Bukkit

• Fixed error with explode spell
• Fixed combust doing insane damage
• Fixed haste spell not removing haste effect
• Fixed some default config issues
• Fixed small issue with alt-config
• Added enable-volatile-features option
• Added new multi-spell loading method (works like normal spells now)

Version 2.4:

• Added new spells: Invisibility, Materialize (example: water), Shadowstep, Projectile (example: explosivearrow)
• Added ignore-armor option to drainlife, geyser, and pain
• Added fire-tick-damage and prevent-immunity options to combust
• Added spellbook-block option for spellbook (will work with enchanting tables)
• Added experience option to all spells (casting spells will grant experience)
• Added execute-as-target-instead option to external command spell
• Added ignore-canceled option to explode spell (it will charge reagents and set cooldown even if the explosion is prevented by another plugin)
• The permissions magicspells.noreagents, magicspells.nocooldown, and magicspells.notarget will now obey the default-all-perms-false setting
• Some tweaks to the carpet spell (I hope I didn't break anything)
• This will be a bit annoying, and I apologize in advance, but it had to be done. Many spells previously marked as "instant" spells are now "targeted" spells instead. You will need to update the spell-class values for these spells. Spells affected: blink, build, combust, cripple, disarm, drainlife, entomb, explode, fireball, forcetoss, geyser, heal, lightning, pain, potion, telekinesis, volley, zap
• This version will break compatibility with the current version of MobArena (v0.94.3.24), however, it appears bleeding builds of MobArena should work fine

There is currently a bug with the explode spell, the prevent-block-damage and damage-multiplier options are not working. This will be fixed soon.
