July? Iirc I read June in the announcement.

I'm not sure about "strict". Yet ...

... this very mail worked out how overlap with larger holiday ranges
could be minimized not only for a single release, but for any as long
as the cadence is followed. Iirc this works out better with 8 months
(as kind of to be expected, as then there are only 3 variants, whereas
with 9 months it would be 4 of them).

Just to clarify, personally I'm fine with 9 months or even longer, but
it seemed to me that we had settled on 8.
