• Added system properties to allow manipulation of various crypto algorithms used by default
• Integrated JZlib, allowing use of zlib@openssh.com & zlib compressions without the need to provide the JZlib jar-file
• Modularized the jar-file for use with Java 9 or newer
• Added runtime controls for the min/max/preferred sizes used for diffie-hellman-group-exchange-sha256 & diffie-hellman-group-exchange-sha1
• Renamed PubkeyAcceptedKeyTypes config to PubkeyAcceptedAlgorithms to match recent changes in OpenSSH (PubkeyAcceptedKeyTypes is still accepted for backward compatibility)
• Reduced number of algorithms that are runtime checked by default via CheckCiphers, CheckMacs, CheckKExes & CheckSignatures to improve runtime performance
