January 2026 monthly summary across conda-forge/staged-recipes, conda/rattler, and conda-forge/conda-forge-pinning-feedstock. Delivered scalable variant configuration for rattler-build, improved build hygiene by pruning non-essential artifacts, and expanded packaging capabilities with wheel archives. Resolved a dependency warning for gtksourceview in the recipe, and extended macOS ARM64 platform coverage by adding gtksourceview to the supported libraries. These efforts reduce maintenance burden, improve artifact quality, broaden platform compatibility, and set foundations for easier adoption of new package formats across the ecosystem.
