GAP.jl 0.4.0 released

We are pleased to announce the release of GAP.jl 0.4.0, a major update to the GAP.jl package which provides full bidirectional access to the GAP computer algebra system from the Julia language and vice-versa.

Here is an overview of the changes in this release:

• Add GAP.prompt() function which gives a GAP prompt inside Julia
• Add support for Julia keyword arguments on the GAP side
• Overload the Julia ‘in’ operator for GAP objects
• Add conversion constructors for various Julia types, to allow for more idiomatic Julia code accessing GAP objects
• Improve GAP <-> Julia conversions
• Show the GAP banner again by default, unless we are being loaded from Oscar.jl
• Switch to Julia “artifact” system for downloading the GAP sources, which can save time and disk space when rebuilding or reinstalling GAP.jl
• Complete overhaul of the build process for GAP, making it more robust
• Ensure that we link against the same GMP and readline as other components of OSCAR do
• Remove the implicit dependency on the LinearAlgebra standard library
• Fix a bunch of minor bugs
• Various janitorial changes
