Originally announced during Minecraft Live September 2026, Minecraft 26.4 is on track to bring an abundance of winter features just in time for the holidays! Today, we'll explore the Minecraft 26.4 Winter Game Drop Update, its release date, and some of the most exciting new additions in its patch notes so far.

Minecraft 26.4 Release Date

The Minecraft 26.4 update does not yet have an official release date just yet. However, an estimate based on previous winter game drops suggests a release date around early December, as anything later could miss the holiday release window. As for 26.4 snapshots, six have been released so far, and you can play them all today! These include some exciting new additions for players to test, like Ice Caves, Frostbite Zombies, and Freezing Potions.

Minecraft 26.4 Update: New Content Highlights

Ice Caves

• Location: Overworld (Below Cold Biomes)

Located in the Overworld beneath cold biomes, ice caves feature a mixture of packed ice, calcite, and snow alongside stone. Throughout the cave, large icicles hang from the ceiling and fall at the touch of light, gently glowing ice crystals cover the ground, and crevasses lie beneath patches of brittle ice that break if weight is applied. Just be wary of the frostbite zombies that can also be found lurking inside!

New Snow & Ice Blocks

• Requires: Snow Blocks & Packed Ice Blocks

With this winter expansion, both snow and packed ice are receiving full block sets! Packed ice can be crafted into packed ice bricks, stairs, slabs, and walls both on a crafting table and with a stonecutter. Snow blocks are similarly able to be crafted into snow bricks, stairs, and slabs, but they must be crafted on a crafting table and are broken most easily with a shovel.

Frostbite Zombie

• Location: Snowy Biomes

Spawning in snowy biomes across the Overworld, the frostbite zombie is a dangerous zombie variant capable of devastating melee attacks that apply the freezing status effect, which both slows and causes damage over time. Further yet, if the frostbite zombie happens to spawn with an ice ball in hand, it can attack at range as well. One can only hope that they do not encounter a frostbite jockey!

Ice Balls & Freezing Potions

• Brewing Recipe: Awkward Potion, Ice Balls, & Gunpowder

Dropped by frostbite zombies, ice balls are a variant of snowballs that deal damage and knock back entities. Additionally, ice balls can be used to brew the new freezing potion, which applies the freezing effect, both slowing enemies and damaging them over time.

How to Install Minecraft 26.4 Snapshots

As of October 27, 2026, snapshot 6 is the latest available for Minecraft 26.4. Those looking to test its features can do so from right inside the Minecraft client. The necessary steps can each be found below:

1. Open the Minecraft Launcher and select Java Edition.
2. Enable snapshots under the ‘Installations’ tab.
3. If a new installation called “Latest Snapshot,” represented by a dirt block, is now present, that can be used immediately to start playing. Otherwise, proceed with step four.
4. Click ‘New Installation’
5. Select ‘Latest Snapshot’ in the drop-down menu.
6. Click ‘Install.’

With these steps complete, the new snapshot installation becomes a selectable option before clicking play, and updates automatically when a new snapshot releases. New releases can corrupt old worlds! Ensure backups have been taken.

Minecraft 26.4 Snapshot 1

Changes World Generation

• Upgrading worlds from before Caves and Cliffs will now also generate sulfur caves below old chunks

Minor Tweaks to Blocks, Items and Entities

• Red and Brown Mushrooms can now be placed on any block with a solid top face regardless of lighting conditions
  • They can still not spread unless the brightness is less than 13, or their support block overrides light requirements

"Graphics API" Video Setting

• "Default" now behaves the same as "Prefer Vulkan"
• The game will no longer change the graphics API setting automatically if a startup crash is detected.

