*`public` is a new keyword. Symbols marked with `public` are considered public
7
-
API. Symbols marked with `export` are now also treated as public API. The
8
-
difference between `public` and `export` is that `public` names do not become
9
-
available when `using` a package/module ([#50105]).
10
-
*`ScopedValue` implements dynamic scope with inheritance across tasks ([#50958]).
11
-
* The new macro `Base.Cartesian.@ncallkw` is analogous to `Base.Cartesian.@ncall`,
12
-
but allows to add keyword arguments to the function call ([#51501]).
13
-
* Support for Unicode 15.1 ([#51799]).
14
-
* Three new types around the idea of text with "annotations" (`Pair{Symbol, Any}`
15
-
entries, e.g. `:lang => "en"` or `:face => :magenta`). These annotations
16
-
are preserved across operations (e.g. string concatenation with `*`) when
17
-
possible.
18
-
*`AnnotatedString` is a new `AbstractString` type. It wraps an underlying
19
-
string and allows for annotations to be attached to regions of the string.
20
-
This type is used extensively in the new `StyledStrings` standard library to
21
-
hold styling information.
22
-
*`AnnotatedChar` is a new `AbstractChar` type. It wraps another char and
23
-
holds a list of annotations that apply to it.
24
-
*`AnnotatedIOBuffer` is a new `IO` type that mimics an `IOBuffer`, but has
25
-
specialised `read`/`write` methods for annotated content. This can be
26
-
thought of both as a "string builder" of sorts and also as glue between
27
-
annotated and unannotated content.
28
-
*`Manifest.toml` files can now be renamed in the format `Manifest-v{major}.{minor}.toml`
29
-
to be preferentially picked up by the given julia version. i.e. in the same folder,
30
-
a `Manifest-v1.11.toml` would be used by v1.11 and `Manifest.toml` by every other julia
31
-
version. This makes managing environments for multiple julia versions at the same time
32
-
easier ([#43845]).
33
-
*`@time` now reports a count of any lock conflicts where a `ReentrantLock` had to wait, plus a new macro
34
-
`@lock_conflicts` which returns that count ([#52883]).
35

Language changes
37
8
----------------
38
-
* During precompilation, the `atexit` hooks now run before saving the output file. This
39
-
allows users to safely tear down background state (such as closing Timers and sending
40
-
disconnect notifications to heartbeat tasks) and cleanup other resources when the program
41
-
wants to begin exiting.
42
-
* Code coverage and malloc tracking is no longer generated during the package precompilation stage.
43
-
Further, during these modes pkgimage caches are now used for packages that are not being tracked.
44
-
This means that coverage testing (the default for `julia-actions/julia-runtest`) will by default use
45
-
pkgimage caches for all other packages than the package being tested, likely meaning faster test
46
-
execution. ([#52123])
47
-
48
-
* Specifying a path in `JULIA_DEPOT_PATH` now results in the expansion of empty strings to
49
-
omit the default user depot ([#51448]).
9
+
10
+
- When methods are replaced with exactly equivalent ones, the old method is no
11
+
longer deleted implicitly simultaneously, although the new method does take
12
+
priority and become more specific than the old method. Thus if the new
13
+
method is deleted later, the old method will resume operating. This can be
14
+
useful to mocking frameworks (such as in SparseArrays, Pluto, and Mocking,
15
+
among others), as they do not need to explicitly restore the old method.
16
+
While inference and compilation still must be repeated with this, it also
17
+
may pave the way for inference to be able to intelligently re-use the old
18
+
results, once the new method is deleted. ([#53415])
19
+
20
+
- Macro expansion will no longer eargerly recurse into into `Expr(:toplevel)`
21
+
expressions returned from macros. Instead, macro expansion of `:toplevel`
22
+
expressions will be delayed until evaluation time. This allows a later
23
+
expression within a given `:toplevel` expression to make use of macros
24
+
defined earlier in the same `:toplevel` expression. ([#53515])

Compiler/Runtime improvements
52
27
-----------------------------
53
-
* Updated GC heuristics to count allocated pages instead of individual objects ([#50144]).
54
-
* A new `LazyLibrary` type is exported from `Libdl` for use in building chained lazy library
55
-
loads, primarily to be used within JLLs ([#50074]).
56
-
* Added support for annotating `Base.@assume_effects` on code blocks ([#52400]).
57
-
* The libuv library has been updated from a base of v1.44.2 to v1.48.0 ([#49937]).
28
+
29
+
- Generated LLVM IR now uses actual pointer types instead of passing pointers as integers.
30
+
This affects `llvmcall`: Inline LLVM IR should be updated to use `i8*` or `ptr` instead of
31
+
`i32` or `i64`, and remove unneeded `ptrtoint`/`inttoptr` conversions. For compatibility,
32
+
IR with integer pointers is still supported, but generates a deprecation warning. ([#53687])

