Subject:   New SAXON release 4.4

A new release of the SAXON XSL interpreter and compiler (version 4.4) is available, at a new URL: http://users.iclway.co.uk/mhkay/saxon/.

I decided that with the new July 9 spec out, it was a good time to checkpoint. This release has very few new features but greatly improved performance. It still implements the April 21 specification.

As an example of the performance boost, Oren Ben-Kiki's 8-queens stylesheet previously took 75 seconds when interpreted and 21 seconds when compiled. It now takes 12 seconds interpreted and 8.5 seconds compiled.

For stylesheets that are less computationally intensive the saving is smaller, but still significant. One note of caution however: for simple stylesheets that do little more than a single serial pass through the source document, the benefit of compiling is now very small.

[PS: there's now a packaged version of the SAXON 4.4 XSL interpreter on the web site at http://users.iclway.co.uk/mhkay/saxon/ under the name "Instant SAXON". Designed for ease of installation and execution, it packages up the interpreter, complete with an XML parser (Ælfred) as a Windows executable. Thanks to James Clark for giving me the idea!
