Hi all, I just finished the newest MSM version. Unfortunately, I'm afraid I'm a bit late to get it shipped with boost v1.43 but at least it will give us time to have a look at it. What is new: - the doc was rewritten almost from the ground up. - internal transitions: for all front-ends, and both ways: either in the transition table or inside state's internal transition tables - more row types (yes, even more) allowing actions to be defined in state machines or in states The last 2 points aim at making states more useful - some performance gain - new eUML syntax to get rid of parens and to better support attributes - policy for better compile-time at cost of dispatch speed. And a few minor improvements. It was not possible to implement every wish and excellent idea offered during the review at this point, but they are in no way forgotten and I do not intend to stop development now. I'm interested in any comments, especially about the doc, which, like everything new, probably is not perfect but I hope, still an improvement. You can find the new version, like always: - in the Vault (http://www.boostpro.com/vault/index.php?directory=Msm) - in the sandbox (http://svn.boost.org/svn/boost/sandbox/msm/) Regards, Christophe
