AcademySoftwareFoundation/OpenTimelineIO 发布 Beta 16 - April 2024

## Summary This release moves from the third party any and optional to C++17 `std::any` and `std::optional` (by @darbyjohnston) as well as a collection of enhancements in how the python bindings handle type conversion with C++ (by @JeanChristopheMorinPerso) and the addition of `comment` to the `Marker` schema (by @nickblt). This release also includes an [experimental set of editing commands](https://github.com/AcademySoftwareFoundation/OpenTimelineIO/pull/1654) (by @ggarra13) in C++. These are a new set of APIs intended to implement some common editing commands (insert, overwrite, roll, etc.) backed by the OpenTimelineIO data model. These APIs are meant to provide an opportunity to try the concepts and form a base to iterate on, however there may be breaking changes as they evolve. ## Important Note About Adapters **This will be the last release to include the full set of adapters.** In the next release, most of the adapters [will move out into their own PyPI packages](https://github.com/AcademySoftwareFoundation/OpenTimelineIO/issues/1386) as optional plugins. **tl;dr - if you rely on the adapters, please use the `OpenTimelineIO-Plugins` PyPI package to ensure you continue to receive them after this release.** The OpenTimelineIO native file format adapters will still be present in the `opentimelineio` python package. These adapters are: - otio_json - otiod - otioz To get the full set of OTIO adapters, use the [OpenTimelineIO-Plugins ](https://pypi.org/project/OpenTimelineIO-Plugins/) python package. In addition to the OpenTimelineIO native adapters, you'll also get: - AAF - ale - burnins - cmx_3600 - fcp_xml - fcpx_xml - hls_playlist - maya_sequencer - svg - xges The following are not included in the OTIO-maintained top-level packages: - kdenlive - Now hosted and supported under the [KDE repository](https://invent.kde.org/multimedia/kdenlive-opentimelineio) - rv_session - This adapter was made obsolete by first-party support of OpenTimelineIO in [Shotgrid RV](https://www.shotgridsoftware.com/rv/) and [OpenRV](https://github.com/AcademySoftwareFoundation/OpenRV) To experiment with what this looks at, check out the [0.17.0 Pre-Release](https://github.com/AcademySoftwareFoundation/OpenTimelineIO/releases/tag/v0.17.0.dev1) - packages are provided on PyPI to try out. ## Big Changes * Remove
