Subject: exfatprogs-1.0.4 version released
Date: Fri, 31 Jul 2020 16:16:04 +0900

Hi folk,

In this release, The performance of fsck have been much improved and
the new option in mkfs have been added to adjust boundary alignment.

As the result below, The fsck performance is improved close to windows's fsck
and much faster than the one in exfat-utils package.

We measured the performance on Samsung 64GB Pro microSDXC UHS-I Class 10 which
was filled up to 35GB with 9948 directories and 16506 files.

| Implementation       | version           | execution time (seconds) |
|--------------------- |-------------------|--------------------------|
| **exfatprogs fsck**  | 1.0.4             | 11.561                   |
| Windows fsck         | Windows 10 1809   | 11.449                   |
| [exfat-fuse fsck]    | 1.3.0             | 68.977                   |

And we have been preparing to add fsck repair feature in the next version.
Any feedback is welcome!:)

 * fsck.exfat: display sector, cluster, and volume sizes in the human
   readable format.
 * fsck.exfat: reduce the elapsed time using read-ahead.

 * mkfs.exfat: generate pseudo unique serials while creating filesystems.
 * mkfs.exfat: add the "-b" option to align the start offset of FAT and
   data clusters.
 * fsck.exfat: repair zero-byte files which have the NoFatChain attribute.

 * Fix memory leaks on error handling paths.
 * fsck.exfat: fix the bug that cannot access space beyond 2TB.
