Vitess 11.0.1

Known Issues

• A critical vulnerability CVE-2021-44228 in the Apache Log4j logging library was disclosed on Dec 9 2021.
  The project provided release 2.15.0 with a patch that mitigates the impact of this CVE. It was quickly found that the initial patch was insufficient, and additional CVEs
  CVE-2021-45046 and CVE-2021-44832 followed.
  These have been fixed in release 2.17.1. This release of Vitess, v11.0.1, uses a version of Log4j below 2.17.1, for this reason, we encourage you to use version v11.0.4 instead, to benefit from the vulnerability patches.

• An issue where the value of the -force flag is used instead of -keep_data flag's value in v2 vreplication workflows (#9174) is known to be present in this release. A workaround is available in the description of issue #9174.
