## Release notes
+### Version 0.12
+
+Ensures C++11 compliance to correct gcc 11 compilation errors. On the other
+hand, this introduces API breaks.
+
+According to the C++11 standard, the min/max values of a
+UniformRandomBitGenerator must be static constant expressions. But until now,
+gcc has been flexible enough to allow the use of UniformRandomBitGenerators
+with regular min/max values. At run time, the caller could thus define its own
+RNG type as provided by the struct `ssp_rng_type` data structure.
+Unfortunately, since its version 11, gcc is more severe and refuses to compile
+this code.
+
+This version updates the API to respect this C++11 constraint. The
+`ssp_rng_type` is no longer a structure; it becomes an enumeration which is
+then instantiated internally in a specific UniformRandomBitGenerator with
+min/max values resolved at compilation time.
