Instances have since MoP (Possibly even Cataclysm) been able to set new locations for players when they zone into the instance.
A theoretic example of this could be after a certain boss has been defeated, a new entrance location is set to bring players entering the instance closer to the relevant content.
A real example would be Siege of Orgrimmar changing entrance locations many times as the raid progresses.
Added SetEntranceLocation for setting entrance locations that will be saved to DB the next time the instance is saved, and SetTemporaryEntranceLocation for when you don't want the value to be saved to the database.

Update SQL files should now be in a sub-folder equal to the current branch name
/sql/updates/auth/*.sql -> /sql/updates/auth/6.x/*.sql
/sql/updates/characters/*.sql -> /sql/updates/characters/6.x/*.sql
/sql/updates/hotfixes/*.sql -> /sql/hotfixes/world/6.x/*.sql
/sql/updates/world/*.sql -> /sql/updates/world/6.x/*.sql
This facilitates merges between the version branches
