+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+<!--
+# Guiding Principles
+
+* Changelogs are for _humans_, not machines.
+* There should be an entry for every single version.
+* The same types of changes should be grouped.
+* Versions and sections should be linkable.
+* The latest version comes first.
+* The release date of each version is displayed.
+* Mention whether you follow Semantic Versioning.
+
+# Types of changes
+
+* `Added` for new features.
+* `Changed` for changes in existing functionality.
+* `Deprecated` for soon-to-be removed features.
+* `Removed` for now removed features.
+* `Fixed` for any bug fixes.
+* `Security` in case of vulnerabilities.

+## [Unreleased] - ReleaseDate
+
+## [2.0.0] - 2020-10-22
+### Breaking changed
+* Behavior of `config_dir` on macOS is changed.
+  According to [Apple guideline][appple-configdir], configuration files should be placed
+  in subdirectory of `Library/Application Support`. The old behavior of `config_dir`
+  returns `Library/Preferences`, which is incorrect. As users should use `CFPreferences`
+  API to get and set preference values for their app instead.
+
+[appple-configdir]: https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html#//apple_ref/doc/uid/TP40010672-CH2-SW1
+
+## [1.0.2] - 2020-10-13
+### Changed
+* Bump cfg-if version to v1
+
+## [1.0.1]
+### Fixed
+* Relax pinning `cfg-if` at `0.1.9`. Previously we inherited that from upstream repository when forking.
+  The original author wanted to keep minimum Rust version at 1.13 which we don't anymore.
+
+## [1.0.0] - 2020-05-17
+
+This is the re-publish of `dirs` crate as is.

+
+# `dirs-next`
+
+**Note**: This is a fork of once-abandoned `dirs` crate.
+
+There is a mid-level sister library, [directories-next].
+
+## Introduction
+
+- a tiny low-level library with a minimal API
+- that provides the platform-specific, user-accessible locations
+- for retrieving and storing configuration, cache and other data
+- on Linux, Redox, Windows (≥ Vista), macOS and other platforms.
+
+The library provides the location of these directories by leveraging the mechanisms defined by
+- the [XDG base directory](https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) and
+  the [XDG user directory](https://www.freedesktop.org/wiki/Software/xdg-user-dirs/) specifications on Linux and Redox
+- the [Known Folder](https://msdn.microsoft.com/en-us/library/windows/desktop/dd378457.aspx) API on Windows
+- the [Standard Directories](https://developer.apple.com/library/content/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html#//apple_ref/doc/uid/TP40010672-CH2-SW6)
+  guidelines on macOS
+
+## Platforms
+
+This library is written in Rust, and supports Linux, Redox, macOS and Windows.
+Other platforms are also supported; they use the Linux conventions.
+
+## Minimum Rust version policy
+
+The minimal required version of Rust is `1.34.0`.
+
+We may bump the Rust version in major and minor releases (`x`/`y` in `x.y.z`).
+Changing the Rust version will be written in the CHANGELOG.
+
+## Example
+
+Library run by user Alice:
+
+```rust
+dirs_next::home_dir();
+// Lin: Some(/home/alice)
+// Win: Some(C:\Users\Alice)
+// Mac: Some(/Users/Alice)
+
+dirs_next::audio_dir();
+// Lin: Some(/home/alice/Music)
+// Win: Some(C:\Users\Alice\Music)
+// Mac: Some(/Users/Alice/Music)
+
+dirs_next::config_dir();
+// Lin: Some(/home/alice/.config)
+// Win: Some(C:\Users\Alice\AppData\Roaming)
+// Mac: Some(/Users/Alice/Library/Application Support)
+
+dirs_next::executable_dir();
+// Lin: Some(/home/alice/.local/bin)
+// Win: None
+// Mac: None
+```
+
+## Design Goals
+
+- The _dirs-next_ library is a low-level crate designed to provide the paths to standard directories
+  as defined by operating systems rules or conventions. If your requirements are more complex,
+  e. g. computing cache, config, etc. paths for specific applications or projects, consider using
+  [directories-next] instead.
+- This library does not create directories or check for their existence. The library only provides
+  information on what the path to a certain directory _should_ be. How this information is used is
+  a decision that developers need to make based on the requirements of each individual application.
+- This library is intentionally focused on providing information on user-writable directories only.
+  There is no discernible benefit in returning a path that points to a user-level, writable
+  directory on one operating system, but a system-level, read-only directory on another, that would
+  outweigh the confusion and unexpected failures such an approach would cause.
+  - `executable_dir` is specified to provide the path to a user-writable directory for binaries.<br/>
+    As such a directory only commonly exists on Linux, it returns `None` on macOS and Windows.
+  - `font_dir` is specified to provide the path to a user-writable directory for fonts.<br/>
+    As such a directory only exists on Linux and macOS, it returns `None` on Windows.
+  - `runtime_dir` is specified to provide the path to a directory for non-essential runtime data.
+    It is required that this directory is created when the user logs in, is only accessible by the
+    user itself, is deleted when the user logs out, and supports all filesystem features of the
+    operating system.<br/>
+    As such a directory only commonly exists on Linux, it returns `None` on macOS and Windows.
+
+## Features
+
+**If you want to compute the location of cache, config or data directories for your own application or project,
+use `ProjectDirs` of the [directories-next] project instead.**

+//! The _dirs-next_ crate is
+//!
+//! - a tiny library with a minimal API (16 functions)
+//! - that provides the platform-specific, user-accessible locations
+//! - for finding and storing configuration, cache and other data
+//! - on Linux, Redox, Windows (≥ Vista) and macOS.
+//!
+//! The library provides the location of these directories by leveraging the mechanisms defined by
+//!
+//! - the [XDG base directory](https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) and the [XDG user directory](https://www.freedesktop.org/wiki/Software/xdg-user-dirs/) specifications on Linux,
+//! - the [Known Folder](https://msdn.microsoft.com/en-us/library/windows/desktop/bb776911(v=vs.85).aspx) system on Windows, and
+//! - the [Standard Directories](https://developer.apple.com/library/content/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html#//apple_ref/doc/uid/TP40010672-CH2-SW6) on macOS.
