v0.17.2

• Fix dump functions failing to write nested Configuration instances in TOML format.

v0.17.1

• Avoid crashing on template loaders containing {extension}, issue a deprecation warning when this is used.

v0.17

• Drop support for Python 3.9.
• Introduce confidence.Format with three concrete implementations: confidence.JSON, confidence.TOML and confidence.YAML, which can be customized before use (e.g. format = YAML(suffix='.yml')).
• Deprecate the use of extension argument to loading functions and encoding argument to dumping functions, both can be controlled with a confidence.Format.

v0.16.1

• Let Configuration.get() mimic the behaviour of dict.get(), returning None by default for missing keys.

v0.16

• Drop support for Python 3.8.
• Add merge function to combine multiple mappings into a single Configuration.
• Enable the use of the binary or / union operator on Configuration instances, analogous to a builtin dict (e.g. config = defaults | overrides).

0.12

• Use named loggers, default confidence.* library loggers to silence as described in the docs.
• Resolve references in sequences.

0.11

• Parse values of environment variables as YAML values (e.g. NAME_KEY=yes will result in key being True)
• Add INFO-level logging of files and environment variables being used to load configuration

0.10

• Remove configurable key separator, hardcode the default.
• Rename enumeration values (like Locality.USER) to be upper case.
• Add dump, dumpf and dumps functions to dump Configuration instances to YAML format.

0.9

• Add type hints to confidence

0.8

• Add human-readable reprs to Configuration and ConfigurationSequence
• Make ConfigurationSequence more list-like by enabling addition operator (configured_sequence + [1, 2, 3] or (1, 2, 3) + configured_sequence)