Technical Changes

• The Data Pack version is now 122.0
• The Resource Pack version is now 98.0

Network Protocol Added minecraft:mod_list Custom Packet Payload

• This packet is intended to inform servers about client mods to simplify debugging
• Vanilla client sends an empty packet at the start of configuration phase, as it does not know about any mods - that is still a responsibility of 3rd-party modding platforms

Modified minecraft:intention Packet

• The host field in the serverbound intention packet can now hold additional parameters (previously it stored only the domain name used for connecting to a server)
  • The new format is similar to URI query strings - the domain can now optionally be followed by a ? character and then followed by key=value pairs separated by a & character
  • Empty values can be omitted (including = sign)
  • Keys and values are escaped according to the standard URI rules ("percent-encoded component")
  • Keys starting with _ are reserved for vanilla use
  • Example: example.com?key1=value2&key2
  • Users can now input properties in any "Server Address" field in the server list
    • Additionally, any address in form of <id>@<host> will be parsed as <host>?_id=<id>
  • If a server uses SRV DNS records, the host field will contain both original and resolved domains
    • If the resolved domain is different from the original domain, the resolved one will be used as the "primary" one, while the original one will be added as _o ("origin") property
    • Example host string: <redirected domain>?_o=<original domain>:<original port>, while the port field in the intention packet will be set to the resolved port value
  • The field size has been extended to 1024 characters
  • Note: since the minecraft:intent packet is unencrypted, properties should not be used for any security-sensitive purpose

Modified minecraft:transfer Packet

• Added properties field - a string to string map of properties that will be added to the host field in the minecraft:intent packet sent to the target server

Dedicated Server Properties

• Added allowed-connection-ids
  • A list of comma-separted ids
  • If non-empty, the server will match the values against _id property in minecraft:intent packet
    • If there is no match, the server will reject the connection
  • This works both for both status and login connections, so any user connecting without the correct _id in the server address will not see the status and will not be able to join the server
• Added status-contact-details field
  • If non-empty, the value of this field will be sent in the minecraft:status_response packet JSON payload under the contact property
  • This value is meant to be used to signal a way to contact the server owners about the server, even if there is no website or other information about it
  • This field is meant to be human-readable, but there are no other restrictions on field format
• Added enable-legacy-status field
  • This option allows disabling existing legacy (pre-1.7) server status and ping protocol handling
  • To preserve existing functionality, value defaults to true
  • Note: enable-status needs to be set for any status information (modern or legacy) to be set

Data Pack Version 122.0

• Entries for different biomes in multi-noise biome sources can no longer overlap across all noise parameters with the same offset

Commands

• The fillbiome command will now fill biomes with block accuracy
• NBT conversion from floating point types to integer types now always converts to the closest possible valid number after rounding down

World Generation Features Changed straight_trunk_placer

• Added trunk_width field
  • optional int provider, the width of the trunk centered around the origin
  • defaults to 1.0

Placed Features

• The possible domain in the XZ plane of Placed Features included in biomes is now validated
  • Feature placement can only occur within a 3x3 chunk region: as such, it is not valid for a Placed Feature to select a position outside of that range
  • Note: the size of the feature itself is not currently taken into consideration, which may still overflow the chunk

Placement Modifiers Changed cuboid

• xz_size and y_size have been adjusted to represent the actual size of the cuboid, instead of implicitly being 1 block larger
  • As such, an xz_size of 2 will actually produce a 2x2 cuboid instead of 3x3

Changed fixed_placement

• positions now requires at least one element

Noise Settings

• The default_block field has been removed
  • This is now always air - any other block should be defined by the Material Rule

Material Conditions Updated minecraft:steep

• No longer considers height modifications from Eroded Badlands "surface extensions" in an order-dependent way

Tags Biome Tags

• Added #generated_in_below_zero_retrogen - biomes to generate below worlds that predate Caves and Cliffs
• Added #is_cave collection tag

Resource Pack Version 98.0 Shaders & Post-process Effects Order-Independent Transparency shaders

• The OIT algorithm was simplified by replacing the wavelet-based mathematics with depth bin-based accumulation
  • Slightly improved performance at least on some devices
  • Reduced floating point precision issues on average
  • OIT_WAVELET_RANK shader define was removed
  • OIT_COEFF_COUNT shader define was replaced by OIT_NUMBER_OF_DEPTH_BINS
  • OIT_COEFF_ATTACHMENT_COUNT shader define was renamed to OIT_TRANSMITTANCE_TARGET_COUNT

• MC-299060 - Setting item frames' direction with commands can cause desyncs
• MC-303702 - Small gaps still appear in item models
• MC-307065 - Missing optimization for the side faces of the builtin/generated item model
• MC-310051 - Floating point cancellation artifacts from bits.fsh
