New Quest: Kingdom of Aslona

A new main quest will see you trying to bring peace back to the kingdom of Aslona, currently in the middle of a civil war.
Add five new locations.
Player can now have a ship to sail the oceans of worldmap. This also means that they can now bring pets that would normally be unable to cross the ocean with them.
Moving over the ocean is slightly slower than on dry land.
Changes:

Added Aslona!
Added new ROOM_OWNED_AREA type for generic owned rooms. Uses code similar to the Cathedral or Decos' house.
Change structure of quests. Petrus now takes the encrypted scroll and gives you some alone time. If you chat with him again, you will receive the GC quest, or you can find other people to chat for other quests.
Add some new monsters, items, artifacts, materials and crafting recipes.
Hotness can now be used to define materials that deal fire damage on contact, just like Acidicity for acidic materials.
Use GitHub app for LGTM.
Cats can be tamed with fishes.
Orcs have black blood.
Lobh-se is a bit more fun.
Make amulets easily recognizable by color.
Land mines can now be sometimes defused if you levitate over and pick them up.
Willpower now protects against some hostile magic.
Add autopick regex.
Add an option to show info about gods, displaying their last reaction to prayer.
Better 'F1' command in menus:
Some items now have descriptions.
Better help for crafting actions.
New help for config options.
Add options to start with no pet and to use health descriptions.
Add alternate door traps.
Prevent very dumb creatures from using wands.
You cannot unequip locked chastity belt.
Update README and add MANUAL.
A wise player can look at an enemy for a rough estimation of their health.
Add day/night cycle to all above-ground locations.
Enable weather effects for more above-ground locations.
Let monsters also benefit from Detecting status effect.
Coffins now generate with grave goods and do something when you steal from them.
Hammers are good with the undead.
Some monsters now have different diets.
Add many new sound effects.
Fixes:

Decos no longer lets you steal from him.
You can no longer leave the Black Market through walls.
Slightly nerf Black Market.
Display Willpower in wizard mode secrets.
Running in wilderness now correctly takes stamina.
Fix some quest messages not being saved as already displayed.
Reveal gas traps when you step on them.
Fix several places where panic immunity or disease immunity was not respected.
Fix several crafting bugs, hopefully preventing crashes.
Fix Terra not offering priestly services after you killed Lobh-se.
Spill more water over a burning player when they pray to Silva, so there's a better chance to be extinguished.
Prevent long strings in config options from overflowing when displayed.
Prevent building features in owned rooms.
Explosive liquids can no longer be used to douse flames.
Wands of webbing were not causing hostility.
Fix horns of fear causing panic without checking the panic resistance of the victim.
Remove redundant messages from auto map notes.
Fix sitting on fountains and drinking from non-water fountains.
Fix AI not using equipped zappable items.
Make taming/possessing more powerful creatures scale correctly.
Fix a bug where boots were not correctly considered for kicking effects.
Fix teleport lock from non-equipment sources never timing out.
Assorted minor fixes and balancing.
See v057...v058 for a list of changes since 0.57

Iter Vehemens Ad Necem means something like 'The Violent Journey towards death' :P

O.K. so IVAN is the acronim for 'Iter Vehemens Ad Necem', but what does that actually mean please?.

Tarin:
Visit us at http://www.attnambananas.com (minus the bananas, for spambotty reasons), there's a forum out there, which is pretty much an "ultimate guide" :)

Cheers

PLEASE: some one do an ultamate guide,and post it on gamefaq.com, for as hard as this game is, it realy needsit. if you dont want to, ask your freinds too, or write GI,or gamewinners or some thing! but this games lived in obscurity for too long
