     * v5:
         - Minimum `mujoco` version is now 2.3.3.
         - Added support for fully custom/third party `mujoco` models using the `xml_file` argument (previously only a few changes could be made to the existing models).
+        - Added `default_camera_config` argument, a dictionary for setting the `mj_camera` properties, mainly useful for custom environments.
         - Added `env.observation_structure`, a dictionary for specifying the observation space compose (e.g. `qpos`, `qvel`), useful for building tooling and wrappers for the MuJoCo environments.
         - Added `frame_skip` argument, used to configure the `dt` (duration of `step()`), default varies by environment check environment documentation pages.
         - Fixed bug: `healthy_reward` was given on every step (even if the Pendulum is unhealthy), now it is only given if the Pendulum is healthy (not terminated) (related [Github issue](https://github.com/Farama-Foundation/Gymnasium/issues/500)).
