Three enhancements landed this month:
Stricter MFA controls — The mfa_validation_required decorator now accepts a single_use parameter, letting you require MFA verification on every request instead of once per session. Useful for high-security workflows.

Windows frontend support — Frontend builds now run natively on Windows. pnpm's built-in Node version management replaces the nvm requirement, which was Linux/Mac-only.
Enhanced SS0 — The new IS_ENHANCED_SSO attribute simplifies integration with Q2's enhanced SSO flows and ships with built-in template support.
We're planning to upgrade to Swift 6 in an upcoming iOS release. Timing isn't finalized yet, but the upgrade may introduce language, compiler, and dependency compatibility changes.
What to do now: Start reviewing your modules and any third-party dependencies for Swift 6 readiness. We'll share detailed timelines as they firm up.
