   > Anyone knows which Java version the latest Lucene.Net maps to?
   
   Lucene 4.8.0 supports Java 4, 5, and 6.
   
   > And why Lucene.Net has no stable version released for such a long time?
   
   Quite simply, because there haven't been enough people contributing, and we only recently
got any sponsorship. There has been 5000+ hours contributed since 2014 on Lucene.NET 4.8.0,
of which I have personally contributed about 4000 hours. Lucene.NET was pretty much ported
in 2017, but we are now trying to finish up all of the dependencies that didn't exist in .NET
(namely [ICU4N](https://github.com/NightOwl888/ICU4N) and [J2N](https://github.com/NightOwl888/J2N)),
testing on different platforms and operating systems, and implement enough of the features
of the test framework that we can be reasonably sure that we aren't getting false positives.
There is also some research to do to work out how to implement some of the features properly
on the .NET platform, quite a bit of cleanup work of the APIs, and more performance tuning
to do. Not to mention chasing down bug reports and answering user inquiries that we could
use help with.
   
   There are around 1100-1200 hours of work left to complete Lucene.NET 4.8.0 to production
with its dependencies. Microsoft has recently sponsored 200 hours, and is considering more
funding. We are also getting some funding from iTextSharp. But, for a project of this size
and complexity we are going to need more contributions, more funding, or both to see this
through to the point it is enterprise-ready.
   
   For anyone interested in sponsoring the project, either do so through our personal GitHub
sponsors accounts or contact me via the email address on my profile and I will provide details
on how to sponsor the project as a whole. Or, if you would like to make a contribution, do
note that anything marked `up-for-grabs` is free for anyone to start working on - simply leave
a message on the issue and we will assign it to you.
