Source: libcoap2 Version: 4.2.1-1 Severity: serious The API version 2 of libcoap was given up long ago and is replaced by API v3. The last version for v2 was released on 2019. Thus no upstream development and no updates will happen for this package and we should not ship libcoap2 packages in bookworm onward.
There is a replacement avaialable - users should switch to libcoap3. https://tracker.debian.org/pkg/libcoap3 Regards Carsten
