It comes five months after 1.6, which is not bad. (In the meantime, we also had two small releases in the 1.6 series for compatibility with the latest Boost and Visual C++.) It contains 53 issues and pull requests that you can examine in detail on GitHub; just follow the previous link. The usual git incantation shows that the release consists of 217 commits by 14 people (once you filter out a few duplicates).
Other people were involved by contributing bug reports or patches; their names, as far as I could find them, are in the list of change for the release. I hope I didn’t miss anyone; if so, I apologize.
There are two new features I’d like to point out in particular. Both are disabled by default, as they cause a performance penalty. The first is the addition of a time to the Date class; this makes it possible to finally price intraday options. The second is a reimplementation of the Observer pattern that makes it safe to use from C# or Java, whose garbage collector had a habit of sometime destroying objects during notification and crashing the whole thing down. Both new features are mostly the work of Klaus Spanderen. You’re encouraged to try them out; the release notes explain how to enable them (look for them at the bottom of the file).
That’s all for this post. See you after Düsseldorf.
