+> **Note**
+> As part of our ongoing commitment to best security practices, we have rotated the signing keys used to sign previous releases of this SDK. As a result, new patch builds have been released using the new signing key. Please upgrade at your earliest convenience.
+> 
+> While this change won't affect most developers, if you have implemented a dependency signature validation step in your build process, you may notice a warning that past releases can't be verified. This is expected, and a result of the key rotation process. Updating to the latest version will resolve this for you.
