v0.15.0

BPM

We've made significant progress in moving to BPM (BOSH Process Manager). This is a significant departure from how jobs are launched. Our goal is to standardize on a set of templates, in contrast to the hand-written versions of previous releases. [#161428229], [#161428222]

Bug Fixes

• Bug fix: There was a bug in the Xenial stemcell that prevented proper configuration of ulimit. This was fixed by moving jobs to BPM. [#162247238]
• Bug fix: Fixed issue where MySQL GRA logs were not being purged correctly [#163441056]

Performance Improvements

• Bug fix: There was a performance regression in Percona XtraDB Cluster in the SHOW GLOBAL VARIABLES query, which caused timeouts in proxy health checks. This was fixed by upgrading to Percona XtraDB Cluster v5.7.25-31.35 [#163595933]
• pxc-release uses all available cores during compilation to reduce time to compile [#161100650]

Security Improvements

• There are updates to the add-backup.yml and pxc.yml ops files in mysql-backup-release so that MySQL backups are run as a limited-permissions user, rather than as admin [#157238354]

Improvements to Migrating from cf-mysql-release

• We have better error messaging around improper migrations from cf-mysql-release to pxc-release, such as using incorrect ops-files [#159998828]

Dependency Updates

• pxc-release uses Golang v1.11.x [#160776067]
• pxc-release uses Percona XtraDB Cluster v5.7.25-31.35 [#164316826]
