+Julia v1.3 Release Notes
+========================
+
+New language features
+---------------------
+
+* Support for Unicode 12.1.0 ([#32002]).
+* Methods can now be added to an abstract type ([#31916]).
+* Support for unicode bold digits and double-struck digits 0 through 9 as valid identifiers ([#32838]).
+* Added the syntax `var"#str#"` for printing and parsing non-standard variable names ([#32408]).
+
+Language changes
+----------------
+
+
+Multi-threading changes
+-----------------------
+
+* New experimental `Threads.@spawn` macro that runs a task on any available thread ([#32600]).
+* All system-level I/O operations (e.g. files and sockets) are now thread-safe.
+  This does not include subtypes of `IO` that are entirely in-memory, such as `IOBuffer`,
+  although it specifically does include `BufferStream`.
+  ([#32309], [#32174], [#31981], [#32421]).
+* The global random number generator (`GLOBAL_RNG`) is now thread-safe (and thread-local) ([#32407]).
+* New `Channel(f::Function, spawn=true)` keyword argument to schedule the created Task on
+  any available thread, matching the behavior of `Threads.@spawn` ([#32872]).
+* Simplified the `Channel` constructor, which is now easier to read and more idiomatic julia.
+  Use of the keyword arguments `csize` and `ctype` is now discouraged ([#30855], [#32818]).
+
+Build system changes
+--------------------
+
+
+New library functions
+---------------------
+
+* `findfirst`, `findlast`, `findnext` and `findprev` now accept a character as first argument
+  to search for that character in a string passed as the second argument ([#31664]).
+* New `findall(pattern, string)` method where `pattern` is a string or regex ([#31834]).
+* `count(pattern, string)` gives the number of things `findall` would match ([#32849]).
+* `istaskfailed` is now documented and exported, like its siblings `istaskdone` and `istaskstarted` ([#32300]).
+* `RefArray` and `RefValue` objects now accept index `CartesianIndex()` in  `getindex` and `setindex!` ([#32653])
+* Added `sincosd(x)` to simultaneously compute the sine and cosine of `x`, where `x` is in degrees ([#30134]).
+* The function `nonmissingtype`, which removes `Missing` from type unions, is now exported ([#31562]).
+
+Standard library changes
+------------------------
+
+* `Pkg` can now download and install binary artifacts through the `Pkg.Artifacts`
+   submodule and supporting functions. ([#32918])
+* When `wait` (or `@sync`, or `fetch`) is called on a failing `Task`, the exception is propagated as a
+  `TaskFailedException` wrapping the task.
+  This makes it possible to see the location of the original failure inside the task (as well as the
+  location of the `wait` call, as before) ([#32814]).
+* `Regex` can now be multiplied (`*`) and exponentiated (`^`), like strings ([#23422]).
+* `Cmd` interpolation (``` `$(x::Cmd) a b c` ``` where) now propagates `x`'s process flags
+  (environment, flags, working directory, etc) if `x` is the first interpolant and errors
+  otherwise ([#24353]).
+* Zero-dimensional arrays are now consistently preserved in the return values of mathematical
+  functions that operate on the array(s) as a whole (and are not explicitly broadcasted across their elements).
+  Previously, the functions  `+`, `-`, `*`, `/`, `conj`, `real` and `imag` returned the unwrapped element
+  when operating over zero-dimensional arrays ([#32122]).
+* `IPAddr` subtypes now behave like scalars when used in broadcasting ([#32133]).
+* `Pair` is now treated as a scalar for broadcasting ([#32209]).
+* `clamp` can now handle missing values ([#31066]).
+* `empty` now accepts a `NamedTuple` ([#32534]).
+* `mod` now accepts a unit range as the second argument to easily perform offset modular arithmetic to ensure the result is inside the range ([#32628]).
+* `nothing` can now be `print`ed, and interpolated into strings etc. as the string `"nothing"`. It is still not permitted to be interpolated into Cmds (i.e. ``echo `$(nothing)` `` will still error without running anything.) ([#32148])
+* When `open` is called with a function, command, and keyword argument (e.g. ```open(`ls`, read=true) do f ...```)
+  it now correctly throws a `ProcessFailedException` like other similar calls ([#32193]).
+* `mktemp` and `mktempdir` now try, by default, to remove temporary paths they create before the process exits ([#32851]).
+* Added argument `keep` to `unescape_string` ([#27125]).
+
+#### Libdl
+
+* `dlopen()` can now be invoked in `do`-block syntax, similar to `open()`.
+
+#### LinearAlgebra
+
+* The BLAS submodule no longer exports `dot`, which conflicts with that in LinearAlgebra ([#31838]).
+* `diagm` and `spdiagm` now accept optional `m,n` initial arguments to specify a size ([#31654]).
+* `Hessenberg` factorizations `H` now support efficient shifted solves `(H+µI) \ b` and determinants, and use a specialized tridiagonal factorization for Hermitian matrices. There is also a new `UpperHessenberg` matrix type ([#31853]).
+* Added keyword argument `alg` to `svd` and `svd!` that allows one to switch between different SVD algorithms ([#31057]).
+* Five-argument `mul!(C, A, B, α, β)` now implements inplace multiplication fused with addition _C = A B α + C β_ ([#23919]).
+
+#### SparseArrays
+
+* `SparseMatrixCSC(m,n,colptr,rowval,nzval)` perform consistency checks for arguments:
+  `colptr` must be properly populated and lengths of `colptr`, `rowval`, and `nzval`
+  must be compatible with `m`, `n`, and `eltype(colptr)`.
+* `sparse(I, J, V, m, n)` verifies lengths of `I`, `J`, `V` are equal and compatible with
+  `eltype(I)` and `m`, `n`.
+
+#### Dates
+
+* `DateTime` and `Time` formatting/parsing now supports 12-hour clocks with AM/PM via `I` and `p` codes, similar to `strftime` ([#32308]).
+* Fixed `repr` such that it displays `Time` as it would be entered in Julia ([#32103]).
+
+#### Statistics
+
+* `mean` now accepts both a function argument and a `dims` keyword ([#31576]).
+
+#### Sockets
+
+* `Sockets.recvfrom` now returns both host and port as an InetAddr ([#32729]).
+* Added `InetAddr` constructor from `AbstractString`, representing IP address, and `Integer`,
+  representing port number ([#31459]).
+
+#### Miscellaneous
+
+* `foldr` and `mapfoldr` now work on any iterator that supports `Iterators.reverse`, not just arrays ([#31781]).
+
+Deprecated or removed
+---------------------
+
+* `@spawn expr` from the `Distributed` standard library should be replaced with `@spawnat :any expr` ([#32600]).
+* `Threads.Mutex` and `Threads.RecursiveSpinLock` have been removed; use `ReentrantLock` (preferred) or
+  `Threads.SpinLock` instead ([#32875]).
+
+External dependencies
+---------------------
+
+Tooling Improvements
+---------------------
+
+* The `ClangSA.jl` static analysis package has been imported, which makes use of
+  the clang static analyzer to validate GC invariants in Julia's C code. The analysis
+  may be run using `make -C src analyzegc`.
