+* Version 2.0.1 (unreleased)

+** Update SRP extension type and cipher suite with official IANA values.
+This breaks backwards compatibility with SRP in older versions of
+GnuTLS, but this is intentional to speed up the adoption of the
+official values.  The old values we used were incorrect.

+No changes since last version.

-
-       - You cannot assume that sizeof (bool) == 1.

-   Limitations of this substitute, when used in a C89 environment:
-
-       - <stdbool.h> must be #included before the '_Bool' type can be used.
-
-       - You cannot assume that _Bool is a typedef; it might be a macro.
