      • Adjusted default displayed metrics and added bar charts to show relative sizes of metrics
    • Added service topology
      • Support for defining integrated business access topology for cloud and on-premises
  • Applications
    • Distributed Tracing
      • Adjusting the split ratio of the right-slide page does not scale the flame graph
      • Support for tracing starting from network Span
      • Flame graph supports displaying network Span's collection NIC information
      • Left quick filter box supports quick filtering and switching of signal sources
    • Continuous Profiling
      • Support for linked display of tables and flame graphs
      • Optimized merging logic of Function Stack in flame graph
      • Compressed storage of Function Stack in ClickHouse
      • Support for eBPF collection of On-CPU Profile data for compiled (Golang/Rust, etc.) and interpreted (Java, etc.) languages
  • Infrastructure
    • Added host and container pages, displayed based on Prometheus metrics
  • Events
    • Split the events page into three pages: resource changes, file read/write, and alert practices
  • GUI
    • Enhanced snapshot search capabilities: support for sorting, condition copying, etc.
    • Search bar supports pasting Key: value search conditions
    • Search bar supports modifying operators of existing conditions
    • Simplified page search conditions and conditions carried by the right-slide page to improve usability
    • Comprehensive UI optimization of the page

    • Support for continuously opening multiple right-slide pages and jumping between different right-slide pages
    • Event data displayed in the right-slide page can be switched to view client-side or server-side events separately
    • Popup page for viewing database fields supports displaying table names
    • Support for viewing search conditions of the current Panel

#2. Dashboard, Metrics, Alerts, Reports

  • Dashboard
    • Support for dragging to modify table size
    • Optimized display details of bar charts
    • Added new Panel type: overview map
    • Refactored Panel editing page

  • GUI
    • Unified search condition input boxes for Panel editing page, metrics search page, and alert policy editing page

#3. Resources, System

  • Resources
    • Optimized display of POD list, VPC list, availability zone list, and region list, added container node count and collector status columns
    • Support for synchronizing CloneSet and Advanced StatefulSet workloads in OpenKruise
    • Support for independently configuring synchronization intervals for different cloud platforms
    • Support for synchronizing IP addresses on loopback interfaces (usually VIPs)
  • Integration
    • Prometheus Integration
      • PromQL supports topk and bottomk functions
      • PromQL API supports RFC3339 time format
      • Support for obtaining HTTP Headers in RemoteWrite as additional Labels
      • Optimized storage performance of RemoteWrite, and query performance of RemoteRead and PromQL
    • OpenTelemetry Integration
      • Support for running without ClickHouse
  • Agent
    • Plugin
      • Added support for so plugins, providing C SDK
      • Wasm Demo: Parse error codes in HTTP Payload and reassign response_code and response_exception
