As of four days ago, the latest release is 6.6.1. This is a point release, intended to fix known bugs in the 6.6.0 version without adding any new features. All releases are considered "stable", or they would not be released. Every attempt is made to find and fix problems before release, but bugs do happen. > Kindly let me know your suggestions because we started with installing SOLR > 6.2 but heard that there are many issues and need to be upgraded to 6.3 or > so. If you need a search engine to be up and in production quickly, the recommendation right now is the latest version - 6.6.1. This is the thirteenth release in the 6.x line, and represents over a year of new features and bugfixes since the 6.0.0 release. The 7.0 release is underway right now, and could be announced as soon as later this week. It also might end up delayed. That depends on whether problems are found and if so, what those problems are. If you have a longer timeframe before you need to be online, it would probably be a good idea to plan on testing 7.0 when it is released, and be ready to upgrade your test environment to new 7.x versions as they come out. You could choose to test 6.6.1 and 7.x concurrently, and go with whichever version you can get working correctly. My personal feeling is that a brand new major release (x.0 version) should not be deployed into production without an extensive amount of testing. That applies to ANY software, not just Solr. It's not that I think the 7.0 version is going to be bad software. It's just that it hasn't received any widespread user testing yet, so any major problems are currently unknown. The developers do a lot of testing, but they can only come up with so many test scenarios. Real-world installations tend to be better at sniffing out bugs. Thanks, Shawn
