L_Ender's Cataclysm in All the Mods 10

L_Ender's Cataclysm is all about difficult dungeons, challenging boss fights and powerful items. The deal is simple: you track down a boss, beat it in battle to prove yourself, and walk away with some seriously strong gear. If you like a real challenge in your modded playthrough, this is the mod for you.^[1]

All the Mods 10 8.1 ships version 3.33 of the mod, and it has been in the pack since version 2.25 or earlier.^[2]

Finding the bosses

The pack's Cataclysm quest chapter points you to each boss with a set of Eye items. Each Eye leads you to a structure where a big fight is waiting:^[3]

• Eye of Mech leads to the Ancient Factory and The Harbinger.^[3]
• Eye of Flame leads to the Burning Arena and the Ignis.^[3]
• Eye of Void leads to the Ruined Citadel and the Ender Guardian.^[3]
• Eye of Monstrous leads to the Soul Blacksmith and the Netherite Monstrosity.^[3]
• Eye of Abyss leads to the Sunken City and the Leviathan.^[3]
• Eye of Desert leads to the Cursed Pyramid and the Ancient Remnant.^[3]
• Eye of Curse leads to the Frosted Prison and the Maledictus.^[3]
• Eye of Storm leads to the Acropolis and Scylla.^[3]

Not every structure is a full boss arena. Newer updates added smaller, slightly less dangerous structures tied to the Cursed Pyramid and Frosted Prison. They hold accessories you can only find there, and some of them need the Belt of Beginner before you can equip them.^[3]

Cataclysm and the ATM Star

If you're going for the ATM Star, you can't skip this mod. The Chapter 3 ATM Star quests ask for these Cataclysm items:^[4]

• "Abyssal Sacrifice" quest: the quest calls this the easiest Cataclysm item on the path. You craft it from vanilla items and mob drops instead of getting it from a boss kill.^[4]
• "Meat Shredder" quest: this depends on Witherite from The Harbinger. You find The Harbinger powered down deep underground in the Ancient Factory, and you power it up by feeding it a Nether Star. Then you face a very difficult and long fight.^[4]
• "Void Forge" quest: this is the hardest one. It means taking down 2 bosses and a miniboss: The Harbinger, the Netherite Monstrosity in the Nether's Soul Blacksmith, and the Ender Golem in the End's Ruined Citadel.^[4]

L_Ender's Cataclysm adds difficult dungeons, challenging boss fights and powerful items. Your early game is about gearing up, finding the bosses' structures and beating them for their gear.^[1]

Step 1: Craft a Belt of Beginner

Start with a Belt of Beginner. Cataclysm now has smaller, slightly less dangerous structures related to the Cursed Pyramid and the Frosted Prison, and they hold accessories that only spawn there. Some of those accessories go in normal accessory slots, but others need you to wear this Belt before you can equip them. The pack changed the Belt's recipe, so use the version below. The Belt is also the task for the "New Accessories" quest quest.^[3][5]

Step 2: Craft an Eye to find a boss

Each boss has its own structure, and the Eyes take you there. Craft the Eye for the boss you want to fight and it will lead you to that boss's home. Here's where each one goes:^[3]

• Eye of Mech takes you to the Ancient Factory to fight The Harbinger.^[3]
• Eye of Flame takes you to the Burning Arena to fight the Ignis.^[3]
• Eye of Void takes you to the Ruined Citadel to fight the Ender Guardian.^[3]
• Eye of Monstrous takes you to the Soul BlackSmith to fight the Netherite Monstrosity.^[3]
• Eye of Abyss takes you to the Sunken City to fight the Leviathan.^[3]
• Eye of Desert takes you to the Cursed Pyramid to fight the Ancient Remnant.^[3]
• Eye of Curse leads you to the Frosted Prison to fight the Maledictus.^[3]
• Eye of Storm takes you to the Acropolis to fight Scylla.^[3]

Step 3: Prepare the summoning item

Reaching the arena isn't always enough. Several bosses need a specific item or step before the fight starts, so sort these out before you head over.^[3]

