        Release Notes: MG4J is now based on a new type of index which does not use gap compression and which provides unprecedented performance. This parallel release of the standard and of the big version has source and binary code incompatibilities, so its package prefix has been changed to it.unimi.di.*.

                Release Notes: 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.
