Michael, Thank you for your inquiry.
Lucene.NET is open source and all of its contributors are volunteers that work on their own schedule, so it is difficult to give you an exact timeframe that it will be released in. However, we have recently been keeping an updated list of remaining tasks and time estimates, which indicate we are roughly 700-800 hours away from completion, with about 1/3 of that time being the completion of the ICU4N project (https://github.com/NightOwl888/ICU4N) (our biggest dependency). So far, there have been roughly 4600 hours contributed toward the release, so we are almost there. The remaining tasks today are roughly 60% of what we had in August 2019. All of the high priority items have been put into JIRA (https://issues.apache.org/jira/browse/LUCENENET) and on GitHub issues in the case of ICU4N (https://github.com/NightOwl888/ICU4N/issues?q=is%3Aopen+is%3Aissue+milestone%3Abeta). Anything marked up-for-grabs is something that anyone can start to work on if they wish to contribute. Let me know if you need any suggestions for small tasks that can be done in a small amount of time to get familiar with the project and the Apache process. At our current rate it may be well into next year (2021) for a stable release, but we could shorten that timeframe significantly (6 months or less) if more people were willing to help out with getting the remaining tasks done. After the stable release of Lucene.NET 4.8.0, we also have a plan to upgrade from Lucene 4.8.0 to Lucene 8.x in around 1700 hours by only porting over the changes (delta) between the releases. But the bottom line is, we need more contributions to get over the finish line in a reasonable timeframe. If you could contribute some of your time, it would mean a lot to the thousands of users that depend on Lucene.NET.

One of the silver linings, if I can use that term lightly for such a serious situation, in the whole affair is the opportunity it offers to switch from urgent commercial work to projects on the back burner. One of my side projects requires a search engine implementation and I had briefly looked at Lucene.Net a while back. Now I see the latest stable release (3.0.3) is from 2012 and 4.8 is in beta. I see that significant work has already been completed and am confident I can get my idea to POC stage - are you close to a final release? I wasn't able to find any indicative dates. Thanks for any help - I realise your priorities may be in other areas at this time. Thanks Michael Ps. Apologies, I have resent this as I hadn't added a new more relevant subject line.
