Yes. Without hyperbole, The Binding of Isaac: Repentance - v1.7.9B - is the definitive way to play the game if you are on PC.

It is a patch that respects your time. The co-op changes alone are worth the price of admission, allowing veterans to teach newcomers without gimping the run. The stability fixes mean you can finally attempt the "Dead God" achievement (100% completion) without fear of a crash deleting your progress.
While purists might argue that version 1.7.5 was "truer" to the hardcore vision, the vast majority of the Isaac subreddit agrees: v1.7.9B saved the game.
Version 1.7.9B of The Binding of Isaac: Repentance represents a stability and quality-of-life patch rather than a feature update. It addresses lingering bugs from the larger 1.7.8 co-op and balance overhaul, ensures proper unlock conditions, and makes minor buffs to problematic characters like Tainted Lazarus. For most players, the game is considered “complete” and stable at this version, with Nicalis having moved on to other projects (e.g., Mewgenics, The Legend of Bum-bo).
Recommendation: Players should update to v1.7.9B if experiencing crashes in co-op or with Spindown Dice. No need to update for single-player vanilla runs unless seeking maximum stability.
End of report
The Binding of Isaac: Repentance is the definitive version of Edmund McMillen and Nicolas “Nicalis”’s roguelike dungeon crawler. Version 1.7.9B is a minor post-release patch (following the major 1.7.8 update) primarily aimed at bug fixes, stability improvements, and addressing a few lingering balance issues. This report outlines the context of the game, the content of the Repentance expansion, and the specific technical adjustments introduced in v1.7.9B.
Nothing is more devastating than having a 45-minute God-run—Tech X, Brimstone, Sacred Heart—crash during the Delirium or The Beast fight. v1.7.9B specifically targeted memory leak issues that occurred when too many entities (tears, enemies, projectiles) were on screen simultaneously. The patch optimized the game's garbage collection, leading to a noticeable drop in "drunken" slow-motion segments and hard crashes during the "Home" ascent sequence.
While this patch dropped on PC first, it served as the blueprint for the console versions (Switch, PS5, Xbox). If you’ve played Repentance on a handheld recently and noticed smoother frame rates during Hush fights, you have v1.7.9B to thank.
