10 curated breaking changes across major versions of airbnb/lottie-ios. Use this as a migration checklist before bumping dependencies.
The new Core Animation rendering engine ([first introduced in Lottie 3.4.0](https://github.com/airbnb/lottie-ios/discussions/1627)) is now enabled by default for supported animations.
Specifically, `LottieConfiguration.shared.renderingEngine` now defaults to `.automatic` instead of `.mainThread`. Animations that use features which are not supported by the Core Animation rendering engine will automatically fall back to using the original Main Thread rendering engine.
When using the Core Animation rendering engine, Lottie animations now always animate smoothly regardless of the amount of work being done on the app’s main thread. This **significantly improves animation performance** while also eliminating CPU overhead.
If you encounter any compatibility issues when using `RenderingEngineOption.automatic`, please file an issue with a copy of your animation json.
`DecodingStrategy.dictionaryBased` is now enabled by default
