* `expand(ex)` and `expand(module, ex)` have been deprecated in favor of

`Meta.lower(module, ex)` ([#22064, #24278]).

* `ones(A::AbstractArray[, opts...])` and `zeros(A::AbstractArray[, opts...])` methods
453+
have been deprecated. The general replacement is `fill!(similar(A[, opts...]), {1|0})`,
454+
though in most use cases simpler alternatives are better: For `zeros(A)`, consider
455+
`zero(A)`. For `ones(A)` or `zeros(A)`, consider `fill(v, size(A))` for `v` an
456+
appropriate one or zero, `fill!(copy(A), {1|0})`, `ones(size(A))` or
457+
`zeros(size(A))`, or any of the preceding with different element type
458+
and/or shape depending on `opts...`. For an algebraic multiplicative identity,
459+
consider `one(A)` ([#24656]).
460+
452461
* The `Operators` module is deprecated. Instead, import required operators explicitly
453462
from `Base`, e.g. `import Base: +, -, *, /` ([#22251]).
