As announced previously in our long-term support plan for Composable Commerce SDKs, Version 1 (v1) of our PHP and .NET Core SDKs are now deprecated effective today.

These SDKs will not receive any future updates to fix bugs or security vulnerabilities. If you are using one of these SDKs, you should migrate to PHP v2 or .NET v2. You can find migration guides for both SDKs on their respective pages.
