Guider 3.9.9 Release Note

🎉 Guider 3.9.9: First Major Release in 5 Years!

We’re excited to announce Guider 3.9.9, the first major update in half a decade —
and just in time to celebrate Guider's 10th anniversary! 🎂

With over 4,000 commits, Guider now supports 182 powerful commands, making it
a comprehensive performance intelligence service — far beyond a simple monitoring tool.

Guider delivers always-on system monitoring, deep diagnostics, and real-time APIs,
enabling integration with Android apps and servers via TCP/UDS.

🚀 What’s New in 3.9.9

A total of 83 new commands have been added, bringing significant capabilities:

• ✅ Advanced Android tracing support:
  bionic, simpleperf, perfetto, atrace, binder, dumpsys, and more
• 🔥 Visual error analysis for kernel panic, ANR, and app crashes
  using Flame Graphs
• 🧾 Log tracing enhancements:
  kernel, logcat, syslog, DLT, journal
• ⚡ 30+ breakpoint-based command handlers and performance optimization
• 🐛 Robust bug reporting:
  auto-collects logs, video, screenshots, tcpdump, memory, properties, etc.
• 🕒 Boot performance visualization via systemd unit analysis
• 🐍 Python tracing support expanded to cover 2.x through 3.13
• 🔍 Real-time monitoring of file access, system property, ftrace, D-Bus, binder
• 🧠 User-level duplicate memory detection
• 📦 Cgroup-based resource control and throttling
• 🖥️ Improved command output formatting and UX
• 🔧 Overall performance and utility improvements

🌐 Platform-Level Performance Intelligence

Guider has been deployed to millions of production devices, providing
always-on monitoring, automated issue detection, and reporting services.

Using data aggregated from large-scale deployments, Guider enables
system-wide visualization through:

• Flame Graphs
• Histograms
• Violin Plots

These make it easier to identify regressions, resource changes, and
performance bottlenecks at scale.

📡 Built-in API for App & Service Integration

Guider now exposes a command-based API over TCP and UDS, supporting:

• Real-time RPC command execution
• Streaming result data
• Access control for secure client usage

This allows apps and agents to use Guider seamlessly, enabling real-time
visualization or forwarding of performance data.
