Type definitions missing for sequential prop

[dokdo2013]

After updating to version 2.6.0, TypeScript type definitions have not been updated to include proper type checking for the new sequential prop.

Expected Behavior:
The sequential prop should have updated type definitions to ensure proper type checking.
