Julia 1.8 has been released with improvements including better support for Apple Silicon, and support for typed globals. Julia is a dynamic language for technical computing that is especially good at running MATLAB and R-style programs. Development began on Julia at MIT in 2009, and has increased in popularity, recently becoming one of the top six languages for machine learning projects on GitHub. . Version 1.6 of Julia added to ability to used typed globals. The team says that non-constant global variables in Julia came with a performance penalty because the compiler cannot reason about their type. This is because they can be reassigned to another object of some other type at runtime. Julia 1.8 adds the option of specifying the type of a non-constant global variable, which blocks the option of reassigning the variable to an object of another type. This change removes much of the cost of using non-constant global variables. Another improvement is support for annotating individual fields of a mutable struct with const annotation. This causes the field to be constant and incapable of being reassigned after creation of the type, meaning the compiler can take advantage of it to improve the generated code. Julia 1.8 also adds the ability to profile code that is already running. The developers say the feature will be useful if you've started some long-running code and progress appears to slow. At any point you can choose to see what's happening without interrupting by triggering a one -second profile. The other major improvement in this release is adoption of Apple Silicon as a Tier 2 supported platform that is covered by Continuous Integration (CI) on dedicated Apple Silicon machines. In the previous release, Julia 1.7 offered an experimental preview of native builds of Julia on Apple Silicon. While this generally worked for basic usage, users experienced frequent segmentation faults because of the way Julia internally uses LLVM to generate and link the code for this platform.Julia 1.8 has moved to a more modern linker, which has better support for ARM CPUs on macOS. Julia 1.8 is available now.