• Ignis: first fight the Ignited Revenant to get Burning Ashes, then use them on the Altar of Fire to summon the Ignis.^[3]
• Ancient Remnant: bring a Brush. The giant shaft down to the Remnant has 3 side rooms, and 2 of them contain Suspicious Sand that can give you the Necklace of the desert. Right-click the Remnant with the Necklace to resurrect it.^[3]
• Leviathan: you need an Abyssal Sacrifice. It has two recipe versions, and the pack changed both.^[3][5]
• Maledictus: the Door of Seal blocks the way, and you need a Strange Key to open it. The Aptrgangr in the Frosted Prison carry the key.^[3]

Early gear worth picking up

The Unbreakable Skull is very helpful against bosses. Some hits stun you, so you can't move or fight back, and the Skull protects you from that once per cooldown. In the quest book it comes after the Occupied Village, Desert Temple and Desert Site.^[3]

Koboletons drop the Khopesh. It does the same damage as an Iron Sword, but you can't enchant or repair it, so treat it as a stopgap.^[3]

Bone Reptile Armor gives very good stats for cheap armor, though it doesn't appear to do anything special. It's made from Koboleton Bones and Ancient Metal, and the Helmet also needs a Kobolediator Skull.^[3]

Unverified The sources don't say which boss is easiest or what order to fight them in, so pick your first target based on how well geared you feel.

L_Ender's Cataclysm is built around difficult dungeons, challenging boss fights and the powerful gear you earn by beating them. The core loop is simple: find a structure, trigger its boss, win the fight and use the loot. This section covers how that loop works and how All the Mods 10 has tuned it.^[1]

Unverified None of the available sources describe machines, multiblocks, power, fluid handling or automation for this mod. If Cataclysm has any of these systems, they can't be confirmed here, so plan around its bosses and gear rather than tech.

Structures and how bosses start

The mod's advancements point you to its main structures: the Ancient Factory, the Burning Arena, the Cursed Pyramid, the Ruined Citadel, the Frosted Prison and the Sunken City. Each one is tracked separately. Beating every boss unlocks the final advancement, "You have reached the summit of Cataclysm!"^[6]

Bosses don't all start the same way. The advancements say you summon the Ignis, the Leviathan and Maledictus, while you wake the Harbinger. To wake the Ancient Remnant, you excavate the suspicious sand inside the Cursed Pyramid.^[6]

Some key items tie into these fights. You can craft Eye of Abyss yourself. All the Mods 10 changed both recipes for Abyssal Sacrifice: one uses Crystallized Coral and the other uses Coral Chunk. Use the recipes below instead of relying on older guides.^[5]

Unverified The sources don't say which boss the Eye of Abyss or the Abyssal Sacrifice is used for, or how to use them.

How All the Mods 10 scales the fights

This is the big one: in this pack, Cataclysm mobs are much tougher than the mod's defaults. Each mob has a health multiplier and an attack multiplier, and both default to 1. All the Mods 10 raised both of them for every mob shown in the pack's config.^[7]

• Ender Guardian: health multiplier 20 and attack multiplier 8, set by mobs.ender_guardian.combat_config.health_multiplier and mobs.ender_guardian.combat_config.attack_multiplier.^[7]
• Harbinger: health multiplier 12 and attack multiplier 8, set by mobs.harbinger.combat_config.health_multiplier and mobs.harbinger.combat_config.attack_multiplier.^[7]
• Ancient Remnant: health multiplier 6 and attack multiplier 6, set by mobs.ancient_remnant.combat_config.health_multiplier and mobs.ancient_remnant.combat_config.attack_multiplier.^[7]
• Ender Golem: health multiplier 20 and attack multiplier 6, set by mobs.ender_golem.combat_config.health_multiplier and mobs.ender_golem.combat_config.attack_multiplier.^[7]
• Clawdian: health multiplier 10 and attack multiplier 9, set by mobs.clawdian.combat_config.health_multiplier and mobs.clawdian.combat_config.attack_multiplier.^[7]
• Baby Leviathan: health multiplier 10 and attack multiplier 8, set by mobs.baby_leviathan.combat_config.health_multiplier and mobs.baby_leviathan.combat_config.attack_multiplier.^[7]
• Amethyst Crab: health multiplier 6 and attack multiplier 8. Aptrgangr: health multiplier 3 and attack multiplier 8.^[7]

Several special attacks also hit harder in this pack. The Harbinger's death laser does 10 damage instead of the default 5. The Ancient Remnant's desert stele does 24 instead of 11, and its earthquake does 15 instead of 11. The Ender Guardian's and Ender Golem's void runes both do 10, up from 9 and 7. The Amethyst Crab's clusters do 16 instead of 12, and its earthquake does 12 instead of 5.^[7]

