This release adds fully transparent support for Bird 2.0 out of the same config tree. There's been a major reorg in filenames and directory structure - from now on, use the 'papageno' script in the root dir instead of running the scripts in bin/ directly. The current bird-2.0 structure assumes a single daemon for both IPv4 and IPv6, but separating those out in case you want separate daemons should be trivial. There is no option to select just a Bird 1.6 or Bird 2.0 config, as the extra overhead for doing both is minimal.
All 'static' configuration items now live in lib/, all info that gets pulled in plus all dynamic configs now live in data/.
This version also adds RPKI for both 1.6 and 2.0 daemons (based on TCP feeds for now), as well as configurable GTSM and BFD on a per-peer basis.
