What's Changed

• Add 1.20.5 & 1.20.6 support
• Add Datafixer support to upgrade item NBT to newer versions
• Auto upgrade old ItemStacks when using NBT.itemStackFromNBT and the related methods (it will assume the NBT is 1.20.4 data, otherwise upgrade the NBT before yourself with the Datafixer)
• Fix BlockEntity bug on Mojang mapped servers
• Bump org.apache.maven.plugins:maven-source-plugin from 3.3.0 to 3.3.1 by @dependabot in https://github.com/tr7zw/Item-NBT-API/pull/273
• Bump org.apache.maven.plugins:maven-shade-plugin from 3.5.2 to 3.5.3 by @dependabot in https://github.com/tr7zw/Item-NBT-API/pull/277

Note

Due to Mojang changes to how ItemStacks work at runtime, vanilla NBT won't be visible on loaded ItemStacks in 1.20.5+ anymore. So modifying vanilla data will not work anymore in the same way as for 1.8-1.20.4, and all plugins need to be updated to be aware of that. If in doubt, feel free to ask on Discord.
