Agent Development Kit (ADK) 2.14.0 released
A major release graduating experimental features to stable, adding multi-run evaluation and semantic argument matching, and introducing Microsoft Teams and OpenAI Decisions integrations.
What changed in 2.14.0
- Execution environments, A2A, evaluation, and core runtime modules are now stable; large file reads and writes stream in chunks to avoid memory issues.
- Multi-run evaluation runs each case multiple times concurrently with
MultiRunConfigand--parallelism, andToolArgsMatchercompares tool arguments using exact, case-insensitive, numeric, or semantic checks. - New
TeamsRunnerintegrates agents with Microsoft Teams,OpenAIDecisionsClassifiergates workflows with the OpenAI Decisions API, andMongoDbMemoryServiceadds vector search. - Long multi-turn workflows are 23% faster with 9% lower peak memory; 26 auth, environment, and app modules plus 16 toolset features graduate from experimental.
AgentEvaluatoraccepts agents built at runtime, and--eval_storage_uristores evaluation files outside read-only agent directories.
Check before you update
- Enum tool parameters now receive enum members instead of strings; code comparing against strings or using string methods must use
.valueor switch toStrEnum. VertexAiSessionService.create_sessionaccepts onlydisplay_name,ttl,expire_time, andlabels; other config keys now raiseValueError.RunSkillScriptToolwithSkillToolsetenvironment no longer acceptscommand; scripts receiveargs,short_options, andpositional_argsinstead, and only.py,.sh, and.bashscripts are supported.
