For those who don’t follow rec.arts.int-fiction, there is a new release of Inform 7. In addition to fixing over a hundred bugs reported in the previous release, it provides dynamic string handling for the first time, and regular-expression matching.
This means that it’s possible to (for instance) run regular expressions on the player’s command to modify it before parsing; that it’s possible to make any “to say” phrase produce upper-, lower-, title-, or sentence-cased output; and that it’s easier to store and read back text files for use by Glulx.
There are other goodies too.

You folks are steadfast and marvelous. Thanks for the continuous work.
Well done with this release. It seems to be one of the better updates in quite some time. I like all the new examples – lost count of how many there are now.
386, I think, at the last count.
Will there be a new I7 syntax file as well in the near future? There’s been a lot of important changes to the I7 syntax, I think, just from reading the Changelog files themselves.
I updated the syntax document at the same time that the new build was released; try downloading it and you’ll see. (Unless of course somehow the download is broken from somewhere? In which case, let me know. But it should be there.)
