Update changelog for 1.2.0-1 release

zfs-auto-snapshot Debian release 1.2.1-1

Debian release 1.1.0-0ubuntu1

Merge pull request zfsonlinux#18 from hawkowl/master

Set zfs-auto-snapshot to use UTC time for snapshots

Debian release 1.0.8-0ubuntu2

Fix pool exclusions.

Use $ZPOOL_STATUS instead of $ZFS_STATUS for pool exclusions.

A mistaken variable name made the pool exclusion logic a no-op and
broke the --skip-scrub switch.

Also correct a trivial comment typo.

Debian release 1.0.8-0ubuntu1

Merge pull request zfsonlinux#2 from ulope/master

Fixed --prefix and --sep regexes

Debian release 1.0.7-0ubuntu1

Fix the hourly-daily transposition in the Makefile.

The hourly cron job was installed to cron.daily, and the daily cron
job was installed to cron.hourly, which caused incorrect scheduling.
