All -

I'm pleased to announce that asio has been accepted into Boost. As
usual with a Boost review, the asio review generated plenty of
discussion, issues, and controversy. Comments ranged from high praise,
including success stories of projects in production, to serious design
concerns and issues. On balance, in my judgment, asio provides a
generally solid library that is ready for inclusion into the Boost
library -- providing key functionality in an area that developers have a
strong need.

Of course, like anything else, asio is not perfect -- a number of key
issues were uncovered during the review. In terms of required changes
I'm only going to cite a few:

- Fixes to dynamic memory allocation issues
- Interface changes to support ipv4 and ipv6 seamlessly at runtime
- Improvements to support strongly typed socket interfaces

Chris has communicated a couple possible solutions to the memory
allocation issue and I'll ask that the interface and other changes for
this issue continue to be discussed on the Boost list so consensus can
be achieved on the best resolution.

Other key improvements that should be explored as future enhancements

- Possible removal of some of the c-style interfaces
- Exploration of higher level iostream integrations
- Performance improvements
- Improved documentation (wouldn't be Boost w/o this one)

Chris has a much longer list of changes garnered from the review and is
well on his way to addressing many of them.

Note that there were several threads and discussions about performance,
which is particularly critical for the domain covered by asio. One of
the performance issues is the dynamic memory allocation issue cited
above. In general, the reviewers have extremely high expectations here.
However, after reviewing the discussion and library it's my belief that
many developers will find asio performance sufficient to build
significant projects with only the memory allocation changes. I expect
Chris will be able to address some of the other performance issues cited
by reviewers in asio over time.

Once again I'll apologize to the Boost community for the delay in the
review results. The delay was entirely due to my own personal
scheduling issues and should not reflect on asio in any way. Thanks
again to all the reviewers for their effort and especially to Chris for
his tremendous effort in bringing asio to Boost!
