I decided to name v2 version nxslt2, so in the release you will find nxslt2.exe file. That's because I still do lots of .NET 1.1 development and so I need nxslt.exe to remain .NET 1.1 tool. If you don't like nxslt2.exe name - well, just rename it.
Some smart people proposed to contribute patches to the nxslt codebase in order to add new features they need. That's just great. To enable this I moved nxslt sources to the Mvp.Xml Project CVS Repository. Now if you need the nxslt tool to have a new feature you can either just suggest it and wait me to implement it or instead you can checkout nxslt sources, add new feature and send a patch to me. Do whatever works for you and thanks in advance for contributions.
