So... what if we change up how we develop and release Lucene: * A major release always bumps the major release number (2.x -> 3.0), and, starts a new branch for all minor (3.1, 3.2, 3.3) releases along that branch * There is no back compat across major releases (index nor APIs), but full back compat within branches. This would match how many other projects work (KS/Lucy, as Marvin describes above; Apache Tomcat; Hibernate; log4J; FreeBSD; etc.). The 'stable' branch (say 3.x now for Lucene) would get bug fixes, and, if any devs have the itch, they could freely back-port improvements from trunk as long as they kept back-compat within the branch. I think in such a future world, we could: * Remove Version entirely! * Not worry at all about back-compat when developing on trunk * Give proper names to new improved classes instead of StandardAnalzyer2, or SmartStandardAnalyzer, that we end up doing today; rename existing classes. * Let analyzers freely, incrementally improve * Use interfaces without fear * Stop spending the truly substantial time (look @ Uwe's awesome back-compat layer for analyzers!) that we now must spend when adding new features, for back-compat * Be more free to introduce very new not-fully-baked features/APIs, marked as experimental, on the expectation that once they are used (in trunk) they will iterate/change/improve vs trying so hard to get things right on the first go for fear of future back compat horrors.
