JSON files in this directory contain browser information, such as their versions. This data is utilized by CBB to select the browsers to test against, and to generate metadata for performance test results, which are then uploaded to Cloud Storage. These JSON files are automatically updated by the CBB new release detector workflow. Please do not update them manually.
You can find the source code for CBB new release detector in the Skia repo. This workflow runs once per day on the Chrome perf Temporal server. Googlers can monitor the workflow on the Temporal dashboard.
