NetSchematics 0.1.3 — Fabric compatibility update

Changes

• Expanded the tested Fabric builds to Minecraft 1.20, 1.20.1, 1.21, 1.21.1, 26.1, 26.1.1, 26.1.2, 26.2, and 26.3. Each download supports only the Minecraft versions listed on that file.
• Added a dedicated Minecraft 26.1 platform adapter and verified the same build on 26.1.1 and 26.1.2.
• Broadened Fabric Loader compatibility: 0.15.11 or newer for the 1.20/1.20.1 and 1.21/1.21.1 builds, 0.18.4 or newer for 26.1.x and 26.2, and 0.19.3 or newer for 26.3.
• Improved API-key input, saving, validation feedback, and the optional Mod Menu settings entry. Public browsing and public schematic downloads do not require an API key.
• Preserved schematic browsing, searching, filtering, previews, details, and download history across the supported builds.
• Included the Minecraft 26.3 input and rendering adapter, including SDL keyboard and text-input handling.

Validation

The release passed 594 automated tests, 20 real-client core-function combinations, and two expected dependency-rejection checks. Fabulously Optimized 26.3, Fabulously Optimized 1.21.1, and Simply Optimized 1.21.1 passed isolated startup and browser-interface smoke checks. These checks do not certify every gameplay feature or shader combination in those packs.

Installation

Install one NetSchematics JAR matching your Minecraft version, together with a matching Fabric API. Fabric API and other installed mods may require a newer Fabric Loader than the minimum listed above.

Litematica and Mod Menu remain optional integrations. Downloaded .litematic files are saved to the schematics directory. Choose the correct file for your Minecraft version; this release does not add support for Minecraft 1.21.2–1.21.11.
