Bukkit

Version 6: February 14, 2013 (The Hey, Thanks Moderators for Putting Up with My Rapid Revisions Edition)

• Compiled From: https://github.com/stendec/Abyss/tree/v6

Added

• Portals may be any dimensions and not simply square.
• Abyss can now load world scale and blacklist information from Multiverse.
• Emerald Block Portal Modifier, which uses Vault to interact with economy mods.
• Bottle 'o Enchanting Portal Modifier, which lets you make portals cost experience to use, or require a minimum experience level.
• require-square configuration option for enforcing portal square-ness, defaults to true.
• use-multiverse configuration option for enabling Multiverse support, defaults to true.
• slime-ball-strength configuration option for modifying slime ball strength, defaults to 1.0.

Fixed

• Portals now use SafeLocations, which can safely exist even when the world they're within isn't loaded.
• Exceptions during startup are now trapped, ensuring problems with the plugins file won't prevent the plugin from loading.
• use-static-effect actually does something now.

Version 5: February 13, 2013

Added

• Rails will now automatically connect to the edge of portals, making it easier to make compact rail systems using portals.
• smart-rails configuration option for enable new rail logic, defaults to true.

Fixed

• Configuration not saving new values into user's configuration files.
• Fixed the piston extend event not working properly with the corner-depth configuration option.

Version 4: February 12, 2013

Added

• Auto-updater that fetches the latest version from dev.bukkit.org.
• Update Command for manually starting an update.
• single-material configuration option for portal frames, defaults to false.
• corner-depth configuration option for portal frames, defaults to 2.
• frame-materials configuration option for portal frames. defaults to [occluding, ice]

Fixed

• Removed old, unused code from ABPortal.

I haven't had the opportunity to do any performance testing on large servers yet, and no long term testing for memory leaks and the such has been performed. Minimal testing seems fine though.

There's currently no way for a normal player to get a portal wand, though they can use wands after they've been given them.

Some commands error out if used on portals in unloaded worlds. This seems like it should be incredibly uncommon to come up though.
