Upgrading to Clerk Core 2
In April 2024, we updated Clerk's SDKs to include Core 2. This new core includes:
- 💅 Redesigned and improved component UIs.
- 🔪 The 401 & "flash of white page" that was visible sometimes when syncing auth state was eliminated.
- 🧹 A large number of smaller housekeeping changes, bugfixes, and improvements.
- 📊 Telemetry to allow us to better determine feature usage and priority (easy opt-out if you don't like this)
SDK Guides
Core 2 brings both UI changes and breaking code changes, so each SDK has been updated to a new major version. We expect upgrades to take less than 30 minutes, and are providing a CLI tool to assist with the process. Please select your SDK below to get started:
Note that the Gatsby, Go, and Ruby SDKs do not yet have a Core 2 release ready - if you are using any of these SDKs there is nothing actionable right now.
