Macromedia today released an update for Dreamweaver MX 2004.

The company says the update offers substantial performance and stability improvements over the previous version. "With this updater, Dreamweaver MX 2004 increases end-user productivity by enhancing key workflows and improving the performance of the application," the company says.

Macromedia says that the application gains significant speed enhancements, promising "performance gains of up to 50 per cent on Windows and up to 70 per cent on Mac OS X".

Updated trial versions and evaluation guides for the Studio MX 2004 products are available now.

Customers with previously expired trial versions of Dreamweaver MX 2004 will be able to test the new version for another trial period.

Macromedia is also modifying its existing upgrade policy for certain products. The new policy permits a Studio MX 2004 product upgrader to use the prior version of the product on the same computer as the upgraded version. An additional policy change has also been made that gives developers limited rights to distribute their own Macromedia Flash components based on those included with the MX 2004 products.

Additional details regarding license changes are available online.
