As you probably already seen in a post by Baron, Sphinx Release 0.9.8 is finally out, just in time for OSCON 2008. Even though it is “minor release” if you look at the number, it is major release in practice (and you can view snapshots as minor releases). The changes since 0.9.7 are dramatic with over 70 new features corresponding to over 15 months of work. With zero in front it still looks like “beta” release though it is very stable and widely used.

Myself I would have already named it 1.3.0 or something like it (with 3rd number used for minor releases) and use version 2.0.0 as a target for full live updates. Though it looks like Andrew has set his goal on naming it 1.0 only when dynamic updates work and starting from 0.9.1 it did not allow too much version flexibility.

Sphinx will be presented this year on OSCON as .ORG Exhibitor, with me running the show - it was too expensive for Andrew to come from Russia, especially as he did not get a session at OSCON.

As Baron writes it is not the number of rows returned by the query but number of rows accessed by the query will most likely be defining query performance. Of course not all row accessed are created equal (such as full table scan row accesses may be much faster than random index lookups row accesses in the same table) but this is very valuable data point to optimize query anyway.
