https://github.com/PennyLaneAI/catalyst/actions/runs/11729023698 these wheels do not contain zstd. The cache must be purged for this change to take effect.

What was the reason to set it to FORCE_ON?

Thanks Erick. No issue by me.
Do we know the size difference of the wheels with this change?

[jay-selby]

Looks good. Thanks Erick for handling this quickly

Do we know the size difference of the wheels with this change?

@mlxd : Looks like just 1 MB. It could have been more if we removed both zlib and zstd. But keeping zlib makes the difference very small.
