v0.5.0

Highlights:

• Backup hooks - users can now specify that custom scripts within their containers should be executed during Pod backups. This is particularly useful for stateful workloads where disk buffers need to be flushed, database commands need to be issued, etc. (#112)
• Multi-AZ cluster support - we now support backups including PV snapshots for clusters spanning multiple AZs. Ark no longer expects an AZ to be specified in the config; the AZ for each PV will be recorded during backup execution and used for subsequent restores. (#102)
• Easier backups of individual namespaces - it's now possible to backup one or more namespaces, including any PVs used by them, without having to explicitly exclude cluster-scoped resources. Simply use: ark backup create <backup-name> --include-namespaces=<ns1,ns2,...>, and Ark will automatically exclude irrelevant cluster-scoped resources. (#65, #128, #147)
• Ark CLI binaries - Going forward, we recommend running the Ark CLI binary directly rather than in a container. We're now publishing these as part of releases. (#148)

Breaking Changes:

• The backup tar file format has changed. Backups created using previous versions of Ark cannot be restored using v0.5.0.
• When backing up one or more specific namespaces, cluster-scoped resources are no longer backed up by default, with the exception of PVs that are used within the target namespace(s). Cluster-scoped resources can still be included by explicitly specifying --include-cluster-resources.

All New Features:

• Add customized user-agent string #69, @jrnt30

• Exclude nodes from restoration #99, @jrnt30
• Add a FAQ #113, @julia-stripe
• Record PV availability zone and use it when restoring #102, @ashish-amarnath
• Back up the PV associated with a PVC #65, @skriss
• Add --include-cluster-resources flag to ark backup create #128, @skriss
• Add --include-cluster-resources flag to ark restore create #147, @skriss
• Properly support resource restore priorities across cluster-scoped and namespace-scoped resources #132, @dgoodwin
• Support ark create ... and ark get ... #81, @ncdc
• Make ark run as cluster-admin #145, @skriss
• Add pod exec backup hooks #112, @ncdc
• Support cross-compilation & upgrade to go 1.9 #148, @ncdc

Bug Fixes:

• Make config change detection more robust #96, @ncdc

Thanks as always to all our contributors!
