Feb 1, 2025

February 2025 — Pion/webrtc: Implemented VP9 codec support in the IVFWriter and the Save-to-Disk workflow, enabling VP9-encoded media to be saved to disk. Updated the ivfwriter package, save-to-disk sample, and README to reflect VP9 alongside VP8. This work enhances codec flexibility, broadens use cases for storage/export, and aligns with VP9 adoption across WebRTC pipelines.

Jan 1, 2025

January 2025 monthly summary focused on correctness and reliability improvements in the ROCm/flash-attention benchmarks. Delivered a critical fix to the Flash Attention Benchmark: corrected torch dtype mapping for float8_e5m2, aligning with cudnn.data_type. This change improves benchmark accuracy, comparability across environments, and the integrity of performance metrics used by stakeholders. No new features were released this month beyond the fix, but the corrected mapping enhances data interpretation and trust in reported results. Code review and merge completed for the related commit.
