Review Comment:
Minor suggestions:
```suggestion
<li>A problem in Connect with <code>error.tolerance</code> was
fixed. Starting in 3.2.0, when
a source connector uses <code>errors.tolerance=all</code> and
Connect's producer fails to
successfully send a source record to the topic, the error is
properly reported and the connector
continues, but Connect stops committing source offsets for that
source connector and a
memory leak will eventually cause the Connect worker to fail
with an OutOfMemoryError.
