API Changes in Structure 9.1

1. Minor Java API Release

There are a few API additions coming with this release. The changes are backwards-compatible, so any code using API 17.x should work fine.

See Structure API Versions for full version information and downloads.

2. Compatible Changes in the Java API

We've added ItemAttributeLoaderBuilder.trailItemSet(Function<I, TrailItemSet>) method to register TrailItemSet by an item value.
