v2.17.0 ships a security fix for XSS in the UI, two major UI features (side panel span details, trace log aggregation), and several backend stability fixes including a panic guard and clock skew correction.

• securityUpdate UI immediately to fix XSS vulnerability

  The UI was rendering user-supplied trace data using innerHTML, which opens the door to XSS if trace attribute values contain malicious HTML. This is fixed by switching to textContent. If you expose Jaeger UI to users who can influence span data (e.g., shared environments, multi-tenant setups), treat this as a priority upgrade. Pull the v2.17.0 image and redeploy.

• breakingClock skew fix changes span end timestamps — verify your trace data expectations

  The clock skew adjuster previously only corrected span start times, leaving end timestamps unadjusted. Now both are corrected. For teams with strict SLO calculations or latency assertions based on adjusted trace data, this behavioral change could shift computed durations. Validate your dashboards and alerting rules against real traces after upgrading.

• enhancementSide panel span view reduces trace analysis friction

  Span details previously expanded inline, collapsing the trace timeline context. The new side panel mode keeps the timeline visible while inspecting a span. Useful immediately for deep trace debugging — no configuration needed, just click a span in the UI. Worth showing to your team as a workflow improvement.