Command-line option changes

---------------------------
61
36
62
-
* The entry point for Julia has been standardized to `Main.main(ARGS)`. This must be explicitly opted into using the `@main` macro
63
-
(see the docstring for further details). When opted-in, and julia is invoked to run a script or expression
64
-
(i.e. using `julia script.jl` or `julia -e expr`), julia will subsequently run the `Main.main` function automatically.
65
-
This is intended to unify script and compilation workflows, where code loading may happen
66
-
in the compiler and execution of `Main.main` may happen in the resulting executable. For interactive use, there is no semantic
67
-
difference between defining a `main` function and executing the code directly at the end of the script ([50974]).
68
-
* The `--compiled-modules` and `--pkgimages` flags can now be set to `existing`, which will
69
-
cause Julia to consider loading existing cache files, but not to create new ones ([#50586]
70
-
and [#52573]).
37
+
* The `-m/--module` flag can be passed to run the `main` function inside a package with a set of arguments.
38
+
This `main` function should be declared using `@main` to indicate that it is an entry point.

120
80
#### StyledStrings
121
81
122
-
* A new standard library for handling styling in a more comprehensive and structured way ([#49586]).
123
-
* The new `Faces` struct serves as a container for text styling information
124
-
(think typeface, as well as color and decoration), and comes with a framework
125
-
to provide a convenient, extensible (via `addface!`), and customisable (with a
126
-
user's `Faces.toml` and `loadfaces!`) approach to
127
-
styled content ([#49586]).
128
-
* The new `@styled_str` string macro provides a convenient way of creating a
129
-
`AnnotatedString` with various faces or other attributes applied ([#49586]).
130
-
131
82
#### JuliaSyntaxHighlighting
132
83
133
-
* A new standard library for applying syntax highlighting to Julia code, this
134
-
uses `JuliaSyntax` and `StyledStrings` to implement a `highlight` function
135

84
#### Package Manager
138
85
139
86
#### LinearAlgebra
140
-
*`cbrt(::AbstractMatrix{<:Real})` is now defined and returns real-valued matrix cube roots of real-valued matrices ([#50661]).
141
-
*`eigvals/eigen(A, bunchkaufman(B))` and `eigvals/eigen(A, lu(B))`, which utilize the Bunchkaufman (LDL) and LU decomposition of `B`,
142
-
respectively, now efficiently compute the generalized eigenvalues (`eigen`: and eigenvectors) of `A` and `B`. Note: The second
143
-
argument is the output of `bunchkaufman` or `lu` ([#50471]).
144
-
* There is now a specialized dispatch for `eigvals/eigen(::Hermitian{<:Tridiagonal})` which performs a similarity transformation to create a real symmetrix triagonal matrix, and solve that using the LAPACK routines ([#49546]).
145
-
* Structured matrices now retain either the axes of the parent (for `Symmetric`/`Hermitian`/`AbstractTriangular`/`UpperHessenberg`), or that of the principal diagonal (for banded matrices) ([#52480]).
146
-
*`bunchkaufman` and `bunchkaufman!` now work for any `AbstractFloat`, `Rational` and their complex variants. `bunchkaufman` now supports `Integer` types, by making an internal conversion to `Rational{BigInt}`. Added new function `inertia` that computes the inertia of the diagonal factor given by the `BunchKaufman` factorization object of a real symmetric or Hermitian matrix. For complex symmetric matrices, `inertia` only computes the number of zero eigenvalues of the diagonal factor ([#51487]).
147
-
* Packages that specialize matrix-matrix `mul!` with a method signature of the form `mul!(::AbstractMatrix, ::MyMatrix, ::AbstractMatrix, ::Number, ::Number)` no longer encounter method ambiguities when interacting with `LinearAlgebra`. Previously, ambiguities used to arise when multiplying a `MyMatrix` with a structured matrix type provided by LinearAlgebra, such as `AbstractTriangular`, which used to necessitate additional methods to resolve such ambiguities. Similar sources of ambiguities have also been removed for matrix-vector `mul!` operations ([#52837]).
148
-
*`lu` and `issuccess(::LU)` now accept an `allowsingular` keyword argument. When set to `true`, a valid factorization with rank-deficient U factor will be treated as success instead of throwing an error. Such factorizations are now shown by printing the factors together with a "rank-deficient" note rather than printing a "Failed Factorization" message ([#52957]).

-
* New `@create_log_macro` macro for creating new log macros like `@info`, `@warn` etc. For instance
152
-
`@create_log_macro MyLog 1500 :magenta` will create `@mylog` to be used like `@mylog "hello"` which
