* The unexported type `AbstractIOBuffer` has been renamed to `GenericIOBuffer` ([#17360] [#22796]).

* Remaining vectorized methods over `SparseVector`s, particularly `floor`, `ceil`,
`trunc`, `round`, and most common transcendental functions such as `exp`, `log`, and
`sin` variants, have been deprecated in favor of dot-syntax ([#22961]).

* The method `String(io::IOBuffer)` is deprecated to `String(take!(copy(io)))` ([#21438]).

* The function `readstring` is deprecated in favor of `read(io, String)` ([#22793])

we could also deprecate this macro? (or remove if not used outside of base)

Absolutely, chances are most of the Xmap_YZ macros/functions for SparseVectors can be cleaned out with some care :). Would a separate pull request be alright?
