Minecraft 26.3 Snapshot 5: everything you need to know about the update

Mojang has released another snapshot, and this time it brings plenty of interesting changes. Minecraft 26.3 Snapshot 5 is focused on technical updates: from a new version structure to shader improvements and fixes for long-standing bugs. If you follow the game’s development or create your own data packs and shaders, this article will help you quickly understand what changed and how it may affect your game.

New version structure: Data Pack 112.0 and Resource Pack 92.0

The snapshot updates the pack versions: Data Pack has been raised to 112.0, while Resource Pack is now 92.0. These are not just numbers. A version change means older packs may need updates to work properly. If you use third-party data packs or resource packs, make sure their creators have already released compatible versions.

Data pack changes: mixing inline values and references

One of the key additions in this snapshot is the ability to mix inline values and references in lists inside data packs. Previously, developers had to choose one format for an entire list, which seriously limited flexibility. Now both approaches can be combined within a single file, making it much easier to build more complex mechanics and data structures.

World generation changes: minecraft:sculk_patch update

The snapshot also affects world generation. The updated minecraft:sculk_patch function changes how sculk spreads in deep biomes. This may affect existing worlds and seeds where sculk used to generate in a specific way. Map makers and server admins should check whether this could disrupt their projects.

Shader and rendering changes: ShaderC, #include, and explicit locations

For shader creators, this snapshot is genuinely good news. Mojang has switched to ShaderC for compiling OpenGL shaders, replaced the outdated #moj_import syntax with standard #include, and also added support for explicit locations. These changes bring Minecraft’s engine closer to modern graphics programming standards and should improve both compatibility and performance for shader packs.

Bug fixes: from chunks to the Ender Dragon

The snapshot also resolves a whole list of issues that have been bothering players for a long time:

• Chunks — loading issues were fixed that could cause blocks to «disappear» or render incorrectly.
• Ender Dragon — bugs related to its behavior during the final battle were fixed.
• Decorated Pots — a visual issue was fixed where pot patterns displayed incorrectly.
• Chat — problems with message display in multiplayer were fixed.
• Vulkan — crashes and rendering artifacts on devices using the Vulkan API were resolved.
• Commands — errors in how certain commands were processed were fixed, removing unpredictable behavior.

What will change for different types of players

The snapshot will affect different parts of the audience in different ways:

• Regular players will notice the improvements mainly through bug fixes — the world will feel more stable, and dragon fights will be more predictable.
• Data pack creators will gain more flexibility thanks to mixed list formats, opening up new possibilities for custom mechanics.
• Shader authors will need to update their project syntax: moving from #moj_import to #include will require small edits, but the result will be more compatible and reliable.
• Server administrators should check whether their installed data packs are compatible with the new version and update them if needed.

Snapshot 5 is an important step forward

Minecraft 26.3 Snapshot 5 is not a flashy content announcement, but it is an important technical milestone. The changes to shaders, data packs, and world generation show that Mojang is steadily working on the game’s stability and extensibility.
