If you look at the website there is summary in the Current/Final copy.
"All COVID-19 related executive orders, administrative regulations, other directives issued by the Governor or pursuant to his authority, or agencies or boards under the Governor's authority, not specifically extended by this Act are of no further force or effect as of the effective date of this Act."
I don't think the mask mandate was included in this bill, so under this logic it should be null.
Passed on the 30th, so why isn't anyone talking about it I wonder?
Maybe I don't understand how the process work and it takes time to implement or something, or the media just doesn't want to talk about it.
Here's the link to the Joint Resolution.
EDIT: Sorry not a bill, a Joint Resolution.