Some bosses also have health-based damage values, set on a scale from 0.0 to 1.0, and the pack raised these too. The Harbinger's death laser HP damage went from 0.05 to 0.1. The Ancient Remnant's HP damage went from 0.05 to 0.1, its charge from 0.1 to 0.2, and its stomp from 0.03 to 0.038.^[7]

Damage caps, range caps and healing

Some bosses have a damage cap and a DPS cap in the config, and All the Mods 10 raised them a lot. The Harbinger's caps are 50 and 45 (defaults 22 and 14). The Ender Guardian's are 70 and 41.4 (defaults 22 and 13). The Clawdian's are 210 and 120 (defaults 21 and 12).^[7]

Unverified The config only labels these values as "Damage Cap" and "Dps Cap". The sources don't confirm whether they limit the damage you deal to the boss or the damage the boss deals.

Range caps are higher too: 64 for the Harbinger (default 35), 32 for the Clawdian (default 12), 28 for the Ancient Remnant (default 14) and 24 for the Ender Golem (default 8).^[7]

Healing values changed in both directions. The Harbinger's auto heal is 8 instead of 2, set by mobs.harbinger.harbinger_auto_heal. The Ender Guardian's nature heal went up to 30 from 25. The Ancient Remnant's nature heal went down, to 20 from 25.^[7]

Outside of mobs, the Cursed Tombstone's cooldown is 15 in this pack instead of the default 1, within an allowed range of 0 to 30. It's set by blocks.cursed_tombstone.cursed_tombstone_cooldown.^[7]

Gear with active abilities

Much of Cataclysm's gear has active abilities, not just stats. For example, Astrape shoots a Lightning Spear when you right-click, and Ancient Spear shoots a Sandstorm when you left-click. Hold Shift over an item to see its details.^[6]

Progression in L_Ender's Cataclysm is all about bosses. You craft an Eye, follow it to a structure, defeat the boss, and use its drops to build gear. The pack's Cataclysm quest chapter follows that loop, and the in-pack recipes show exactly what each tier costs.^[3][5]

Early game: small structures and accessories

Before you face a full boss, you can explore the smaller Cataclysm structures. The quest chapter says these currently come from the Cursed Pyramid and Frosted Prison, and they hold accessories that only spawn there. Some of these accessories need the Belt of Beginner before you can equip them, so craft one early. The pack changed its recipe, so check the version below.^[3][5]

• Unbreakable Skull and Vitality Ankh come after the Occupied Village, Desert Temple and Desert Site quests. The Skull protects you from boss stuns once per cooldown, so it's worth having before the big fights.^[3]

Step 1: Craft the Eyes

Each boss has its own Eye, and every Eye has a quest in the chapter. Here's where each one takes you:^[3]

• Eye of Mech leads to the Ancient Factory and The Harbinger.^[3]
• Eye of Flame leads to the Burning Arena and the Ignis.^[3]
• Eye of Void leads to the Ruined Citadel and the Ender Guardian.^[3]
• Eye of Monstrous leads to the Soul BlackSmith and the Netherite Monstrosity.^[3]
• Eye of Abyss leads to the Sunken City and the Leviathan.^[3]
• Eye of Desert leads to the Cursed Pyramid and the Ancient Remnant.^[3]
• Eye of Curse leads to the Frosted Prison and the Maledictus.^[3]

Step 2: Unlock the summons

Some bosses won't fight you until you bring the right item. For the Ignis, beat the Ignited Revenant first, then use Burning Ashes on the Altar of Fire. For the Ancient Remnant, brush the Suspicious Sand in the side rooms of the pyramid shaft to find the Necklace of the desert, then right-click the Remnant with it. The Maledictus sits behind the Door of Seal, and you open it with a Strange Key dropped by the Aptrgangr.^[3]

The Leviathan needs an Abyssal Sacrifice. The pack changed this recipe, which has two versions. It uses an Athame from Deepling Warlocks and Priests, plus either Crystallized Coral or a Coral Chunk from Coral Golems and Coralssus. The Abyssal Sacrifice is also a task in the Chapter 3: The ATM Star quest line ("Abyssal Sacrifice" quest), so this boss also feeds into the pack's main progression.^[3][4][5]

