What is SigNoz?
SigNoz is rebuilding its surfaces so agents can drive them, not just humans.
SigNoz is in a broad platform-hardening phase: dashboards rebuilt on the CNCF Perses schema, PromQL brought into conformance with Prometheus, Infrastructure Monitoring rebuilt around Kubernetes investigation, and an integration catalog expanding almost weekly. GCP metrics now land next to the rest of a team's telemetry with pre-built dashboards rather than requiring a trip to Cloud Monitoring. The v1 alert history endpoints are being removed over a security issue, with a documented v2 migration path.
What is waldo?
waldo keeps shedding dependencies while teaching its diff engine new object systems
waldo produces the object comparisons that testthat failure messages are built from. The recent releases do two things: drop dependencies - tibble, rematch2 and fansi have all gone - and extend comparison to object systems that did not exist when it was written, notably S7. Correctness of missing-value and tolerance semantics accounts for most of the rest.

SigNoz is rebuilding its surfaces so agents can drive them, not just humans.
◆ Current state
SigNoz is in a broad platform-hardening phase: dashboards rebuilt on the CNCF Perses schema, PromQL brought into conformance with Prometheus, Infrastructure Monitoring rebuilt around Kubernetes investigation, and an integration catalog expanding almost weekly. GCP metrics now land next to the rest of a team's telemetry with pre-built dashboards rather than requiring a trip to Cloud Monitoring. The v1 alert history endpoints are being removed over a security issue, with a documented v2 migration path.
◆ Where it's heading
Two threads run through the quarter. The first is compatibility as a migration argument — matching Prometheus semantics exactly and adopting an open dashboard specification both lower the cost of moving to SigNoz from whatever is already installed. The second is agent-readiness: the dashboard rebuild explicitly targets structured, token-light agent edits, and Noz keeps picking up context handling, so the operator SigNoz designs for is increasingly not a person.
◆ Prediction
Expect the schema-first treatment to spread to the other configurable surfaces, with alerts and saved views the obvious candidates, and the onboarding catalog to keep growing at its weekly clip. The v1 alert history endpoints should disappear within a release or two.

waldo keeps shedding dependencies while teaching its diff engine new object systems
◆ Current state
waldo produces the object comparisons that testthat failure messages are built from. The recent releases do two things: drop dependencies - tibble, rematch2 and fansi have all gone - and extend comparison to object systems that did not exist when it was written, notably S7. Correctness of missing-value and tolerance semantics accounts for most of the rest.
◆ Where it's heading
This is a package deliberately shrinking its footprint while widening what it understands. Since it is imported by testthat, every dependency it drops is one fewer package in the check environment of most of CRAN, which is clearly the motivation. The comparison logic itself changes only when R gains a new way to represent objects.
◆ Prediction
Expect S7 support to deepen from basic to complete as S7 adoption grows, and further dependency removals; the diff algorithm itself looks settled.
