and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [1.20.1-3.6.3] - 2024-03-20
### Fixed
- The patch from last version sometimes crashing, specifically if a file with a missing harvest tier has the old harvest level stat given as a JSON object. [#660]
- Again, this patch will be removed no later than Minecraft 1.21, at which point harvest tiers _must_ be used.
## [1.20.1-3.6.2] - 2024-03-19
### Added
- A temporary compatibility patch to make pre-3.6.0 material JSON files load. This should allow most mods and data packs to function like they did before. A "material has no harvest tier" warning will be logged for each material that has a "guessed" harvest tier.
- This will be removed no later than Minecraft 1.21
## [1.20.1-3.6.1] - 2024-03-17
Please read the changes for 3.6.0 as well!
### Changed
- Added resource ID and pack name to error messages related to loading of materials, parts, and traits. This should help track down mods and data packs that are not updated for 3.6.0.
## [1.20.1-3.6.0] - 2024-03-16
MAJOR BREAKING CHANGE! Please read...
### Changed
- BREAKING: Replaced the harvest level stat with a harvest tier property. This is a **breaking change** for mods and data packs! This change should fix compatibility with mods that add their own `Tier`s for block harvest checks.
- To fix material JSON files, simply add a `harvest_tier` property to the root of the file (same level as `type` and `simple`). The value is a string, which is the name of the Tier, such as `minecraft:iron`.
### Fixed
- Added a proper texture and localized name for Coating Smithing Template
