Release 1.4.4 traps some errors in the Arrhenius fitting code and adds additional checking to the user feedback form.

Release 1.4.3 improves browser compatibility for the plotting applet. Changes to the fitting software should make the server more stable. Reports of problems with specific browsers are appreciated.

Release 1.4.2 incorporated a number of bug fixes and introduces a new plotting applet which represents an improvement over the previous capability. Other changes improve the stability of the server and the handling of user feedback. Please let us know if your have any difficulty with any aspect of this release.
