TiDB Operator 1.1.6 Release Notes

Release date: October 16, 2020

TiDB Operator version: 1.1.6

Compatibility Changes

• With #3342, the spec.pd.config will be migrated from YAML format to TOML format automatically; however, if the following parameters are configured in the spec.pd.config, the migration cannot be done after upgrading TiDB Operator to v1.1.6. Therefore, please edit the TidbCluster CR to change the value of the parameter from string format to bool format, for example, from "true" to true.
