• Previously, zio-config mistakenly treated comma-separated values as lists because it used the ConfigProvider.Flat.util.parsePrimitive method internally. This is now fixed, and now we no longer need to use seqDelim to indicate that values should be treated as lists. For example, a list value is always within [] for HOCON/JSON.
• This fix resolves potential issues like the one described in #1085.
• XML support has been moved to the experimental stage until it can handle all complex types.
