+## [1.0.3] - 2022-01-31
+
+### Changes
+
+- When a user provides an incorrect value for an option, an `ArgumentParser`-based program now includes the valid values when possible.
+
+    ```
+    $ example --format png
+    Error: The value 'png' is invalid for '--format <format>'.
+    Please provide one of 'text', 'json' or 'csv'.
+    ```
+
+### Fixes
+
+- Resolves an issue with `zsh` custom completions for command names that include a dash.
+- Improves the generated completions scripts for `fish`.
+- Resolves issues that prevented building `ArgumentParser` for WebAssembly using SwiftWasm toolchains.
+- Improved window size handling on Windows.
+- Fixed a crash when using `--experimental-dump-help` with commands that provide non-parsed values.
+- Fixes an issue where subcommands that declare array arguments with the `.unconditionalRemaining` parsing strategy unexpectedly miss arguments, extending the change in [#333] to subcommands. ([#397])
+- Corrects the order of an `@Option` initializer's parameters, deprecating the old version. ([#391])
+- Expanded and corrected documentation.
