Claude Code

Version 2.1.140 (May 12)

Subagent matching now accepts case- and separator-insensitive values, so "Code Reviewer" resolves to code-reviewer. /goal no longer hangs silently when disableAllHooks or allowManagedHooksOnly is set. /loop stopped scheduling redundant wakeups. claude --bg connection-dropped errors fixed. Updated agent color palette. [4]

Anthropic

Claude Platform on AWS (May 13, GA)

First cloud provider to offer the native Claude Platform. No separate Anthropic credentials or billing. IAM authentication, CloudTrail audit logs, one AWS invoice. Includes Messages API, Managed Agents beta, advisor tool beta, MCP connector beta, Agent Skills beta, code execution, Files API beta. Opus 4.7, Sonnet 4.6, Haiku 4.5 available. Data is processed outside the AWS security boundary, so pair with Bedrock when you need regional residency. [1][6]

Nothing today.

What This Means For Builders

  • AWS shops can wire Claude into prod without leaving IAM, billing, or CloudTrail. You don't need a parallel Anthropic console.
  • The legal connector dump confirms MCP as Anthropic's distribution wedge. If you ship vertical SaaS, build the MCP server now.
  • Office GA changes what "the assistant" looks like for business users. Plan for Claude inside the document, not next to it.
  • 2.1.140's subagent matching cleanup makes lowercase-hyphenated agent IDs safer in shared team configs.