Step 3: Boss materials and their gear

Ancient Metal is your first real material. It drops from almost everything in the Cursed Pyramid, and "Ancient Metal" quest points you to Bone Reptile Armor and the Ancient Spear. The armor gives very good stats for its low cost. The Spear hits harder than a Netherite Sword and throws Sandstorms.^[3]

Witherite comes from The Harbinger. It always drops 1 block, which crafts into 9 ingots. The quests use Witherite for three weapons: the Laser Gatling, the Meat Shredder and the Wither Assault Shoulder Weapon. It also makes the Mechanical Fusion Anvil, which you'll need for the top tier.^[3]

Ignitium is the reward from the Ignis, and the boss drops only 1, so spend it carefully. You can use it on Ignitium armor, which upgrades Netherite armor with an Ignitium upgrade template. It also makes the Bulwark of the Flame, The Incinerator and Blazing Grips.^[3][5]

The Netherite Monstrosity drops the Infernal Forge, a pickaxe that mines up to Netherite tier. That means it can mine Allthemodium Ore in this pack. Its Monstrous Horn goes into the Monstrous Helm. The Ender Guardian drops the Gauntlet of Guard, and the Ender Golem drops the Void Core.^[3][5]

Scylla's Essence of the Storm and Lacrima craft both Astrape and Ceraunus, in different shapes. The Maledictus unlocks a quest in "Cataclysm" for the Cursium Ingot. Cursium upgrades Netherite armor and goes into the Cursed Bow, Soul Render and The Annihilator.^[3][5]

Step 4: Fusion gear

The top tier is made in the Mechanical Fusion Anvil. Put one item in the left slot and the other in the middle slot, and the result appears in the right slot. The anvil has no durability. These fusion results combine gear from different bosses, so this is where your earlier drops pay off.^[3][5]

Unverified The visible quest data doesn't set a required order between the eight bosses, and it doesn't show where Black Steel Ingots come from. Check the quest book and JEI in-game for both. This site does hold All the Mods 10's own recipes, read from the pack itself: look the item up in the item browser.

L_Ender's Cataclysm is mostly about tough dungeons and bosses, but in All the Mods 10 the pack connects its loot to the endgame. The pack adds its own recipes that need Cataclysm boss gear, and the main questline asks you for a Cataclysm item on the way to the ATM Star.^[4][5]

Abyssal Sacrifice and the ATM Star

The Abyssal Sacrifice does more than one job. In the Cataclysm chapter, the "Abyssal Sacrifice" quest quest shows you how to get one, because you need it to wake up The Leviathan in the Sunken City.^[3]

The same item also appears in Chapter 3: The ATM Star. The "Abyssal Sacrifice" quest quest calls it the easiest item you'll need from Cataclysm for the ATM Star. If you're working toward the star, save an extra one instead of using every Sacrifice on Leviathan fights.^[4]

Dragon Soul

The pack adds a custom recipe for the Dragon Soul. It combines items from lots of different mods, and the Cataclysm part is the Abyssal Sacrifice. That means you need to be able to make Sacrifices before you can craft this.^[5]

Infernal Forge as a pickaxe

The Infernal Forge drops from the Netherite Monstrosity. It looks like a weapon, but it's actually a pickaxe that mines up to Netherite tier. That's enough to mine Allthemodium Ore, one of the pack's key ores.^[3]

Unverified The provided sources don't confirm whether the Dragon Soul or the Oblivion Shard is used in the ATM Star recipe itself. Check the Chapter 3 quests in game to see where they fit.

In All the Mods 10 8.1, L_Ender's Cataclysm has its own quest chapter called Cataclysm, and it also appears in Chapter 3: The ATM Star. The Cataclysm chapter follows a clear path. You find the eyes, summon and beat the bosses, collect their drops and materials, craft gear from them, and finally fuse items together into the strongest weapons.^[3][4]

Step 1: The boss eyes

After the "Eye see you!" quest, the chapter branches into one quest per eye. Each eye points you to a structure and the boss that lives there.^[3]

