Version 0.8.0 incompatible with Julia 1.8 and version 0.3.0 lacks documentation

[alfa33333]

Version 0.8.0 does not precompile with version 1.8 as it requires @kwdef, but this is not exported until Julia 1.9. Version 0.3.0 compiles, but the documentation for this version does not appear in the documentation page, only for 0.2.0 and 0.8.0.
