+## 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
