While it took a decade for E17 to bake, we've been expecting E18 to come about one year later and it's looking like it should happen.
Enlightenment E18 advances the Wayland support to ultimately provide full Wayland support but it won't be until E19 where Enlightenment can act as a Wayland compositor.
There were E18 Wayland changes in September as the last time I wrote about the release, but now the E18 Alpha release is being prepared. Enlightenment's Elementary was just prepared for an Alpha 1 release and the Enlightenment requirements were bumped for requiring EFL 1.8 for this upcoming release.
Among recent Enlightenment work has been lots of bug-fixing, shaped window mouse input, UDisks 2 support, compositor integration improvements, canvas merging. and new forms of eye candy.
