Added

• Allow BindEnv to register multiple environment variables
• Support for accessing slices
• Experimental WASM support: Viper compiles on WASM
• INI load options

Changed

• Ensure BindPFlag detects a nil flag parameter

Fixed

• Merging a key into a nil target
• Panics during saving INI files

Security

• Updated etcd to 3.5 which should make a lot of false positive vulnerability reports disappear
