- Document the change at docs/CHANGELOG.md - Copy changes from docs/Single-server-VictoriaMetrics.md to README.md - Add missing handler for processing multitenant requests ( https://docs.victoriametrics.com/vmagent/#multitenancy ) - Substitute github.com/stretchr/testify dependency with 3 lines of code in the added tests - Comment unclear code at lib/protoparser/datadogsketches/parser.go , so @AndrewChubatiuk could update it and add permalinks to the original source code there. - Various code cleanups Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5584 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3091
