GAP.jl 0.7.0 released

Today GAP.jl 0.7.0 has been released.

Diff since v0.6.2

This is the first release of the 0.7.x series. It contains the following breaking changes compared to the 0.6.x release:

• Require Julia 1.6 or later.
• Remove LoadPackageAndExposeGlobals. If you are using this, see https://github.com/oscar-system/GAP.jl/pull/696 for alternatives.
• Remove all convert methods. If you were using convert(GapObj, val), you can use GapObj(val) or julia_to_gap(val) instead. If you were using convert(T,gapobj), use T(gapobj) or julia_to_gap(gapobj) instead.
• Remove GAP.gap_exe(). Instead please use GAP.create_gap_sh(path).
• Remove GAP function IsArgumentForJuliaFunction. No replacement should be necessary.
• Remove GAP function ImportJuliaModuleIntoGAP. As a replacement, use JuliaEvalString("import MODULENAME").
• Restrict GapObj constructor by adding a return type annotation that ensures only values of type GapObj are returned. If you relied on this also returning Int, Bool or FFE, please use the GAP.Obj constructor instead. If you relied on also Julia objects being returned, you should probably revise your code; but if you determine that you still really really have to do this, you can by using julia_to_gap.

Other changes:

• Add GapInt type union
• Patch the GAP package manager to perform downloads via Julia’s Downloads.download to avoid certain failure scenarios
• Add @wrap macro as an alternative to @gapwrap for certain use cases.
• Don’t show the GAP banner if Julia is started with the --quiet flag
• Call the GAP AtExit handler when exiting Julia, so that e.g. the command line history is saved (if the user enabled this in their preferences) or temporary directories are removed.
• Many internal changes and refactoring

Closed issues:

• Override GAP function PKGMAN_DownloadURL to use Julia for downloading? (#692)
• When leaving GAP prompt mode, save the history (if the user requested it) (#719)
