Stable version

Packages for Debian (and Ubuntu), Gentoo, FreeBSD and NetBSD will soon be available in the distributions. There will also be a Godi package (Godi is a source based distribution of OCaml packages. You should consider using it to simplify the installation if your distribution is missing some OCaml packages).

If you want to compile Lwt from sources, download latest versions from here:
