Compatibility notes:

If you're on 1.2.3-R0.1, ocelot and iron golem spawners should now be available, using the default configuration (delete config.yml to regenerate).

If you're on 1.1-R8, the default configuration will also work as before.

If you're still on 1.1-R4, you _must_ set useExtraMobs: true in config.yml and remove or comment out any unavailable mobs.

There have been reports of duping spawners in protected territory (not new to 1.1a). I haven't been able to reproduce the problem and am looking for more information to investigate this issue. If you see this problem please add any information on your configuration to http://dev.bukkit.org/server-mods/silkspawners/tickets/2-silk-spawners-still-duplicates-broken-mined-spa/ - thanks
