-#### <a id="vitess-lite"/>MySQL binaries in the `vitess/lite` Docker images
-
-In `v19.0.0` we had deprecated the `mysqld` binary in the `vitess/lite` Docker image.
-Making MySQL/Percona version specific image tags also deprecated.
-
-Starting in `v20.0.0` we no longer build the MySQL/Percona version specific image tags.
-Moreover, the `mysqld` binary is no longer present on the `vitess/lite` image.
-
-Here are the images we will no longer build and push:
-
-| Image                           | Available | 
-|---------------------------------|-----------|
-| `vitess/lite:v20.0.0`           | YES       |
-| `vitess/lite:v20.0.0-mysql57`   | NO        |
-| `vitess/lite:v20.0.0-mysql80`   | NO        |
-| `vitess/lite:v20.0.0-percona57` | NO        |
-| `vitess/lite:v20.0.0-percona80` | NO        |
-
-
-If you have not done it yet, you can use an official MySQL Docker image for your `mysqld` container now such as: `mysql:8.0.30`.
-Below is an example of a kubernetes yaml file before and after upgrading to an official MySQL image:
-
-```yaml
-# before:
-
-# you are still on v19 and are looking to upgrade to v20
-# the image used here includes MySQL 8.0.30 and its binaries
-
-    mysqld:
-      mysql80Compatible: vitess/lite:v19.0.0-mysql80
-```
-```yaml
-# after:
-
-# if we still want to use MySQL 8.0.30, we now have to use the
-# official MySQL image with the 8.0.30 tag as shown below 
-
-    mysqld:
-      mysql80Compatible: mysql:8.0.30 # or even mysql:8.0.34 for instance
-```
-
 #### <a id="base-k8s-images"/>`vitess/base` and `vitess/k8s` Docker images
 
 Since we have deleted MySQL from our `vitess/lite` image, we are removing the `vitess/base` and `vitess/k8s` images.
