## 4.29.0
**`(feat):`** Add AI changelog rollup for multi-chunk diff analysis. When large diffs
are split into multiple chunks, the resulting changelog entries are now
consolidated via a dedicated AI call that deduplicates repetitive bullets,
groups changes under Keep a Changelog headers (Breaking Changes, Added,
Changed, Fixed), and produces a structured PR description with
Before/After code fences for breaking changes. Also adds a
`version_bump_reason` field to AI analysis responses, providing an
explicit one-sentence justification for why MAJOR/MINOR/PATCH was chosen.


## 4.28.0
**`(feat):`** Add `coerce-consts-to` setting for controlling how OpenAPI/AsyncAPI
`const` values are represented. Set to `literals` to convert them directly
