I've nothing much to say other than what it says in the headline: people have reported issues with the ColdFusion 10 update 14 that was released yesterday ("ColdFusion: new security patches for 9.0, 9.0.1, 9.0.2, 10.x, 11.x"):
- "Coldfusion 10 Update 14 pretty much trashed my server..."
- "ColdFusion 10 Update Killed My Admin"
- "Update 14 made our application pool stop working, taking our site offline after a few minutes..."
And if you feel you must install it immediately, as I said yesterday: install it in a test environment and fully regression test your applications first.
Don't just install it on production servers without first testing it. This obviously applies to any change you're thinking of making to the system.
Oh... the ColdFusion Team have also got around to mentioning these new updates on their blog: "Updates for ColdFusion 11, ColdFusion 10 and ColdFusion 9 released". I recommend you go and read the comments and subscribe to the thread so as to stay on top of people's findings, and Adobe's responses.
