Hi Vladimir,
For the release notes of 42.0 you should add the keyword: BUG: setCharacterStream truncates data. The bug is fixed in 42.1.0
additionally add:
BUG: No suitable driver found for jdbc:postgresql when using a DataSource implementation. The bug is fixed in 42.1.0
There where many reports related to the this problem, so it should be highlighted that is fixed now.
Now that there will be an imminent 42.1.0 release, I have to propose a change in the release management of the driver, try to get a "release early, release often" approach and make use of the new versioning. IMO when an bug is introduced and is fixed, is should be released ASAP, for the #768 (DataSource) bug it should be followed by a 42.0.1 release, for the logical replication bug it should follow a 42.0.2 release, since a feature is introduced (REF_CURSOR using getObject) before the fix for #800 (setCharacterStream), then it have to wait to the 42.1.0, that is basically the idea... bugfixes released often, but I'm not sure how to properly balance it with feature release.
