# Changelog

## 0.5.0 - 2026-09-29

### Added

- Parsed `JWK` and `JwkSet` values now own their key material and metadata
  allowing copies can be safely passed to worker threads without sharing
  mutable JSON state.
- Added `%jwk` serialization, which produces an independent `JsonNode` and
  retains extension members.
- The unit-test task now runs under threaded ARC and ORC memory management, with
  coverage for copied key caches used concurrently by workers.

### Changed

- `initJwk` now snapshots its input JSON. Mutating the source `JsonNode` after
  parsing no longer changes the resulting key.
- `jwk["member"]` still returns `Option[JsonNode]`, but the node is now a fresh
  copy. Mutating it no longer changes the key; construct a new key with
  `initJwk` to make a modification.
