 ## [Unreleased]
 
 
+## [0.3.0] - 2026-06-29
+
+### Changed
+
+- Bump the `hotdata-framework` floor to `>=0.5.0` and the `hotdata` SDK to `0.5.0`. Framework 0.5.0 is backward compatible (additive-only: an optional `format` field on `LoadManagedTableRequest` and an optional `format` parameter on `ResultsApi.get_result`), so no source changes were required; the full test suite passes.
