Important release cycle change
Starting 1.20.5, ViaVersion and ViaBackwards will only be released a day or so *after* a Minecraft update unless the protocol changes of the update were trivial. If you want early-access, usually days or even weeks before the final release, you can subscribe to either:
- GitHub Sponsors (preferred option. Use the `/verify` command on this Discord after), or alternatively
- Patreon (see the highest tier and make sure to link Patreon to your Discord account under Settings->Connections)
This also includes access to a private repository with the code, which will be pushed to the public repository after the given delay on a Minecraft update.

At the same time however, bug fix patches will be released more regularly, always immediately public, and more of the low-priority issues will be tackled.

Due to the insane pace Mojang has been adding more and more complex technical features since 1.19/1.20, updating ViaVersion and making sure it works well enough has become a lot more time-consuming. Without some extra incentive, I can't really justify putting increasing amounts of free time into these updates, no matter how much I enjoy doing them.

Changes
Requires ViaVersion 4.9.3

• Added sanity checks to item reading across all versions
• Fixed various issues in 1.20.3->1.20.2 issues, including component conversion
• Fixed 1.20.2->1.20 tag handling
• Fixed 1.17->1.16 map data reading
• Fixed writable book handling in 1.16->1.15
• Fixed chunk loading game state handling in 1.20.3->1.20.2 (by FlorianMichael)
• Fixed 1.13.1->1.13 item handling (by camdencove)

Note: Via* on BungeeCord does not work properly at the moment, we recommend using our plugins either on the backend servers or on Velocity instead.

1.19.4 server support - Requires ViaVersion 4.6.0

• Improved mapping data loading/startup loading times
  • Custom mapping files have been broken with this, see https://github.com/ViaVersion/ViaBackwards/wiki for more info
  • A `custom_model_data` field can now be defined in item mappings
• Fixed item desyncs when dropping items on 1.17+ servers as 1.13 clients or lower (Paper only)
• Fixed an item mapping issue with goat horns for <1.13 clients (thanks to LoboMetalurgico)
• Fixed an error due to new 1.19 poses
• Fixed comparator rotations in 1.13->1.12
• Fixed handling of bad shot item tags in 1.16->1.15

• Added basic support for 1.19.0 clients on 1.19.1 servers. While it works, some inconveniences will be visible (such as 1.19 items/mobs being mapped to 1.18 types), since the protocol path for this is 1.19.1->1.18.2->1.19 (the same way that 1.19.0 server support isn't as direct as it was in ViaBackwards 4.3.1)
• Handle message formats for outgoing /msg and /teammsg messages

1.19.1 server support - Requires ViaVersion 4.4.0

Requires ViaVersion 4.2.0

• 1.18.2 server support
• Updated Sponge module to Sponge API v8

• Fixed some advancement translatable messages
• Made the custom height warning a warning instead of an error, only printing it once
• Removed visible "Wither skeleton" display name for wither skeletons in 1.11->1.10

Requires ViaVersion 4.0.1

• Added 1.17.1 server support
• Fixed 1.17->1.16 ping packet sending (by SuspiciousActivity)

• Fixed some 1.17->1.16 and 1.16->1.15 particles
• Fixed 1.15->1.14 immediate respawn gamerule
• Fixed entities becoming invisible after you die with a <=1.12 client on a 1.16+ server
• Fixed issues with plugins sending bad metadata packets
• Fixed issues with custom world height

Consider donating! If you encounter any issues, you can get help on our Discord.

• Added 1.17 server support
  • WARNING: Setting custom world height is NOT supported and will lead to problems with older clients joining. While we took effort to at least make it work with a changed min_y world value, both min_y and and changed height are not and will (most likely) never be fully supported.
  • Old clients will simply not see and not be able to interact with any blocks under y=0 and above y=255.

• Chat component transformation has been moved from Bungee Chat to the more reliable/modern adventure project to fix multiple issues in that regard
• Made 1.11->1.10 and 1.10->1.9 sounds configurable
• Fixed plugins setting player skins (sending respawn packets in the same dimension) in 1.16->1.15 (by myles)
• Fixed colored inventory titles in 1.13.1->1.13 (by MrMicky)
• Fixed some mushroom blocks becoming invisible in 1.13->1.12 (by MrMicky)
• Fixed (some) tab completion of commands without permission in 1.13->1.12 (by MrMicky)
• Fixed a handful of tab completion parsers in 1.13-1.15 clients (by RK-01)
• Fixed wolf health tail positions in 1.15->1.14 (by RK-01)
• Fixed various missing sounds and sound warnings in legacy versions
• Fixed lightning bolts in 1.16->1.15
• Fixed errors on legacy server startup with late-bind enabled
• Fixed < 1.12 clients being disconnected when receiving items with long array nbt tags
