12.4 Update

This build is BETA because the way claims are saved has changed. That means you should back up your griefpreventiondata folder (or your grief prevention database for database users) before upgrading. In the event you have some issue with your data, you can roll back to your backup data and also to the last non-beta version of GriefPrevention.

• Performance boosts for creating, resizing, deleting, and managing permissions in land claims.
• Claim subdivisions (sub-claims) now have unique IDs.

DO NOT Update GriefPrevention to 11.3 or later until you've updated your server to the LATEST 1.8.3 (this will require re-running buildtools.jar to get an updated 1.8.3 server jar file). This is unavoidable, and due to a change made by the Spigot/CraftBukkit team somewhere along the way in 1.8.3 development. Symptoms of an outdated 1.8.3 server include errors logged during boot, explosions destroying blocks where they shouldn't, and entities like armor stands, item frames, and animals NOT being protected.

Recent Major Changes

• Narrow land claims - Version 12.1 and higher. The config setting for minimum claim size (height and width) has been replaced with TWO settings - width and total area. These new settings default to 5 and 100 respectively, to allow for more narrow land claims, empowering players to more efficiently protect railways and roads, so they might actually do that now rather than rolling the dice and then complaining to admins when someone damages their roads. :)

• Selling accrued claim blocks - Version 11.0.2 and higher. If players sell accrued blocks, those blocks will NOT re-accrue over time.

• Nether portal protections disabled by default - Version 10.6 and higher. For sake of performance, the feature which prevents nether portals from being created in land claims without permission (by creating a nether portal at the corresponding coordinates in another dimension) is turned off by default. You can enable it in your config file. This "grief" is very difficult to execute, opportunities to attempt it are rare, and it's surprisingly expensive to prevent. Even when it works, the "victim" might actually be appreciative, since he didn't have a nether portal nearby already.

• PvP worlds reset - Version 10.4 and higher. This area of the config file has been frustrating for many for a long time. I've rewritten it to be more readable, much easier to edit, and now you can have an empty PvP worlds list on a PvP server, if that's what you want. When you update to this version, you will have to customize this part of the config file again (if you ever customized it at all).

• Finding offline players by name - Version 9.0 and higher. For sake of performance (not producing lag), players and admins can only target offline players who've recently logged in with Grief Prevention slash commands like /trust, /transferclaim, /claimslist, and so on. I plan to keep working on this to make all players targettable without causing a lag problem. This limit on who can be targetted is a temporary solution to work around a problem introduced by the CraftBukkit team when they made the switch to support player UUIDs.

• UUID Conversion - Version 8.1 and higher. During boot, an often very slow, one-time conversion process will replace player names in your data with player UUIDs. This process can take as long as one second for each player who has EVER played on your server. Make a backup before you upgrade, and please be patient. If this process is interrupted, you'll have to restore from backup and start over. This change will ensure players who change their names will not lose claim blocks or access to their land claims. If there's a problem, I need to know whether you're online/offline/bungee, whether in database or flat file mode, I need your boot logs from the conversion attempt, and if possible, a snapshot of your data from before the update.

• Disabled worlds in config - Version 8.5 and higher. If a world is "disabled" for land claims, then no land claims which already exist in that world (including administrative land claims) will be protected. For those upgrading from an earlier version ONLY, to ensure all existing land claims are protected, GP has defaulted worlds which were disabled to allow claims again, including player-made land claims. If this isn't what you want, update your config.yml.

• Piston limiting - Version 8.1.7 and higher. Pistons won't move blocks outside of land claims. This is a huge performance win, but if you want the old rules back, there's a new config option to disable this rule. Yes, players do get an explanation/warning when they place pistons outside of land claims, to avoid confusion for newly-placed pistons.

• /DeathBlow Removed - Version 9.3 and higher. It's no longer necessary, since the items players drop on death are now protected. This protection is on by default in non-PvP worlds, and off by default in PvP worlds. You may customize it in the config file. You can still use /kill to kill a player, although /kill will not send the player's inventory to another player as /deathblow did.

All Recent Changes

12.3 Update

• During a siege, attackers may now place TNT inside the defender's land claim and ignite it.
• During a siege, TNT will now destroy soft block types (see config).
• After a siege ends, during the period where the defender's doors are unlocked for looting purposes, attackers may now continue to break soft block types.

12.2 Update

• Squids are now protected in land claims.
• Added an administrative /ClaimBook command which gives a player a replacement claim information book.
• Fixed an intermittent problem saving player data.

12.1 Update

• Allowing narrow land claims (5 blocks wide). Introduced a minimum total area, default 100. If you previously customized the minimum claim size, you'll want to reconsider and adjust again since you now have two different settings to play with.
• Improved the repeat message anti-spam.
• Reduced the delay between a new player join and delivering a claim book to 10 seconds (from 30).
• API: Made GriefPrevention.lookupPlayerByName(string) public.
• API: Made player ignore lists public (see PlayerData.ignoredPlayers).

