In 8.0.19, the IS_DD_VERSION constant is set to 80020 (8.0.20): 

But it probably should be 80019 (8.0.19)

The root cause seem to be that two unrelated changes both increased it between 8.0.18 and 8.0.19:

https://github.com/mysql/mysql-server/commit/8745f8ccb5fb2aee8c21b43c9b8a6d7456a67a67#diff... (from 80018 -> 80019)
https://github.com/mysql/mysql-server/commit/48526e2da4f3eed8c055467a2311d23068a1b378 (from 80019 to 80020)

Hello Zsolt Parragi,

Thank you for the report and feedback.

Closing as duplicate of bug#97948 (where a check has been implemented to prohibit such updates in the source code). Note that this version number is as such internal, and there are no consequences for users that the IS_DD_VERSION is 8.0.20 .
