Store More and Larger Debug Logs
We raised the maximum size of a debug log from 5 MB to 20 MB. With the 20 MB limit, 99.99% of debug logs aren’t truncated. We also raised the limits for debug log storage per org and debug logs that you can generate in a 15-minute window from 250 MB to 1,000 MB.
Where: This change applies to Lightning Experience, Salesforce Classic, and all versions of the Salesforce app in Enterprise, Performance, Unlimited, Developer, and Database.com editions.
