### Bug Fixes

## [Unreleased] - ReleaseDate

## [5.0.4] - 2023-06-08

### Changed

- The `FileSystemMapping` now contains an `original_path` field, allowing
  consumers to mount individual directories from a volume, rather than being
  forced to mount the entire volume
  ([#127](https://github.com/wasmerio/pirita/pull/127))

## [5.0.3] - 2023-06-06

### Added

- Added a `FileSystemMappings` package annotation for declaring how volumes
  should be mapped when instantiating a package
  ([#119](https://github.com/wasmerio/pirita/pull/119))
- Added getter methods for well-known package and command annotations
  ([#119](https://github.com/wasmerio/pirita/pull/119))

### Changed

- Abstracted the logic for `webc::compat::SharedBytes` out into its own crate
  ([#114](https://github.com/wasmerio/pirita/pull/114))

## [5.0.2] - 2023-05-28

### Fixed

- Fixed a bug where the compatibility layer would panic when reading a
  zero-length atom from a v1 WEBC file
  ([#117](https://github.com/wasmerio/pirita/pull/117))

## [5.0.1] - 2023-05-27

### Fixed

- For v2 WEBC files, the compatibility layer was returning the wrong names from
  `Container::volume_names()`
  ([#115](https://github.com/wasmerio/pirita/pull/115))
