KernelTrap has a summary up of recent HAMMER development, though if you’ve been reading here, it’ll already be familiar in a more truncated format.
Also! There’s a June 13th HAMMER update From Matthew Dillon, just to continue the trend. Recompile and re-newfs, as usual.
Following some of the article tags at KernelTrap creates an interesting topic-specific DragonFly history, incidentally.
