v0.9

We've officially converted to CMake!
Instructions for building are here: https://mpifileutils.readthedocs.io/en/v0.9/build.html

New Features:

• dcmp: include nanoseconds when comparing timestamps
• dcmp: new --lite option to compare files based on file type, file size, and modification time rather than file content
• drm: new --aggressive option to delete files while walking
• dsync: default behavior no longer deletes files at the destination, deleting now requires new --delete option
• dsync: optionally copies in batches with --batch-files option as form of self-checkpointing long running dsync jobs
• drm: fix segfault when deleting a large number of files
• libmfu: avoid problematic MPI I/O external32 for more consistent file format
• libmfu: support for GPFS ACLs

New Tools:

• dfind: filters file list based on different criteria
• dreln: update symlinks whose targets use absolute paths, useful after dsync
