Yes.  Matrix 1.7-0 *has* been on CRAN now for while
(i.e. 'March' has remained as announced), *but*
-- because of the ABI change and the problem it can cause for
   *some* users --

we have made it  'Depends: R (>= 4.4.0)'
i.e., you *see* the new Matrix only once you use R 4.4.0
which has been available as "alpha" already and is now in
"beta" already, e.g.,

  R version 4.4.0 beta (2024-04-10 r86393) -- "Puppy Cup"


Best regards,
Martin
