+Breaking changes:
+
+- Stricter f32 / f64 to decimal conversions. Only finite floats that are in the
+  range that can be presented are converted.
+- Updated error messages.
+- Bumped the MSRV to Rust 1.83.
+- Drop `arrow<53` support.
+- Drop `arrow2` support.
+- Updated the `marrow` dependency to `0.3.0-rc.1`.
+
+Bug fixes:
+
+- Fixed variable-shape tensor extension metadata generation when metadata
+  options are present.
+- Improved validation for decimal parsing and formatting and the implementation
+  of Arrow view arrays to avoid Rust APIs that may panic in favor of error
+  producing APIs.
