From what I've heard, it's a scripting language similar to PHP but not free.

New ColdFusion Server 5 tags
ColdFusion developers can maintain productivity when working with new and updated ColdFusion Server 5 tags. All core editor features such as Tag Editors, Tag Insight, and Tag Inspector now have full, integrated support for new tags—such as CFGRAPH and CFLOG—and updated tags such as CFINSERT and CFQUERY. There is also a new toolbar for CFGRAPH, with one button for each of the graph types.
   
 ColdFusion Custom Tags
Maximize productivity and code reuse across the team and within the ColdFusion community using Custom Tags. Utilize the new Custom Tag Wizard to more easily write custom tags, and to specify required attributes and default attribute values. Tag Insight and Tag Inspector will then assist you in creating and editing these custom tags.  
 
   
 XHTML Support
XHTML Support, based on the W3C specifications for XHTML 1.0, allows developers to build pages with the latest web technologies, and the extensibility of XHTML gives them the flexibility to incorporate new ideas for Web communication and presentation as they emerge.
   
 Secondary Files tab
The new Secondary Files tab allows developers to browse local and remote files simultaneously and to drag and drop files between the two Files tabs, giving them greater efficiency in accessing and incorporating documents and images.
   
 Folder Deployment
New Folder Deployment settings allow developers to determine the deployment method for individual folders and files within a project. These new settings make deployment much more accessible to the novice user while maintaining the sophistication of the feature for the high-end user.
 
   
 Macromedia Fireworks Integration
Improve your workflow across applications through tighter integration with Macromedia Fireworks. Launch Fireworks to edit graphics by selecting the image in the Editor, Files pane, or Thumbnail Viewer.
   
 Auto Backup
Auto Backup gives developers the assurance that their hard work will always be preserved. Auto Backup is a new user-configurable option to auto-save files at a certain time interval and to recover and restore files that have been backed up.
   
 Full-Size Help Browser
Save time looking for correct tag syntax with the integrated Tag Help. You can now access help from within the Editor (press F1 while highlighting a tag) via a full-sized browser dedicated to displaying tag help.
   
 Double Byte Character Support
Build web sites for the whole world to access. Developers now have the added flexibility to create pages with characters that require double-byte support, including Japanese and Korean.
   
 Secure FTP
Get advanced security when transferring files to your server via FTP. You can now FTP files to a secure server using SSL (Secure Sockets Layer) with 40-bit encryption.


I hope this is more of what you wanted..

hey, shadowcrafter,

i know i'm like a week late but i just joined so forgive my tardiness....

cf studio is basically a custom-write of Allaire's Homesite html text-editor with the addition of cold fusion-centric features that allow you to easily bang out pages that use cf server-side scripting.

it's quite a competent prog (as is Homesite) and offers solid features like code highlighting, tag validation, code snippet library, complete and create boxes for many code features (cf and html) and loads more. it's open about 85% of the time right alongside my ultradev....

you are wise to grab this prog and use it as the need comes up even if you don't move to cold fusion development....

those is my thoughts on it anyway!! drop me a line if you want more from me.....
