Choose an iocaine version

# Stable (iocaine 3.x)

The current - new - stable version is a huge upgrade from the previous version. This is the recommended version to deploy.

It’s a major release, with many breaking changes. Unfortunately, the best way to migrate is likely to start over. Unless you were using Nam-Shub of Enki, because then upgrading that too will be enough.

# Old Stable (iocaine 2.x)

The previous stable version is iocaine 2.5.1, and is deprecated. It continues to work, documentation is still available, but there is no work being done neither on this version of iocaine, nor on its documentation.
