 # Changelog
 
+## [0.1.0-alpha.3](https://github.com/git-ents/facet-git-tree/compare/facet-git-tree-v0.1.0-alpha.1...facet-git-tree-v0.1.0-alpha.3) (2026-10-22)
+
+Note that `v0.1.0-alpha.2` was published accidentally, and was therefore yanked.
+That yanked pre-release did not contain substantive changes.
+
+### ⚠ BREAKING CHANGES
+
+* Remove the migration, schema-pinning, and schema-kind APIs; schema documents no longer carry `kind`, so previously published schema object ids change and documents written in the old shape no longer read
+
+### chore
+
+* Pin release ([cfdbd1c](https://github.com/git-ents/facet-git-tree/commit/cfdbd1c814b88865117ca899b77a89dbe57ebd65))
