v1.18.2

Compare Source

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.

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.

Minimum Go version: 1.19

Viper now requires Go 1.19

This change ensures we can stay up to date with modern practices and dependencies.

log/slog support [BREAKING]

Viper v1.11.0 added an experimental Logger interface to allow custom implementations (besides jwalterweatherman).

In addition, it also exposed an experimental WithLogger function allowing to set a custom logger.

This release deprecates that interface in favor of log/slog released in Go 1.21.

[!WARNING]
WithLogger accepts an *slog.Logger from now on.

To preserve backwards compatibility with older Go versions, prior to Go 1.21 Viper accepts a *golang.org/x/exp/slog.Logger.

The experimental flag is removed.

New finder implementation [BREAKING]

As of this release, Viper uses a new library to look for files, called locafero.

The new library is better covered by tests and has been built from scratch as a general purpose file finder library.

The implementation is experimental and is hidden behind a finder build tag.

[!WARNING]
The io/fs based implementation (that used to be hidden behind a finder build tag) has been removed.
