## v1.0.1 2024-05-20

* Prefix all modules (backend / parse_argv) with Mirage_bootvar to avoid
  potential conflicts (#2 @hannesm) -- observed while building
  qubes-mirage-firewall which also depends on mirage-net-xen which provides
  a module named Backend.

## v1.0.0 2024-05-16

* parse-argv, mirage-bootvar-unix, mirage-bootvar-solo5, and mirage-bootvar-xen
  have been merged into the single mirage-bootvar package. This uses dune
  variants to select the concrete implementation. The selection is done by
  the mirage tool which inspects the "target" option in `mirage configure`
  and outputs the desired ocamlfind sublibrary into the dune.build file.
* The main logic is provided by the Mirage_bootvar module, while the
  implementation to retrieve the boot parameters is provided by the dune variant
  backend, and implemented by mirage-bootvar.unix, mirage-bootvar.solo5, and
  mirage-bootvar.xen #1
