Julia v1.11 Release Notes
========================
New language features
---------------------
* `public` is a new keyword. Symbols marked with `public` are considered public
API. Symbols marked with `export` are now also treated as public API. The
difference between `public` and `export` is that `public` names do not become
available when `using` a package/module. ([#50105])
* `ScopedValue` implement dynamic scope with inheritance across tasks ([#50958]).
Language changes
----------------
Compiler/Runtime improvements
-----------------------------
* Updated GC heuristics to count allocated pages instead of individual objects ([#50144]).
* A new `LazyLibrary` type is exported from `Libdl` for use in building chained lazy library
loads, primarily to be used within JLLs ([#50074]).
Command-line option changes
---------------------------
* The entry point for Julia has been standardized to `Main.main(ARGS)`. This must be explicitly opted into using the `@main` macro
(see the docstring for further details). When opted-in, and julia is invoked to run a script or expression
(i.e. using `julia script.jl` or `julia -e expr`), julia will subsequently run the `Main.main` function automatically.
This is intended to unify script and compilation workflows, where code loading may happen
in the compiler and execution of `Main.main` may happen in the resulting executable. For interactive use, there is no semantic
difference between defining a `main` function and executing the code directly at the end of the script. ([50974])
Multi-threading changes
-----------------------
Build system changes
--------------------
New library functions
---------------------
* The new `Libc.mkfifo` function wraps the `mkfifo` C function on Unix platforms ([#34587]).
* `hardlink(src, dst)` can be used to create hard links. ([#41639])
* `diskstat(path=pwd())` can be used to return statistics about the disk. ([#42248])
* `copyuntil(out, io, delim)` and `copyline(out, io)` copy data into an `out::IO` stream ([#48273]).
* `eachrsplit(string, pattern)` iterates split substrings right to left.
New library features
--------------------
* `replace(string, pattern...)` now supports an optional `IO` argument to
write the output to a stream rather than returning a string ([#48625]).
Standard library changes
------------------------
#### Package Manager
#### LinearAlgebra
#### Printf
#### Profile
#### Random
* `rand` now supports sampling over `Tuple` types ([#35856], [#50251]).
* `rand` now supports sampling over `Pair` types ([#28705]).
* When seeding RNGs provided by `Random`, negative integer seeds can now be used ([#51416]).
* Seedable random number generators from `Random` can now be seeded by a string, e.g.
`seed!(rng, "a random seed")` ([#51527]).
#### REPL
* Tab complete hints now show in lighter text while typing in the repl. To disable
set `Base.active_repl.options.hint_tab_completes = false` ([#51229])
#### SuiteSparse
#### SparseArrays
#### Test
#### Dates
#### Statistics
* Statistics is now an upgradeable standard library.([#46501])
#### Distributed
* `pmap` now defaults to using a `CachingPool` ([#33892]).
#### Unicode
#### DelimitedFiles
#### InteractiveUtils
Deprecated or removed
---------------------
External dependencies
---------------------
* `tput` is no longer called to check terminal capabilities, it has been replaced with a pure-Julia terminfo parser.
