There will be a patch later today including a new client and launcher/patcher. Installation should hopefully be transparent to you guys, you will use the existing patcher to download a small update which should hopefully (fingers crossed) run automatically and continue with the new patch.

Patchnotes:

New content
Nightfall Shelter is now open. This is a level 60-75 PK enabled map with normal and elite monsters that drop a full range of rare and unique items. Lost Mysterion decided to make this his new home.

Little Tiger and his friends can now be found roaming the Shadowfields, but don't be mistaken, this is no easy target! Defeat his small army and you will be rewarded well. There's a chance you will tame this beast and use him as your trusty steed as well!
(This encounter needs testing. I have absolutely no idea how it will pan out, how many players are needed etc so will be keeping a close eye on).

New items:
New relics are available from May for Scrub's Tears. These are expensive and should use up all those surplus tears you have all been hording.

Item changes:
The level 75 weapons from Mysterion/Cringer had their damage range increased.

Trader-70's Level 70 epic armor sets got a new look and the helm and chest received a chance effect bonus.

Trader-75's Level 75 epic armor sets received a chance effect bonus (Helm and Chest).
The 1 day mounts obtained from the Vortex have been fixed and will now expire after 1 day.

Removed the 100% HP pots from May, nice while it lasted eh? 50% and 30% are still available.

Dungeon changes:
The Vortex hard mode should now be a bit more challenging. HP of all of the monsters has been increased. The rewards have also been increased with more 1 day mounts, 3 day relics and other items.

Bosses in Laioha, Decomus and Wood Garden no longer drop boxes/chests and have acquired some new items.

Trash monsters in Wood Garden hard have a lower chance of dropping Mighty Trophies.

Gigantes in Decomus hard has a higher chance of dropping Mighty Trophies.

Quests:
You can now hand in those Corrupt Nightmare Souls you've been collecting from the Vortex. Rain will gladly exchange 100 Souls for an Emerald Nightmare permanent 50% speed mount.

Monster changes:
Certain monsters became a lot richer, notably Circus and World bosses, but changes were made to many more.

Colossus Shadowfield monsters now have a much higher chance of dropping rare, unique and epic items.

Ursadine monsters now drop rare and unique items, not just greens.

Mechanics changes:
Decomposing items is now much faster. 1 second cast down from 3 seconds.

Monster Transformation cards, potions, food, tarot cards, tears, trophies, coins all now stack much higher.

A,B,O,AB cards, wearing cards, spreads are now stackable, should save you some inventory space.

Massive overhaul of the loot system which is finally working properly so we no longer need the boxes/chests. I spent a lot of time manually changing the drop rates so there may well be some issues with drop chances on some items but I'm sure you guys will let me know about that. Overall the rates should be the same or higher than before EXCEPT in Wood Garden where things were dropping wayyyyyy to much since they were set to 150%!! To make up for it the bosses in there now drop some extra items which you can find on nsDB.

World drop chances of a lot of items have been doubled, including the epics from Night's Forest etc.
