Breaking Changes

• All keys in sources are loaded as little camel case by default, e.g., tcpPort and tcp_port in the source are treated as the same key. You can use config.disable(Feature.LOAD_KEYS_AS_LITTLE_CAMEL_CASE) to disable this change.

Deprecated

• fromXXX APIs on providers are removed use the new shorter APIs instead. E.g., you can use file instead of fromFile.
