This release bumps the minor version to reflect the change in splitting the build and host folders originally introduced by 3.1.4. That change has proven to be disruptive to many users, and we felt it necessary to bump a minor version to indicate that people should pay attention to this change. There's more info in our docs at https://conda.io/docs/user-guide/tasks/build-packages/define-metadata.html#host Enhancements: ------------- * Add log messages for each source of variants, so that you know where values are coming from #2597 Bug fixes: ---------- * remove unnecessary looped rm_rf when cleaning out prefixes between outputs #2587 * fix meta.yaml not found errors when trying to test packages built with --no-include-recipe #2590 * fix zipped key group with single entry causing a list to be passed later for single string values #2596 * fix incomplete change to splitting build and host envs #2595 * fix merging of top-level requirements and output reqs when output named same as top-level #2595 * fix handling of outputs with templates in their name (they were losing their requirements) #2595 * fix test file copying to avoid re-provisioning source during tests #2595 * tweak requirements regex to avoid misinterpreting python executable usage in test commands as usage of the python variant #2595
