There is a strong push to keep the release branch (currently branch_4x) in a state where it can always be used in place of a full release. Breakage does sometimes happen, but it's usually detectable by running the large suite of unit tests that are part of the source code. When something does break, it is typically fixed very quickly. It's development code, and the pace of change in the Lucene/Solr project is VERY fast. The process to release 4.5 is wrapping up as I type this. The release vote passed, so the release candidate will be finalized and start copying to download mirrors. It is likely to be only a few more days before the release announcement is made. You can probably get it before the announcement is made by checking the parent directory on a download mirror. Nothing is set in stone. There's no set schedule for releases. Since the 4.0 release, minor releases are dropping about once every 1-3 months. Two of those minor releases were quickly followed by point releases to fix some bigger bugs. Releases happen when one of the committers decides that it's time and takes the reins to act as release manager. We don't ignore the community, so if there are strong voices wanting a release, it's likely to happen. A 4.6.0 release will probably happen before the end of the year, but I can't guarantee that. The release timeframe for 5.0 is *completely* undecided. It might be a few months from now, it might be a year from now. Some of the things that have been tentatively planned for that release are nowhere near finished. Thanks, Shawn
