[sheepdog-users] [ANNOUNCE, CAUTION] sheepdog stable release v0.8.2

[Hitoshi Mitake]

Hi sheepdog users,

I released v0.8.2 of stable branch. You can download a source archive
from these URLs:
tar.gz: https://github.com/sheepdog/sheepdog/archive/v0.8.2.tar.gz
zip: https://github.com/sheepdog/sheepdog/archive/v0.8.2.zip

The content of v0.8.2 is same to v0.8.2_rc1.

I have to emphasis on the point that updating from v0.8.0 or v0.8.1 to
v0.8.2 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 of erasure coded
VDI. This update problem was introduced by v0.8.1 but the update
mechanism itself had a bug, so you need to launch sheep with -u for
v0.8.2.

You can update from both of existing v0.8.0 and v0.8.1 cluster to
v0.8.2.

Below is a summary of the commits backported since v0.8.1:
