Cert bundle is periodically updated with the upstream Mozilla's NSS root cert store. Retracted certs are moved to deprecated list now and an additional config allows to include them in the default bundle. New config is kept default disabled but can be enabled if one would like to ensure 100% compatibility w.r.t. cert bundle across IDF minor or patch releases. In IDF major release the deprecated list shall be reset.
