Boost.Process 0.5 has been released! Documentation and library can be
found at: <>

Why version 0.5?

We have no official process management library in Boost yet. But we had
countless drafts since 2006. In order not to get completely lost between
all those drafts I gave them version numbers. For example, 0.1 was the
very first draft in 2006. 0.31 is the draft documented at
<>. And 0.4 was the draft which was
rejected in a formal review in spring 2011. Version 0.5 is the latest
attempt to create a process management library.

What's new?

Version 0.5 has a very different design than all other drafts before. The
design was proposed by Jeff Flinn who introduced it briefly at BoostCon
2011 when we gave a presentation on Boost.Process. The goals of this new
version are:

* A lightweight implementation (no overly complicated code anymore).
* A fully extensible library (no need for arbitrary "extension points").
* Support for system-level cross-platform concepts only (no Java-like

Other goals like making the library easy to use were of course also
targeted. But these were goals before. The goals above are important as
those things have been criticized in earlier drafts and were as far as I
see the main reasons why version 0.4 had been rejected.

What now?

Please have a look at the documentation and think about whether this
library could fit into Boost. If you have more time, please download and
play around with the new version. Concentrate on the bigger picture: Does
the design make sense? Is it easy to understand? Can you do what you want
to do? Does it look and feel like modern C++?

This is not a formal review. But it would help to get some feedback to see
a tendency. After six years, two Google Summer of Code projects, countless
drafts and still a lot of interest from many people in a process
management library in Boost, we might be able to get somewhere this time.

(If you are on Windows: There is a bug in Boost.Iostreams which has been
fixed in the release candidate 1 of Boost 1.51.0. See the documentation if
you run into a problem when closing pipes.)

Anything missing?

We had a closed beta test in the previous two weeks with about ten people
who had contacted me because of their interest in Boost.Process. I got
already some good feedback and have to change a few details. These are
only details though and shouldn't stop anyone from using this new version
now. If everyone is happy with the overall design and architecture and
it's only details we have to discuss, it's already a huge step forward.

Last but not least: Boost.Process 0.5 wouldn't exist without the help of
Intra2net AG (<>). Intra2net AG sponsored a
project to support the development of Boost.Process. It was this
sponsorship which made it possible to create this new version. Thanks to
