Release Notes

Features

  • Add JAEC native inference pipeline — Introduced a native inference pipeline for Joint Acoustic Echo Cancellation (JAEC) under the audio/AEC module.
  • Add FLA-TF-Locoformer and FLA-T-SepReformer separators — Added two new speech separation models (FLA-TF-Locoformer and FLA-T-SepReformer) for 2-speaker 8 kHz audio, including shared attention layers, pipeline registration, test cases, and ONNX export support.
  • Add Agent IDP and MCP/Studio OpenAPI — Added SDK and CLI compatibility shims for agent identity management (key rotation, status, signed token issuance) and new deploy_mcp_server / undeploy_mcp_server methods to MCPApi.

Fixes

  • Resolve OpenEuler build and x86 dependency issues for vLLM Ascend — Added the patch package to build dependencies for both Debian-based and OpenEuler-based Ascend Docker images, and added the PyTorch CPU wheel index to PIP_EXTRA_INDEX_URL to fix dependency resolution on x86 hosts.
  • Unified upload environments — Unified the upload environment variables and added custom README content for uploading AIGC model weights.
  • Fix constants issue — Resolved a constants-related issue in the MCP/Studio delegation logic.

Enhancements

  • Support configurable source installation of mcore-bridge in Ascend Docker image — The Ascend Docker image now supports building mcore-bridge from source with configurable branch/version, improving flexibility for Megatron-based training environments.
  • Update modelscope-hub version — Updated the dependency on modelscope-hub to a newer version, bringing in CLI unification, auth fixes, and endpoint normalization improvements.
  • MCP API consistency — Routed MCP discovery, operational-server listing, and server-detail requests through modelscope-hub for consistent authentication, retry, and error handling; consolidated Studio CLI as a re-export of the hub implementation.
