+Subject: [PATCH] Prevent Pathfinding out of World Border
+
+This prevents Entities from trying to run outside of the World Border
+
+TODO: This doesn't prevent the pathfinder from using blocks outside the world border as nodes. We can fix this
+by adding code to all overrides in:
+    NodeEvaluator:
+    public abstract BlockPathTypes getBlockPathType(BlockGetter world, int x, int y, int z);
+
+to return BLOCKED if it is outside the world border.

+
+Make it so a Treasure Map does not target a structure outside of the
+World Border, where players are not even able to reach.
+
+This also would help the case where a players close to the border, and one
+that is outside happens to be closer, but unreachable, yet another reachable
+one is in border that would of been missed.

+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
+From: Aikar <aikar@aikar.co>
+Date: Sun, 22 Jan 2017 18:07:56 -0500
+Subject: [PATCH] Cap Entity Collisions
+
+Limit a single entity to colliding a max of configurable times per tick.
+This will alleviate issues where living entities are hoarded in 1x1 pens
+
+This is not tied to the maxEntityCramming rule. Cramming will still apply
+just as it does in Vanilla, but entity pushing logic will be capped.
+
+You can set this to 0 to disable collisions.

+Subject: [PATCH] Properly handle async calls to restart the server
+
+The watchdog thread calls the server restart function asynchronously. Prior to
+this change, it attempted to do several non-safe operations from the watchdog
+thread, rather than the main. Specifically, because of a separate upstream change,
+it causes player entities to be ticked asynchronously, among other things.
+
+This is dangerous.
+
+This patch moves the old handling into a synchronous variant, for calls from the
+restart command, and adds separate handling for async calls, such as those from
+the watchdog thread.
+
+When calling from the watchdog thread, we cannot assume the main thread is in a
+tickable state; it may be completely deadlocked. In order to handle this, we mark
+the server as stopping, in order to account for situations where the server should
+complete a tick reasonbly soon, i.e. 99% of cases.
+
+Should the server not enter a state where it is stopping within 10 seconds, We
+will assume that the server has in fact deadlocked and will proceed to force
+kill the server.
+
+This modification does not force restart the server should we actually enter a
+deadlocked state where the server is stopping, whereas this will in most cases
+exit within a reasonable amount of time, to put a fixed limit on a process that
+will have plugins and worlds saving to the disk has a high potential to result
+in corruption/dataloss.

+Subject: [PATCH] Add option to make parrots stay on shoulders despite movement
+
+Makes parrots not fall off whenever the player changes height, or touches water, or gets hit by a passing leaf.
+Instead, switches the behavior so that players have to sneak to make the birds leave.
+
+I suspect Mojang may switch to this behavior before full release.
+
+To be converted into a Paper-API event at some point in the future?

+Subject: [PATCH] Use TerminalConsoleAppender for console improvements
+
+Rewrite console improvements (console colors, tab completion,
+persistent input line, ...) using JLine 3.x and TerminalConsoleAppender.
+
+Also uses the new ANSIComponentSerializer to serialize components when
+logging them via the ComponentLogger, or when sending messages to the
+console, for hex color support.
+
+New features:
+  - Support console colors for Vanilla commands
+  - Add console colors for warnings and errors
+  - Server can now be turned off safely using CTRL + C. JLine catches
+    the signal and the implementation shuts down the server cleanly.
+  - Support console colors and persistent input line when running in
+    IntelliJ IDEA
+
+Other changes:
+  - Server starts 1-2 seconds faster thanks to optimizations in Log4j
+    configuration
