Hi folks, I have some exciting news to share. Julian has graciously offered and I have accepted to become the lead maintainer for Velocity. I'm really excited to be working closely with and learning from him in order to transition this project onto my plate. I remember when Julian started working on Velocity (locked away in his apartment — a few blocks away from me). Then later when he first announced it publicly. And finally when it exploded in growth from 0 to what it is today. I hope to bring that same enthusiasm, energy, and skill to it. I am honored to be taking it on. Looking forward to working on it along with the rest of the contributors.

Updates

1.4: Pause / Resume (per element or global).
Forcefed string animation (just have matching number spaces) including unit conversions and colour names (ie background:["rgba(red,0.1)", "blue"]). High resolution timers (animations should be slightly smoother).
Various fixes including ticker (loading Velocity in a background window) and color handling.
1.3: Code cleanup - no breaking changes known.
1.2: Custom tweens. Custom easings. "Finish" command.
1.0: File name changed to velocity.js. Read VelocityJS.org/#dependencies.
0.1: stop now stops animations immediately (instead of only clearing the remainder of the animation queue). No other backwards-incompatible changes were made.

Comparisons

CSS transitions are meant for simple interface flourishes.
jQuery's $.animate() is slow and poorly-equipped for motion design.
Velocity is a fast, feature-rich standalone alternative to jQuery's $.animate().
