It's been about 3½ months since stable branches of both projects were released (synchronously, in early January). Could be time within the next month or so for a new stable release. Is there anything you'd like to get in before then, or conversely any large changes that should wait until after?
I'm about to post a series adding a .cleanup callback (counterpart to .after_fork, and called in outer-to-inner order, opposite of .unload called in inner-to-outer order), in order to modify the ext2 filter to allow multiplexed connections.

For me, but none of them are urgent before this release:
Proposed nbdkit-forward-filter which ensures that we only do forward reads over the plugin.
nbdkit-readahead-filter fix/replacement. Requires background threads, this may be possible already.
Not easy without a .cleanup callback (it IS possible to create a background thread, but .unload is too late to clean that thread up gracefully to ensure we close the plugin's handle without accidentally calling into unloaded memory). -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