• "Eye of Mech" quest: Eye of Mech leads to the Ancient Factory and The Harbinger.^[3]
• "Eye of Flame" quest: Eye of Flame leads to the Burning Arena and the Ignis.^[3]
• "Eye of Void" quest: Eye of Void leads to the Ruined Citadel and the Ender Guardian.^[3]
• "Eye of Monstrous" quest: Eye of Monstrous leads to the Soul BlackSmith and the Netherite Monstrosity.^[3]
• "Eye of Abyss" quest: Eye of Abyss leads to the Sunken City and the Leviathan.^[3]
• "Eye of Desert" quest: Eye of Desert leads to the Cursed Pyramid and the Ancient Remnant.^[3]
• "Eye of Curse" quest: Eye of Curse leads to the Frosted Prison and the Maledictus.^[3]
• "Eye of Storm" quest: Eye of Storm leads to the Acropolis and Scylla.^[3]

Step 2: Waking up the bosses

Four bosses need an item before you can fight them, and each has its own quest.^[3]

• "Necklace of the desert" quest: Brush the Suspicious Sand in the side rooms of the Cursed Pyramid shaft to find the necklace. Then right-click the Ancient Remnant with it.^[3]
• "Burning Ashes" quest: Beat the Ignited Revenant for Burning Ashes, then use them on the Altar of Fire to summon the Ignis.^[3]
• "Abyssal Sacrifice" quest: Craft the Abyssal Sacrifice to fight the Leviathan. Deeplings, Coral Golems and Coralssus drop some of the parts.^[3]
• "Strange Key" quest: Take the Strange Key from the Aptrgangr to open the Door of Seal on the way to the Maledictus.^[3]

Step 3: Materials and drops

Beating the bosses unlocks the material quests. "Wither plus Netherite = ...?" quest asks for Witherite from The Harbinger. It always drops 1 block, which makes 9 ingots. "Ignitium" quest asks for Ignitium, and the Ignis drops only 1, so use it wisely. "Ancient Metal" quest covers Ancient Metal from the Cursed Pyramid, and a quest in "Cataclysm" asks for a Cursium Ingot after the Maledictus.^[3]

Other quests reward boss drops directly, including "Infernal Forge" quest, "Gauntlet of Guard" quest, "Void Core" quest, "Tidal Claws" quest and "Chitin Claw" quest. There are also pet quests: "Netherite Ministrosity" quest, "Abyssal Egg" quest and "What shall not be named for my crashing reasons" quest.^[3]

Step 4: Crafting gear

• Witherite: "Laser Gatling" quest, "Meat Shredder" quest, "W.A.S.W. (Wither Assault Shoulder Weapon)" quest and "Mechanical Fusion Anvil" quest.^[3]
• Ignitium: "Bulwark of the Flame" quest, "The Incinerator" quest, "Blazing Grips" quest and "Ignitium Armor" quest.^[3]
• Ancient Metal: "Ancient Spear" quest and "Bone Reptile Armor" quest.^[3]
• Cursium: "The Annihilator" quest, "Soul Render" quest, "Cursed Bow" quest and "Cursed Armor" quest.^[3]
• Scylla's loot: "Astrape" quest and "Ceraunus" quest.^[3]

Step 5: Fusion weapons

The final tier of quests needs the Mechanical Fusion Anvil to combine Cataclysm items. These quests are "Void Forge" quest, "V.A.S.W. (Void Assault Shoulder Weapon)" quest, "Gauntlet of Bulwark" quest, "Gauntlet of Maelstorm" quest, "The Immolator" quest, "Wrath of the Desert" quest, "Ignitium Elytra Chestplate" quest and "Brontes" quest.^[3]

Side quests: accessories

The smaller Cursed Pyramid and Frosted Prison structures have their own accessory quests. They start with "New Accessories" quest, which asks for the Belt of Beginner. The others are "Ring of Grudged" quest, "Berserker Soul Amulet" quest, "Sturdy Boots" quest, "Unbreakable Skull" quest, "Vitality Ankh" quest and "Khopesh" quest.^[3]

The ATM Star

In Chapter 3: The ATM Star, "Abyssal Sacrifice" quest asks for the Abyssal Sacrifice and comes after the Cataclysm quest. The chapter describes it as the easiest Cataclysm item you'll need for the ATM Star.^[4]

Unverified The ATM Star chapter may need other Cataclysm items as well, but the available quest data doesn't confirm which ones.

