New Features between 2.0.x and 2.1.x

• Better ming Windows build support.
• Added -E flag to allow multicast ethernet traffic.

Draft changelog between 2.8.x and 2.9.x (as of February 8, 2021)

New Features

• Federated supernodes to allow multiple supernodes for load balancing and fail-over (doc/Federation.md)
• Automatic IP address assignment allows edges to draw IP addresses from the supernode (just skip -a)
• Allowed community names can be restricted by regular expressions (community.list file)
• Network filter for rules (-R) allowing and denying specific traffic to tunnel
• Experimental TCP support (-S2) lets edges connect to the supernodes via TCP in case firewalls block UDP
• All four supported ciphers offer integrated versions rendering OpenSSL dependency non-mandatory (optionally still available)
• MAC and IP address spoofing prevention
• Network interface metric can be set by command-line option -x (Windows only)
• Re-enabled local peer detection by multicast on Windows
• Edge identifier (-I) helps to identify edges more easily in management port output

Improvements

• Fixed a compression-related memeory leak
• Ciphers partly come with platform-specific hardware acceleration (check tools/n2n-benchmark)
• Clean-up management port output
• Polished benchmark tool output
• Reactivated send out of gratuitous ARP packet on establishing connection
• Enhanced documentation (doc/ folder) including the man pages and command-line help text
• Self-monitoring time stamp accuracy for use on systems with less accurate clocks
• Fixed man pages' and config files' paths
• Code clean-up
