+Porting Information
+-------------------
+
+When moving from Mesa 4.0.x to Mesa 4.1 there are a number of things
+you may have to update.
+
+1. _mesa_create_context() changes.  This function now takes a pointer to
+   a __GLimports object.  The __GLimports structure contains function
+   pointers to system functions like fprintf(), malloc(), etc.
+   The _mesa_init_default_imports() function can be used to initialize
+   a __GLimports object.  Most device drivers (like the DRI drivers)
+   should use this.
+
+2. more to come...
