Beta 12 - March 2020

This is the first release with the C++ core. Please test the new build system and make sure it works for your needs. If you run into issues, pin to 0.11.0 (the last pure python release) and let us know so that we can address them.

The adapters remain in python, but the core library and algorithms are implemented in C++. For more information you can see this pr:
#540

Big Changes:

• C++ Core: the core of opentimelineio is now pybind11-wrapped C++. (see above)
• otiopluginfo command was added for printing information about plugins visible to otio: #586
• Kdenlive adapter included in contrib (thanks @vpinon) #618
• Also includes preliminary swift bindings

Small Changes:

• Tweaks to the repo in anticipation of the move to being hosted by the Academy Software Foundation
• hook function arguments are passable to all commandline scripts (@mikekoetter) #651
• Documention for the C++ core, debugging and building
• local manifests are loaded so that they override the internal manifests for plugins (@JoshBurnell) #591
• Lots of upgrades for the AAF adapter (@JoshBurnell)
• SchemaDefs now have a repr method #566
• CMX EDL Adapter supports multiple locaters per clip now (@elabrosseRodeofx) #664

Lots of other small fixes and changes. Thank you to all of the community contributors!

Beta 11 - July 2019

This release is a final checkpoint before we land the C++ branch (cxx) into the master branch. We found there were a number of other small changes that needed to be made before the CXX and Master branches were ready to be merged, so we needed to do one more release before we did that.

Big Changes:

• The CXX branch is now up to date with master and will be landed shortly after we make this release. (#528)
• In keeping with the VFX platform, we've dropped support for python 3.5 and added support for python 3.7 in our unit test and CI system. (#526)

Small Changes:

• AAF bugfixes by @freesonluxo (#517, #518, #512, #493)
• Autogenerated schema documentation + unit test for detecting schema changes (#521)
• FCP XML bugfixes by @reinecke (#494)

Big thanks go to @andrewmoore-nz and @thecargocultnz for all the very detailed bug reports and repro cases, they are very helpful for improving OTIO robustness!

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:
https://opentimelineio.readthedocs.io/en/latest/tutorials/wrapping-otio.html

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

Big Changes:

• #497, #488 Enhancements to Dropframe support in Opentime (@apetrynet and @reinecke)
• #450 Hookscript plugins now have arguments passed in (@mikekoetter)

Beta 9 - November 2018

OpenTimelineIO Release v0.9

Big Changes:

• #309 FCP X XML adapter (thanks @eric-with-a-c)
• New plugins:
  • #351 HookScripts: let you run code in between steps in the OTIO execution flow
  • #342 SchemaDefs: add your own proprietary schemas to OTIO (for example, for a custom metadata class specific to your studio) (@peachey)
• #342 UnknownSchema: If OTIO hits a schema it doesn't recognize, it doesn't trigger a parse error, instead a blind object is constructed and carried along. (@peachey)
• #312 Documentation for OTIO now lives on readthedocs: https://opentimelineio.readthedocs.io/en/latest/index.html (big thanks to @boredstiff)
• Optimizations:
  • #357 Tracks now maintain a set to improve 'contains' performance, resulting in (in some cases) 50x speedup for constructing tracks with lots of clips (thanks @rogergodspeed)
  • #358 Added range_of_all_children to return a dictionary of all the ranges of children of a track in the space of the parent (equivalent to range_in_parent). This sped up the flatten algorithm considerably.

Small Changes:

• #335, #325, #301 Improvements to the AAF reader (including support for handling muted clips)
• #299 Now commandline tools are organized into a 'console' module so that pip install correctly installs them
• #355 otioview, otioconvert and otiocat grew a commandline argument to disable the medialinker -m none
• #291 Builds now also include Python 3.6, to keep up with the VFX platform. (@boredstiff)

otioview:

• #302 otioview now has a number of keyboard shortcuts that make it easier to navigate (@bonpix)
• #321 Dark mode for otioview (@boredstiff)

As usual, other small fixes and improvements.
