Hi, I'm the creator of Anime.js. Firstly, thank you for the submission. I honestly didn't anticipate being featured on the homepage of HN without any major update to the library! To those wondering why the project hasn't been updated recently, it's simply because I've been working on a new version (V4) for the last two years. The core library has been completely rewritten, I'm currently in the testing and documentation phase and should be ready for release by this summer.

Some of the new features of V4 include:

* Improved performance: The library has been entirely rewritten with performance optimization and low memory usage in mind.

* New ESM Module first API: Import only what you need and benefit from improved tree shaking.

* Better timelines: New options for animation positioning, allowing looping animations in timelines and improved parameters inheritance.

* Additive animations: A new tween composition mode that lets you smoothly blend concurrently running animations.

* Variable framerate: Specify different framerates for each animation or set it globally.

* New callbacks: onTick, onLoop, onRender, etc.

* Value modifiers: A function to modify or alter the behavior of the numerical values of the animated property value before rendering.

* Animate from: Animation from a given value to the current target value.

* Improved documentation: A new design with enhanced animations demos and more in-depth explanations.

* Unit tests

And much more! I can't wait to share it with you!
