+## [2.1.1 — Public Review] — July 2026
+
+Editorial redaction release. Removes novelty-claim framing from the specification text: the `(Novel)` section-heading tags on §§3.2, 3.4, 3.5, 3.6, 3.7, 3.8, 3.17, and 3.18, the associated `**Novel claim**` statements, and internal drafting annotations. **No normative change** — every normative requirement, definition, mechanism, and conformance obligation is identical to 2.1.0; an implementation conformant to the 2.1.0 public-review text remains conformant against 2.1.1 at the same level. Version identity advances with the live normative surface per this changelog's provenance convention.

 ## [2.1.0 — Public Review] — July 2026
 
 Second public-review release of the XSI-AIMS specification. This release advances the current normative surface from 2.0; changes are additive and single-sourcing only — no 2.0 normative obligation is weakened or removed, and an implementation conformant to the 2.0 public-review text remains conformant against 2.1.0 at the same level. The specification remains a public-review draft; feedback gathered during the review window may produce further additive revisions before the release is finalized.
