# Changelog
`hslua-objectorientation` uses [PVP Versioning][1].
## hslua-objectorientation 2.0.1
Release 2021-11-04.
- Excludes absent properties from `pairs`: Properties that are
optional and not present in a sum-type value are no longer
included in the iterator output produced by `pairs` (i.e., the
`__pairs` metamethod). Previously, the names of absent
properties were pushed with a `nil` value.
## hslua-objectorientation 2.0.0
Release 2021-10-21.
- Published without warning.
