 ## Dependencies
 - Updated BedrockProtocol to [17.1.0](https://github.com/pmmp/BedrockProtocol/releases/tag/17.1.0+bedrock-1.19.50). This adds some missing `LevelSoundEvent` constants and fixes the values for `ContainerUIIds`.
+
+# 4.12.3
+Released 28th December 2022.
+
+## Fixes
+- Fixed unauthenticated connections taking up player count slots, preventing players from joining.
+- Fixed a possible crash in `World->tickChunk()` when plugins unload chunks during some events.
+- `/gamemode` will now report a failure to change game mode if the player is already in the requested game mode.
+
+# 4.12.4
+Released 3rd January 2023.
+
+## Fixes
+- Added workarounds for an active exploit being used to deny service to servers.
+
+# 4.12.5
+Released 6th January 2023.
+
+## Fixes
+- Removed a workaround for an old client bug in custom form responses. The code contained a denial-of-service vulnerability.
+
+# 4.12.6
+Released 7th January 2023.
+
+## Changes
+- Added a new security measure to `NetworkSession` to detect and ban players who flood the server with packets.
+
+# 4.12.7
+Released 8th January 2023.
+
+## Fixes
+- Fixed players getting kicked when the server lags for too long.
+- Fixed players getting kicked when a debugging session is active and a breakpoint is hit.
+
+# 4.12.8
+Released 9th January 2023.
+
+## Fixes
+- Fixed players getting kicked during PvP.
+- Fixed players randomly getting kicked on Windows (improper rate limit handling wrt. 15ms timer resolution).
+
+# 4.12.9
+Released 16th January 2023.
+
+## Improvements
+### Timings
+- Added new timers:
+  - `Server Mid-Tick Processing` - time spent processing Snooze interrupts between ticks (e.g. incoming network packets)
+  - `Server Tick Update Cycle` - time spent processing regular per-tick updates (e.g. entity movement, world updates, etc.) (`Server->tick()`)
+- `Full Server Tick` timer now counts the total of `Server Mid-Tick Processing` and `Server Tick Update Cycle`, which generates more accurate performance metrics.
+  - Previously, this timer only counted the time spent during regular per-tick updates, and the time recorded by `Server Mid-Tick Processing` was not included in the report at all.
+
+## Fixes
+- Fixed blocks such as pressure plates being able to be placed without the correct supporting blocks if the clicked block was solid.
+- Pressure plates now self-destruct when the block below them is removed.
+- Fixed being unable to place blocks by clicking on the side of a bell (when the click doesn't result in ringing the bell).
+- Fixed various rotation-aware blocks (e.g. stairs) behaving incorrectly when placed by clicking on the side of a replaceable block (e.g. tall grass).
+- Fixed banners being able to be placed on top of blocks such as skulls.
+- Fixed server-side collision boxes of walls and glass (which should connect, but didn't). Note that wall connections still don't show client side - this just fixes the collision boxes.
+- Fixed `PlayerInteractEvent` with `LEFT_CLICK` sometimes firing before `BlockBreakEvent` when breaking blocks.
+
+## Other changes
+- Increased packet batch budget for player sessions.

Dylan K. Taylor	a79be994de	World: fixed block placement when clicking on replaceable blocks in vanilla, it appears to behave as if the player always clicked on the up face if a block was replaced. In PM, we were still using the original face, which caused bugs when, for example, placing a button next to a wall by clicking on the side of tallgrass. The button would replace the tallgrass, but stick to the wall, instead of placing itself on the ground like vanilla expects. This may appear unusual to anyone who also happens to implement canBePlacedAt(), since the facing behaviour will be different. However, this behaviour appears to match vanilla, and even slabs (which I feared might break because of this change) work perfectly. In the future, it may be desirable to pass some other value here, such as null, to indicate that the clicked block is being replaced. However, that's a BC break and therefore outside of the scope of a stable bug fix.	2023-01-12 21:11:48 +00:00
