Supported Bukkit Versions
Support a hard-working dev! Please consider my other projects:
Phantom Admin - GriefPrevention Flags - AutomaticInventory - GraviTree - DiamondGuarantee
- Updated the API to support a new "NoExpiration" flag in GriefPreventionFlags.
DO NOT Update GriefPrevention to 11.3 or later until you've updated your server to the LATEST 1.8 (this will require re-running buildtools.jar to get an updated 1.8 server jar file). This is unavoidable, and due to a change made by the Spigot/CraftBukkit team somewhere along the way in 1.8 development. Symptoms of an outdated 1.8 server include errors logged during boot, explosions destroying blocks where they shouldn't, and entities like armor stands, item frames, and animals NOT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
- Claim Expiration - Version 13.6 and higher. Enabled claim expiration on all servers at 60 days of player inactivity (since last login), with the exception of claim owners who have a claim block total of at least 10,000, or a bonus claim block total of at least 5,000. All of this is configurable in config.yml.
- 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
- When loot dropped by players on death is protected from theft, it's now also invulnerable to damage (like dumping lava on it). Note that if an item is covered by lava even a little bit, the client will stop rendering it. But if you clean up the lava, you'll find your items are still there. Items will still disappear if left for too long.
- Fixed players placing hopper minecarts without permission.
- API updates to support GriefPrevention Flags.
- Performance boosts across the plugin.
- In creative worlds, limited number of "active" (lag-generating, like hoppers and beacons) blocks per land claim based on total claim area. Players with griefprevention.adminclaims permission ignore this limit, and already-placed blocks will not be removed retroactively.
- When admins use /softmute, that now also appears in the GP logs when "administrative activity" is enabled for those logs in your config file. Previously, this only appeared in your verbose server logs.
- Stopped other plugins accidentally breaking GP's anti-death-message-spam feature by setting the death message again after GP silenced it.
- Enabled claim expiration on all servers at 60 days of player inactivity (since last login), with the exception of claim owners who have a claim block total of at least 10,000, or a bonus claim block total of at least 5,000. All of this is configurable in config.yml.
- Performance tuned land claim expiration and then adjusted it to run checks more often, so expired land claims will be deleted closer to their expiration dates.
- Fixed TNT minecarts being placeable without /containertrust.
- Reduced the threshold for muting join/leave messages, to better combat bot spam which focuses on login/logout messages.
- Banned word list now applies to chat and whisper slash commands as well as standard chat.
- Fixed land claims to extending beyond the maximum claim depth (see your config file) in some situations.
- Fixed the automatic chat help (auto-help delivered based on a player's chat asking about land claiming).
- Automatic soft mutes (due to banned words.txt hits from brand new players) are now optionally included in GP's abridged logs under "admin activity". Muted messages due to /softmute can also be added to GP's abridged logs under new heading "muted messages".
- Fixed protected animals taking damage from explosive minecarts.
- Fixed killer bunnies being protected in land claims as if they were passive farm animals.
- Fixed errors in logs when using /claim in between the first and second right-clicks to create or resize a claim with the shovel.
- Gave /Claim an optional radius parameter.
- Fixed some minor issues with /Claim and chest-based land claim creation which were causing errors to appear in server logs.
- Fixed an issue with backward compatibility (for flat file mode claims) which should improve error messaging when there's a problem.
- Added /Claim command to create a land claim centered at the player's current location. If the player doesn't have any claims yet, this land claim will have the same size as an automatic chest-based land claim (radius modifiable in your config file). Land claims after the first require survival players to be holding the land claim modification tool (default golden shovel), keeping that "you gotta earn additional and larger land claims" concept alive. Additional land claims will appear as the smallest square which satisfies the minimum area you've set in your config file. Creative mode players always have access to the tool, so they don't have to hold one to prove it.
- Added /ExtendClaim command to change the size of a land claim or subdivision, especially handy for scenarios like claiming a mountain or extending a land claim into a solid wall as in an underground build, where getting into position to right-click a claim corner block is inconvenient. To use the command, stand in the claim you want to change, face the direction you want to change, and then specify the amount like /ExtendClaim 5 or /ExtendClaim -2. It even works with diagonals. Like the /Claim command, survival mode players will have to hold a golden shovel in hand to prove they have one before they can use this command.
- Added config options to ban players using a command line you specify, so GP can work better with any ban management plugin you have installed. By default, GP writes directly to the server ban list because that way it can record information about the ban like a reason (ex. spam) and a source (GriefPrevention) and show the banned player a message on the way out. The Vanilla /ban command only records a reason.
- To reduce invincible pets scattered about, administratively-deleted land claims (expirations or /DeleteClaim) will automatically set free any pets belonging to the owner of the land claim, allowing other players to tame or otherwise remove them without getting an administrator's help.
- Added permission griefprevention.eavesdropimmune to prevent a player (presumably an admin) from being eavesdropped upon by other admins. Now you can give a player permission to eavesdrop and still eavesdrop on him, whereas before everyone who could eavesdrop was immune to eavesdrop.
- Updated /RestoreNature with lots of new block types added in 1.8. Land restorations will leave less (hopefully zero) player construction behind.
- Equipping a golden shovel while you're standing inside a claim you own will automatically show you the boundaries of your claim, so you can skip the stick-right-click to find your corners.
