We did: - 5.0 to drop support for 3.x indices, - 6.0 to introduce points and require Java 8+, - 7.0 to introduce doc-value iterators and change how norms are encoded, - 8.0 for impacts / block-max WAND, which required breaking changes on the Similarity API. It would have been challenging to expose these changes with fewer major releases without significantly delaying some very appealing features, which has downsides too. -- Adrien
