4.0.0

Breaking changes

• The !env tag has been removed, environment variables can now be loaded anywhere
• The cfg:// syntax has been replaced with !cfg path.to.value
• !cfg now redirects to a path in the current file (instead of the first loaded file)
  • Use !import to load a path in another file
• The ext://module.submodule.object syntax has been replaced with !ext module.submodule.object
• Replaced load_config_from_file with a configue.load function, which is now the main entrypoint of the library
  • use configue.load("/path/to/file.yml") to load a file
  • use configue.load("/path/to/file.yml", "path.to.section") to load only a section of a file
  • loading a path in a file recursively loads all children (replaced the lazy-loading with path loading),
    see README for more details
• Removed the load_config_from_dict function
• The !list tag has been removed, set your environment variable to [value_1, value_2] instead

Migration guide

• Remove all !list tags, and replace your environment variables from value1,value2 to [value1,value2]
• Replace ext://path.to.load with !ext path.to.load
• If you are using !import to import a file containing values with cfg://path.to.load, replace the cfg://... with
  !import:path/to/root/file.yml path.to.load
• Replace cfg://path.to.load with !cfg path.to.load
• Replace configue.load_config_from_file(...) with configue.load(...)
• Replace configue.load_config_from_file(...)["path"]["to"]["load"] with configue.load(..., "path.to.load")

Features
