* `eye` has been deprecated in favor of `I` and `Matrix` constructors. Please see the
deprecation warnings for replacement details ([#24438]).

* `zeros(D::Diagonal[, opts...])` has been deprecated ([#24654]).

* Using Bool values directly as indices is now deprecated and will be an error in the future. Convert
them to `Int` before indexing if you intend to access index `1` for `true` and `0` for `false`.
