This is part of a parallel release of fastutil, the DSI Utilities, Sux4J, MG4J, WebGraph, etc. that prepares the way for "big" versions supporting more than 2^31 entries in arrays (simulated), elements in lists, terms, documents, nodes, etc. There were several refinements to semantics, and a few subtle, longstanding bugs were fixed.
As principais melhorias foram feitas para a indexação. Leve comprimido construção coleção foi adicionado. Um sistema de pular com quanta variável foi adicionada. Mapeamento de memória é utilizada para índices grandes. Muitos erros foram corrigidos.
