Also worth mentioning, new versions of Mazes & Minotaurs which is vaguely OSR-ish but not directly compatible with old D&D
A Paladin in Hell - I started playing D&D in 1978, when the PHB had just come out. My first GM was my friend's older brother in college who had the OD&D books and used them to GM. I was mesmerized by the PHB, in particular the picture of A Paladin in Hell and my first character was a paladin .
Apparently running out of ideas, TSR decided to turn that picture into a module. It's not terrible, but not what I pictured either. $4.99, 64 pages.
AC9: Creature Catalog - As a kid, Basic D&D always reminded me of when we'd go over into Illinois. Everything was slightly different, but almost the same. This is even more true in the monsters, which are often familiar but not quite the same. And many that are just completely new. $4.99, 96 pages.
I9 Day of Al-Akkbar - Desert themed module, more Arabian than Egyptian. 40 pages, $4.99
RR2 Book of Crypts - Bunch of Ravenloft adventures. 96 pages, $4.99
The Witch: Aiseilgh Tradition for S&W - New class and new spells for S&W complte. PWYW, 22 pages.
Friday Freebie Enhanced Map 2-03-2017 - Lots of 45 degree rooms and corridors, which you saw in the very early dungeons (especially Dave Arneson's in Blackmoor from JG) but not much since. $1 for enhanced version.
Nod 31 - Some people can write well and some people can write fast. John Stater can do both. Here's another issue of his 'zine complete with hex crawl with a Roman flavor, new classes, new monsters and probably a lot more. 151 pages and $3.99
