🤖 I have created a release beep boop

0.17.0 (2026-10-26)

⚠ BREAKING CHANGES

• adapter: ValidationAdapter gains a new required method, serialize_response(). Existing custom adapter implementations must add it before upgrading; a thin pass-through to serialize() is sufficient for a backend that never configures response_model. Per this pre-1.0 package's compatibility policy, this ships as a minor release.

Bug Fixes

• adapter: honor AliasChoices precedence when multiple header aliases are present (#563) (62ec67e), closes #562
• adapter: honor custom response backends during preparation and serialization (#553) (6a4e08c)
• adapter: honor validation aliases in query and header normalization (#555) (9bb5fd3)
• adapter: isolate missing-body error locations between requests (#557) (cb3e6d1)
• adapter: return 400 for JSON nested beyond a portable depth limit (#583) (a8856ad)
• ci: stop printing WEBSITE_RUN_FROM_PACKAGE verbatim when it carries a package URL/SAS token (#565) (1bc5b45), closes #564
• diagnose mismatched injected model parameters early (#609) (236f5c7)
• metadata: emit endpoint contracts for supported generic model annotations (#550) (78fb588)
• pipeline: contain unexpected adapter serialization and formatter faults (#556) (7a31529)
• query: normalize singleton values for nullable list fields (#554) (42a1c96)
• return sanitized 400 for oversized JSON integers (#591) (654f502)
• worker: preserve custom http trigger parameter names (#552) (a6c0d2e)

Release PR intentionally left unmerged. AGENTS.md and CONTRIBUTING.md reserve release cutting for the maintainer, and merging this PR creates the tag/publish chain. Open #574 still documents the unrelated Cookbook host gate, #567 the missing exact-wheel runtime-advisory release gate, and #585 has a tested but not-yet-merged fix (#591). No versions, manifest, changelog, or tags were edited; no release dry-run or Azure certification is claimed by this pass.
