+
+Hot on the heels of v2.5.0, this release brings relief to our Windows
+users. It includes a fix for a 2.5.0 path sanitation change that has been
+confirmed to work on Windows.
+
+To our Windows users: while we don't officially support Windows, we don't
+wish to impede your normal use of Jekyll at all. Our lack of full support
+for Windows is due to our lack of a Windows machine for development testing
+(no one on the core team has a Windows machine upon which to test new
+release candidates), not due to any malice or willful oversight. If you
+come to us with an issue, we are more than happy to work through it with
+you to come to a solution that works for all platforms. Along those lines,
+we have created a [**Windows Test Force**][] (WTF) which is a group of Jekyll
+users dedicated to making sure all future releases work on Windows *before*
+they're released so we don't have this issue again. A special thanks goes
+out to the initial WTF team members, XhmikosR, Julian Thilo, Pedro Rogério,
+and Alfred Xing.
