* Updated Upstream (Bukkit/CraftBukkit) Upstream has released updates that appears to apply and compile correctly. This update has not been tested by PaperMC and as with ANY update, please do your own testing Bukkit Changes: 45690fe9 SPIGOT-5047: Correct slot types for 1.14 inventories CraftBukkit Changes: 4090d01f SPIGOT-5047: Correct slot types for 1.14 inventories e8c08362 SPIGOT-5046: World#getLoadedChunks returning inaccessible cached chunks. d445af3b SPIGOT-5067: Add item meta for 1.14 spawn eggs * Bring Chunk load checks in-line with spigot As of the last upstream merge spigot now checks ticket level status when returning loaded chunks for a world from api. Now our checks will respect that decision. * Fix spawn ticket levels Vanilla would keep the inner chunks of spawn available for ticking, however my changes made all chunks non-ticking. Resolve by changing ticket levels for spawn chunks inside the border to respect this behavior. * Make World#getChunkIfLoadedImmediately return only entity ticking chunks Mojang appears to be using chunks with level > 33 (non-ticking chunks) as cached chunks and not actually loaded chunks. * Bring all loaded checks in line with spigot Loaded chunks must be at least border chunks, or level <= 33

Subject: [PATCH] Strip private area unicode characters from signs
|
|
|
|
It is not immediately clear how these characters ended up on signs in
|
|
previous versions. It is clear, however, that they now render as empty
|
|
unicode boxes in 1.13, whereas previously they rendered as invisible
|
|
characters.
|
|
|
|
When these signs are loaded in versions after this commit, these
|
|
characters from the private use area of the Unicode block will be
|
|
stripped. The sign will then be marked to ensure this conversion only
|
|
runs once.
|
|
|
|
There is a flag -DPaper.keepInvalidUnicode=true that can be used if you
|
|
do not want us to strip these characters from your signs, though I can
|
|
think of no reason to use it.
|
|
|
|
Fixes GH-1571
