However, we (that means mostly Nick) have also made a large number of bug fixes and stability improvements across many platforms. Many thanks to everyone who helped by providing bug reports and patches including Brodie Thiesfield, Dagobert Michelsen, Evan Jones, Joachim Bauch, Pavel Plesov, Roman Puls, Sebastian Hahn, William Ahern, Yasuoka Masahiko and Zhuang Yuyao.
In a separate email, Nick also provided a much more verbose description of what all changed.
