Mosoo v0.2.3 (Alpha)

Mosoo v0.2.3 is an Alpha patch release focused on durable Task Agent Thread continuation, Driver protocol v2 compatibility, and runtime performance and reliability.

Compatibility notes

• This release adds append-only D1 migrations 0009 through 0011. No established migration is modified, and there is no destructive or data-rewrite migration.
• Driver protocol v2 is adopted across the API and Driver compatibility paths.
• Task Agent cold continuation now preserves the complete Thread workspace checkpoint. Follow-ups may return a retryable 409 while checkpointing is pending.

Release scope

This GitHub Release publishes the source tag only. It does not deploy production infrastructure or mutate production D1. Deployments from this tag must follow the documented production verification runbook.

Alpha status

Mosoo remains in active Alpha development. Product boundaries, APIs, data models, deployment methods, and management experience may change without backward-compatibility guarantees.