- Improved claim management where water is involved - now much easier to create claims on water and resize claims when the corner to be adjusted is on water.
- Ensured players who place minecarts on another player's track can get their carts back by only allowing cart placement when the placer has permission to remove minecarts in that same location.
- Added a config option to tweak the delay between a new player joining and his receiving the land claiming manual.
- Whispers from admins can't be ignored.
- Fixed shift-click with stick finding too many claims.
- Improved logging for claim loading problems.
- Fixed blank lines in bad words file causing too many mutes.
- Now displaying player UUID in place of name when his name isn't in your local server data (instead of "someone").
- Fixed some servers losing subdivisions during upgrade.
- Disabled claim creation in worlds where claims will fail to load on next boot (worlds which are not yet loaded at the time GP booted).
- Stopped deleting claims from worlds which do not exist at the time GP boots.
- Messages.yml now supports formatting codes via the dollar sign ($). Find instructions at the top of your messages.yml.
- Added a config option to protect pets outside of land claims even in PvP worlds. Note that pet wolves are NEVER protected in PvP worlds because they have the potential to attack players, who should be able to defend themselves.
- Fixed ip re-use limiter being too aggressive.
- Added permission nodes for /Siege, /UnlockDrops, and /Trapped. All players have the new nodes by default.
- Soft-muted players can no longer send private messages to players who aren't soft-muted (see list of whisper commands in your config file).
- Soft-muted players can no longer use chat commands like /me to work around softmute (see list of chat commands in your config file).
- Made slash command lists for chat and whisper commands smarter - all aliases are now auto-detected so you don't have to tediously research and list every valid command variation. Or a translation - eliminated workarounds to get away with spam or dodge eavesdropping.
- Added a handy comment to the top of the config file, which provides a URL for the setup/config page.
- Added plenty of scary bugs to celebrate Halloween and GriefPrevention's version 13.0. ;) Yes, this is a joke. But seriously, did you know that since I started this project in 2011, GriefPrevention has released more than 200 versions, and has been downloaded about 350,000 times? O.o
- Made monitoring soft-muted messages easier. They will now appear in your server logs, and if you configure your abridged GP logs to include admin activity, they'll also appear there.
- Added an option (default off) to prevent rabbits eating crops.
- API: Added a public datastore method to get all the claims in a specified chunk.
- API: Made the shovel mode enum public.
- Added the griefprevention.seeinactivity permission node, which will show a claim owner's offline time when you inspect his claim with a stick.
- Allowed for adding a player to a personal ignore list while the ignored player is offline.
- Added PvP world options to disable flint/steel and dumping lava buckets near other players. By default the rules are off, so allowing PvP by build.
- Better new player detection for creative mode - this means players in creative mode severs with GP can use MineChat.
- Cleaned up the help experience around some claims-related slash commands.
- Fixed a free claim blocks exploit which was doable on servers where players can /sellclaimblocks.
- Fixed rare "data too long for column..." errors in database mode.
- Fixed hitting the concurrent database connections limit for servers who are online without a reboot for a very long time.
- Added support for empty banned words list (bannedwords.txt).
- Admins can't be ignored anymore - they have a new permission node "griefprevention.notignorable", which you can take away if you don't want players using /ignore to determine who has administrative permissions.
- Your basement and other underground structures will now be automatically protected by extending a new surface level land claim downward when you create a new claim, provided those structures are built with player block types and connected to other player-type blocks inside the initial land claim at surface level. In other words, fewer "I didn't realize my land claim didn't reach all the way to bedrock" complaints.
- Fixed the boot issue with database mode which appeared in 12.6.1.
- Improved database mode reliability after a period of server inactivity.
12.6 BETA Update
- Added auto-mute for chat trolls. Players who've very recently joined your server and spout profanity (see new bannedWords.txt file) will be automatically muted. They won't know they're muted, and an admin can undo the mute with /SoftMute.
- Added a lite profanity filter. If a player who isn't new to the server uses a word from bannedWords.txt, he'll get a warning and his message will not go out. Later uses of banned words from that player will be muted. Note that this banned words list does not support regular expressions by design - see the setup/config page for an explanation.
12.5 BETA Update
- In creative mode worlds, fluids won't flow outside of land claims.
- In creative mode worlds, several block types (cobble, obsidian, water source, lava source) won't form outside of land claims.
12.4.1 BETA Update
- No more attackers placing TNT in besieged land claims.
- Now cleaning-up any water above sea level in creative mode worlds when a land claim is removed.
- Fixed siege attackers having permission to toggle /ClaimExplosions.
- Fixed invincible attack dogs in pvp worlds labelled as non-pvp worlds in the GP config file.
12.4 BETA Update
- Performance boosts for creating, resizing, deleting, and managing permissions in land claims.
- Claim subdivisions (sub-claims) now have unique IDs.
- 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.
- 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.
- 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).
- Added a cancellable event to GriefPrevention's API so that other plugins may selectively disable the pvp protections.
- 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).
- 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. :)
- 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.
- When GP bans a player, there will now be notes in your ban file identifying GP as the source and listing a reason.
- Configuring a redstone comparator (default: right click) now require build permission inside land claims.
- Fixed log spam when claim block accrual rate is set to zero.
- Fixed /ContainerTrust not allowing farming in claim subdivisions.
