Any timeline on when Elasticfence 2.3.2 would be released?
What is Elasticfench?
It provides basic HTTP authentication.

You should open an issue in the project itself to ping the authors.
Apparently it has not been released since 2.3.0.
May be you could download the previous version and modify in its zip the plugin descriptor file?
Should work IMO.
