Julia v1.1.0 Release Notes

New language features

• An exception stack is maintained on each task to make exception handling more robust and enable root cause analysis using catch_stack (#28878).

Language changes

• Parser inputs ending with a comma are now consistently treated as incomplete. Previously they were sometimes parsed as tuples, depending on whitespace ([#28506]).

New library functions

• splitpath(p::String) function, which is the opposite of joinpath(parts...): it splits a filepath into its components (#28156).
• isnothing(::Any) function, to check whether something is a Nothing, returns a Bool ([#29679]).

Standard library changes

• CartesianIndices can now be constructed from two CartesianIndexes I and J with I:J (#29440).
• copy! support for arrays, dicts, and sets has been moved to Base from the Future package ([#29173]).
• Channels now convert inserted values (like containers) instead of requiring types to match ([#29092]).
• range can accept the stop value as a positional argument, e.g. range(1,10,step=2) ([#28708]).
• edit can now be called on a module to edit the file that defines it ([#29636]).

Compiler/Runtime improvements

Deprecated or removed

• one(i::CartesianIndex) should be replaced with oneunit(i::CartesianIndex) (#29442).
