This release adds the ability to persist GID across sessions. The GID will be saved with --save-session. There are several restrictions how GID is persisted. See the manual for details. For this change, now GID is 64 bits binary data and represented by 16 characters hex string in RPC query. The disk cache feature was added, which may reduce disk activity. The console readout was redesigned. The warning displayed when --file-allocation=falloc is used on MinGW32 build was removed as a bug.
