Julia v1.1 Release Notes
2+
========================
3+
4+
New language features
5+
---------------------
6+
7+
* An *exception stack* is maintained on each task to make exception handling
8+
more robust and enable root cause analysis. The stack may be accessed using
9+
the experimental function `Base.catch_stack` ([#28878]).
10+
* The experimental macro `Base.@locals` returns a dictionary of current local variable names
11+
and values ([#29733]).
12+
* Binary `~` can now be dotted, as in `x .~ y` ([#30341]).
13+
14+
Language changes
15+
----------------
16+
17+
* Parser inputs ending with a comma are now consistently treated as incomplete.
18+
Previously they were sometimes parsed as tuples, depending on whitespace ([#28506]).
19+
* Spaces were accidentally allowed in broadcast call syntax, e.g. `f. (x)`. They are now
20+
disallowed, consistent with normal function call syntax ([#29781]).
21+
* Big integer literals and command syntax (backticks) are now parsed with the name of
22+
the macro (`@int128_str`, `@uint128_str`, `@big_str`, `@cmd`) qualified to refer
23+
to the `Core` module ([#29968]).
24+
* Using the same name for both a local variable and a static parameter is now an error instead
25+
of a warning ([#29429]).
26+
* `findall(in(b), a)` now returns a `CartesianIndex` when `a` is a matrix or a higher-dimensional array,
27+
for consistency with other `findall` methods. Use `LinearIndices(a)[findall(in(b), a)]` to get
28+
the old behavior, or `CartesianIndices(a)[findall(in(b), a)]` to get the new behavior
29+
on previous Julia versions ([#30226]).
30+
* `findmin(::BitArray)` and `findmax(::BitArray)` now return a `CartesianIndex` when `a` is a matrix
31+
or a higher-dimensional array, for consistency with other array types.
32+
Use `LinearIndices(a)[findmin(a)[2]]` to get the old behavior, or `CartesianIndices(a)[findmin(a)[2]]`
33+
to get the new behavior on previous Julia versions ([#30102]).
34+
* Method signatures such as
35+
`f(::Type{T}, ::T) where {T <: X}` and
36+
`f(::Type{X}, ::Any)`
37+
are now considered ambiguous. Previously a bug caused the first one to be considered more specific in
38+
some cases ([#30160]).
39+
40+
Command-line option changes
41+
---------------------------
42+
43+
* When a script run in interactive mode (`-i`) throws an error, the REPL now starts after
44+
the error is displayed. Previously the REPL only started if the script completed without
45+
error ([#21233]).
46+
47+
New library functions
48+
---------------------
49+
50+
* `splitpath(p::String)` function, which is the opposite of `joinpath(parts...)`: it splits a filepath
51+
into its components ([#28156]).
52+
* `isnothing(::Any)` predicate, to check whether the argument is `nothing`. ([#29679]).
53+
* `getpid(::Process)` method ([#24064]).
54+
* `eachrow`, `eachcol` and `eachslice` functions provide efficient iterators over slices of arrays ([#29749]).
55+
* `fieldtypes(T::Type)` which returns the declared types of the field in type T ([#29600]).
56+
* `uuid5` has been added to the `UUIDs` standard library ([#28761]).
57+
* Predicates `Sys.isfreebsd`, `Sys.isopenbsd`, `Sys.isnetbsd`, and `Sys.isdragonfly` for
58+
detecting BSD systems have been added ([#30249]).
59+
* Internal `Base.disable_library_threading` that sets libraries to use one thread.
60+
It executes function hooks that have been registered with
61+
`Base.at_disable_library_threading` ([#30004]).
62+
63+
Standard library changes
64+
------------------------
65+
66+
* `CartesianIndices` can now be constructed from two `CartesianIndex`es `I` and `J` with `I:J` ([#29440]).
67+
* `CartesianIndices` support broadcasting arithmetic (+ and -) with a `CartesianIndex` ([#29890]).
68+
* `copy!` support for arrays, dicts, and sets has been moved to Base from the Future package ([#29173]).
69+
* Channels now convert inserted values (like containers) instead of requiring types to match ([#29092]).
70+
* `range` can accept the stop value as a positional argument, e.g. `range(1,10,step=2)` ([#28708]).
71+
* `diff` now supports arrays of arbitrary dimensionality and can operate over any dimension ([#29827]).
72+
* The constructor `BigFloat(::BigFloat)` now respects the global precision setting and always
73+
returns a `BigFloat` with precision equal to `precision(BigFloat)` ([#29127]). The optional
74+
`precision` argument to override the global setting is now a keyword instead of positional
75+
argument ([#29157]).
76+
* The use of scientific notation when printing `BigFloat` values is now consistent with other floating point
77+
types ([#29211]).
78+
* `Regex` now behaves like a scalar when used in broadcasting ([#29913]).
