comparisonReportVersion top-level constant
int
const comparisonReportVersion
The format index.json is written in.
Bumped only when a reader of the previous version would get something wrong. Added fields do not bump it — an older reader ignoring a new key is the behaviour that makes adding one cheap, and every field below was added to a file that shipped without it.
Implementation
const comparisonReportVersion = 1;
