## [1.4.0] - 2022-08-06
This release is a face-lift for the PSSH class with a moderate amount of Cdm and Serve interface changes.
You will likely need to make a moderate amount of changes in your client code, please study the changelog.
Please note that while it was always privatized as `_sessions`, accessing the Session directly for any purpose was
never recommended or supported. With v1.4.0, there will be drastic problems if you continue to do so. One of the
few reasons to do that was to get the license keys which is no longer required with CDMs new `get_keys()` method.
RemoteCdm minimum supported Serve API version is now v1.4.0.
### Added
- The PSSH class now has a `new()` method to craft a new PSSH box. The box can be crafted from arbitrary init_data
and/or key_ids. If only key_ids is supplied a new Widevine Cenc Header will be created and the key IDs will be put
into it. This allows you to make compliant v0 or v1 boxes with as little data as just a Key ID.
- The PSSH class now has `dump()` and `dumps()` methods to serialize the data as binary or base64 respectively. It will
be serialized as a pymp4 PSSH box, ready to be used in an MP4 file.
- Cdm now has a method `get_keys()` to get the keys of the loaded license. This is the alternative to manually
accessing the keys by navigating the `_sessions` class instance variable.
- Serve API now also has a `/get_keys` endpoint to call the `get_keys()` method of the underlying Cdm session.
### Changed
- Cdm and RemoteCdm now expect a PSSH object as the `init_data` param for `get_license_challenge`. You can no longer
provide it anything else, that includes base64 or bytes form. It must be a PSSH object.
- Serve no longer returns license keys in the response of the `/keys` endpoint.
- Serve has changed the endpoint `/challenge` to `/get_license_challenge` and `/keys` to `/parse_license`. This is to
be consistent with the method names of the underlying Cdm class.
- The PSSH class has been reworked from being a static helper class to a proper PSSH class.
- PSSH.from_playready_pssh is now a class method and returns as a PSSH object.
### Removed
- PSSH.get_as_box has been removed and merged into the PSSH constructor.
- PSSH.from_key_ids has been removed entirely, you should now use `PSSH.new(key_ids=...)` instead.
- All uses of a local Session() object has been removed from RemoteCdm. The session is now fully controlled by the
remote API and de-synchronization by external alteration or unexpected exceptions is no longer a possibility.
### Fixed
- Various uses of the `key_ids` field of WidevinePsshData proto has been fixed in the PSSH class.
- Fixed a few Serve API crashes in edge cases with improved error handling on Cdm method calls.
