Best I can tell, the last AE2 commit for 1.8.9 was all of eight days ago.I seriously hope so, or something comes along that does what it used to do. Sorry, but I absolutely hate chests with a passion.
Interestingly (well, interesting to me, anyway) "Most of the 1.8 port" was committed by AlgorithymX2 himself ages ago. I'm sure there is still plenty to do on it, but it is by no means abandoned by its current custodians and will doubtless see the light of a 1.8.9 release.
And to keep the thread somewhat on topic, the current collection of mods are nowhere near mature enough for me to want to leap onto the 1.8 wagon just yet. But that's OK. I'm patient. Sometimes.
