Mexico's Senate voted 59-25 today to approve the law. As I understand 
it, it will become official after the president signs it (which is 
expected, as it's his idea) and its official publication. Assuming that 
happens we can cite the publication and install the patch into TZDB. 
Although this wouldn't affect timestamps until 2023-03-19, we'd need a 
new TZDB release well before then to give time for the data to percolate 
downstream.

I haven't heard anything about Paraguay recently. If Paraguay is also 
changing its rules effective March 2023 it'd be nice to get that in the 
next TZDB release as well. But I suppose we shouldn't wait too long for 
Paraguay to decide.

Here's coverage of the Mexican Senate vote:
