Beta 10 - April 2019

OpenTimelineIO Release v0.10

We have a port to C++ that you can preview on the cxx branch which we will soon land into master. There are also some schema changes we'd like to make, which we'll be working on and presenting to the community after we land the C++ port. If you'd like to read about how that will work:

Breaking Change:

• In anticipation of the C++ port (see the cxx branch: https://github.com/PixarAnimationStudios/OpenTimelineIO/tree/cxx) a number of changes were made to make the python API behave like the C++ one
  • #372 types in Opentime are now immutable
• This led to other enhancements that shouldn't be as noticeable to developers:
  • #477 Timeline.global_start_time had a default value of 0, 24 and was not being serialized. Now it defaults to None and is correctly serializead/deserialized
  • #377 JSON serializer adapter arguments tweaked
  • #364 Using weakref to point at parents
  • #400 the __copy__ method has been removed
