MnP made the 'other featured titles' section in the latest DriveThruRPG/RPGNow newsletter (quoting it here because when this happened with BLUEHOLME™ I missed it, and they don't seem to archive their newsletters):
Mazes & Perils Deluxe Edition
by Moebius Adventures
SYSTEM: Dungeons & Dragons
The Mazes & Perils (MnP) roleplaying game takes a page from the first wave of the Old School Renaissance (OSR), back when it wasn’t "old" at all…
Inspired by the 1977 “Holmes” edition of the world’s most popular roleplaying game, MnP eschews pages and pages of rules for a simpler time when house rules were the order of the day.
First released in 2012, MnP drew a line on the map of OSR retroclones, being something easy to pick up and play. There are no superpowers here. Fighters have swords and armor. Clerics have their faith. Thieves skulk in the shadows. And Magic-Users sling magics at their foes until they run out of spells. This style of gaming is about grit and wit — and if your character dies, it's time to roll up a new one.
The original book was awarded a Gold Ennie Award in 2013 for "Best Free RPG," and now we've updated it with even more great content!
Now in 2016, we have been working on a new version of MnP, with some new classes, new spells, new optional rules, and a new look! Mazes & Perils Deluxe offers everything you liked about the original with a new coat of paint and a few new tools in the toolbox!
New Class – The Enchanter – along with 20+ new spells in his arsenal
New Class – The Shaman – along with nearly 20 new spells of his own
Rules for Variable Damage for Weapons and Variable Hit Dice
New layout, more art, and plenty of editing
Come check out a blast from the past and see why OSR is alive and well!
$7.99
Sorry for anyone who missed the $1 introductory price - you guys need to be quicker on the draw!

I like the Dyson dungeon map in the new version, but I haven't had a chance to really compare the old vs. the new yet (waiting for a chance to get to the office printer!). You or Moebius Adventures should post a comparison somewhere, Vince - or is there one already, and I missed it?
I have a stack of games lined up that I want to run, but hopefully someone will run a session or two of MnP online somewhere so I can try it out.
