Caldera Forms 1.4.9.1 is a bug fix release with one change, but this change is very important for users of our PayPal add-on. In Caldera Forms 1.4.9 when returning from PayPal, the form submission could not be completed. This bug has been fixed in 1.4.9.1 and will not be present in Caldera Forms 1.5, which will be released on Tuesday.
We appologize for this error.
