v0.2.113

What's changed

• Changed the SDK to spawn a native Claude Code binary (via a per-platform optional dependency) instead of bundled JavaScript
• Added sessionStore option (alpha) to query() and session helpers for mirroring session transcripts to external storage, with SessionStore/SessionKey/SessionStoreEntry types, InMemorySessionStore reference implementation, and importSessionToStore() for migrating existing sessions
• Added deleteSession() for removing a session from disk or a SessionStore
• Added SDKMirrorErrorMessage (subtype: 'mirror_error') to the SDKMessage union — emitted when a sessionStore.append() batch fails
• Breaking: options.env once again replaces process.env for the CLI subprocess instead of overlaying it. To add or override individual variables, pass env: { ...process.env, MY_VAR: "x" }
• Added title option to query() — sets the session title and skips auto-generation
• Added OpenTelemetry trace context propagation — the caller's active trace context is forwarded to the CLI subprocess so spans parent under your distributed trace

What's changed

• Opus 4.7 is now available! This version of the SDK is required to use it.

v0.2.110

What's changed

• Fixed unstable_v2_createSession not respecting cwd, settingSources, and allowDangerouslySkipPermissions options
