Fable 5 Frozen by Export Order, v2.1.183 Blocks Destructive Commands, TypeScript SDK Gets code_execution Tool

Fable 5 and Mythos 5 suspended globally by US export order; restoration negotiations stalled by NSA breach claim

• Fable 5 launched to wide developer acclaim on June 9; within 96 hours a US government export control order (June 12-13) forced Anthropic to suspend both Fable 5 and Mythos 5 worldwide.
• By June 16 security leaders were publicly calling for the controls to be lifted and Anthropic and Trump officials began negotiating a restoration deal, reportedly aided by G7 discussions.
• As of June 21, both models remain offline - an NSA breach claim has since complicated the talks and no restoration date has been announced.

Editor’s read: If you hardcoded claude-fable-5 or claude-mythos-5 anywhere, your agents are silently broken right now - fix this before anything else.

Anthropic TypeScript SDK v0.105.0: native code_execution tool and lazy partial JSON parsing across all platform variants

• On June 18, Anthropic released TypeScript SDK v0.105.0 adding a first-class code_execution tool and lazy partial JSON parsing for streaming tool calls; the same lazy-parsing update shipped simultaneously to Bedrock (v0.31.0), Vertex (v0.18.0), Foundry (v0.4.0), and AWS (v0.5.0) SDK variants.

v2.1.183: Automatic blocking of destructive git commands and deprecated model warnings (June 19)

• Released June 19, v2.1.183 blocks destructive git commands (force-push, reset --hard, branch -D) in auto mode by default and surfaces deprecation warnings whenever a config references a deprecated or unavailable model ID.
• critical now that Fable 5 and Mythos 5 are suspended.

Editor’s read: The destructive git blocking is on by default in auto mode - test your CI workflows before upgrading to ensure intended force operations still work.

v2.1.185: Stream-stall messaging and retry timing improvements (June 21)

• Released June 21, v2.1.185 improves user messaging when the stream stalls mid-response and tunes retry timing, making long-running agentic sessions more resilient to transient network issues.

Agent SDK Python v0.2.102-v0.2.106: five releases tracking CLI cadence (June 15-20)

• Five Python SDK releases shipped between June 15 and June 20 (v0.2.102 through v0.2.106), each primarily bumping the bundled Claude CLI to match the corresponding Claude Code release; v0.2.104 bundles CLI v2.1.181 and v0.2.105 bundles v2.1.183.

Agent SDK TypeScript v0.3.178-v0.3.185: SDKRateLimitInfo fields and tool_use_meta icon_url added in v0.3.181

• The TypeScript SDK tracked the same release cadence (v0.3.178 through v0.3.185); the substantive additions are in v0.3.181, which adds SDKRateLimitInfo fields for programmatic rate-limit introspection and tool_use_meta icon_url for custom tool icon rendering in agent UIs.

Editor’s read: SDKRateLimitInfo lets you back off intelligently instead of guessing - wire it into your retry logic.

modelcontextprotocol/servers 2026.6.16 maintenance release (June 16)
