Devlog: Cobble v0.6.1
Cobble v0.6.1 is focused on making Minecraft data pack development more reliable, more current, and easier to validate.
This release targets Minecraft Java Edition 26.1.2 and pack format 101.1, giving the compiler a clear modern baseline instead of trying to support older command formats.
The biggest improvement is validation. Cobble can now automatically generate the default data/commands.json by downloading the Minecraft server through Mojang’s version manifest and running the server reports generator. It also supports fallback URLs, custom server jars, and SHA1 checks for more controlled environments. This makes command validation much easier to run consistently.
We also improved diagnostics, source-map validation, and generated pack cleanup, especially around safer resource paths and stale generated functions. Standard library helpers were expanded, namespaced data pack resources are better supported, and the example projects now cover more real features.
Finally, v0.6.1 adds a repeatable Purpur server QA workflow, so generated packs can be tested beyond static validation. Overall, this release is about confidence: clearer errors, stronger checks, and a better foundation for future Cobble releases.
