v1.1.2

Changes and Fixes

• Resolved dependency audit findings by moving runtime and development locks to fixed package versions and tightening minimum constraints where needed.
• Simplified redundant internal code paths identified by the audit without changing public behavior.
• Reduced Dependabot noise from protobuf major updates that cannot satisfy the current package constraints.

Full changelog: v1.1.1...v1.1.2

v1.1.1

Changes and Fixes

• Refined internal helper boundaries and serve CLI guidance, with targeted regression coverage to keep the cleanup safe.

Full changelog: v1.1.0...v1.1.1

v1.1.0

Contract Changes

• Clarified successful non-streaming message:send result semantics: full assistant output is carried in Task.artifacts, while terminal Task.status.message remains a short completion status.
• Canonicalized opencode-a2a extension identifiers to urn:opencode-a2a:extension:<contract>:v1 and narrowed shared streaming disclosure to the stable public contract fields.

Changes and Fixes

• Redacted sensitive query parameters from database URLs in persistence and SDK compatibility logs.
• Tightened local compatibility surfaces for session-query and client transport inputs, with broader regression coverage for parsing, CLI, error mapping, interrupt, and extension-contract behavior.
• Split doctor.sh into explicit fix, verify, and package phases while keeping ./scripts/doctor.sh as the standard validation entrypoint.

Full changelog: v1.0.0...v1.1.0

v1.0.0

Breaking Changes

• opencode-a2a v1.0.0 is a breaking release that supports only the A2A 1.0 protocol line.
• If you need compatibility with A2A 0.3, stay on v0.8.2.

New Features

• Added durable database-backed runtime stores for task state, push configuration, and SDK compatibility data so long-running and reconnecting task flows preserve consistent state across runtime boundaries.

Changes and Fixes

• Completed the migration to a2a-sdk 1.0 and finalized the runtime, discovery, and extension-contract surfaces around the A2A 1.0 wire model.
• Tightened task output, stream artifact, terminal-state, and provider-private contract behavior so send, stream, reconnect, and follow-up task reads stay aligned under the 1.0 runtime.

Full changelog: v0.8.2...v1.0.0

v0.8.2

Changes and Fixes

• Reduced default runtime log noise by downgrading normal or recoverable control-flow logs to DEBUG, including client disconnect cleanup, stream retries, snapshot rewrite suppression, and local upstream concurrency backpressure.
• Reported mapped OpenCode HTTP status and timeout failures as default WARNING summaries while keeping traceback details available at DEBUG.
• Replaced raw request text, response text, and stream chunk content in non-payload debug logs with length fields such as text_len and content_len.
• Clarified documentation that lightweight metric log records are emitted at A2A_LOG_LEVEL=DEBUG.

Full changelog: v0.8.1...v0.8.2

v0.8.1

Changes and Fixes

• Aligned SDK ClientConfig.polling with the existing opencode A2A client polling fallback policy.
• Preserved the default blocking message/send behavior by keeping SDK polling disabled unless the fallback policy is enabled.

Full changelog: v0.8.0...v0.8.1

v0.8.0

New Features

• Added persisted task-scoped output negotiation so acceptedOutputModes is normalized, stored in task metadata, and applied across send, stream, get, resubscribe, and list flows.
• Added a stable text fallback for structured DataPart outputs when clients accept text/plain but not application/json.

Changes and Fixes

• Consolidated session-claim flow, upstream error mapping, metadata access, parsing helpers, and terminal-state constants to reduce JSON-RPC and runtime drift.
• Preserved wire behavior while tightening output-mode and extension-contract consistency across runtime surfaces.

Maintenance

• Added maintainer architecture and compatibility docs.
• Expanded the default doctor.sh validation baseline with mypy, release artifact generation, and built-wheel smoke testing.
• Added the Dependabot baseline and simplified dependency update flow.

Full changelog: v0.7.1...v0.8.0

v0.7.1

Changes and Fixes

• Added an explicit pygments>=2.20.0,<3.0 dev-extra constraint and refreshed the lockfile so development dependency audit no longer resolves a vulnerable version.

Maintenance

• Renamed validation and dependency review workflow files and tightened workflow, job, and step labels.
• Kept the publish workflow filename stable for the existing PyPI trusted publishing configuration.

Full changelog: v0.7.0...v0.7.1

v0.7.0

New Features

• Added a static auth registry and capability-based runtime authorization for extension access.
• Added versioned state-store migrations and sqlite-first durability hardening for upgrade-safe persistence.
• Added A2A dual-stack compatibility foundations.
• Added W3C trace-context propagation into runtime logs for request correlation.

Changes and Fixes

• Tightened unsupported extension boundaries and runtime authorization behavior.
• Aligned media modes and output negotiation behavior across server, runtime, and client-facing surfaces.
• Clarified subtask compatibility and extension boundary documentation.

Maintenance

• Split server application and execution orchestration modules to reduce coupling.
• Added conformance workflow coverage for compatibility investigations.
• Hardened package hygiene and packaging smoke coverage.

Full changelog: v0.6.1...v0.7.0

v0.6.1

Changes and Fixes

• Backfilled the legacy SQLite interrupt-request details_json column during startup for upgraded durable-state deployments.
• Added A2A_HTTP_GZIP_MINIMUM_SIZE and raised the default gzip threshold to 8192 for non-streaming responses.

Maintenance

• Hardened publish release recovery so manual recovery runs are tag-aware, idempotent, retryable, and default away from duplicate PyPI publish attempts.
