           Flowed format: The 'flowed_insert_crlf' entry in configfile adds an
            empty line separator after every paragraph that ends with an empty

           TLS module can now use OpenSSL 3 API (required for FFDHE group
            negotiation with TLSv1.2 and TLSv1.3 protocols)
           TLS module can now use LibreSSL 3 (formerly major version 2 was used
            to identify LibreSSL and distinguish it from OpenSSL)
           TLS modules compile time option 'CFG_USE_TLS_OWNCERTS' replaced by
            the new 'tls_owncerts' entry in configfile
           TLS modules experimental compile time option 'CFG_USE_TLS_CRLS'
            replaced by normal option 'CFG_TLS_CRLS_DISABLE'. Default is to use
            no CRLs (former behaviour) because this option increases the system
            requirements (to POSIX.1-2001 or XSI extension)
           TLS module now supports new 'crl_check' entry in configfile (ignored
            if CFG_TLS_CRLS_DISABLE is nonzero)
           TLS module now prints real LibreSSL version instead of generic 2.0.0
           TLS module no longer supports options 'CFG_USE_TLS_DHPARAM_CHECK' and
            'CFG_USE_TLS_SETSIGALG'. They were obsoleted by the OpenSSL 1.1 API
           Unicode database updated to version 12.1.0
           GUI module no longer supports experimental FLTK 1.3 option
            'USE_X11_GLYPH_SUBSTITUTION'. It was obsoleted by FLTK 1.4
           Modified LaTeX documentation to work with recent doxygen