All the Mods 10 retunes Cataclysm a lot. Almost every boss hits harder and has more health than in the base mod. In exchange, the cooldowns on the boss gear you earn are much shorter. If you've fought these bosses in another pack, expect a very different fight here.^[7]

Each mob has a health multiplier and an attack multiplier, and both default to 1 in the mod. This pack raises them on every boss, so they're the biggest reason fights feel tougher.^[7]

• Scylla: mobs.scylla.combat_config.health_multiplier is 22.2 and mobs.scylla.combat_config.attack_multiplier is 18.^[7]
• Maledictus: health multiplier 20, attack multiplier 18.^[7]
• Ender Guardian: health multiplier 20, attack multiplier 8.^[7]
• Netherite Monstrosity: health multiplier 16, attack multiplier 12.^[7]
• The Leviathan: health multiplier 16, attack multiplier 10.^[7]
• Ignis: health multiplier 16, attack multiplier 8.^[7]
• The Harbinger: health multiplier 12, attack multiplier 8.^[7]
• Ancient Remnant: health and attack multipliers are both 6.^[7]

Damage caps

Bosses also have a damage cap and a DPS cap, and the pack raises both on most of them. Scylla goes from 21 to 210 on mobs.scylla.cap_config.damage_cap and from 13 to 130 on DPS. The Netherite Monstrosity goes to 180 and 144 (defaults 25 and 20), and Maledictus goes to 120 and 78 (defaults 20 and 13). The Leviathan is set to 80 and 60, the Ender Guardian to 70 and 41.4, the Harbinger to 50 and 45, and Ignis to 40 and 28. The Ancient Remnant keeps the mod defaults of 21 and 14.^[7]

Healing and special attacks

• mobs.harbinger.harbinger_life_steal is 45 instead of 5, and mobs.harbinger.harbinger_auto_heal is 8 instead of 2.^[7]
• Ignis's life steal multiplier, mobs.ignis.healing_multiplier, is 4 instead of 1.^[7]
• Nature Heal on the Netherite Monstrosity is 85 and on the Leviathan is 45, up from the default 25.^[7]
• The Netherite Monstrosity's mobs.netherite_monstrosity.lava_bomb_amount and mobs.netherite_monstrosity.lava_bomb_magazine are both 10 instead of 3.^[7]
• The Leviathan's mobs.leviathan.immune_out_of_water is set to true.^[7]

Faster boss gear

The good news is that your rewards got buffed too. Most weapon and ability cooldowns are cut to about a quarter of the mod default.^[7]

• tools_and_abilities.incinerator.incinerator_cooldown: 100 (default 400).^[7]
• tools_and_abilities.sandstorm.sandstorm_cooldown: 75 (default 300).^[7]
• tools_and_abilities.immolator.immolator_cooldown: 75 (default 250).^[7]
• tools_and_abilities.gauntlet_of_maelstrom.maelstrom_cooldown: 45 (default 180).^[7]
• tools_and_abilities.void_core.void_core_cooldown: 40 (default 160).^[7]
• tools_and_abilities.void_forge.void_forge_cooldown: 30 (default 100). tools_and_abilities.soul_render.soul_render_cooldown: 25 (default 100).^[7]
• Infernal Forge, Bulwark of the Flame and Gauntlet of Bulwark cooldowns: 20 each (default 80).^[7]
• Wither Assault Shoulder Weapon: missile cooldown 10 (default 40) and howitzer cooldown 25 (default 100). The Void Assault Shoulder Weapon howitzer is 30 (default 160).^[7]

Unverified The config file doesn't say which units the cooldown values use (ticks or seconds). It also doesn't explain exactly how the "HP damage" values (range 0 to 1) and the damage caps are applied in combat.

All the Mods 10 8.1 ships L_Ender's Cataclysm version 3.33, the 1.21.1 build of the mod. The mod has been part of the pack since at least All the Mods 10 2.25, so it has been around for most of the pack's life.^[2]

The pack team has kept Cataclysm updated through many releases, sometimes one version at a time and sometimes several at once. Here's how the mod's version moved across the pack updates, newest first.^{[8][9][10][11][12][13][14][15][16][17][18][19]}

Unverified The pack changelogs only record version numbers, and no mod changelogs for these builds were available. What each update actually changed (new bosses, items, balance tweaks or bug fixes) is unverified here, as is the mod's version history before the 3.04 to 3.07 update.
