OpenCollab 0.5.0

OpenCollab 0.5.0 expands the framework's provider support, strengthens runtime integrity, and adds a compact reference implementation of a structured multi-agent organization.

Highlights

• Native OpenAI Responses API transport with typed streaming, encrypted reasoning replay, exact function-call identity, structured-output projection, provider usage accounting, and a shared provider-failure retry budget.
• DeepSeek V4 Flash aliases use the full 1,048,576-token context window and support the max reasoning effort.
• Anthropic manual and adaptive thinking settings now preserve provider-compatible sampling, tool selection, and signed thinking continuity.
• Scheduler and session boundaries preserve terminal failures, ownership, budgets, deadlines, and snapshot isolation.
• Mini Edict demonstrates a tested Three Departments and Six Ministries workflow with a compact team configuration and hard-gated workflow.

Reliability

• Structured-output corrective retries are capped at 60 seconds while respecting shorter caller deadlines.
• Responses reasoning and function-call state remain continuous across stateless tool rounds.
• Incomplete streams, malformed call identities, stale restored turns, unbounded teammate delivery, and incomplete reviewer outcomes are rejected instead of being reported as successful work.
• Workflow and team runs can independently configure task concurrency and cleanup timeouts.

Release integrity

The maintainer explicitly authorized this release to use an unsigned annotated tag because no signing key was registered for the publishing account. The repository had no tag protection rules at publication time. The published v0.5.0 tag is immutable by maintainer decision and resolves to commit 963585611ad2a1d0c1fc7f4ba0043af5a3d860bb.
