 ## [Unreleased]
 
+## [0.23.0] - 2025-01-07
+### Fixed
+- Bearer tokens with nested JSON string are now properly handled. Thanks to [`Patrick Rodrigues`](https://github.com/pythrick).
+- Client credentials auth instances will now use credentials (client_id and client_secret) as well to distinguish tokens. This was an issue when the only parameters changing were the credentials.
+
+### Changed
+- Requires [`httpx`](https://www.python-httpx.org)==0.28.\*
+- Exceptions issued by `httpx_auth` are now inheriting from `httpx_auth.HttpxAuthException`, itself inheriting from `httpx.HTTPError`, instead of `Exception`.
+
+### Added
+- Explicit support for python `3.13`.

+#### Text-mode web browser
+
+This project uses [`webbrowser.open()`][4] to open a web browser to support authentication flows like OAuth's Authorization Code grant. When running graphically, `webbrowser.open()` does not block. But when run in text mode, `webbrowser.open()` blocks until the opened browser is closed, which leads to a deadlock when httpx-auth cannot serve the auth response pages to the webbrowser. To work around this, you can specify a `BROWSER` environment variable that contains a `%s` and ends with a `&`, and the `webbrowser` module will open the text-mode browser in a subprocess and allow httpx-auth to serve the auth response pages to the browser without deadlocking.
+
+```bash
+BROWSER="/usr/bin/links %s &"
+```
+
+For more information, please see the implementation of [`webbrowser.get()`][5].
