#### n2n 2.4 (August 2018) |
## n2n 2.8 (August 2020) |
||||
|
|
||||
|
This release brings significant new features to n2n's crypto world and offers |
||||
|
some compression opportunities. The added support for routing table manipulation |
||||
|
might increase comfort. Besides further honing existing features, this release |
||||
|
addresses some bugs. |
||||
|
|
||||
|
### New Features |
||||
|
|
||||
|
* Two lightweight stream ciphers: ChaCha20 (optional, through OpenSSL) & SPECK (integrated) |
||||
|
* Full Header Encryption (including packet checksumming as well as replay protection) |
||||
|
* A callback interface to better integrate n2n in third party software (you can still use it stand-alone) |
||||
|
* Enable the integrated LZO1x compression |
||||
|
* Add optional ZSTD compression (through zstdlib) |
||||
|
* Support for changing system routes at program start and end |
||||
|
* User and group id parameter for supernode |
||||
|
* Application of cryptography in n2n is seperately documented |
||||
|
* Add a new pseudo random number generator with higher periodicity seeded with more entropy if available |
||||
|
|
||||
|
### Improvements |
||||
|
|
||||
|
* Have AES and ChaCha20 use OpenSSL's `evp_*` interface to make better use of available hardware acceleration |
||||
|
* Fix invalid sendto when supernode name resolution fails |
||||
|
* Update to supernode's purge logic |
||||
|
* Extended management supernode's port output |
||||
|
* Fix read tap device failed when OS wakes up from sleep |
||||
|
* Free choice of supernode's management UDP port (for multiple supernodes on one machine) |
||||
|
* Additional trace messages to better indicate established connections and connection type |
||||
|
* Fix edge's register-to-supernode loop |
||||
|
* Remove redundant code |
||||
|
* Restructure the code in directories |
||||
|
* Clean-up platform-dependant code |
||||
|
* Compile fixes for Windows |
||||
|
* Fix build warnings |
||||
|
* …and many more under-the-hood fixes and tunings |
||||

of 2.4 that has been the first release since a long time of silence. |
||||
|
|
||||
|
### New Features |
||||
|
|
||||
|
* AES encryption that features an overall speed bump (12x speed) and security with respect to Twofish used in the previous n2n version |
||||
|
* Add ability to specify a whitelist of allowed communities on the supernode |
||||
|
* Implement local peers discovery via multicast |
||||
|
* Full peer-to-peer topology support. |
||||
|
* Add support for multiple edge systemd services |
||||
|
* Add benchmark tool for the encryption throughput |
||||
|
* Implement packet stats for P2P vs supernode communication |
||||
|
* Automatically drop privileges to user n2n |
||||
|
* Add support for ARM64 build |
||||
|
* More options to control MTU, P2P connections, TOS and log verbosity |
||||
|
* Implement a wireshark dissector for the n2n protocol |
||||
|
* Implement n2n-decode utility to decode and dump traffic to PCAP |
||||
|
|
||||
|
|
||||
|
### Improvements |
||||
|
* Extensive Windows and OpenWRT support. |
||||
|
* Windows compilation fixes and instructions |
||||
|
* Instructions and makefile file to build n2n on OpenWRT |
||||
|
* MacOS compilation fixes and instructions |
||||
|
* Improve the connection stability and the chances to establish a P2P connection |
||||
|
* Stable and more resilient connection. |
||||
|
* Remove keyschedule support to simplify the encryption code |
||||
|
* Replace peers linked list with hash table for faster lookup in big networks |
||||
|
* Integrate the changes made in the meyerd fork of n2n |
||||
|
* Remove calls to system() in tuntap_linux and use netlink instead |
||||
|
* n2n version improvements |
