Use this phrase to start a discussion about something that happened in the news or within your social circle. Here's an example of the second type:
Did you hear about Kylie getting engaged? I can't believe it!
You can use "Did you hear about ___" even if you strongly suspect that the listener has heard the news. But not if you know they've heard it.
When the news is someone's action, you use "someone doing something":
Did you hear about them getting arrested?
But you can also replace this part of the phrase with a noun:
Did you hear about the Nuclear Security Summit?
When you make some changes to something, you have created a new "version" of it. For example, if you draw 5 pictures of the same person at around the same time, each picture that you drew was a "version" of that drawing.
In the case of software, companies add new features and fix problems with their software. They release these changes to their customers as a new "version". The new version usually has a new name or a number (like "Microsoft Word 2007", "Adobe Photoshop CS4", etc.).
When a company "introduces" a new product, it tells the general public that the product will be available.
You can use the phrase "___ introduced ___" if the company has started just selling the product. You can also use it if the company just announced that they were going to release the product:
They just introduced a new ultra-flat-screen TV at the Consumer Electronics Conference which is supposed to be available later this year.
Notice that this phrase is followed by the singular ("introduced a new ultra-flat-screen TV ") instead of the plural ("introduced new ultra-flat-screen TVs").
