A gallery of the Psychic Powers available are here. Not as good as last edition where you just had to roll under a leadership of 10(mostly), though comparing each army to each other an army with 30 warp charges versus one psyker is better at denying, but even then it doesn't guarantee anything.

Psychic powers are now rolled using a dice pool instead of just a successful leadership test. Psychic Power Overhaul - Instead of using Psychic powers in the movement and shooting phases they are now called upon during the new Psychic phase.

These rules are mostly to the benefit of armies that must Challenge, such as Chaos Space Marines. Challenge Changes - Overkill wounds from a challenge can spill into a general Assault, while a "solo" model in a challenge can be attacked by models not in said Challenge.7th ended this fuckery, only to replace it with Invisibility. No more Monsterstars - In 6th, Independent Characters could join a Monstrous Creature that could be taken "as part of a unit." This meant Shadowsun could join a Riptide to grant it Stealth, Shrouded, and improved Jetpack speed.On the flipside, expect arguments with That Guy over which model is "the closest" while Monstrous Creatures don't particularly care about these rules!

On the upside, this system does allow for basic flanking to matter, avoids the 50% cover shenanigans of 5th, and units are somewhat protected by the fact that models out of range or LOS cannot be killed.

It definitely had big game changers and multiple smaller changes that warranted calling it a new edition. Some have suggested that the community should consider it "6th Revised" or "6.5," but Games Workshop stopped using edition numbers with 6th, so we'll probably never know (the errata and FAQ docs specifically refer to the new version as 7th edition). It was basically an extension of the 3rd edition ruleset, as with every edition of the game since 3rd, and, more specifically, it's an extension of the 6th edition ruleset (which it replaced after only two years). Warhammer 40,000 7th Edition was released May 24th 2014. The fact that it's the Dark Angels in the cover again is just awesome.
