This release makes YAML v3 and TOML v2 the default versions used for encoding.

You can switch back to the old versions by adding viper_yaml2 and viper_toml1 to the build tags.

Please note that YAML v2 and TOML v1 are considered deprecated from this release and may be removed in a future release.

Please provide feedback in discussions and report bugs on the issue tracker. Thanks!
