v5.2.0
CHANGES:
Upgrade the ppx_cstruct
library to use the OCaml 4.11
AST rather than than OCaml 4.04, which in turn should
make it easier to port to ppxlib in the future and
improve interoperability with other PPXs (@bikallem #275).
Also upgrades build files to use dune 2.0 (@bikallem #275)
and fixes the GitHub Actions versions (@smorimoto #273)
and also test OCaml 4.10.0 (@avsm).
