PostgreSQL 12 release notes missing breaking change in libpq

The following documentation comment has been logged on the website:

Description:

Hi!

In PostgreSQL 12, libpq's parsing of connection string integer parameters
was made more strict, such that invalid values now result in an error rather
than being silently ignored:
https://github.com/postgres/postgres/commit/e7a2217978d9cbb2149bfcb4ef1e45716cfcbefb

This change resulted in runtime errors/crashes for some of our customers
after we upgraded the Heroku stack images to use v12 of the PostgreSQL
client libs.

We had checked the release notes, but it's not currently mentioned:
https://www.postgresql.org/docs/12/release-12.html

Please could it be added?

Many thanks,

Ed
