A software release is like what Microsoft is pushing with Windows 7.
It is a new version of the software that often improves the functionality of the current releases that most companies are operating on and it works out the bugs with the technology in the older releases.
It is generally a good thing for software vendors.
My company has used PEAK technology for a portion of our IS needs in production area. It has been in use for 10+ years.
I am in IS, but my background is in Operations. So, I am very familiar with what the company is speaking about. Of course, I am making a huge assumption they are speaking in normal IS speak here when they say release.
I'd be more interested in their current client base, liscensing fees per client, and upcoming sales in the sales channel. That is more important than a new release. If I build a 'new and improved' product, but can't sell it; it is still worth nothing.
