6.0 beta 2

Added an -e parameter to /rg flag that sets the flag to an empty value. You can use this to, for example, make it so the deny-message flag is empty, meaning that players won't get a message at all.
Added a visual smoke effect when an action on a block has been denied.
Added event-handling.interaction-whitelist, a list of items or blocks that should never be protected. For example, adding wooden_door to the list would make it so that doors could be used by anyone regardless if they have permission or not. You may still protect the blocks via other means.
Added event-handling.emit-block-use-at-feet, a list of items that, when used, will also be considered as the player using that item on the block at the player's feet. The purpose of this setting is, for example, to allow you to (sort of) prevent the use of a mod-added item that does not emit events.

6.0 beta 1

UUID support

Regions now fully support the use of UUIDs rather than names for storing the owners and members of a region. Commands still accept names, but they are translated into UUIDs in the background. For users who already have existing region data, names will be automatically converted to UUIDs on the first run of WorldGuard.

It is still possible to specify names rather than a UUID by using the -n flag with the region membership commands.

'Deny by default'

Previously, a pre-determined list of blocks and entities was used to determine whether an action by the player should be blocked. However, this has been reversed so that every action on a block or entity is denied (in a protected region) unless it has been deemed safe (such as, for example, right clicking with steak). Mods are now supported as a result.

The USE flag has been repurposed as a general "interaction" flag and covers every left click or right click of a block or entity. It also covers interaction that falls outside clicking.

Exhaustive protection

More events are now handled in the protection code. For example,

It is no longer possible to drop sand or gravel into a protected region from outside.
It is no longer possible to grief a region by growing a tree into it.
The entry and exit flags now handle players sitting on vehicles properly.
Piston-moved blocks cannot be pushed into a different protected region.
Owners of tamable animals are now considered in protection code.

Even water and lava flow can also be checked, although this requires that it be explicitly enabled in the configuration (flow events are very frequent, so they incur extra CPU cost).

The goal is to provide extremely exhaustive protection.

Large performance boost for spatial queries

The performance of spatial queries for regions has been substantially increased at least an order of magnitude. Spatial queries are a necessity for the region code to query the list of regions that apply to a location in the world. There should be a negligible difference between 4, 40, and 4000 regions as long as too many regions are not overlapping.

Background region operations

Region commands are now executed in the background. Notably, saves and loads will not lock up your server while they complete. Additionally, changes to regions are now saved periodically rather than immediately after every change.

Updated MySQL region support

MySQL support has been completely overhauled. It should now be faster, no longer crash on foreign key index errors, use transactions, and support automatic creation and migration of tables (including support for table prefixes).

Partial region data saving

For users of MySQL, WorldGuard now only saves changed and deleted regions when saving region data. No longer does WorldGuard have to rewrite the entire region database on each save.

Improved handling of related flags

Multiple flags that apply to an event are now evaluated together if they are similar. For example, if a player right clicks a bed to sleep in it, both the USE and SLEEP flag are checked since they are both interaction-related. If one of them is DENY, then sleeping is denied (remember, DENY overrides ALLOW). If one of them is ALLOW and the other is not DENY, then sleeping is permitted.

Only one "category" of flags needs to evaluate to true to permit an action. DENY will not cross categories. For example, if BUILD is deny, it will not override SLEEP, so if SLEEP is set to ALLOW, sleeping will be permitted. This is fairly similar to how it worked on WorldGuard 5.

Flag groups now work properly

While you could always set a group to a flag's value, the functionality was incomplete and did not work most of the time.

Now that groups are supported, you can change a flag so it only applies to a certain group of players. For example, /rg flag example sleep deny -g members would deny sleeping for only members of the example region.

Inheritance now works as expected

Previously, a region only inherited flags and other details from its parents if the parent and the child overlapped at the location queried. This is no longer the case and inheritance is now always applied.

In addition, a new -g flag for /rg define lets you create a region with no physical area so that you can assign flags and use this region as a "template region."

Settable deny message

It is now possible to change the message that users get when they are prevented from interacting with blocks or entities. This message is defined as a region flag, so you can set it on the __global__ region or override it in a specific region. In addition, the tone and color of the default message has been softened, but you are free to change it entirely.

Blacklist support for data values (and later, variants)

The blacklist was rewritten to support more than just block and item IDs. The immediate result is that you can now use data values, but as those are in the process of being deprecated by Mojang, it also allows support for Minecraft's new block variants in the future.

Debounced events

Events that tend to reoccur very frequently (such as the ones that occur when you stand on a pressure plate continuously) have been "debounced" to reduce the number of checks that WorldGuard has to perform, reducing the amount of wasted CPU. In addition, the "you don't have permission" message is rate limited so players are not flooded with the message.

New block place and break flags

A long requested feature was the availability of block place and break flags. These newly added flags work in tandem with the BUILD flag but can override BUILD. At the moment, it is not possible to allow explicit types of blocks to be placed or broken yet.

