Released 15 September 2020

Patches work only with the immediate previous version.

Bleeding Edge Builds

Bleeding Edge builds are more stable than Beta versions, but not as stable and battle-tested like Production Ready builds.

With Bleeding Edge builds, you get access to newer features and enhancements faster. You can also provide early feedback for new features before they get rolled into the Production Ready builds.

Bleeding Edge builds install side-by-side with Production Ready builds, so you can safely install both without the newer builds affecting your normal work.

Please note files saved with Bleeding Edge builds may not open in older Production Ready builds.

What's new in Gaea

While most of the focus has been on bug fixes and more stability, we've added a few new features like collapsible nodes, the new Fx node, and a pixel-based ZeroBorders mode for complete precision.

The way we work with portals and how we connect nodes has a whole new aspect with the new menus. See

Further details forthcoming.
