 Changes between 0.9.8a and 0.9.8b  [XX xxx XXXX]



  *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support

     opaque EVP_CIPHER_CTX handling.

     [Steve Henson]



  *) Several fixes and enhancements to the OID generation code. The old code

     sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't

     handle numbers larger than ULONG_MAX, truncated printing and had a
