Claude Code CLI now spawns a native platform binary instead of bundled JavaScript; npm install delivers the same binary via per-platform optional dependencies
Claude in Amazon Bedrock is now GA and open to all customers — Claude Opus 4.7 and Haiku 4.5 available self-serve in 27 AWS regions with global and regional endpoints
All Anthropic SDKs (Python, TypeScript, Go, Java, Ruby, C#) now expose a new BedrockMantle client class targeting the Messages API endpoint on Bedrock, recommended for all new projects
New sandbox.network.deniedDomains setting lets you block specific domains even when a broader wildcard allowedDomains rule would otherwise permit them
Three security improvements to the permission system: macOS dangerous-path detection, exec-wrapper bypass prevention, and find -exec/-delete auto-approval removed
Updated runtime dependencies note: both SDK packages now bundle a native Claude Code binary for the host platform; no separate Claude Code or Node.js install is needed for the spawned CLI. [line 19] [Source]
Added note that the TypeScript SDK bundles a native Claude Code binary as an optional dependency — no separate Claude Code install required. [line 53] [Source]
Added note that the SDK bundles a native Claude Code binary via optional dependency; pathToClaudeCodeExecutable is only needed if optional dependencies were skipped or the platform is unsupported. [lines 10-11] [Source]
Clarified pathToClaudeCodeExecutable option description — auto-resolved from bundled native binary by default. [line 340] [Source]
Clarified the once field: it is only honored for hooks declared in skill frontmatter; it is ignored in settings files and agent frontmatter. [line 283] [Source]
Added clarification that the opusplan model alias uses the standard 200K context window during the plan-mode Opus phase; the automatic 1M upgrade for the opus setting does not extend to opusplan. [line 136] [Source]
npm installation is no longer marked as deprecated; the section now explains that npm install -g @anthropic-ai/claude-code installs the same native binary as the standalone installer via per-platform optional dependencies. [lines 265-278] [Source]
Listed the eight supported npm install platforms. [line 276] [Source]
New troubleshooting section "Native binary not found after npm install" covering three causes: optional dependencies disabled, unsupported platform, and corporate npm mirror missing platform packages. Also notes that --ignore-scripts skips the postinstall link step and causes a slower fallback. [lines 587-598] [Source]
Updated footnote: Claude Opus 4.7 on AWS is now available through the full Claude in Amazon Bedrock endpoint (no longer a research preview). [line 36] [Source]
Updated AWS Bedrock links to point to the new claude-in-amazon-bedrock doc; added distinction between the new Messages-API endpoint (Opus 4.7, Haiku 4.5, newer models) and the legacy integration. [lines 35-54] [Source]
Added AnthropicBedrockMantleClient for the Messages-API Bedrock endpoint; AnthropicBedrockClient (legacy InvokeModel path) remains available. Recommended to use AnthropicBedrockMantleClient for new projects. [lines 415-418] [Source]
Added bedrock.NewMantleClient for the Messages-API Bedrock endpoint (SSE streaming); legacy WithLoadDefaultConfig/WithConfig remain for InvokeModel apps. Recommended to use NewMantleClient for new projects. [lines 534-537] [Source]
Added AnthropicBedrockMantle client for the Messages-API Bedrock endpoint; AnthropicBedrock remains for legacy InvokeModel apps. Updated client table from three to four clients. [lines 724-729] [Source]
Added AnthropicBedrockMantle client from @anthropic-ai/bedrock-sdk for the Messages-API Bedrock endpoint; AnthropicBedrock remains for legacy InvokeModel apps. [lines 771-775] [Source]
GA announcement: Claude in Amazon Bedrock is now open to all customers (was research preview). Claude Opus 4.7 and Haiku 4.5 are self-serve; Claude Mythos Preview remains invitation-only. [line 11] [Source]
Prerequisites updated: now only requires standard Bedrock model access, not a dedicated allowlisted account (except for Mythos Preview). [lines 17-23] [Source]
Added supported model table with model IDs and access levels. [lines 169-173] [Source]
Added comprehensive region availability table covering 27 AWS regions with global, regional, and inference-profile endpoint types. [lines 197-232] [Source]
Data retention section updated: now governed by Amazon Bedrock (AWS); ZDR is available by contacting AWS support. [lines 238-241] [Source]
Page renamed to "Claude on Amazon Bedrock (legacy)" and intro updated to clarify it covers the InvokeModel/Converse APIs with ARN-versioned model IDs; new endpoint documented in claude-in-amazon-bedrock. [lines 1-7] [Source]
Added note that Claude Opus 4.7 is reachable via InvokeModel on bedrock-runtime but lacks an ARN-versioned model ID; full feature parity requires the new Bedrock endpoint. [lines 68-76] [Source]
Updated platform availability: Claude Opus 4.7 and Claude Mythos Preview are now available for structured outputs through the Claude in Amazon Bedrock Messages-API endpoint (previously only in research preview). [line 12] [Source]
Added April 18, 2026 entry: Claude in Amazon Bedrock is now GA and open to all customers, with Claude Opus 4.7 and Haiku 4.5 available self-serve in 27 AWS regions. [line 12] [Source]
