-# Update Log
-
-**This document details any major updates required to use new features or improvements in Viper.**
-
-## v1.20.x
-
-### New file searching API
-
-Viper now includes a new file searching API that allows users to customize how Viper looks for config files.
-
-Viper accepts a custom [`Finder`](https://pkg.go.dev/github.com/spf13/viper#Finder) interface implementation:
-
-```go
-// Finder looks for files and directories in an [afero.Fs] filesystem.
-type Finder interface {
-	Find(fsys afero.Fs) ([]string, error)
-}
-```
-
-It is supposed to return a list of paths to config files.
-
-The default implementation uses [github.com/sagikazarmark/locafero](https://github.com/sagikazarmark/locafero) under the hood.
-
-You can supply your own implementation using `WithFinder`:
-
-```go
-v := viper.NewWithOptions(
-    viper.WithFinder(&MyFinder{}),
-)
-```
-
-For more information, check out the [Finder examples](https://pkg.go.dev/github.com/spf13/viper#Finder)
-and the [documentation](https://pkg.go.dev/github.com/sagikazarmark/locafero) for the locafero package.
-
-### New encoding API
-
-Viper now allows customizing the encoding layer by providing an API for encoding and decoding configuration data:
-
-```go
-// Encoder encodes Viper's internal data structures into a byte representation.
-// It's primarily used for encoding a map[string]any into a file format.
-type Encoder interface {
-	Encode(v map[string]any) ([]byte, error)
-}
-
-// Decoder decodes the contents of a byte slice into Viper's internal data structures.
-// It's primarily used for decoding contents of a file into a map[string]any.
-type Decoder interface {
-	Decode(b []byte, v map[string]any) error
-}
-
-// Codec combines [Encoder] and [Decoder] interfaces.
-type Codec interface {
-	Encoder
-	Decoder
-}
-```
-
-By default, Viper includes the following codecs:
-
-- JSON
-- TOML
-- YAML
-- Dotenv
-
-The rest of the codecs are moved to [github.com/go-viper/encoding](https://github.com/go-viper/encoding)
-
-Customizing the encoding layer is possible by providing a custom registry of codecs:
-
-- [Encoder](https://pkg.go.dev/github.com/spf13/viper#Encoder) -> [EncoderRegistry](https://pkg.go.dev/github.com/spf13/viper#EncoderRegistry)
-- [Decoder](https://pkg.go.dev/github.com/spf13/viper#Decoder) -> [DecoderRegistry](https://pkg.go.dev/github.com/spf13/viper#DecoderRegistry)
-- [Codec](https://pkg.go.dev/github.com/spf13/viper#Codec) -> [CodecRegistry](https://pkg.go.dev/github.com/spf13/viper#CodecRegistry)
-
-You can supply the registry of codecs to Viper using the appropriate `With*Registry` function:
-
-```go
-codecRegistry := viper.NewCodecRegistry()
-
-codecRegistry.RegisterCodec("myformat", &MyCodec{})
-
-v := viper.NewWithOptions(
-    viper.WithCodecRegistry(codecRegistry),
-)
-```
-
-### BREAKING: "github.com/mitchellh/mapstructure" depedency replaced
-
-The original [mapstructure](https://github.com/mitchellh/mapstructure) has been [archived](https://github.com/mitchellh/mapstructure/issues/349) and was replaced with a [fork](https://github.com/go-viper/mapstructure) maintained by Viper ([#1723](https://github.com/spf13/viper/pull/1723)).
-
-As a result, the package import path needs to be changed in cases where `mapstructure` is directly referenced in your code.
-
-For example, when providing a custom decoder config:
-
-```go
-err := viper.Unmarshal(&appConfig, func(config *mapstructure.DecoderConfig) {
-	config.TagName = "yaml"
-})
-```
-
-The change is fairly straightforward, just replace all occurrences of the import path `github.com/mitchellh/mapstructure` with `github.com/go-viper/mapstructure/v2`:
-
-```diff
-- import "github.com/mitchellh/mapstructure"
-+ import "github.com/go-viper/mapstructure/v2"
-```
-
-### BREAKING: HCL, Java properties, INI removed from core
-
-In order to reduce third-party dependencies, Viper dropped support for the following formats from the core:
-
-- HCL
-- Java properties
-- INI
-
-You can still use these formats though by importing them from [github.com/go-viper/encoding](https://github.com/go-viper/encoding):
-
-```go
-import (
-    "github.com/go-viper/encoding/hcl"
-    "github.com/go-viper/encoding/javaproperties"
-    "github.com/go-viper/encoding/ini"
-)
-
-codecRegistry := viper.NewCodecRegistry()
-
-{
-    codec := hcl.Codec{}
-
-    codecRegistry.RegisterCodec("hcl", codec)
-    codecRegistry.RegisterCodec("tfvars", codec)
-
-}
-
-{
-    codec := &javaproperties.Codec{}
-
-    codecRegistry.RegisterCodec("properties", codec)
-    codecRegistry.RegisterCodec("props", codec)
-    codecRegistry.RegisterCodec("prop", codec)
-}
-
-codecRegistry.RegisterCodec("ini", ini.Codec{})
-
-v := viper.NewWithOptions(
-    viper.WithCodecRegistry(codecRegistry),
-)
-```
