v0.1.92

🚀 Release Highlights — v0.1.92 (2026-06-01)

v0.1.92 is a maintainability release for MassGen's orchestration core, with a new Parallel Web Search MCP example included for research-heavy workflows. The main result: the largest orchestrator surfaces are smaller, more modular, and guarded by characterization tests before deeper behavior changes continue.

🧩 Orchestrator Collaborator Extraction

• orchestrator.py drops from 21,599 to 8,574 lines
• 49 collaborator classes are extracted into massgen/orchestrator_collaborators/
• Existing public methods remain available through thin delegators
• Shared mutable state still lives on the orchestrator, preserving current ownership semantics

🖥️ TUI Display Module Cleanup

• Provider/model display logic moved to _textual_provider_model.py
• Terminal capability probing moved to _textual_terminal_capabilities.py
• Widget debug helpers moved to _textual_widget_debug.py
• Public imports from textual_terminal_display.py stay stable

🔎 Parallel Web Search MCP

• New parallel_search MCP registry entry
• New example config: massgen/configs/tools/web-search/parallel_search_example.yaml
• Supports Parallel's hosted Search MCP server for LLM-optimized web search and URL extraction
• Optional PARALLEL_API_KEY enables higher rate limits

🧪 Characterization Coverage

• massgen/tests/test_orchestrator_characterization.py
• massgen/tests/frontend/test_textual_terminal_display_characterization.py
• Existing integration/unit tests updated for the new collaborator seams
• Refactor roadmap and remaining high-risk follow-up steps documented in docs/dev_notes/orchestrator_refactor_roadmap.md
