[sheepdog-users] [ANNOUNCE, CAUTION] sheepdog stable release v0.8.3_rc1

[Hitoshi Mitake]

Hi sheepdog users and developers,

I released v0.8.3_rc1 of stable branch. You can download a source
archive from these URLs:
tar.gz: https://github.com/sheepdog/sheepdog/archive/v0.8.3_rc1.tar.gz
zip: https://github.com/sheepdog/sheepdog/archive/v0.8.3_rc1.zip

This update contains important bugfixes for the md functionality and
some improvements e.g. better logging.

I have to emphasis on the point that updating from v0.8.x (x < 3) to
v0.8.3_rc1 requires "-u" option, because it contains updating store
format. Sorry for inconvenience but the format update is a necessary
change for clusters which store many objects.

If no one disagrees about this release candidate in 2 days, it will be
v0.8.3 officially.

Below is a summary of commits backported after v0.8.3_rc0:

Bingpeng Zhu (1):
      sheep/cluster: fix error in sheep log

Liu Yuan (1):
      tests/func: fix spurious error for 032

Robin Dong (2):
      sheep/md: add main_fn marker to for_each_object_in_wd()
      sheep/md: called get_vnode_info() only once in for_each_object_in_wd()

Ruoyu (2):
      tests/unit: unit test failed because interfaces were changed.
      sheep: fix sheep sometimes cannot be killed successfully

Thanks,
Hitoshi
