## Community Health:

Since our move to GitHub Issues, we are now getting bug reports that have been
long underreported. This new collaboration channel with end users is helping
us zero in on bugs, and is also helping to drive some PR activity from
contributors.

This quarter has seen a decrease in activity on Lucene.NET due to focus on the
Xamarin.Android tests, which were added to the smaller J2N dependency project
first before we scale up the approach for use in ICU4N and Lucnene.NET.
