• New stable release incorporating all changes from developer releases
  1.89_01 to 1.89_05.
  
• Summary of major changes since version 1.88:
  
  • Formalised libssl version support policy: all stable versions of OpenSSL
    in the 0.9.8 - 1.1.1 branches (with the exception of 0.9.8 - 0.9.8b) and
    all stable releases of LibreSSL in the 2.0 - 3.1 series are supported.
    The LibreSSL 3.2 series is not yet fully supported because its TLSv1.3
    implementation is not currently libssl-compatible.
    
  • Added support for LibreSSL on Windows when built with Visual C++.
    
  • Exposed P_X509_CRL_add_extensions, several SSL_CIPHER functions, and
    several stack functions.
    
  • Fixed crashes in the callback functions CTX_set_next_proto_select_cb and
    CTX_set_alpn_select_cb.
    
  • The test suite is now compatible with OpenSSL 1.1.1e onwards, as well as
    OpenSSL security level 2 (the default on many Linux distributions).
