The Binding Of Isaac Repentance
The Binding Of Isaac Repentance DualShockers

Repentance, the final expansion pack The Binding of Isaac, was launched a few days ago. As you would expect from games nowadays, the DLC also added dozens of bugs so its developer, Nicalis, Inc, released a small patch to fix them. It also makes some balancing changes for both Normal and Hard modes.

First, you can now find max-level shops easier with a 50% higher rate in Hard mode. But the change would revert back in Normal mode. Second, tinted rocks are now more common in Hard mode, and as usual, the change would revert back in Normal mode.

And third, shops now have Restock Machines that can replace Donation Machines with a 25% chance. The rest of the changes are bug fixes and you can read about them in detail below.
