Basically, the change is gate strength must be 16kn (3600lbs).
That's sideways and pressing in as well as pressing out on a carabiner!
New ANSI Quote:
New Design, Stronger Gate
One of the major additions to the Z359.1 Standard is new gate strength requirements. Under the new standard, snap hooks and carabiners must meet the following:
• Gate Face must withstand a load of 3,600 lbs. (up from 220 lbs.)
• Side of Gate must withstand a load of 3,600 lbs. (up from 350 lbs.)
• Minor Axis of a snap hook or carabiner, except those with captive eyes, must withstand 3,600 lbs.
• Tensile load for the snap hook or carabiner must withstand 5,000 lbs. (same as current)

This one has the information pertaining to testing, also screw gates are definately out as carabiners must be self locking.

III. Proposed Changes to ANSI Z359.1 Section 3.2.1.4
The proposed changes to the section of ANSI Z359.1 dealing with gate hook strength are detailed as
follows: 7 Snap hooks and carabiners shall be self-closing and self-locking and shall be capable of
being opened only by at least two consecutive deliberate actions. When tested in accordance with
4.3.1.1.1, snap hooks and carabiners shall be capable of withstanding a 5,000 pound (22.2kN)
tensile load without breaking or distortion sufficient to release the gate. When tested in accordance
with 4.3.1.1.2, the gate of a snap hook or carabiner shall be capable of withstanding a minimum load
of 3,600 pounds (16kN) without the gate separating from the nose of the snap hook or carabiner
body by more than 0.125 inches (3.1mm). When tested in accordance with 4.3.1.1.3 the gate of the
snap hook or carabiner shall be capable of withstanding a minimum side load of 3,600 pounds
(16kN) applied to a point midway between the nose and gate hinge without breaking, permanent
deformation greater than 0.125 inches (3.1mm), or separating from the nose of the snap hook or
carabiner body by more than 0.125 inches (3.1mm). When tested in accordance with 4.3.1.1.4 the
gate of the snap hook or carabiner shall be capable of withstanding a minimum minor axis load of
3,600 pounds (16kN) applied to a point midway between the nose and gate hinge without breaking
or distortion sufficient to release the gate.

And more, this shows that a carabiner must be able to take 3600lbs from the inside pressing out.

I would conclude most current carabiners would fail the test.
