Long-time Mac software developer Panic will be launching a major new version of its web-coding tool, now called Coda 2, along with an iPad companion app called Diet Coda on Thursday. The company describes Coda 2 as an "overhaul of every facet" of the editor, while Diet Coda is seen as a portable tool for making quick fixes to code when a developer is on-the-go. Both programs will be sold at half-price on Thursday, May 24 only.
