Sorry for that it seems many code changes, which are caused by and Shift-tab (indentation fix) to line up with the rest of the code. The first code addition is actually only line 222-225, rest is the shift-tab in the line 204-233 section.

Please update with Dev. There seems to be something strange going on in the Changelog.....I am missing the previous version in there.

Needs some corrections in the changelog.

@ykuijs Should be fixed now, I opened the PR just before the last release, I think.
