This release works much better on Vista and Windows 7.
It has improvements in international character set handling. It handles path names longer than 260 characters. It has support for IPv6. It allows multiple Cygwin installations to exist on the same machine. It breaks backwards compatibility with some older applications. It no longer works on Windows 9x class systems.
This release fixes problems with running 16-bit
applications on Windows 9x, using a //share as a
home directory, and CTRL-C inappropriately killing
background processes. It also now provides some
new math functions and has a minor speedup for
some pthread functions.
