v0.1.7: Fabric Server Support and Better Repeat Visuals

Axion v0.1.7 is a small update focused on two practical things:

• first real Fabric dedicated server support for Minecraft 1.21.11
• better move / stack / smear preview behavior, especially on larger edits

This patch is mainly about making the current editing flow feel safer and more readable without turning it into a major feature release.

If you are new to Axion:

• Fabric mod setup and usage: MOD-README
• Paper plugin setup and server notes: PLUGIN-README
• Documentation and wiki: Wiki

Highlights

• added supported Fabric dedicated server backing for Minecraft 1.21.11
• the 1.21.11 Axion Fabric jar is now dual-use for both client and Fabric server
• Fabric server now supports authoritative Erase, Clone, Move, Stack, Smear, Extrude, symmetry-backed placement, and undo/redo
• improved move preview behavior after the regression in the last update
• improved stack and smear preview readability, especially when changing directions
• large repeat previews now fall back more cleanly instead of showing confusing partial ghost blocks

Better Visualization

v0.1.7 includes another pass on the preview system, with the goal of making large edits clearer while also reducing wasted preview work.

The main practical improvements are:

• move previews are more reliable again after the broken behavior in the last release
• stack and smear previews are easier to read and less likely to flood the screen with misleading partial geometry
• large repeat previews now degrade more cleanly toward outline behavior instead of rendering scattered remainder blocks
• smear now follows the same improved repeat-preview flow as stack more closely when switching directions

This is also part of the longer-term preview renderer cleanup. The current direction is to move Axion toward a better shared visualization system that can handle large edits more efficiently and reduce CPU cost compared with the older preview path.

Fabric Server Support

The biggest platform change in v0.1.7 is the first supported Fabric dedicated server path for Minecraft 1.21.11.

For 1.21.11, the main Axion Fabric jar is now dual-use:

• install it in the client mods folder for the Fabric client
• install the same jar in the server mods folder for a Fabric dedicated server

Current Fabric server support includes:

• handshake / capability negotiation
• no-clip state sync
• authoritative Erase
• authoritative Clone
• authoritative Move
• authoritative Stack
• authoritative Smear
• authoritative Extrude
• symmetry-aware placement / replace-mode placement
• server-backed Undo / Redo

Server requirements:

• fabric-api
• fabric-language-kotlin

Paper remains the more mature backend for protection/policy integrations, but Fabric server support is now usable for real 1.21.11 testing and release.

Notes

For 1.21.11:

• the same Axion jar can now be used on both Fabric client and Fabric dedicated server
• update both sides together for the best result
• Paper plugin users should still update the plugin and client together as usual
