   so we return only the most recent exception in that case. ([#29901]) (since
   Compat 3.34)
 
-* The methods `Base.include(::Function, ::Module, path)` and
-  `Base.include_string(::Function, ::Module, code[, filename])` have been added. ([#34595]) (since Compat 3.33)
-
-* Implicit keywords arguments or named tuples is supported using the `@compat` macro, e.g. `@compat f(; x, f.p)` and `@compat (; x, f.p)` is equivalent to `f(; x=x, p=f.p)` and `(; x=x, p=f.p)` respectively. ([#34331]) (since Compat 3.32.0)
-
 * Two argument methods `findmax(f, domain)`, `argmax(f, domain)` and the corresponding `min` versions ([#35316], [#41076]) (since Compat 3.31.1)
 
 * `isunordered(x)` returns true if `x` is value that is normally unordered, such as `NaN` or `missing` ([#35316]) (since Compat 3.31.1)
 
 * `get` accepts tuples and numbers ([#41007], [#41032]) (since Compat 3.31)
 
-* `muladd(A,B,z)` now accepts arrays ([#37065]) (since Compat 3.30)
-
 * `@something` and `@coalesce` as short-circuiting versions of `something` and `coalesce` ([#40729]) (since Compat 3.29)
 
-* `NamedTuple(::Pairs)` ([#37454]) (since Compat 3.28)
-
-* `UUID(::UUID)` and `parse(::Type{UUID}, string)` ([#36018] / [#36199]) (since Compat 3.27)
-
-* `cispi(x)` for accurately calculating `cis(pi * x)` ([#38449]) (since Compat 3.25)
-
-* `startswith(s, r::Regex)` and `endswith(s, r::Regex)` ([#29790]) (since Compat 3.24)

-
-* `Dates.canonicalize` can now take a `Period` as an input ([#37391]) (since Compat 3.22)
-
-* Import renaming is available through the `@compat` macro, e.g. `@compat import LinearAlgebra as LA` and
-  `@compat import LinearAlgebra: cholesky as c, lu as l`. *Note:* Import renaming of macros is not
-  supported due to differences in parsing behavior ([#37396]). (since Compat 3.21).
-
-* `Compat.parseatom(text::AbstractString, pos::Integer; filename="none")` parses a single
-  atom from `text` starting at index `pos`. Returns a `Tuple` consisting of the
-  parsed expression and the index to resume parsing from. ([#35243]) (since Compat 3.20)
-
-* `Compat.parseall(text::AbstractString; filename="none")` parses the whole string `text`
-  and returns the parsed expression. ([#35243]) (since Compat 3.20)
-
-* `mul!(C, A, B, alpha, beta)` now performs in-place multiply add ([#29634]). (since Compat 3.19).
-
-* `reinterpret(reshape, T, a::AbstractArray{S})` reinterprets `a` to have eltype `T` while
-  inserting or consuming the first dimension depending on the ratio of `sizeof(T)` and `sizeof(S)`.
-  ([#37559]). (since Compat 3.18)
-
-* The composition operator `∘` now returns a `Compat.ComposedFunction` instead of an anonymous function ([#37517]). (since Compat 3.17)
-
-* New function `addenv` for adding environment mappings into a `Cmd` object, returning the new `Cmd` object ([#37244]). (since Compat 3.16)
-
-* `contains(haystack, needle)` and its one argument partially applied form `contains(haystack)` have been added, it acts like `occursin(needle, haystack)` ([#35132]). (since Compat 3.15)
-
-* `startswith(x)` and `endswith(x)`, returning partially-applied versions of the functions, similar to existing methods like `isequal(x)` ([#35052]). (since Compat 3.15)
-
-* `Compat.Iterators.map` is added. It provides another syntax `Iterators.map(f, iterators...)`
-  for writing `(f(args...) for args in zip(iterators...))`, i.e. a lazy `map`  ([#34352]).
-  (since Compat 3.14)
-
-* `takewhle` and `dropwhile` are added in `Compat.Iterators` ([#33437]). (since Compat 3.14)

-
-* `strides` is defined for Adjoint and Transpose ([#35929]). (since Compat 3.14)
-

 ## Developer tips
 
 One of the most important rules for `Compat.jl` is to avoid breaking user code
