What I Like

• I’m really excited about CF9′s support for Object Relational Modeling. I think thorough testing must take place to make sure it scales properly under load. I imagine it’s solid since it’s based on Hybernate, but I’ve seen a few promising ORM frameworks flame out before they had a chance to be adopted due to their inability to scale.
• Access to server variables is also good. There is nothing worse than having to create service initializer hacks to pre-cache components in a clustered load balanced environment (think 4 physical boxes with 7 instances each) after server/instance restarts.
• Multi-server admin tools. Enough said.
• Although I prefer to code JavaScript applications separately from CFML, I am glad Ext-JS (3.0) continues to be the official JavaScript framework that ships with ColdFusion.

Not so Hot

I don’t think the new “local” scope adds any value. It seems we’re trying to hard to allow people to write inefficient code by being careless about scoping. Using “var” is fine with me as it is similar across multiple languages. “local” will just add another thing to remember when coding in CFML.

The Jury is Still Out

I’d like to get more testing done with the IDE, ColdFusion Builder, before making up my mind. I’ve been a fan of Aptana, the Eclipse-based IDE, for working with my favorite JavaScript frameworks, PHP and HTML/CSS. I hope the tool is both capable and fast, which has been tough to achieve with Flex Builder.
