adk_dart 2026.3.2+1

Core Dart port of Agent Development Kit (ADK) runtime primitives.

Unreleased

2026.3.2+1

• Bumped package release versions using build metadata (2026.3.2+1) for adk_dart, adk, adk_mcp, and flutter_adk.
• Improved adk CLI parity for run/web/conformance flows to better match adk-python behavior.
• Fixed adk run . project path resolution when running from the agent directory.
• Updated conformance client/server wiring (/apps/.../sessions, /run_sse) and replay validation/report handling, including non-zero exit on test failures.
• Hardened local .adk path handling and project directory validation, with expanded CLI/web regression tests.

2026.3.2

• Bumped package release versions to 2026.3.2.
• Updated cross-package dependency alignment (adk_dart / adk / adk_mcp / flutter_adk) for the new release.

2026.3.1

• Hardened A2A push callback delivery with a persistent SQLite queue, retry/backoff policy handling, startup/background drain, and dead-letter capture.
• Added A2A delivery reliability coverage in test/dev_web_server_test.dart, including persisted queue replay after restart.
• Added live network backend integration tests for PostgreSQL/MySQL session services (env-gated via ADK_TEST_POSTGRES_URL / ADK_TEST_MYSQL_URL).
• Added unified runtime adapter bootstrap APIs: configureToolRuntimeBootstrap(...) and resetToolRuntimeBootstrap(...).
• Added global default audio recognizer registration support via AudioTranscriber.registerDefaultRecognizer(...).
• Added bundled default runtime clients for BigQuery, Bigtable (admin/data), and Spanner (REST-based), removing mandatory client-factory injection for core paths.
• Added token resolution fallbacks for default cloud clients (explicit oauth token, environment variables, gcloud ADC, metadata server).
• Added built-in default Spanner embedder runtime via Vertex AI predict API (with env/full-model resource fallback handling and explicit fallback guidance).
• Added built-in default Toolbox HTTP delegate (/api/toolset/*, /api/tool/*/invoke) so ToolboxToolset can run without pre-registered delegate wiring.
• Added built-in live HTTP/auth providers in GcsArtifactService, removing mandatory provider injection for direct service usage.
• Ported telemetry parity for inference span/experimental semconv paths and added regression coverage.
• Added telemetry parity worklog and aligned package release versions to 2026.3.1.
• Updated parity tests to validate concrete default Bigtable/Spanner client availability.
• Refreshed runtime checklist and README feature matrix to reflect current implemented behavior.

2026.2.28

• Switched package versioning scheme to date-based YYYY.M.D.
• Expanded adk web / adk api_server parity surface with bundled /dev-ui serving and broader API route compatibility.
• Hardened MCP transport/session behavior through adk_mcp integration updates and related tests.
• Replaced deprecated mysql1 runtime dependency with mysql_client_plus in network session backend wiring.
• Added MySQL secure-fallback connect behavior for auth plugins that require TLS (for example caching_sha2_password).
• Added MySQL TLS hardening options (ssl_ca_file, ssl_cert_file/ssl_key_file, ssl_verify) with fail-fast validation for invalid TLS file configuration.
• Added runtime gap audit document for remaining non-functional/default-unwired features.

0.1.2

• Added package topics metadata on pub.dev to improve discoverability.

0.1.1

• Expanded Python parity coverage across evaluator workflows and remote code executor paths.
• Added parity ports for model contracts and toolset stacks, including Google API, Pub/Sub, and OpenAPI integrations.
• Added Spanner, Bigtable, and BigQuery client/toolset parity layers with vector store and metadata/query support.
• Added session schema/migration utilities and missing shared utility modules.

0.1.0

• Bootstrap adk_dart package as an ADK core runtime port (based on ref/adk-python).
• Added core agent/session/event/tool/model abstractions and execution flow.
• Added Runner / InMemoryRunner with async invocation path.
• Added function-call orchestration in LLM flow.
• Added baseline tests for event behavior, session service, and runner flow.
