My husband was nosing about on the internet and came upon this information. Buyer beware, I guess; I can just imagine some lawsuits over non-heat-resistant glass!
"In 1998 Corning relinquished the name "Pyrex," and the helpful new owner has changed the composition of Pyrex products from borosilicate glass to soda-lime glass, which is definitely not heat resistant like the old stuff."

The moral of the story is, read the label. This is from Wikipedia:
Pyrex was originally borosilicate glass. Though borosilicates had been produced before, the name Pyrex is widely used as a genericised trademark for the material. Corning spun off its kitchenware division in 1998 as World Kitchen, Inc. However, Corning retained the Pyrex brand name, licensing it to World Kitchen and other companies that produce Pyrex-branded cookware.
The brand in Europe is currently owned by Arc International Inc. (a French based company) who acquired the European business from Newell Rubbermaid who in turn had acquired it from Corning in the 1990s.[1] Arc International state on their Pyrex website that their versions are borosilicate.[2]
Pyrex kitchen products produced by World Kitchen are no longer made from borosilicate glass, but from soda-lime glass. Their packaging indicates that they must never be used over a flame, on stove tops, under a broiler, or in a toaster oven.

Thanks, Roadsmith, glad I stocked up on the old stuff at various box lot auctions. Why license a name that is synonymous with heat resistant glass and slap it on items that aren't? Ridiculous!

Very important to know, I will hang on to my old stuff forever since I know it works fine. I know I don't read 'instructions' on Pyrex labels since I think I 'know' what it is. What are they going to mess with next?
