+# 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).
+
+## [0.7.0] - 2024-06-01
+
+### Changed
+
+- [PR #13] Adds support for per-item file options by the `create_from_directory_with_options` method. This introduces a breaking change; instead of passing a `FileOptions` directly an `Fn` must be specified that is called for each file, and must return a `FileOptions` value.
+- Upgraded the zip dependency to version 0.6.6.
+
+
+## [0.6.2] - 2023-09-03
+
+### Changed
+
+- [PR #10] Upgraded the zip dependency to version 0.6.2
+
+
+## [0.6.1] - 2021-07-30
+
+### Fixed
+
+- [PR #6] Fixes formatting and linter warnings
+
+
+## [0.6.0] - 2020-11-30
+
+### Changed
+
+- [PR #4] Pass through Zip and IO errors (replaces all instances of `unwrap()`)
+- [PR #4] Adds tests; extends the `try_is_zip`  method so that it can detect different archive formats
+
+
+## [0.5.0] - 2020-07-24
+
+### Fixed
+
+- [PR #1] Fixes a bug in the `create_from_directory_with_options` method that could cause files not entirely written to disk; use `write_all` instead of `write`.
+
+
+## [0.4.0] - 2020-03-25
+
+### Added
+
+- New archive extraction traits `extract`, `extract_file`, and `extract_file_to_memory`
+- New entry query traits `entry_path` and `file_number`
+- New archive writer traits `create_from_directory` and  `create_from_directory_with_options`
+- Helper function that can perform all operations base on a given archive file path
