  1. It came from images

    The Effing origin story: how a production image-rendering framework, a frustrating SaaS detour, and a silly pun turned into an open-source video toolkit.

  2. Effing 0.38.0: cache me if you can

    Effing 0.38.0 adds a persistent image cache for per-frame rendering, plus two fixes: user-space SVG gradients and jitter-free slide motion.

  3. Effing 0.37.0: dev servers, side by side

    Run multiple dev servers without port juggling, plus two canvas fixes: SVG fragments now render, and an honest note about baseline alignment.

  4. Just a quickie

    A short hello: Effing is MIT open source, pre-1.0 but already running in production, and Effing Cloud is in private beta.
