+Subject: [PATCH] API to get a BlockState without a snapshot
+
+This allows you to get a BlockState without creating a snapshot, operating
+on the real tile entity.
+
+This is useful for where performance is needed
+
+also Avoid NPE during CraftBlockEntityState load if could not get TE
+
+If Tile Entity was null, correct Sign to return empty lines instead of null

+Subject: [PATCH] Actually unload POI data

+While it's not likely for a poi data leak to be meaningful,
+sometimes it is.
+
+This patch also prevents the saving/unloading of POI data when
+world saving is disabled.

+Subject: [PATCH] Add APIs to replace OfflinePlayer#getLastPlayed
+
+Currently OfflinePlayer#getLastPlayed could more accurately be described
+as "OfflinePlayer#getLastTimeTheirDataWasSaved".
+
+The API doc says it should return the last time the server "witnessed"
+the player, whilst also saying it should return the last time they
+logged in. The current implementation does neither.
+
+Given this interesting contradiction in the API documentation and the
+current defacto implementation, I've elected to deprecate (with no
+intent to remove) and replace it with two new methods, clearly named and
+documented as to their purpose.

+Subject: [PATCH] Add ArmorStand Item Meta
+
+This is adds basic item meta for armor stands. It does not add all
+possible metadata however.
+
+There are armor, hand, and equipment types, as well as position data
+that can also be added here. This initial addition should serve a
+starting point for future additions in this area.
+
+Fixes GH-559

+Subject: [PATCH] Add Early Warning Feature to WatchDog

+Detect when the server has been hung for a long duration, and start printing
+thread dumps at an interval until the point of crash.
+
+This will help diagnose what was going on in that time before the crash.

+Subject: [PATCH] Add PlayerConnectionCloseEvent
+
+This event is invoked when a player has disconnected. It is guaranteed that,
+if the server is in online-mode, that the provided uuid and username have been
+validated.
+
+The event is invoked for players who have not yet logged into the world, whereas
+PlayerQuitEvent is only invoked on players who have logged into the world.
+
+The event is invoked for players who have already logged into the world,
+although whether or not the player exists in the world at the time of
+firing is undefined. (That is, whether the plugin can retrieve a Player object
+using the event parameters is undefined). However, it is guaranteed that this
+event is invoked AFTER PlayerQuitEvent, if the player has already logged into
+the world.
+
+This event is guaranteed to never fire unless AsyncPlayerPreLoginEvent has
+been called beforehand, and this event may not be called in parallel with
+AsyncPlayerPreLoginEvent for the same connection.
+
+Cancelling the AsyncPlayerPreLoginEvent guarantees the corresponding
+PlayerConnectionCloseEvent is never called.
+
+The event may be invoked asynchronously or synchronously. As it stands,
+it is never invoked asynchronously. However, plugins should check
+Event#isAsynchronous to be future-proof.
+
+On purpose, the deprecated PlayerPreLoginEvent event is left out of the
+API spec for this event. Plugins should not be using that event, and
+how PlayerPreLoginEvent interacts with PlayerConnectionCloseEvent
+is undefined.

+Subject: [PATCH] Add Plugin Tickets to API Chunk Methods
+
+Like previous versions, plugins loading chunks kept them loaded until
+they garbage collected to avoid constant spamming of chunk loads
+
+This adds tickets to a few more places so that they can be unloaded.
+
+Additionally, this drops their ticket level to BORDER so they wont be ticking
+so they will just sit inactive instead.
+
+Using .loadChunk to keep a chunk ticking was a horrible idea for upstream
+when we have TWO methods that are able to do that already in the API.
+
+Also reduce their collection count down to a maximum of 1 second. Barely
+anyone knows what chunk-gc is in bukkit.yml as its less relevant now, and
+since this wasn't spigot behavior, this is safe to mostly ignore (unless someone
+wants it to collect even faster, they can restore that setting back to 1 instead of 20+)
+
+Not adding it to .getType() though to keep behavior consistent with vanilla for performance reasons.

+Subject: [PATCH] Add Velocity IP Forwarding Support
+
+While Velocity supports BungeeCord-style IP forwarding, it is not secure. Users
+have a lot of problems setting up firewalls or setting up plugins like IPWhitelist.
+Further, the BungeeCord IP forwarding protocol still retains essentially its original
+form, when there is brand new support for custom login plugin messages in 1.13.
+
+Velocity's modern IP forwarding uses an HMAC-SHA256 code to ensure authenticity
+of messages, is packed into a binary format that is smaller than BungeeCord's
+forwarding, and is integrated into the Minecraft login process by using the 1.13
+login plugin message packet.

+Subject: [PATCH] Add Wandering Trader spawn rate config options
+
+Adds config options for modifying the spawn rates of Wandering Traders.
+These values are all easy to understand and configure after a quick read of this
+page on the Minecraft wiki: https://minecraft.gamepedia.com/Wandering_Trader#Spawning
+Usages of the vanilla WanderingTraderSpawnDelay and WanderingTraderSpawnChance values
+in IWorldServerData are removed as they were only used in certain places, with hardcoded
+values used in other places.

+Subject: [PATCH] Add debug for sync chunk loads
+
+This patch adds a tool to find calls to getChunkAt which would load
+chunks, however it must be enabled by setting the startup flag
+-Dpaper.debug-sync-loads=true
+
+- To get a debug log for sync loads, the command is
+  /paper syncloadinfo
+- To clear clear the currently stored sync load info, use
+  /paper syncloadinfo clear
