Bukkit

1. PopDensity will now watch your number of players, and if the server empties, it will take advantage of that opportunity to scan resources without impacting players (still max once per six hours). Pretty smart, huh? =D

2. No more region notification messages (arrived, left) except for teleportations.

3. When build/break everywhere is enabled, players may only teleport from region post to region post. This means no more teleportation abuse to get out of the bad situations players put themselves in. You can still use the "teleport anywhere" config option to let players teleport from any location, if that's really what you want.

4. There's a new config option to disable scans while players are online entirely. Can be useful on servers with very few resources. However, it's possible that PopDensity could be waiting a VERY long time to get in a scan, especially when your server becomes popular and people are online 24/7. Therefore, you shouldn't turn on this option unless you also schedule a routine (daily, at least?) reboot. During boot, PopDensity will always take the opportunity to scan before players are allowed to join.
