- LP1380697: wsrep_sst_xtrabackup-v2 doesn't stop when mysql is SIGKILLed. (full fix for this (as engineeered by Percona) requires Linux-specific patch that we don't carry, but keep xtrabackup scripts as close as possible)

- LP1405668: Race condition between donor and joiner in PXB SST. (fixed)
- LP1405985: Fail early if xtrabackup_checkkpoints is missing. (fixed)
