The banner at the top of the RuneScape website changes between day and night settings at specific times of the day.
The once slippery stairs in the Ancient Cavern now allows access to a new room with three metallic dragon heads and 10 anvils, also the mithril door can now be tried to be opened but the player will be pushed out again before entering. (The area with the metallic dragon heads is now confirmed as the Dragon forge as of the release of the While Guthix Sleeps quest.)
The run energy meter on the left of the minimap is made so that it can be toggled "On" or "Off" by clicking on the icon. It turns a bright yellow/gold colour when toggled "On". In addition, the following were mentioned on the forums by Mod Osborne, in reference to The Great Orb Project:
Players are now able to sign up for the activity with any of the wizard apprentices.
Players can now sign up to whichever team currently has the least players.
If a game lacks enough players, it will instantly finish.
Reward tokens are given whether players win, lose, or draw, based upon how well they've done.
A number of useful phrases has been added to Quick Chat for this activity.
Restoring the life points, Prayer, and Energy to full when players brought an offending item, entered the wrong crater, or entered in a different world in Bounty Hunter is fixed. To restore the levels, players must enter the crater suitable for their level.
Almost every emote with a glitch are fixed, including the infamous Bounty Hunter Skull glitch.
