Changes since version 1.0.32:
* Tarsnap now caches archive metadata blocks in RAM, typically providing
  a 5x - 10x speedup and reduction in bandwidth usage in the "fsck"
  operation and when deleting a large number of archives at once.
* Tarsnap's internal "chunk" metadata structure is now smaller,
  providing a ~10% reduction in usage on 32-bit machines and a ~30%
  reduction in memory usage on 64-bit machines.
* Tarsnap's --newer* options now correctly descend into old directories
  in order to look for new files. (But note that tarsnap's snapshotting
  makes these options unnecessary in most situations.)
* Multiple minor bug fixes and cleanups.
