+
+Due to a bug, we were using the undocumented `ssl_key` config option to define the CA bundle in CURLRequest.
+This was fixed and is now working according to documentation. You can define your CA bundle via the `verify` option.

+CURLRequest option `ssl_key` it's not recognized anymore.

+CURLRequest option `verify` can also take *boolean* values as usual.
