+## [1.23.1](https://github.com/opsmill/infrahub-sdk-python/tree/v1.23.1) - 2026-08-28
+
+### Fixed
+
+- Fixed `client.branch.validate()` and `infrahubctl branch validate`, which raised a `GraphQLError` against every supported Infrahub server because the mutation requested a `messages` field that was removed from `BranchValidate` in Infrahub 1.1.0. ([#1263](https://github.com/opsmill/infrahub-sdk-python/issues/1263))
+- The queries generated by `all()`, `filters()`, `get()` and relationship `fetch()` no longer request `count` on cardinality-many relationships. The SDK never read that value, and Infrahub resolved it with one extra database query per returned node and per relationship, on top of preventing the peer reads of those nodes from being batched into a single query.
