@ -35,6 +35,7 @@ Changes
* Changed the used random function pointer to more flexible format. Renamed
havege_rand() to havege_random() to prevent mistakes. Lots of changes as
a consequence in library code and programs
* Moved all examples programs to use the new entropy and CTR_DRBG
* Added permissive certificate parsing to x509parse_crt() and
x509parse_crtfile(). With permissive parsing the parsing does not stop on
encountering a parse-error
