## 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.
