MIGRATION NOTES

The resource pack (or your own version of it) is now very important!

Spells, wands and brooms won't look right, and most spell sound effects will not work without the resource pack.

4.0

• Many default spells migrated to the new "action" system.
• Default configs changed drastically, all auto-undo.
• Enchanting path options changed from max_xp_max and max_xp_regeneration to max_mana and max_mana_regeneration
• Commands in command spell parameters have changed slightly.
  (@t -> @tn, @p -> @pn for target and player names)

3.9.4

• All of the particle effect names have changed (internal EffectLib change).
  There is a PHP script available to help migrate custom configs.
• WorldGuard 6 or higher is now required for region support!

3.8

• The "enable_creative_mode_ejecting" in config.yml now controls the creative mode special
  behavior. If you have "enable_custom_item_hacks" set to false, you probably want to set
  enable_creative_mode_ejecting to false also.

3.7

• Some magic items (spells, upgrades) may need to be updated. Sorry!
• The "xp" casting cost has changed to "mana" ("xp" is still valid, but consumes player XP)
• If you have a completely custom spells.yml, search are replace "xp:" for "mana:" to fix.

3.6

• Drop support for Cratbukkit 1.6 - 1.7.2 is now the minimum required version
• Update to EffectLib 2.0 - all effect class names have changed

3.5

• The configuration option "wand_enchantable_item" is now off by default. This means
  that wands won't change to a wooden sword when enchanting. If you are using a pre-1.7.9
  version of Bukkit, you may (or may not) need to put this option back in config.yml

3.4

• The particle effect names have changed to the EffectLib versions is all places:

3.3

• Enchanting is now customizable via multiple enchanting paths. If you had previously modified the "random"
  template in wands.yml, you will need to transfer your work to enchanting.yml.
  There are also now multiple different enchanting paths, review wands.defaults.yml,
  you will need to override "path" for wands if you want them to continue to all use
  the same enchanting path (now called "master").

• Crafting is now customizable, there are several new recipes apart from the old
  blaze rod + nether star default. Please review crafting.defaults.yml and adjust
  accordingly, especially if you have a customized crafting configuration.
