The branch_5x effort is to release what would have been 4.11 as 5.0. The most notable reason being backcompat for 3x indexes, which as Robert has put it is "unmaintainable".

The intent here is to have the next release of Lucene be 5.0. Robert has put in a great deal of effort in making improvements in a new Lucene50 codec that were simply not possible on 4x. or simply waiting on some major change that actually warrants a 5.0. There are already some major changes in 5.0: nio2, tons more index corruption protection, super improved debugging for memory allocation of index structures, simpler tokenizer/analyzer interface without Reader, ram usage improvements with the 50 codec work so far. I know I have a list of things I'd like to do API-wise. IMO, a few months, maybe more.
