Apr 1, 2026April 2026 (microsoft/Power-Fx): Delivered targeted formatter reliability and CDP data handling improvements, with two high-impact contributions that collectively improve developer experience and reduce post-deploy issues. Key features delivered include PrettyPrint enhancements that preserve trailing comments after user definitions and within user-defined headers, plus expanded test coverage to ensure idempotence across diverse comment scenarios. Major bugs fixed include improved error handling for CDP responses in GetResult, introducing descriptive exceptions for missing or mistyped 'value' fields and adding regression tests.

Sep 1, 2025September 2025 (2025-09) — Focused on expanding Power-Fx OpenAPI integration by delivering integer-based enum support in the OpenAPI Connector. The work included implementation, targeted tests, and validation resources to ensure reliable parsing as either primitive decimals or option sets based on connector settings. This enhances interoperability with APIs that expose enum values as integers and reduces downstream data handling friction.
