Here's what's new, in no particular
order:

1) - Exp meter: move your mouse over a skill and it shows the number of points you have as compared to the number you need to level.
2) - Additions to ghost town: There is now a branch of the bank of Varrock in the ghost town as well as a general store.
3) - There's a new house between ghost town and the monastery, with an old man named Oziach inside. He only talks about what a fine day it is right now, but my suspicion would be that he is somehow involved in the upcoming dragon quest.
4) - Wilderness: The most massive part of the update, my personal estimate would be that this roughly doubles the size of the map... As you enter for the first time, a warning is displayed describing the dangerous nature of the wilderness. In the bottom right, as shown in the RS.com screenshots, a skull is displayed to indicate being in the wilderness and a possible target for PKing. Beneath it, the level of the wilderness that you are in is displayed. As you progress northward, the level goes up. The very end of the wilderness is lvl
48.

NOTE: The level indicator in the bottom right tells you the level difference that you can fight with (i.e. if you're lvl 43 and you're at lvl-16 of the wilderness, you could attack a lvl-27 player, or be attacked by a lvl-59 player).

In the wilderness, there are a variety of new things.

I've seen two new creatures so far: Chaos Dwarf (lvl-59) and Greater Demon (lvl-87). Some new things to look at are giant bones from dead animals, fungus on the ground, broken furniture, and half-burned houses.

All throughout the map, various treasure are scattered, from body runes and little piles of coins to earth staffs and various and sundry new runes. I was able to explore a portion of the right-hand side of the map before I was attacked by a chaos dwarf and forced to
teleport out (this answers a question running rampant on the boards: you CAN teleport out of the wilderness).

I got further the next time, to the very end, where I was PKed by a high-level player. I kept my 3 best items, as is standard when you die in the game (that answered another nagging question on the boards - you hold onto your stuff as normal). However, I don't know if people with skulls over their head lose all items when killed. The "skull-over-head" system is still in place for sure, though, because i saw people with this marking... Although I haven't visited the left side of the wilderness yet, I"m told there is an ice giant mountain there... On an unrelated note, someone claims
to have seen Andrew and that he is lvl-103....

- There's at least one graveyard in the wilderness. Finding a plank and using it with a grave allows you to rob it.
Take note that this is second-hand info, however. I didn't see this myself, I was told by a friend...

Hi, Lotta Might here:

I have take some time and noted the experience values for each ore. I believe there's still a bug about this, as it wouldn't show the pts. gained until I logged out and back in again. Perhaps in a future bug fix, we can see our exp. levels grow as we pick.

Anyways, I have listed all the ores, starting with least to most, experience points given. All, except for runite. :(

clay = 5 pts.
copper = 17 pts.
tin = 18 pts.
iron = 35 pts.
silver = 40 pts.
coal = 50 pts.
gold = 65 pts.
mithril = 80 pts.
adamantite = 95 pts.
