We recently announced the release of OpenResty XRay 26.5.11. This update brings a host of significant improvements and fixes.

Core Highlights for OpenResty XRay 26.5.11

Three Major Highlights

1. Enterprise-grade identity authentication and multi-tenant management upgrades

• The Cloud Edition now fully supports OIDC sign-in, enabling seamless integration with your unified enterprise identity system and improving both security and convenience.
• The self-managed edition now allows customer names to be changed, and tenant names can be configured at initialization for more flexible multi-tenant management.

2. Programming language ecosystem expansion: full-stack D language analysis

• Support for analyzing D language applications, filling a gap in performance diagnostics for that language.
• Two new flame graph analyzers focused on garbage collection in D: they show allocation hotspots and object size distribution directly in reports so you can see where memory pressure comes from—not just a single coarse memory figure.

3. Deeper system-level diagnostics: three new analyzers

• New LuaJIT garbage collector analyzer (lj-gc-state): see LuaJIT GC configuration and live runtime state at a glance for targeted tuning in OpenResty-style workloads, instead of only wading through low-level counters.
• New connection-tracking analyzer (sys-nf-conntrack): lays out the kernel configuration and current state your system relies on when tracking every network connection—ideal when debugging “connections can’t keep up” or odd tracking-table behavior in network-heavy apps.
• New softirq analyzer (sys-softirq-stats): explains whether the machine is bogged down by kernel-side softirq work and points you toward practical tuning to ease whole-system stalls under high concurrency.

Other Important Updates

Security and operations enhancements

• Vulnerability scanning covers more vendors, broadening the reach of security protections.
• Support for cleaning up inactive agents to optimize resource management.

User experience improvements

• Mobile reports support pinpointing issues using both report ID and problem ID together (a two-key lookup).
• Announcement titles support permanent links for easier documentation and sharing.
• Refined dismissal of new-report notifications: mouse-wheel zoom is disabled and toolbar zoom buttons are added.

Stability fixes

• Fixed missing installation commands on Amazon Linux 2023.
• Fixed self-managed edition login form display issues and critical problems such as empty OIDC names.
• Fixed multiple issues in application detection to improve detection accuracy.

Performance optimizations

• Added indexes for application updates, significantly improving query performance.
• Updated related components to keep the technology stack current.

This release achieves major breakthroughs across enterprise integration capability, breadth of programming language coverage, and depth of system-level diagnostics, delivering a more comprehensive, professional performance analysis and troubleshooting solution.
