 ----------------

+
+  * In string and character literals, backslash `\` may no longer
+    precede unrecognized escape characters ([#22800]).
+
+  * Declaring arguments as `x::ANY` to avoid specialization has been replaced
+    by `@nospecialize x`, which needs to be imported from `Base`. ([#22666]).

     of the socket. Previously the address of the remote endpoint was being
     returned ([#21825]).
 
+  * Using `ARGS` within the ~/.juliarc.jl or within a .jl file loaded with `--load` will no
+    longer contain the script name as the first argument. Instead the script name will be
+    assigned to `PROGRAM_FILE`. ([#22092])
+
+  * The format for a `ClusterManager` specifying the cookie on the command line is now
+    `--worker=<cookie>`. `--worker <cookie>` will not work as it is now an optional argument.
+
+  * The representation of `CartesianRange` has changed to a
+    tuple-of-AbstractUnitRanges; the `start` and `stop` fields are no
+    longer present. Use `first(R)` and `last(R)` to obtain
+    start/stop. ([#20974])
+
 Library improvements
 --------------------
 
+  * The functions `strip`, `lstrip` and `rstrip` now return `SubString` ([#22496]).
+
   * The functions `base` and `digits` digits now accept a negative
     base (like `ndigits` did) ([#21692]).
 
   * The function `randn` now accepts complex arguments (`Complex{T <: AbstractFloat}`)
     ([#21973]).
 
+  * The function `rand` can now pick up random elements from strings, associatives
+    and sets ([#22228], [#21960], [#18155], [#22224]).
+
   * Method lists are now printed as a numbered list. In addition, the source code of a
     method can be opened in an editor by entering the corresponding number in the REPL
     and pressing `^Q` ([#22007]).
@@ -75,9 +100,29 @@ Library improvements
   * `logspace` now accepts a `base` keyword argument to specify the base of the logarithmic
     range. The base defaults to 10 ([#22310]).
 
+  * Added `unique!` which is an inplace version of `unique` ([#20549]).
+
+  * `@test isequal(x, y)` and `@test isapprox(x, y)` now prints an evaluated expression when
+    the test fails ([#22296]).
+
+  * Uses of `Val{c}` in `Base` has been replaced with `Val{c}()`, which is now easily
+    accessible via the `@pure` constructor `Val(c)`. Functions are defined as
+    `f(::Val{c}) = ...` and called by `f(Val(c))`. Notable affected functions include:
+    `ntuple`, `Base.literal_pow`, `sqrtm`, `lufact`, `lufact!`, `qrfact`, `qrfact!`,
+    `cholfact`, `cholfact!`, `_broadcast!`, `reshape`, `cat` and `cat_t`.
+
+  * A new `@macroexpand1` macro for non recursive macro expansion ([#21662]).
+
+  * `Char`s can now be concatenated with `String`s and/or other `Char`s using `*` ([#22532]).
+
 Compiler/Runtime improvements
 -----------------------------
 
+  * The inlining heuristic now models the approximate runtime cost of
+    a method (using some strongly-simplifying assumptions). Functions
+    are inlined unless their estimated runtime cost substantially
+    exceeds the cost of setting up and issuing a subroutine
+    call. ([#22210], [#22732])
 
 Deprecated or removed

     have been deprecated in favor of `isposdef(Hermitian(A, UL))` and `isposdef!(Hermitian(A, UL))`
     respectively ([#22245]).
 
+  * The `bkfact`/`bkfact!` methods that accepted `uplo` and `issymmetric` symbols have been deprecated
+    in favor of using `Hermitian` (or `Symmetric`) views ([#22605]).
+
   * The function `current_module` is deprecated and replaced with `@__MODULE__` ([#22064]).
     This caused the deprecation of some reflection methods (such as `macroexpand` and `isconst`),
     which now require a module argument.
     And it caused the bugfix of other default arguments to use the Main module (including `whos`, `which`).
 
+  * The `Operators` module is deprecated. Instead, import required operators explicitly
+    from `Base`, e.g. `import Base: +, -, *, /` ([#22251]).
+
+  * Bindings to the FFTW library have been removed from Base. The DFT framework for building FFT
+    implementations is now in AbstractFFTs.jl, the bindings to the FFTW library are in FFTW.jl,
+    and the Base signal processing functions which used FFTs are now in DSP.jl ([#21956]).
+
+  * The `corrected` positional argument to `cov` has been deprecated in favor of
+    a keyword argument with the same name (#21709).
+
+  * Omitting a space between the condition and `?` in a ternary expression has been deprecated.
+    Ternaries must now include some amount of whitespace, e.g. `x ? a : b` rather than
+    `x? a : b` ([#22523]).
+
+  * The method `replace(s::AbstractString, pat, r, count)` with `count <= 0` is deprecated
+    in favor of `replace(s::AbstractString, pat, r, typemax(Int))` ([#22325]).
+
+  * `read(io, type, dims)` is deprecated to `read!(io, Array{type}(dims))` ([#21450]).
+
+  * `read(::IO, ::Ref)` is now a method of `read!`, since it mutates its `Ref` argument ([#21592]).
+
+  * `Bidiagonal` constructors now use a `Symbol` (`:U` or `:L`) for the upper/lower
+    argument, instead of a `Bool` or a `Char` ([#22703]).
+
+  * Calling `nfields` on a type to find out how many fields its instances have is deprecated.
+    Use `fieldcount` instead. Use `nfields` only to get the number of fields in a specific object ([#22350]).
+
+  * `fieldnames` now operates only on types. To get the names of fields in an object, use
+    `fieldnames(typeof(x))` ([#22350]).
+
+  * `InexactError` and `DomainError` now take
+    arguments. `InexactError(func::Symbol, type, -3)` now prints as
+    `ERROR: InexactError: func(type, -3)`, and `DomainError(val,
+    [msg])` prints as `ERROR: DomainError with val:\nmsg`. ([#20005],
+    [#22751])
+
+  * The operating system identification functions: `is_linux`, `is_bsd`, `is_apple`, `is_unix`,
+    and `is_windows`, have been deprecated in favor of `Sys.islinux`, `Sys.isbsd`, `Sys.isapple`,
+    `Sys.isunix`, and `Sys.iswindows`, respectively ([#22182]).
+
+  * The forms of `read`, `readstring`, and `eachline` that accepted both a `Cmd` object and an
+    input stream are deprecated. Use e.g. `read(pipeline(stdin, cmd))` instead ([#22762]).
+
+  * The unexported type `AbstractIOBuffer` has been renamed to `GenericIOBuffer` ([#17360] [#22796]).
+
+  * The method `String(io::IOBuffer)` is deprecated to `String(take!(copy(io)))` ([#21438]).
