Loaded local plugin can not be displayed in "Plugins" menu for v4.0

Hello teams,
We are working on a custom plugin for XBim Xplorer and it seems that our plugin can be loaded locally by drag and drop the package file into the plugin setting window in the latest development version (5.0), but not the official release version (4.0).
We wonder if there is a different in XBim.Presentation v4.0 and XBim.Presentation v5.0.
Is it possible to build XBim.Presentation v5.0 as well as other component if required for XBim Xplorer v4.0?
When does the official XBim 5.0 will be released?
Best regards.

Hello,
the release of v50 is long overdue.
I've neglected this repo for a while as I had to focus on our internal high performance option, apologies.

You can download v50 from http://www.overarching.it/dload/XbimXplorer5/Setup.exe

I'll try to to move it to our production servers at some point, I hope soonish.
