Full Changelog: v1.18.1...v1.19.0

v1.18.2

tl;dr Skip 1.18.0 and 1.18.1 and upgrade to this version instead.

This release fixes a regression that appears in rare circumstances when using Unmarshal or UnmarshalExact to decode values onto pointers with multiple indirection (eg. pointer to a pointer, etc). The change was introduced in 1.18.0 as a means to resolve a long-standing bug when decoding environment variables to structs.

The feature is now disabled by default and can be enabled using the viper_bind_struct build tag. It's also considered experimental at this point, so breaking changes may be introduced in the future.

Highlighting some of the changes for better visibility.

Please share your feedback in the Discussion forum. Thanks! ❤️

AutomaticEnv works with Unmarshal

Previously, environment variables that weren't bound manually or had no defaults could not be mapped by Unmarshal. (The problem is explained in details in this issue: #761)

#1429 introduced a solution that solves that issue.
