#1. v7.0.9 [2025/06/11]

#1.1 Stable Feature

  • AutoTracing
    • Support collecting Unix Socket call logs (l7_flow_log), and enable automatic tracing between TCP/UDP Socket call logs and Unix Socket call logs.
    • Support parsing SRV type DNS call logs, Documentation (opens new window).
    • Optimize parsing of unary type gRPC calls, Documentation.
  • AutoTagging
    • Support collecting change events of K8s resource definitions and ConfigMaps.
  • Server
    • Support MCP Server.
  • Agent
    • When the Agent reaches the traffic rate limit, support choosing between drop or wait strategies. The default behavior is drop, but it can be configured to wait to improve data sending success rate, Documentation.
    • Added a circuit breaker mechanism for free disk space in the Agent runtime environment, Documentation.
    • Support disabling Agent's use of Swap memory, Documentation.
    • Adapt to K8s CNI with identical virtual NIC MAC addresses on the same host.
    • Optimization: Reduce the work done by the Agent when it is disabled.

#2. v7.0.8 [2025/05/16]

#2.1 Stable Feature

  • AutoTracing
    • Support parsing truncated MySQL protocol content.
  • Agent
    • Support compressing and sending call logs and flow logs. In test environments, call log compression ratio can reach 8:1, Documentation.

#3. v7.0.7 [2025/04/28]

#3.1 Stable Feature

  • AutoTracing
    • Enrich eBPF hook points for collecting file read/write events (io_event) to improve adaptability.
  • AutoTagging
    • Optimize the meaning of the process_kname field in call logs and file read/write event data, changing from kernel thread name to system process name for better readability.
    • Aggregate processes with the same cmdline within the same cloud host or the same K8s workload into a unique gprocess to reduce redundant process information.
    • Optimize default values of the process matcher, Documentation.
      • By default, ignore collection of process information for sleep/sh/bash/pause/runc.
      • By default, collect process information and OnCPU profiling data for Java/Python, and automatically record the gprocess name as the jar/py file name to avoid all being displayed as java/python.
      • By default, collect process information and OnCPU profiling data for deepflow-*.
      • By default, collect process information inside containers.
    • Optimize the meaning of the response_status field in call logs (l7_flow_log).
      • Normal: Response code is normal.
      • Client Error: Response code indicates a client-side error, e.g., HTTP 4XX.
      • Server Error: Response code indicates a server-side error, e.g., HTTP 5XX.
      • Timeout: If no response is collected within a certain time, the request will be marked as timed out.
        • Agent Application session merge timeout configuration: DNS and TLS default 15s, other protocols default 120s, Documentation.
      • Unknown: When concurrent requests exceed the collector's cache capacity, the oldest requests will be marked as unknown.
        • Agent Maximum session aggregation entries configuration: Default cache of 64K requests, Documentation.
      • Parse Failed: Response was collected but could not parse the response code due to truncation or compression.
        • Agent Payload truncation configuration: By default, parse the first 1024 bytes of the Payload, Documentation.
  • Agent
    • Optimize memory usage of the cache for application performance metrics in the Agent by promptly clearing expired LRU entries, reducing overall memory consumption by 43% in test environments.
    • Aggregate and store flow logs (l4_flow_log) generated by LB health checks, reducing flow log storage overhead by nearly 50% in some production environments, Documentation.
    • Optimize the resource overhead protection mechanism when application protocol recognition fails to avoid mistakenly disabling application protocol parsing, Documentation.

#4. v7.0.6 [2025/04/15]

#4.1 Stable Feature

  • AutoTracing
    • Support parsing compressed MySQL calls, Documentation.
    • Support parsing MySQL Login Response statements.
    • Support parsing multiple DNS requests in TCP Payload.
  • Agent
    • Improve the merge success rate of call logs on the agent side, significantly reducing the proportion of call logs with response_status = Unknown. In test environments, a 50% reduction in unknown proportion is observed.
    • Limit the bandwidth consumption of data sent by the agent, with a default allowance of 100Mbps, Documentation.

#5. v7.0.5 [2025/04/02]

#5.1 Stable Feature

  • AutoTracing
    • Support collection and tracing of RocketMQ protocol, Documentation.
    • Support collection and tracing of Ping protocol, Documentation.
    • Support collection and tracing of Dubbo protocol when using Fastjson serialization, Documentation.

#6. v7.0.4 [2025/03/18]

#6.1 Stable Feature

#7. v7.0.3 [2025/03/05]

N/A

#8. v7.0.2 [2025/02/11]

#8.1 Stable Feature

  • AutoMetrics
    • Add timeout ratio metric (timeout_ratio) to application performance metrics (application, application_map).
  • Server
    • Support terminating remote upgrades of collectors and optimize CPU resource usage of the Server during upgrades.
  • Agent
    • Support limiting the number of sockets used by deepflow-agent, Documentation.

#9. v7.0.1 [2025/01/16]

#9.1 Stable Feature

  • AutoTracing
    • For non-TCP traffic in network flow logs (l4_flow_log), change the end status (close_type) from timeout to normal end (1).

#10. v7.0.0 [2025/01/02]

#10.1 Stable Feature

  • AutoTracing
