Avalanche 4.44 released

A couple of weeks ago, version 4.44 of Avalanche was released. It’s not a major (4.x) release, but some new features made it (on top of bug fixes). Here they are:

  • TCP Selective ACK (SACK) is now a fully supported feature (it was an alpha feature before 4.44). This will help making the TCP behavior of Avalanche closer to modern Operating Systems (Windows Vista+, Linux Kernel 2.16+).
  • DHCPv6 client – that one should be self-explanatory.
  • More of Eliptic Curve ciphers. I’m really excited about those because, even if in the past we supported a bunch of them, they required DSA keys. The new ones support RSA keys, which are much more common. Some more ciphers were implemented, including the popular AES128-GCM-SHA256. Here’s the full list:
    • AES128-GCM-SHA256
    • AES256-GCM-SHA384
    • DHE-RSA-AES128-GCM-SHA256
    • DHE-RSA-AES256-GCM-SHA384
    • ECDHE-RSA-AES128-SHA256
    • ECDHE-RSA-AES256-SHA384

There’s also an exciting new Alpha feature: TCP Vegas! A lot of people were asking for this mode modern Congestion Avoidance mechanism.
