Did the schedule for the meetings go from a bi-weekly to a weekly format?
Also Thursday is the 22nd not the 23rd, i'm a bit confused.

The schedule has not changed from bi-weekly to weekly. However, there are some times when we have one off meetings happen a week after the previous meetings.

I incorrectly had Thursday instead of Friday listed. I fixed it. Thanks!

I think having Istanbul-related client updates first may be good given that will lead into the discussion of the HF block number & testing.

[Souptacular]

Good call @timbeiko. Changing it!

Made some gas estimation of the verification of a Zcash header here.

In short, the call cost to the precompile is 385.000 gas alone, not counting anything else. I could imagine the total cost be something like 600.000 to 1.000.000 gas.
