“Generate a detailed report of feature release and distribution by all the agentic frameworks and protocols lat week”
“Last week” is the completed Monday–Sunday window of Aug 24–30, 2026. A broad live-web scan verified 27 releases, rollouts and launches across 12 agentic ecosystems — frameworks (Pydantic AI, Google ADK, Microsoft Agent Framework, LangChain, Agno, Mastra), the MCP protocol stack, and new harnesses — each carried here with its delivery route and source.
Hover a marker for what shipped. Jakarta Agentic AI 1.0.0-M1 has no verifiable tag date and sits in the undated row rather than a guessed day.
clai --mcp-config with tool-call streaming closed it on Friday, with capability-field deprecations and Bedrock guardrail trace propagation in between — github.comFastest cadence in the index: LangChain migration skill (v2.34.0), capability-field deprecations (v2.35.0), Bedrock guardrail trace propagation (v2.35.1), Heroku GLM routing via zai_model_profile (v2.35.3), clai --mcp-config and tool-call streaming (v2.36.0). github.com
v2.8.0: native A2A task mode for RemoteA2aAgent, ADK_MAX_LLM_CALLS control, create/delete data-agent tools, Model Armor guardrail plugin, Nvidia NIM sample. v1.39.1 backports A2A allowlisting, artifact storage/scoping and security validations. github.com
Python 1.16.0 tagged on Aug 27; separately, Channels (Aug 26) is a set of open-source Python packages connecting one agent or workflow to many platforms and protocols at once, complementing MCP and A2A support. github.com
Python SDK 2.1.0, PHP SDK v0.8.0 (full 2026-07-28 spec: stateless lifecycle, header validation, multi round-trip requests, extensions, deprecations), Inspector 2.4.0, github-mcp-server 1.11.0, enterprise-managed connector auth GA. mcp-news.com
Managed Deep Agents and LangSmith LLM Gateway public betas (AWS BYOC, runtime controls for production agents) plus Deep Agents v0.7 with Tuned Evaluators. aitoolly.com
Codex harness open-sourced under Apache-2.0 with a bidirectional JSON-RPC app server, deprecating codex mcp-server; Headlong’s always-on Bash agent loop; Agent Lightning v1.0.1 agent-optimizer skill; CodeCrew 1.0; AgentConnect; Jakarta Agentic AI 1.0.0-M1. groundtruth.day
Pydantic AI ×5, ADK ×2, agent-framework 1.16.0, Agno 3.0.0/3.0.2, the Mastra package wave (@mastra/core 1.62–1.63, deployer, dsql, factory), Deep Agents v0.7, CodeCrew 1.0.0 — install by tag or package manager.
LangChain’s Managed Deep Agents and LangSmith LLM Gateway entered public beta (with AWS BYOC); Anthropic’s enterprise-managed MCP connector authorization reached general availability — features arrive server-side, nothing to install.
Python SDK 2.1.0 and PHP SDK v0.8.0 via language package ecosystems; Inspector 2.4.0 and github-mcp-server 1.11.0 as tooling releases. The spec itself did not move; its 2026-07-28 revision propagated through SDKs.
Codex harness open-sourced under Apache-2.0; Headlong as a dependency-light Bash microharness; Channels as open-source Python packages; Agent Lightning installed through gh skill; AgentConnect as open source; Puppyone v0.3.13 as a signed, notarized desktop build.
Stable after four alphas; run the database migration first. 3.0.2 then changes metadata precedence to component → session → call-site on Agent, Team and Workflow. mindpattern.ai
Handler exception text no longer reaches the model, and the 4 MiB body cap now also covers SSE and OAuth — audit error-handling paths before upgrading. mindpattern.ai
v2.35.0 deprecates capability_loaded and available_capability_ids; the PHP SDK carries the spec’s SEP-2577 deprecations of Roots, Sampling and Logging; Codex deprecates codex mcp-server in favor of the app server. github.com
Headlong’s always-on loop carries a reported shared-thought-stream access-control caveat. Google ADK v1.39.1 backports A2A allowlisting, app-scoped artifact storage and security validation fixes to the v1 branch. byteiota.com

Method: broad live-web scan for agentic framework and protocol releases in the completed week Mon Aug 24 – Sun Aug 30, 2026; 27 verified items merged from ~128 evidence rows across five extraction sets. Official GitHub release pages and vendor blogs are treated as primary sources; news and industry summaries as secondary. A release date is used only when the source text states it — Jakarta Agentic AI 1.0.0-M1 is left undated. “Type” distinguishes a package/tag release from a hosted rollout, protocol SDK/tooling, or a source launch. Adjacent items outside the agentic-framework scope (editors, model runtimes, vendor platform launches such as AgentZ) were cut for space; the scan cannot claim capture of private or unindexed projects.
