Well, glancing through this thread, I feel like the odd one out, I only have a Heartbreaker in Zone ;( ...anyways, I heard that you wanted to be posted on iEra as well, and since its been 1000+ days, I have decided to give you some huge updates.
Shrekt won 2015 and 2016 GST.
The playerbase depleted a little bit (at least lately, it's been like 2.5k or so)
Chemical Guns are
no longer allowed in bases
Chemical Guns clear spar rooms nowadays

Obsidian has returned as of mid-late 2016.
Obsidian ended Grim Reapers in Tachi, Grim retired.
Arte playershops have changed to its original version, as a digging bus.
Spar hats and masks have been updated in regular spar and Multiplex.
iFreeze isn't a thing anymore.
The map is still pretty much the same, the playerbase is still the same (I think you'd understand what I meant, as well the majority of this thread)
Weapons were recently updated, retextured, nerfed, or boosted. 68+ guns were affected.
The server still lags even though it lost 1/6th of it's playerbase. :|
That's pretty much it for any updates that are new :/ nothing has really happened
(One last thing, gang rewards in iEra were extended to 50k hours being the highest, was formerly 15k, the new rewards you can get is new gun skins, custom melees, new gas masks, melee skins, grab hats and more hideout rooms.)
