Downloads
The suggested downloads are the current version plus the dictionaries. Get those! However, for general amusement and digital archaeologists, we also offer all the previous versions in the Archive section, too.
Sphinx 3.0.1, Dec 2017
The most current version. Battle-tested in prod, developed, supported, etc. Now with full document storage, attribute indexes, JSON key compression, updated index format, and a bunch more improvements.
Sources
Currently only available under a delayed FOSS (or commercial) license for several reasons; going back to regular plain old GPL is planned but timing is moot; so email us if you require the sources immediately.
Archive
Sphinx versions 2.x and before are now all archived; get them from Archive versions page.
