1.0.1/2 Launch
If you study the list above you'll see theres been 20 updates since launch almost 4 yrs to the date of this post. 6 in 2013 , 10 in 2014 and just 2 in 2015 , that either states theres nothing more to update or they cant be arsed anymore . There hasnt been a bigger gap in updates as there was between 5.3.2 and 5.4.0 around 6 months . only a few months between 5.4.0 and 5.5.0 and since then its been approx three months . So i would guess somewhere in the next 3 months guageing from their history .. but that could and probably does mean sod all. this time of year seems to figure prominently in the history lol... maybe a xmas pressie from ninty...
so i think to satisfy your troll OP it will be on or around january 14th 2016. happy now ?
