Bukkit

IMPORTANT NOTE: If you're coming to 1.6.0 from 1.5.1, you should also read the changes for version 1.5.9 beta. PERMISSIONS HAVE COMPLETELY CHANGED.

• New command /f permanentpower to set a permanent power level for any specified faction; usage requires the factions.setpermanentpower permission (Olof)
• /f claim and /f autoclaim now accept an optional faction specification, to claim land for a faction other than your own (possible with admin bypass mode) (Olof)
• Safe Zones and War Zones are now called "SafeZone" and "WarZone" with the space removed, to fit with faction naming policies, and for the reason below (Olof)
• Commands removed: /f safeclaim, /f warclaim, /f autosafe, and /f autowar. You now use /f claim and /f autoclaim instead (Olof)

• Players with admin bypass mode enabled can now join any faction without invitation and claim land without needing to be faction moderator/admin (Olof)
• Additional event logging to server console/log, with new conf.json settings to enable/disable logging of specific events (Brettflan)
• Fix for /f permanent and /f peaceful commands giving an NPE if run from console (Brettflan)
• Fix for rare NPE when Spout territory info update is run and affected player disconnects at precisely that moment (Brettflan)
• Various other minor fixes from 1.5.9 beta

Changed commands:
/f claim [faction=yours] - claim the land you're standing on for your faction, or for another faction if one is specified
/f autoclaim [faction=yours] - start autoclaiming land for your faction as you walk around, or for another faction if one is specified
New command:
/f permanentpower <faction> [power=reset] - set a permanent power level for the specified faction (or unset permanent power if no power is specified)

New permission node:
factions.setpermanentpower - allows a player to use the /f permanentpower command

New options in conf.json:
"colorPeaceful": GOLD, - the color used to denote peaceful factions and safe zones
"colorWar": DARK_RED, - the color used to denote war zones
"logFactionCreate": true, - log faction creation
"logFactionDisband": true, - log factions being disbanded, by command or by circumstance (no players left in faction, etc.)
"logFactionJoin": true, - log player joining a faction
"logFactionKick": true, - log player being kicked from a faction
"logFactionLeave": true, - log player leaving a faction
"logLandClaims": true, - log land being claimed (including safe zone and war zone)
"logLandUnclaims": true, - log land being unclaimed (including safe zone and war zone)
"logMoneyTransactions": true, - log money being deposited, withdrawn, and otherwise transferred in relation to faction banks

Note for other plugins which hook into Factions API methods: methods in the "com.massivecraft.factions.Factions" class and references to the plugin singleton as "Factions.instance" have been moved to the "com.massivecraft.factions.P" class and "P.p" respectively as of 1.5.9. Apologies, it was necessary due to how the plugin has been restructured.
