+Subject: [PATCH] Paper Metrics
+
+Removes Spigot's mcstats metrics in favor of a system using bStats
+
+To disable for privacy or other reasons go to the bStats folder in your plugins folder
+and edit the config.yml file present there.
+
+Please keep in mind the data collected is anonymous and collection should have no
+tangible effect on server performance. The data is used to allow the authors of
+PaperMC to track version and platform usage so that we can make better management
+decisions on behalf of the project.

+Subject: [PATCH] Further improve server tick loop
+
+Improves how the catchup buffer is handled, allowing it to roll both ways
+increasing the effeciency of the thread sleep so it only will sleep once.
+
+Also increases the buffer of the catchup to ensure server stays at 20 TPS unless extreme conditions
+
+Previous implementation did not calculate TPS correctly.
+Switch to a realistic rolling average and factor in std deviation as an extra reporting variable

+
+The process of determining an entity's exposure from explosions can be
+expensive when there are hundreds or more entities in range.
+
+This patch adds a per-tick cache that is used for storing and retrieving
+an entity's exposure during an explosion.

+These commands would then process EXPECTING to be on the main thread, leaving to
+very hard to trace concurrency issues.

+big slowdown in execution but throwing an exception at same time to raise awareness
+that it is happening so that plugin authors can fix their code to stop executing commands async.

+Subject: [PATCH] Configurable inter-world teleportation safety
+
+People are able to abuse the way Bukkit handles teleportation across worlds since it provides a built in teleportation
+safety check.
+
+To abuse the safety check, players are required to get into a location deemed unsafe by Bukkit e.g. be within a chest
+or door block. While they are in this block, they accept a teleport request from a player within a different world. Once
+the player teleports, Minecraft will recursively search upwards for a safe location, this could eventually land within a
+player's skybase.
+
+Example setup to perform the glitch: http://puu.sh/ng3PC/cf072dcbdb.png
+The wanted destination was on top of the emerald block however the player ended on top of the diamond block.
+This only is the case if the player is teleporting between worlds.

+
+Entities collision is checking for scoreboards setting.
+This is very heavy to do map lookups for every collision to check
+this setting.
+
+So avoid looking up scoreboards and short circuit to the "not on a team"
+logic which is most likely to be true.

+Subject: [PATCH] Default loading permissions.yml before plugins
+
+Under previous behavior, plugins were not able to check if a player had a permission
+if it was defined in permissions.yml. there is no clean way for a plugin to fix that either.
+
+This will change the order so that by default, permissions.yml loads BEFORE plugins instead of after.
+
+This gives plugins expected permission checks.
+
+It also helps improve the expected logic, as servers should set the initial defaults, and then let plugins
+modify that. Under the previous logic, plugins were unable (cleanly) override permissions.yml.
+
+A config option has been added for those who depend on the previous behavior, but I don't expect that.

+Subject: [PATCH] Handle Item Meta Inconsistencies
+
+First, Enchantment order would blow away seeing 2 items as the same,
+however the Client forces enchantment list in a certain order, as well
+as does the /enchant command. Anvils can insert it into forced order,
+causing 2 same items to be considered different.
+
+This change makes unhandled NBT Tags and Enchantments use a sorted tree map,
+so they will always be in a consistent order.
+
+Additionally, the old enchantment API was never updated when ItemMeta
+was added, resulting in 2 different ways to modify an items enchantments.
+
+For consistency, the old API methods now forward to use the
+ItemMeta API equivalents, and should deprecate the old API's.

+Subject: [PATCH] Configurable Chunk Inhabited Time
+
+Vanilla stores how long a chunk has been active on a server, and dynamically scales some
+aspects of vanilla gameplay to this factor.
+
+For people who want all chunks to be treated equally, you can chose a fixed value.
+
+This allows to fine-tune vanilla gameplay.

+Subject: [PATCH] Sanitise RegionFileCache and make configurable.
+
+RegionFileCache prior to this patch would close every single open region
+file upon reaching a size of 256.
+This patch modifies that behaviour so it closes the the least recently
+used RegionFile.
+The implementation uses a LinkedHashMap as an LRU cache (modified from HashMap).
+The maximum size of the RegionFileCache is also made configurable.

+Subject: [PATCH] Option to use vanilla per-world scoreboard coloring on names
+
+This change is basically a bandaid to fix CB's complete and utter lack
+of support for vanilla scoreboard name modifications.
+
+In the future, finding a way to merge the vanilla expectations in with
+bukkit's concept of a display name would be preferable. There was a PR
+for this on CB at one point but I can't find it. We may need to do this
+ourselves at some point in the future.

+Subject: [PATCH] Improve Maps (in item frames) performance and bug fixes
+
+Maps used a modified version of rendering to support plugin controlled
+imaging on maps. The Craft Map Renderer is much slower than Vanilla,
+causing maps in item frames to cause a noticeable hit on server performance.
+
+This updates the map system to not use the Craft system if we detect that no
+custom renderers are in use, defaulting to the much simpler Vanilla system.
+
+Additionally, numerous issues to player position tracking on maps has been fixed.

+Subject: [PATCH] LootTable API & Replenishable Lootables Feature
+
+Provides an API to control the loot table for an object.
+Also provides a feature that any Lootable Inventory (Chests in Structures)
+can automatically replenish after a given time.
+
+This feature is good for long term worlds so that newer players
+do not suffer with "Every chest has been looted"

+Subject: [PATCH] Fix Old Sign Conversion
+
+1) Sign loading code was trying to parse the JSON before the check for oldSign.
+   That code could then skip the old sign converting code if it triggers a JSON parse exception.
+2) New Mojang Schematic system has Tile Entities in the new converted format, but missing the Bukkit.isConverted flag
+   This causes Igloos and such to render broken signs. We fix this by ignoring sign conversion for Defined Structures
