3.1.0

Enhancements:

• Speed up package inspection by optimizing package file lookup #2535

• Simplify hashing scheme. A hash will be added if all of these are true for any dependency:

  • package is an explicit dependency in build, host, or run deps
  • package has a matching entry in conda_build_config.yaml which is a pin to a specific version, not a lower bound
  • that package is not ignored by ignore_version

  OR

  • package uses {{ compiler() }} jinja2 function

  All other packages will no longer have hashes. The takeaway message is that
  hashes will appear when binary compatibility matters, but not when it doesn't. #2537

Bug fixes:

• Allow packages to store files in info folder #2538
• Fix source_files not working correctly when using test files in packages #2539