Build permission nodes

A new optional (disabled by default in the configuration) feature is the checking of build permission nodes. For every block, entity, and item, the following permission nodes are checked:

Block place: worldguard.build.block.place.<material>
Block break: worldguard.build.block.remove.<material>
Block interact: worldguard.build.block.interact.<material>
Entity spawn: worldguard.build.entity.place.<type>
Entity destroy: worldguard.build.entity.remove.<type>
Entity interact: worldguard.build.entity.interact.<type>
Entity damage: worldguard.build.entity.damage.<type>
Item use: worldguard.build.item.use.<material>

In addition, the permissions are also checked in the style of worldguard.build.block.<material>.<action>, so worldguard.build.block.<material>.place would work too.

The list of usable material names comes from the Material enumeration in Bukkit. For example, the permission for placing the bed block would be worldguard.build.build.place.bed_block. Be aware that Material contains both item and block names.

For entity names, see EntityType.

Other changes

Added a setting to permit "fake players" to bypass protection. Fake players are used by some servers and some mods to allow events to be thrown for mod blocks. WorldGuard considers a player to be a fake player if the name starts with [ and ends with ].
Added a check so players can no longer disembark in a region from their tamed animal if they don't have permission to get back on.
Added an item pickup flag to go along with the item drop flag.
Added a new //running command was added to show currently running background tasks.
Added a blacklist on-dispense event.
Added more detailed error messages when parsing the YAML regions file.
Added the -Dworldguard.debug.listener=true option that can be set on your server's command line to see how WorldGuard processes events, although this will result in a lot of log messages.
Added log messages that occur on player join when a player had auto-god mode or auto-amphibious mode.
Fixed the heal command so that it now sets a player's health to the maximum rather than 20.
Fixed ProtectedCuboidRegion.getPoints() returning points in wrong order.
Fixed the obsidian generator disable option to also apply to tripwire.
Fixed an error with the blocked commands flag.
Fixed a connection leak with the MySQL region code.
Fixed /wg reload sometimes not applying new changes right away.
Changed the region removal command so that child regions are no longer removed without warning when removing the parent region.
Changed the YAML region data save code to first write the data to a temporary file before replacing the final file.
Changed how region data is handled when region support is disabled: it is no longer loaded.
Changed sponges to now be disabled by default. However, if you had previously installed WorldGuard, sponges will still be enabled. Sponges are being added in Minecraft and they work differently than in Minecraft Classic (which WorldGuard emulates). In addition, enabling sponge support in WorldGuard incurs extra CPU cost even if no sponges exist in the world.
Changed how region data is loaded and saved so failures are now more graceful. If the region data fails to load for a world, then the entire world will be protected by default. In addition, periodic attempts will be made to load the region data in the background.
Changed the FEED flag to maximize the player's saturation level if the hunger level is raised.
Changed the wg-invincible and wg-amphibious groups feature so that it now must be enabled in the configuration.
Removed the ability for WorldGuard to upgrade from a version for Minecraft Alpha.

API changes

You can use a new WorldGuardPlugin.createProtectionQuery() method to easily check build permissions.
The listener classes were moved. Consider them internal -- if you want to make use of the listener somehow, please put in a ticket in our issue tracker.
Much of the protection-related handling was previously scattered throughout the code. Now WorldGuard funnels events into an internal event system and then processes protection queries in a more consistent matter. These events are for internal use so it is strongly recommended that you do not use them (they may change without notice drastically). A lot of the protection-related flag handling was moved there.
A significant portion of classes under the package of com.sk89q.worldguard.protection were changed or removed. However, the basic calls (testing the value of a flag, etc.) should still work, but they may be deprecated. Some of the utility Domain-related classes were removed.
The old region database (load/save) API was removed and replaced with a new one. The new one no longer needs to pointless store a collection of regions on itself -- it has collection = load() and save(collection) methods.
Previously, there were subclasses of RegionManager that implemented different spatial indices. However, now RegionManager is a final class and the spatial indices are separate (see the RegionIndex interface).
A hash table was implemented that caches a list of regions within each loaded chunk. This increases performance of spatial queries substantially.
A cache of recent spatial queries now exists (a cache of ApplicableRegionSets), but you need to make use of RegionQuery to make use of this cache. However, if you need to do a spatial query to modify region data, then the old method is better (get a RegionManager, etc.).
ApplicableRegionSet was converted into an interface. In addition, there are now "virtual" ApplicableRegionSet instances that are returned by RegionQuery for certain special cases (such as, for example, region support being disabled by the user or region data being unavailable for a world due to an error). A new isVirtual() method is available. This is not an issue if you are getting ApplicableRegionSet instances from a RegionManager.
ApplicableRegionSet now can accept a pre-sorted collection and its use of a TreeSet was removed for performance reasons.
FileNotFoundException is now properly handled in the YAML region file class. It creates the new file and continues on.
Player names are deprecated by Mojang and so they need to be converted into UUIDs. As this will take some time, you should do this conversion in a background task. To check whether a region contains a player, it recommended that contains(LocalPlayer) be used because it's possible that the user may be still using names. A new WorldGuardPlugin.wrapOfflinePlayer() method was added for this specific purposes.
All flags now use RegionGroup.ALL as the default region group.
StateFlag.getDefault() now returns a State rather than a boolean.
The priority R-tree index now uses the R-tree for region intersection queries. Previously, it was only used for single point containment queries.
Regions now keep a "dirty" flag and changes it whenever data within the region is changed. When WorldGuard decides to periodically save region data, it may only save changed regions. Calling save() on the RegionManager is no longer needed as periodical saves happen automatically.
The old region data migration API was removed in favor of region store drivers. There is no longer a need to have an implementation for every possible conversion (i.e. YAML -> MySQL, MySQL -> YAML, etc.).
ProtectedRegion.copyFrom() was added to copy region settings from another region.
@Nullable annotations were added throughout the code. If you use IntelliJ IDEA, you may notice that it now warns you when a return value may be null.