12.0 Update

• Added a cancellable event to GriefPrevention's API so that other plugins may selectively disable the pvp protections.

11.9 Updates

• Now giving new players GP reference books. This solves a few persistent problems. 1) players somtimes miss the in-context help messages, 2) players who watch the instructional video and play on non-default config servers get confused because the tools are not golden shovel and stick on their server, and 3) built-in command help is clunky. Yes, you can turn this off in your config BUT before you do, know that 1) only new players will get the books, 2) no player will ever receive more than one from the plugin, and 3) the books arrive about 30 seconds after joining, so they won't interfere with any on-join kits.
• Tweaked the portal trap fix's timing (10 seconds standing in a portal instead of 5).

11.8.1 Update

• In non-PvP worlds, players were successfully mounting tamed horses outside of land claims without permission, and placing fire and lava near other players. This is now fixed. :)

11.8 Updates

• Claim managers (/PermissionTrust) may now use /UnTrust again, but can't target other managers.
• In creative and survival-requiring-claims worlds, players may now create their first land claim using a chest like they would in Survival mode worlds.
• Reduced punishment for trying to chat an IP address that's not on the allow list (see config file for allow list) to message mute for first offenses.
• Now supporting an empty list of commands requiring access trust when used in land claims.
• In worlds where land claims are disabled, right-clicking with a stick doesn't prompt any messages now.
• Stopped eavesdropping private messages directed at players who have the eavesdrop permission.
• Added an API to determine whether or not a player is on the /softmute list.

11.7.5 Update

• When GP bans a player, there will now be notes in your ban file identifying GP as the source and listing a reason.

11.7.4 Update

• Configuring a redstone comparator (default: right click) now require build permission inside land claims.

11.7.3 Update

• Fixed log spam when claim block accrual rate is set to zero.

11.7.2 Update

• Fixed /ContainerTrust not allowing farming in claim subdivisions.

11.7.1 Update

• Fixed invincible guard dogs in PvP worlds.

11.7 Updates

• Added /AdminClaimsList.
• Fixed an easy workaround for the CAPS filter. Case-sensitive URLs may suffer, but are uncommon anyway.
• Fixed "in-pvp" status remaining after a player dies.
• Added smarts for dynamically generated/loaded worlds - PvP rules on/off will be determined by Bukkit's world.getPVP().
• Claim managers can't use /untrust anymore - because managers shouldn't be able to kick-out other managers.
• Visualizations play nicer with signs.
• Added a permission node for the /ignore commands - griefprevention.ignore.
• Claim files for non-existent worlds are deleted.

11.6.3 Update

• The "commands requiring access trust" config option now supports slash commands with specific parameters, like "/warp create".

11.6.2 Updates

• Once in PvP combat, a player can't just step over the line into a protected area when he starts losing the battle. Players who are in PvP aren't protected from PvP by land claims until they've gone 15 seconds without attacking or being attacked (default value - see PvP cooldown in your config file).
• Admins can use /ignoreclaims to attack players in land claims where they would otherwise be protected.
• Performance improvements for data storage.
• Fixed database migration (was briefly broken after the /ignore feature was added).

11.6.1 Updates

• No claiming land during PvP combat.
• Players offline for up to 90 days are now targetable with slash commands (was 30 days).
• To get sign notifications in-game (in the chat), use griefprevention.eavesdropsigns, instead of just griefprevention.eavesdrop (which still works for whispers).
• There's no more permission to automatically bypass pvp protections in land claims. Instead, use /ignoreclaims to toggle that bypass on and off.
• Output from /claimslist and /trustlist is now customizable in messages.yml.
• Stopped trying to auto-fill big holes in creative mode worlds. It was valuable when sea level is set correctly (see config file), but problematic when that setting is incorrect. I decided to make that trade-off.
• Better logging for secondary storage (file system or database) problems.

11.6 Updates

Added /ignore, so players can help themselves when there's no admin online to use /softmute and shut down a problematic chatter. Also helpful in reducing drama, which nobody likes. In addition to ignoring standard chat messages, an ignored player also can't use any whisper commands (see GP config file) targeting the player who's ignoring him.

Added /separate, an administrative command which forces two players to ignore each other. They are not notified, and can't see the force-ignored player on their /ignorelist. When two players can't get along but you don't want to totally /softmute either of them, this is a good option. Required permission: griefprevention.separate

11.5.2 Updates

• Disabling creature protections in the config file will now allow villagers to be attacked without permission inside land claims.
• Added a new config option so that server owners may allow anyone to trade with villagers, even in land claims where they have no permissions.
• Fixed sign placement entries in server logs not including the placing player's name.

11.5.1 Updates

• Added per-defender /siege cooldown.

• Performance boosts for equipping the golden shovel and delivering claim blocks.

