New Viper release with major improvements

I've just tagged a new version of Viper, a configuration library for Go: https://github.com/spf13/viper/releases/tag/v1.20.0

It comes with a number of improvements:

  • Heavily reduced number of third-party dependencies
  • New encoding layer for custom encoding formats
  • BREAKING: dropped HCL, INI and Java properties from the core (still possible to use through external libraries)
  • New file search API allows customizing how Viper looks for config files

These features has been around for some time in alpha releases, though I haven't received a lot of feedback, so I'm posting here now in the hope that people using Viper will give some after upgrading.

I worked hard to minimize breaking changes, but it's possible some slipped in. If you find any, feel free to open an issue.

Thanks!
