The runtime log limits for Vercel Functions have been increased, allowing for significantly larger log entries. These updates replace the previous 4KB-per-line restriction, and they are now live for all projects.
The runtime log limits are now:
Log line size: Up to 256KB per log line.
Log line count: Up to 256 individual log lines per request.
Total log size per request: Up to 1MB (sum of all log lines in a single request).
