4.0.1

This patch release resolves some missed warnings in 4.0.0 and fixes a broken test on iOS 13+14.

4.0.0

This major release drops official support for Bazel and iOS 9.

3.0.0

This major release drops official support for iOS 8.

Non-source changes

2.0.0

This major release upgrades the bazel dependencies and workspace. This change is breaking for anyone using bazel to build this library. In order to use this library with bazel, you will also need to upgrade your workspace versions to match the ones now used in this library's WORKSPACE file.

Source changes

Non-source changes

1.6.0

This patch release introduces a compatibility initializer for creating Objective-C animation traits from C-style motion timings.

Source changes

API changes

Auto-generated by running:

apidiff origin/stable release-candidate objc src/MotionInterchange.h

MDMAnimationTraits(Legacy)

new method: -initWithMotionTiming: in MDMAnimationTraits(Legacy)

new category: MDMAnimationTraits(Legacy)

1.5.0

This minor release introduces new Objective-C APIs for creating and storing animation traits.

New deprecations

All of the original C-style APIs for animation timing are now informally deprecated. We will remove these APIs in the future.

New features

New Objective-C APIs for storing animation traits.

Old API New API Rationale
MotionTiming AnimationTraits This structure is intended to describe animations only, not motion in general.
MotionCurve TimingCurve This brings the API name closer to the similarly-purposed CAMediaTimingFunction. MotionCurve could also be easily confused with motion through x/y space rather than through time (e.g. ArcMove), which will be problematic as we start defining paths of motion through space.
MotionRepetition RepetitionTraits This aligns the naming with AnimationTraits.
