The ColdFusion 8 Update 1 release is a follow-up to the extraordinarily well received initial release of ColdFusion 8, and includes full support for 64-bit OSs, as well as support for Mac OSX 10.5 ("Leopard") and Windows Server 2020.

We have also added some core language improvements, including nesting of structure and array creation and have made AttributeCollections significantly more powerful, allowing developers to create structures of information that can be re-used from one tag to another.
See the Release Notes for full details and the full list of feature additions.
The ColdFusion 8 release is one of our finest ever, but there is always room for improvement, so in addition to the feature updates, we have also fixed a significant number of reported issues. Take a look at “Issues Fixed in this Release” in the Release Notes for details.
Adobe ColdFusion 8 continues it's UNBELIEVABLE adoption curve without sign of letting up, and we now have the all-OS 64-bit platform support firmly nailed down in 8.0.1.
Nice job team!
