Bug description:
[Impact]
* An explanation of the effects of the bug on users and
* justification for backporting the fix to the stable release.
* In addition, it is helpful, but not required, to include an
explanation of how the upload fixes this bug.
[Test Case]
* detailed instructions how to reproduce the bug
* these should allow someone who is not familiar with the affected
package to reproduce the bug and verify that the updated package fixes
the problem.
[Regression Potential]
* discussion of how regressions are most likely to manifest as a
result of this change.
* It is assumed that any SRU candidate patch is well-tested before
upload and has a low overall risk of regression, but it's important
to make the effort to think about what ''could'' happen in the
event of a regression.
* This both shows the SRU team that the risks have been considered,
and provides guidance to testers in regression-testing the SRU.
[Other Info]
* Anything else you think is useful to include
* Anticipate questions from users, SRU, +1 maintenance, security teams and
the Technical Board
* and address these questions in advance
--- Original description ---
Please backport libzstd 1.3.1+dfsg-1 (universe) from artful to xenial.
Reason for the backport:
========================
Current version in Xenial is v0.5.1,
it's an experimental version, using its own, incompatible format.
As a consequence, zstd on Ubuntu Xenial is not compatible with the rest of
the world.
This is of important concern for products using libzstd as a shared library :
on Ubuntu Xenial, produced data is different, not compatible with v1+.
This issue has been made more pressing with the integration of zstd in Linux
Kernel,
as userland tools must also be updated to read and generate zstd.
Note : this request was first improperly filled at :

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the
checklist so that backporters can quickly evaluate the state of testing.
Backport available from PPA:
https://launchpad.net/~ginggs/+archive/ubuntu/backports
* xenial:
[X] Package builds without modification (needs debhelper 10)
[X] zstd installs cleanly and runs
[ ] zstd-dbgsym installs cleanly and runs
[ ] libzstd1-dbgsym installs cleanly and runs
[X] libzstd-dev installs cleanly and runs
[X] libzstd1 installs cleanly and runs
