Modal 1.3.3
- We've added a new modal billing report CLI and promoted the modal.billing.workspace_billing_report API to General Availability for all Team and Enterprise plan workspaces. We've added modal.Queue.from_id() and modal.Dict.from_id() methods to support referencing a Queue or Dict by its object id. Modal's async usage warnings are now enabled by default.
PostHog is now available in Vercel’s v0
PostHog has extended its Vercel integration to v0 via MCP. This allows v0 to generate code based on real product data, including experiment results and feature flag states.
GA Versions for the G&S iOS, Android, and React Native SDKs
After nearly a year of development, rigorous testing, and deep collaboration with users, our mobile SDKs are officially ready for production! Version 3.0.0 introduces a new "Minimum SDK version" kill switch, giving you an added layer of safety to protect deployments.
Duplicate Guides and Surveys across Platforms
Just in time for Guides and Surveys' mobile GA launch, we added the capability to copy a guide or survey to a different platform (app). Simply use the existing 'Duplicate' buttons which will now trigger a platform selection modal in case you have multiple platforms configured. Why: Customers often want to show the same message on all of their apps.