5.8

BREAKING CHANGE: This version has been built for versions of Bukkit for MC 1.6.1 and newer. Do not try to use this version of WG on an older Bukkit version.
Added support for Minecraft 1.6+. Actual support of new 1.6 additions is dependant on Bukkit. Please use a newer build of Bukkit if, for example, you seem to be unable to add "Horses" to your lists of entities.
Added mobs.disable-snowman-trails to disable the trails left by walking snowmen.
Added -a flag to /region removeowner and /region removemember to remove all objects.
Teleporting is now handled by entry/exit flags. If this is causing people to get entirely stuck inside entry/exit deny regions, set the new setting 'use-player-teleports' to 'false' in your configuration.
Updated formatting for region commands, especially /region info.
Changed permissions checking for /region commands to be more consistent, checking for region IDs as a sub-node. This means that if some permissions for some region commands no longer work, add '.*' to the end of permission lines for WG in your permission plugin.

Updated for v0.2.8.

Removed the block lag fix.

Changed some configuration defaults: disable-lava-fire=true simulate-sponge=true item-durability=false

1.4.1

Fixed issue with the block lag fix dropping item stacks of 0 quantity.

1.4

New on-acquire hook. This does both a total inventory check on inventory change and item pick up denial. The item pick up denial is largely thanks to Dinnerbone for fulfilling my request to add a particular hook.
Item durability can now be toggled with item-durability. Thanks to Dinnerbone for figuring this out while filfilling my request. The default setting is to fix item durability.
New no-physics-gravel and no-physics-sand options allow you to prevent gravel and sand from falling.
New allow-portal-anywhere option allows you to create portal blocks anywhere.

1.3

UPGRADE WARNING: If you are using database logging, you must add a NULL 'comment' VARCHAR field to the table. The line of SQL that you can run for MySQL can be found in blacklist_table.sql.
Improved plugin compatibility with the block lag fix. For maximum compatibility, you must now list WorldGuard as the first plugin in server.properties and you cannot reload or enable the plugin while the server is up. This is for bad plugins that unnecessarily use the "critical" priority for its hooks like the LWC. Most plugins don't do that though, so this won't apply for most people.
Fixed signs being blank if they were denied via the blacklist.
Added on-break event to the blacklist.
Added comments and messages. Comments are only for your own use and they are printed with the log and notify actions of the blacklist. The message replaces the message that is shown the user and it is optional.
The blacklist notification messages are now more compact and are light grey instead of light purple.
The notify, log, and tell actions will now trigger every time for the on-break, on-create, on-drop events rather than wait 3 seconds between events for the same item or block for a player.

1.2

/stopfire and /allowfire disable and enable fire spreading globally.
Block lag fix slightly improved in accuracy for item drops.
Sponge updated to remove water when the sponge block is set. Sponge radius can now be controlled using the 'sponge-radius' parameter and the default is now set to simulate Classic.
Updated for a newer build of "b126," meaning that lava spread control now works well!
A new summary of the status of some core protections is now printed on start. Disable this with 'summary-on-start'.
Blacklist system has been overhauled. Check README.txt for changed configuration settings!
The blacklist's method of preventing notification repeats is now better, instead waiting 3 seconds before notifying again (before it didn't notify again at all unless the user started using another blocked action).
To give users the ability to receive notifications, the command to give permission to has been changed to /worldguardnotify, although the old one (that was never mentioned anywhere) still works.
Water and lava buckets are now psuedo-blocked using an unreliable method that risks the stability of your server (no other plugin does it better though). Use it as your own risk.
Added on item drop and on item use (i.e. chest) events.
Chests, signs, and furnaces can now be blocked better with the blacklist system.
The event names in the blacklist configuration have changed but the old event names should still work. The new names should make "more sense."
A new "ban" action has been added to the blacklist.
Action messages have been improved, now longer saying "destroyed" for everything.
Logging to file has been completely changed, allowing you to use the date and time and the player's username in the log filename. It no longer rotates log files based on size, however.
Logging to database is now supported.
Tools can now be destroyed on drop to alleviate the durability cheat. You can do this with either with the blacklist or with the 'item-drop-blacklist' configuration option. The configuration option prints more friendly messages than the 'tell' action of blacklists.

1.1.2

Block lag fix: Snow and glass should no longer drop items.
Block lag fix: Block object now reset after hook call.

1.1.1

Fixed redstone wire dropping wood blocks with the block lag fix.
The block lag fix now consults other plugins so that ALL protection mechanisms and plugins should work.

Added block lag fix.
