Serial Number
The Serial Number indicates the range of certificates in a bundle. For example, a bundle with 100 certificates will have
a Serial Number from 1 to 100. Previously, the Serial Number was composed of a GSRN and a sequential number with leading
zeros, such as 643002406555908611 + 000000000001. This format will be preserved for the existing certificates and
bundles. However, for any new certificates, the Serial Number will start from 1 and end with N where N is the number of
issued certificates, and as such the numeric ranges won't be globally unique any more by themselves.
