Changes in version 2.56.0                        

Breaking changes

    o   The default value for the `bit64conversion` argument in
	`H5Aread()` and `H5Dread()` has been set explicitly to `"int"`.
	Relying on a missing value or `"default"` results in a warning
	and will be disallowed in the next release cycle.  Users should
	either specify `bit64conversion="int"` explicitly, or omit this
	argument entirely if they wish to use the provided default.

Bug fixes

    o   The value ordering (row-major vs column-major) is not correct
	when reading unsigned integers with `native=TRUE`. Thanks to
	Jared Lumpe for the report and detailed reproducible example:
