CrewAI 1.14.7rc1 introduces runtime state management improvements with a new `reset_runtime_state` feature to prevent accumulated bus state, decouples conversation logic from runtime with a `conversational_definition`, and fixes critical issues around runtime state scoping per run to prevent growth and isolate concurrent runs. The release includes bug fixes for telemetry setup and event suppression, along with documentation updates for OpenTelemetry and refactoring improvements to flow condition evaluation and conversation routing.

crewAI releases version 1.14.7rc2, a release candidate that addresses a critical bug in snapshot restoration. The main fix gates the restore functionality on a flag to prevent live snapshots from being replayed during resume operations. This update includes documentation updates to the changelog and version information for the previous rc1 release.

Claude Code v2.1.172 introduces hierarchical sub-agent spawning (up to 5 levels deep), improves AWS region configuration handling for Bedrock, and adds a marketplace search feature.

Performance optimizations reduce CPU usage and improve message handling in long conversations.

This cookbook demonstrates two async multi-agent orchestration patterns using Claude: a fixed N-agent team with peer messaging through a shared hub, and dynamically spawned async subagents. Built on the Anthropic Python SDK and asyncio, it provides bare messaging and lifecycle mechanics without domain-specific tasks, allowing developers to see exactly which tools fire and in what order before adding their own tools and logic. The patterns run on any API key in under thirty seconds and include a message hub, messaging tools (send_message and wait_for_message), and a base agent loop that handles tool dispatching and inbox management.

crewAI v1.14.7a4 introduces runtime migration for @listen/@router decorators to read from FlowDefinition and adds pluggable default backends for memory, knowledge, RAG, and flow components. This release enhances the framework's flexibility by allowing developers to swap backend implementations without code changes. The update includes documentation updates and contributions from three core team members.

OpenClaw v2026.6.5-beta.6 introduces critical fixes for QQBot reasoning stripping, MCP tool result coercion to prevent API errors, improved Anthropic extended-thinking recovery, Parallel web-search provider bundling, and enhanced durability for auth/plugin state via SQLite. The release strengthens security around MCP leases, prompt-cache tool names, and HTTP tools while improving macOS node stability and upgrade safety across multiple platforms.

crewAI v1.14.7a3 is a patch release addressing critical security vulnerabilities and bug fixes. Key improvements include fixing the exposure of `ask_for_human_input` on the experimental AgentExecutor, resolving CVEs in dependencies (aiohttp, docling, docling-core, pip), and refactoring the `@start` decorator to read from FlowDefinition. This release maintains stability while enhancing security posture and internal architecture.

Claude Code v2.1.169 introduces safe mode for troubleshooting, a `/cd` command for directory switching without breaking prompt cache, and a `disableBundledSkills` setting to control skill visibility. The release includes numerous bug fixes for MCP policy enforcement, UI responsiveness, remote session handling, and background agent reliability. Performance improvements reduce CPU usage during streaming and fix stalls on macOS and Windows.

OpenClaw v2026.6.5-beta.3 introduces critical fixes for model reasoning leakage in QQBot, MCP tool result coercion to prevent API errors, improved Anthropic extended-thinking session recovery, and a new bundled Parallel web-search provider. The release strengthens security around tool access, improves provider/model resolution reliability, and enhances durability of auth and plugin state through SQLite persistence. Multiple platform-specific improvements address macOS node reconnection issues, Matrix voice/thread handling, and mobile UI clarity.

OpenClaw v2026.6.5-beta.5 introduces critical stability and safety improvements across multiple channels and providers. Key fixes include QQBot reasoning stripping, MCP tool result coercion to prevent API errors, Anthropic extended-thinking session recovery, and Parallel web-search bundling. The release strengthens auth durability, provider model resolution, and agent/tool/provider loop safety while improving macOS node mode reliability and upgrade path safety.

Claude Code v2.1.166 introduces fallback model configuration for improved reliability, adds glob pattern support for tool access control, and hardens cross-session messaging security. The release includes numerous bug fixes for terminal compatibility, image processing, remote sessions, and managed settings enforcement. Key improvements enhance user experience across JetBrains IDEs, terminal protocols, and background agent sessions.

crewAI v1.14.7a2 introduces conversational flow traces support with enhanced LLM event transparency, including real finish_reason, sampling parameters, and response IDs. The release refactors the flow DSL into focused decorator modules and implements a chat API for conversational flows. Key improvements include type-aware route decorators, overridable locking backends, and flattened LiteLLM usage tracking, alongside new NVIDIA Nemotron documentation and monorepo deployment guides.

Claude Code v2.1.163 introduces version management controls via `requiredMinimumVersion` and `requiredMaximumVersion` settings, adds a `/plugin list` command with filtering, and enhances the `/btw` command with clipboard copying. The release includes significant bug fixes for bash command execution on Windows/Bazel/EDR systems, background session management, terminal responsiveness, and permission rule application. Multiple stability improvements address hook conditions, keyboard input, and background agent updates.

Claude Code v2.1.162 introduces improved session management with the `waitingFor` field in JSON output, enhanced slash command behavior with confirmation before execution, and a persistent Remote Control footer. The release fixes critical issues including read-only config directory handling, WebFetch permission precedence, Windows path matching in permission rules, and MCP timeout configuration. UI improvements include quieter startup messaging, full terminal-width status display, and better error reporting across agents, LSP tools, and cross-session messaging.

crewAI 1.14.7a1 introduces native Snowflake Cortex LLM provider support and crew trained agents file functionality.
