For Minecraft: Bedrock Edition 1.19.50

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.

• Removed support for older versions.

4.12.2

Released 15th December 2022.

Fixes

• Folder used for plugins (optionally specified by --plugins) is no longer required to be writable.

Fixes

4.12.5

• 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.

4.12.10

Released 18th January 2023.

Fixes

• Fixed reported server load not including the time spent processing Snooze interrupts between ticks (e.g. incoming network packets).
• Fixed Connection Handler entry in timings report not including time spent receiving packets.

Note about server load & performance

This version will report higher apparent server load than previous versions. The actual performance of the server is unchanged; the previous reported load was inaccurate. These bugs have been present for nearly 5 years (ever since the first introduction of Snooze in 3.0.0).

4.12.11

Released 22nd January 2023.

General

• Code is now tested and analysed using PHP 8.2 in addition to 8.1 and 8.0.

Fixes

• Fixed pthreads 5.0.0 incorrectly being treated as compatible.
• Fixed deprecation errors on PHP 8.2.

Documentation

• Updated documentation in PlayerPreLoginEvent.
