+# Changelog
+
+## 1.0.0 (2026-08-25)
+
+
+### Additions
+
+* bootstrap the canonical Musher specification repository ([e3b8ea5](https://github.com/musher-dev/spec/commit/e3b8ea5e574ef63d54ec75c7c8527301401f01e7))
+* execute the semantic phase, and close the conformance debt behind issue [#9](https://github.com/musher-dev/spec/issues/9) ([#25](https://github.com/musher-dev/spec/issues/25)) ([5be1e0a](https://github.com/musher-dev/spec/commit/5be1e0a903d918cef049fc873538fd31773211e4))
+* fill the spec.md TODOs from implemented behaviour, and settle cycle detection ([#13](https://github.com/musher-dev/spec/issues/13)) ([be77e19](https://github.com/musher-dev/spec/commit/be77e192233e3c15ea524a7485f4af5228cfb332))
+* **listing:** constrain the description Markdown subset, and state the vocabulary governance rule ([#39](https://github.com/musher-dev/spec/issues/39)) ([cf129c4](https://github.com/musher-dev/spec/commit/cf129c45b0b501ea1c8a6b9b764b30e35d268ca2))
+* **listing:** define how a description image resolves after ingest ([#47](https://github.com/musher-dev/spec/issues/47)) ([9c8238a](https://github.com/musher-dev/spec/commit/9c8238a3a331df24e1b88418180c9c6fd19fede5))
+* **listing:** define what metadata.version agrees with in a COMPONENT item ([#37](https://github.com/musher-dev/spec/issues/37)) ([3031344](https://github.com/musher-dev/spec/commit/303134490aadb6d5feb2079b3beae1e97a179d60)), closes [#21](https://github.com/musher-dev/spec/issues/21)
+* **repo:** rebuild exact-version schemas from tags, and harden the specification for 1.0.0 ([#42](https://github.com/musher-dev/spec/issues/42)) ([e840e6d](https://github.com/musher-dev/spec/commit/e840e6dab459ffaa2cfcf977b04f79c7a02734e9))
+
+
+### Corrections
+
+* **listing:** case-fold the scalar URL scheme pattern so §4.1's two placements agree ([#45](https://github.com/musher-dev/spec/issues/45)) ([e5a3f85](https://github.com/musher-dev/spec/commit/e5a3f85d0f500842185c0ccbcf60d6e8fd923907)), closes [#43](https://github.com/musher-dev/spec/issues/43)
+
+
+### Specification prose
+
+* **component:** specify the behaviour when a document uses a field from a newer schema release ([#26](https://github.com/musher-dev/spec/issues/26)) ([0ce4997](https://github.com/musher-dev/spec/commit/0ce4997f968549170adc7c288819d390421ed96f))
