From the Test Update Notes:

BANK

On all servers:
Banks how have four extra slots for a total of twelve bank slots per character.
Shared banks now have four extra slots for a total of eight shared bank slots per account.
Shared banks now allow you to share coin between characters on the same account.
Exiled characters continue to be unable to use shared banks with other characters on the same account.
On PVE servers:
Shared banks are now shared between good and evil characters on the same account.
If you have all four slots filled in both good and evil shared banks currently, they will be combined into a new eight slot shared bank.
Both coin and items can be shared with characters on the same account regardless of alignment.
On PVP servers:
Shared banks are still alignment based. However we have added four extra slots to each alignment's shared bank (for a total of eight shared bank slots per alignment) and the ability to share coin between characters of the same alignment on one account.



Also good to note:

ACHIEVEMENTS

You can now gain Achievement Experience from gray con quests that are level 10 or higher.