79+
* `Char` now behaves like a read-only 0-dimensional array ([#29819]).
80+
* `parse` now allows strings representing integer 0 and 1 for type `Bool` ([#29980]).
81+
* `Base.tail` now works on named tuples ([#29595]).
82+
* The process id is appended to malloc log files in order to track memory allocations of
83+
multiple processes ([#29969]).
84+
* `Base.julia_cmd` now propagates the `--inline=(yes|no)` flag ([#29858]).
85+
* `Base.@kwdef` can now be used for parametric structs, and for structs with supertypes ([#29316]).
86+
* `merge(::NamedTuple, ::NamedTuple...)` can now be used with more than 2 `NamedTuple`s ([#29259]).
87+
* New `ncodeunits(c::Char)` method as a fast equivalent to `ncodeunits(string(c))` ([#29153]).
88+
* New `sort!(::AbstractArray; dims)` method that can sort the array along the `dims` dimension ([#28902]).
89+
* `range` now accepts `stop` as a positional argument ([#28708]).
90+
* `get(A::AbstractArray, (), default)` now returns `A[]` instead of an empty array ([#30270]).
91+
* `parse(Bool, str)` is now supported ([#29997]).
92+
* `copyto!(::AbstractMatrix, ::UniformScaling)` now supports rectangular matrices ([#28790]).
93+
* `current_project()` now searches the parent directories of a Git repository for a `Project.toml` file.
94+
This also affects the behavior of the `--project` command line option when using the default
95+
`--project=@.` ([#29108]).
96+
* The `spawn` API is now more flexible and supports taking IOBuffer directly as an I/O stream,
97+
converting to a system pipe as needed ([#30278]).
98+
99+
#### Dates
100+
* New `DateTime(::Date, ::Time)` constructor ([#29754]).
101+
* `TimeZone` now behaves like a scalar when used in broadcasting ([#30159]).
102+
103+
#### InteractiveUtils
104+
* `edit` can now be called on a module to edit the file that defines it ([#29636]).
105+
* All compiler-reflection tools (i.e. the `code_` class of functions and macros) now print accurate
106+
line number and inlining information in a common style, and take an optional parameter (debuginfo=:default)
107+
to control the verbosity of the metadata shown ([#29893]).
108+
109+
#### LinearAlgebra
110+
* `isdiag` and `isposdef` for `Diagonal` and `UniformScaling` ([#29638]).
111+
* `mul!`, `rmul!` and `lmul!` methods for `UniformScaling` ([#29506]).
112+
* `Symmetric` and `Hermitian` matrices now preserve the wrapper when scaled with a number ([#29469]).
113+
* Exponentiation operator `^` now supports raising an `Irrational` to an `AbstractMatrix` power ([#29782]).
114+
* Added keyword arguments `rtol`, `atol` to `rank` ([#29926]).
115+
116+
#### Random
117+
* `randperm` and `randcycle` now use the type of their argument to determine the element type of
118+
the returned array ([#29670]).
119+
* A new method `rand(::Tuple)` implements sampling from the values of a tuple ([#25278]).
120+
* `serialize` and `deserialize` now accept a filename argument, like `write` and `read` ([#30151]).
121+
122+
#### SparseArrays
123+
* `sprandn` now supports specifying the output element type ([#30083]).
124+
125+
#### Statistics
126+
* `mean` and `var` now handle more kinds of empty inputs ([#29033]).
127+
128+
External dependencies
129+
---------------------
130+
131+
* 7zip (bundled with Julia on Windows) has been upgraded from version 16.04 to 18.05 ([#30035]).
132+
* Busybox is no longer bundled with Julia on Windows ([#30022]).
133+
* OpenBLAS has been upgraded from 0.3.2 to 0.3.3 ([#29845]).
134+
* The source code for Pkg is no longer included in JuliaLang/julia. Pkg is instead
135+
downloaded during the build process ([#29615]).
136+
* LLVM has been upgraded to 6.0.1 and support for LLVM < 6.0 has been dropped ([#28745], [#28696]).
137+
* Pkg has been upgraded to version 1.1 ([#30342]).
138+
139+
Deprecated or removed
140+
---------------------
141+
142+
* `one(i::CartesianIndex)` should be replaced with `oneunit(i::CartesianIndex)` ([#29442]).
143+
* The internal array `Base.Grisu.DIGITS` is deprecated; new code should use `Base.Grisu.getbuf()`
144+
to get an appropriate task-local buffer and pass it to `grisu()` instead ([#29907]).
145+
* The internal function `Base._default_type(T)` has been removed. Calls to it should be
146+
replaced with just the argument `T` ([#29739]).
147+
* `peakflops` has been scheduled to move from `InteractiveUtils` to `LinearAlgebra`
148+
but is already now available as `LinearAlgebra.peakflops` ([#29978]).
