We are releasing an updated Mono Framework to the Stable channel. A bug has been identified as a critical issue affecting some internal tests, and we felt that releasing the fix was a priority.
The issue is caused by a new feature in El Capitan called System Integrity Protection (SIP). One of the changes resulting from SIP is that any environment variables prefixed with DYLD_* are blanked out when launching protected processes. This caused problems for some applications, and in particular some features of Xamarin Studio.
