ODB 2.5.0 beta available Mar 19, 2019
The latest 2.5.0 beta of the ODB compiler and runtime libraries can now be built and installed on all the major platforms (Linux, Windows, and Mac OS) from source packages available in the build2 cppget.org repository.
build2 0.10.0 released Mar 19, 2019

build2 — C++ Build Toolchain February 3, 2016
build2 is an open source, cross-platform toolchain for building and packaging C++ code. It includes a build system, package manager, and repository web interface. We've also started cppget.org, a public repository of open source C++ packages.

This is the first alpha release and currently it is more of a technology preview rather than anything that is ready for production.
