The curl project has updated the Mozilla CA certificate store earlier last week (01/01/2020).

This update coincides with CA certificate list changes to Mozilla NSS 3.48.

The following CA certificate was added:

• Entrust Root Certification Authority - G4 Cert

The curl project specifies that the CA certificate store file was changed on 11/27/2019 with 137 certificates from the previous 137 certificates in October 2019.

A quick check using the diff tool (diff -u cacert-2019-10-16.pem cacert-2019-11-27.pem) generated the following output:

--- cacert-2019-10-16.pem	2019-10-20 09:35:38.271642200 -0400
