Release Notes: The main issue that this version fixes is a rather likely crash that could happen when interfaces were repeatedly brought down and then up. There are some minor tweaks to time handling that should prevent improper behaviour when the system clock is stepped on legacy platforms.
Release Notes: This version fixes some bugs and improves a number of heuristics to make Babel noticeably less chatty without increasing convergence time.
Release Notes: This version implements a new packet format (version 2) which is more robust, less chatty, and more flexible than version 1. It is incompatible with previous versions of Babel.
Release Notes: This release adds an interface for speaking to GUIs and minor tweaks to cost computation (including a fix for a fairly rare overflow).
Release Notes: This version fixes a rather unpleasant bug that could cause link quality to remain stuck at infinity under some circumstances. It also recovers faster when a neighbor has the bad taste to change its link-local address, and further improves scalability when redistributing massive amounts of external routes.
Release Notes: This version automatically notices when it is run over a bridged interface, and disables split horizon and other optimizations specific to wired links. If POSIX clocks are available, it will behave correctly when the real-time clock is stepped. The one remaining arbitrary limit, on the number of kernel routes, has been removed.
Release Notes: All data structures are now dynamically allocated, which removes any remaining artificial limits on Babel's capacity. Babel is now compatible with very recent Linux kernels (2.6.25 and upwards).
Release Notes: Route retractions are now sent multiple times, which speeds up convergence with heavy packet loss. There are minor tweaks to the request and update sending logic, which reduces the amount of routing traffic but doesn't affect convergence speed.
Release Notes: A number of small tweaks were made to the message sending strategy (triggered updates and unicast requests). A crash that would happen if an interface with large MTU was added at runtime was fixed.
Release Notes: This version allows automatic redistribution of local addresses, so there is no longer any need to specify them explicitly. Convergence speed has been vastly improved in some cases.
