Enhancements
More accurate "ping" latency measurements
Cloudprober now uses SO_TIMESTAMP socket option (on non-windows OS) to make latency measurements much more accurate. (#546)
Better isolation in HTTP probes for multiple targets
HTTP probes for multiple targets execute in independent goroutines now. This allows for better isolation between probes.
Add HTTP header validator for HTTP probe
You can now add a header validator to an HTTP probe (example).
