If your plugin uses the protocol, you're not shielded by API change constraints.** You should consider using the `mcpe-protocol` directive in `plugin.yml` as a constraint if you do.
+
+# 4.7.0
+Released 9th August 2022.
+
+## General
+- Added support for Minecraft: Bedrock Edition 1.19.20.
+- Removed support for older versions.
