You can get newer releases from their page directly, in case anyone wanted to try navicat. It's a pretty good utility, though I personally still like to use the respective SQL server command line utility shells. It's a 30-day trial.

I used Navicat for along time, and its not bad software. These days though I've been using the free "Sequel Pro" for OS X. Does all the same things I need to do, as long as I'm on a mac. http://www.sequelpro.com/

The URL loads a lot of quite clearly non-plain text data served as text/plain. Am I missing something?

Really? It downloads a .dmg for me...

Content-Type is text/plain, Content-Disposition is not set. Your browser overrides content type based on file name "extension", at least for commonly misused types.

Gotcha.

Regardless, it's their software. After all that, it's not even an expiring URL, or obfuscated, or anything.
