 ### ✨ Features
 - Add support for BSD and other non-Linux Unix-like FOSS desktop systems. All systems running a supported Desktop Environment (currently: KDE, Gnome + other freedesktop compliant DEs) should be supported. ([#379](https://github.com/fohrloop/wakepy/pull/379), [#385](https://github.com/fohrloop/wakepy/pull/385))
+- Add support for PyPy ([#393](https://github.com/fohrloop/wakepy/pull/393) and [#396](https://github.com/fohrloop/wakepy/pull/396))
 - When running on an *unknown* platform, do not fail any Methods in the platform check phase anymore, but try to use each Method. This means for example that any system running GNOME that is not Linux (or BSD) could still use wakepy with the [org.gnome.SessionManager](https://wakepy.readthedocs.io/stable/methods-reference.html#org-gnome-sessionmanager) ([#379](https://github.com/fohrloop/wakepy/pull/379))
 - 🚨 CLI arguments: Change `-k, --keep-running` to be `-r, --keep-running` and `-p, --presentation` to be `-p, --keep-presenting`; Be more consistent with the naming of the [Modes](#wakepy-modes). The old alternatives are deprecated and will be removed in a future release. ([#356](https://github.com/fohrloop/wakepy/pull/356))
 - 🚨 Renamed [`PlatformName`](https://wakepy.readthedocs.io/v0.9.0.post1/api-reference.html#wakepy.core.constants.PlatformName) to [`PlatformType`](https://wakepy.readthedocs.io/v0.10.0/api-reference.html#wakepy.core.constants.PlatformType) and added new types: `ANY`, which means "any platform", `BSD`, meaning "any BSD system" in the future, but currently just FreeBSD / GhostBSD, and  `UNIX_LIKE_FOSS`, which means "Unix-like desktop environment, but FOSS". Includes: Linux and BSD. Excludes: Android (mobile), MacOS (non-FOSS), ChromeOS (non-FOSS). Only affects you if you have created custom [Method](https://wakepy.readthedocs.io/v0.9.0.post1/api-reference.html#wakepy.Method) subclasses.  ([#379](https://github.com/fohrloop/wakepy/pull/379))