11.5 Updates

• To combat using bots (or multiple accounts in general) to fill a server's slots so honest players can't connect, there's now a limit to how many players can connect at the same time using the same IP address. There are exceptions for players who have exhibited "human" behavior. :) You can change the limit in your config file, but I recommend giving the default a try first, since increasing the limit increases your vulnerability to this type of "attack".

• /AdjustBonusClaimBlocks (/acb) now works with player UUIDs.

• Removed formatters from the abbreviated logs for better readability.

• Improved sign formatting in abbreviated logs for better readability.

11.4 Updates

• Major new feature! Now server owners can quickly and conveniently review what happened during the time they were offline using GriefPrevention's new abridged logs. Unlike the noisy server logs, these logs are very selective about what they include and formatted for easy reading. They also automatically delete themselves after 7 days (default), and may optionally include GP administrative activity, like admins deleting land claims or giving players bonus claim blocks for example. Use this feature to make the most of other GP features like /softmute and suspicious bucket logging! :)

• Fixed explosion protection config settings. Now all permutations work - for example you could allow explosions only IN land claims, or only outside, or only outside below sea level, or everywhere or nowhere... and the /claimexplosions command will enable explosions for individual land claims temporarily.

11.3.2 Updates

• Added support for RoyalCommands plugin.
• Fixed /restorenature bugs associated with setting the sea level very low.

11.3.1 Updates

• Configuring GP to not protect horses now also stops them from being protected from damage in land claims.

11.3 Updates

DO NOT Update GriefPrevention to 11.3 or later until you've updated your server to the LATEST 1.8.3. If you do, explosion protection and other critical anti-grief features will NOT WORK. This is due to a change made by the Spigot/CraftBukkit team.

• Fixed standard explosions destroying blocks where they shouldn't in 1.8.3 servers.
• Fixed plugin-generated explosions (Essentials Protect, Extra Hard Mode, Cannons, etc) destroying blocks in 1.8.3 servers.
• Hoppy Easter! - Spawn eggs now require build permission in survival worlds (they already did in creative worlds).
• Hoppy Easter! - Dragon eggs now require build permission to teleport (left or right click).

11.2.2 Updates

• Fixed players selling spent claim blocks with /sellclaimblocks.

11.2.1 Updates

• Faster almost everything.
• Faster visualizations.
• Fixed PvP immune players being able to attack pets.
• /ClaimExplosions and the config option to enable explosion damage in all claims both override the sea level protections now. Exception: Still absolutely no explosion damage in creative mode worlds, where griefers have unlimited TNT.

11.1 Updates

• Fixed PvP rules applying in worlds NOT in the PvP worlds list.
• Added a config option to allow explosions to damage claimed blocks. The griefing potential is big - please don't enable this unless you have another plugin to limit the damage, like for example CreeperHeal.
• Better logging for blocked chat messages (the reason for the mute is recorded).
• Better sign notifications and logging.
• Signs with IP addresses not on the allowed list are now blocked.

11.0.2 Updates

• Fixed a bug which sometimes caused players to be unfairly punished for logging out on servers which use WorldGuard to limit PvP.
• Removed a debug log message (oops, how embarassing!).
• Fixed some clever players keeping PvP immunity while having inventory by receiving items via other plugins.

11.0.2 Updates

• When you have server economy integration enabled, players can't sell accrued blocks anymore, only bonus blocks. Also when they buy, those purchased blocks go into their bonus blocks.
• Fixed abandoning subdivisions penalizing blocks when optional abandon return ratio feature is enabled.
• Fixed ender pearl teleportation putting players into pvp combat mode.
• Reduced tolerance for IP address spam.

11.0 Updates

• Now "suspicious" water and lava bucket dumps will be logged (player name, fluid type, and coordinates).
• Villagers will now take damage from monsters, even in land claims (this was intended before, but a bug prevented it).
• Minor performance boost for visualizations.

10.9 Updates

• Eating cake now requires /containertrust or higher permission.
• Fixed a protection bug involving slime blocks.
• Made boot a lot faster for servers who have seen lots of players.

10.8 Updates

• Added a new claims mode you can use in your config file, "SurvivalRequiringClaims". This will work well for servers who have a separate resource world and want to limit their players to building only inside their land claims in other worlds, and very badly for other server types. This has some potential design problems (how do they get a golden shovel? What if they die and lose it?), which are yours to solve in the way you think best fits your server.
• Cancelled ender pearl teleportations won't consume the ender pearl anymore.
• /sethome now requires /accesstrust or higher permission. You may disable this or add more slash commands for this rule in the config file.
• Added griefprevention.siegeimmune permission to make a player immune to the /siege command.
• Added /setaccruedclaimblocks (/scb) to set accrued blocks to a specified value. They will auto-correct if you set them above the maximum you've set in your config file, or if you set them less than zero. /acb is still the best choice for almost all situations, but if you need this, now you have it.

10.7.1 Updates

• Fixed players selling their initial claim blocks.
• Perf boost for boot sequence (file and db modes).
• Bug fixes for /claimslist output.
• Tweaked spam filter tolerance for similar messages.
