adk-python 2.14 sandboxes, OpenCode 2.2.6 MCP pooling
Updated 1 min read
Summary
Agent Radar 2026-11-07: adk-python 2.14.0 makes sandboxes and A2A stable; OpenCode 2.2.6 adds MCP pooling and worktree runs. Plus Google ADK alternatives.
Agent Radar tracked two launches as of 2026-11-07, covering the window 2026-10-31 to 2026-11-07 for tools we have not written about this week. Preview, nightly, alpha, dev and release-candidate builds were left out.
At a glance
| Launch | Tool | Released | What changed |
|---|---|---|---|
| adk-python 2.14.0 makes sandboxes and A2A stable | adk-python | 2026-11-07 | Stable Local, E2B and Daytona environments; stable A2A; adk eval --num_runs; Teams runner; breaking enum, Vertex session and skill-script changes |
| OpenCode 2.2.6 adds MCP pooling and worktree runs | OpenCode | 2026-11-06 | pool: true for MCP servers; opencode run --worktree and --archived; GUI plugin themes; runs wait for background jobs |
What changed
- ADK sandboxes are stable:
E2BEnvironment,DaytonaEnvironmentandLocalEnvironmentleave experimental, and skill scripts can no longer receive a free-form shellcommand, which the notes say closes a prompt-injection hole. - ADK rollback warning: Firestore sessions written by 2.14.0 cannot be read by 2.13.0 or earlier.
- OpenCode in CI:
opencode runnow waits for background jobs with no time limit, so a prompt that starts a dev server keeps the job open. Add a timeout.
Questions
Is adk-python 2.14.0 a breaking release?
Yes, in three places: enum tool arguments now arrive as enum members, VertexAiSessionService.create_session accepts fewer options, and RunSkillScriptTool no longer takes command.
What if ADK is not the right framework for me? Our new guide, Google ADK alternatives, compares LangGraph, Pydantic AI, the OpenAI Agents SDK, Microsoft Agent Framework and Mastra. For OpenCode, see OpenCode vs Cline vs Aider.
