Snabb 2018.04 “Edamame”
This release includes the newest version of Igalia’s lwAFTR, as well as a powerful new load testing tool. Also in the mix is an easy way to test Snabb on platforms that support Docker such as OS X, a new “unhexdump” tool that synthesizes packets from hexadecimal encodings, and significant performance and stability improvements. As usual, Edamame also includes assorted bug fixes.
