What was released

This section summarizes what was released this week.

Fast lane GA features

These features are generally available for all customers. Slow lane customers and tenants will have these features automatically enabled on August 5, 2026.

ai-sre: AI-SRE chat now accepts PDF and text file attachments — share log files, configs, or documents directly in the agent conversation. This enables document-grounded investigation without manually copy-pasting content into the chat.
datasets: Acceleration Manager and dataset landing pages now show "true staleness" reasons — instead of a generic "stale" badge, you see the specific root cause such as "source pipeline stopped" or "acceleration paused" so you can act immediately.
datasets: Filter datasets by correlation tag using hasCorrelationTag() in the dataset search API. Enables automated workflows and AI-SRE tooling to scope dataset discovery to relevant services or environments without scanning the full catalog.
dashboards: Series zoom — click a chart legend item to isolate that series. Reduces visual clutter in dense multi-series charts, making it easier to spot anomalies in a single metric without losing overall context.

Slow lane GA features

These features are enabled for all slow lane customers and tenants today.

auth: Ingest tokens can now be rotated in-place via the API — token IDs are preserved, eliminating the need to recreate tokens and update all consumers.
dashboards: Per-card custom time ranges now available across all environments.
expression-builder: Filter condition input is now capped at ~4 rows by default with an expand button for longer expressions.
opal: null is now a native OPAL keyword — use it directly in filter expressions instead of variant_null().

Public preview and private preview features

Private preview () features are available by invitation only. Public preview () features are available by inquiry.

tags: Global tag management — a full searchable table of all workspace correlation tags with detail-level inspection.
metrics: Log-derived metrics is now available in public preview.

Bug fixes

The following issues are fixed in this week's release:

dashboard: Fixed drilldown links not showing in the single card editor (OB-62004)
dashboard: Fixed related rail not opening on pivot in the new dashboard experience (OB-61969)
datatable: Fixed reverseColors not applying in conditional formatting rules (OB-59845)
filtering: Fixed null values not appearing in OPAL value popup suggestions (OB-62123)
filtering: Fixed filter lint not including preceding-step OPAL as context (OB-62132)
monitors: Fixed seasonal anomaly detection producing incorrect bounds when monitors use group-by tags (OB-61889)
opal: Fixed filter value autocomplete not escaping quotes correctly (OB-62035)

REST API changes

The following changes are reflected in the Observe REST API as of this release.

New

MonitorV2NoDataRule: New schema for configuring no-data alarms on monitors. Accepts expiration (how long the alarm persists before auto-resolving, defaults to ~24 hours) and threshold (threshold configuration matching the monitor's regular rules).
MonitorV2Definition.noDataRules: New array field on monitor definitions. Attach up to one MonitorV2NoDataRule per threshold monitor — fires at NoData severity when no data arrives for the full lookback window.

Updated

DatasetStalenessReason (enum descriptions): All six staleness reason values now include actionable guidance. For example, SlowAcceleration previously described as "de-prioritized because not queried recently" now reads "Acceleration can't keep up with the freshness goal; optimizing the dataset's query or reducing its data volume can help."

Coming soon

The following GA features are already available for fast lane customers, and will be enabled for slow lane customers and tenants next week.

ai: Claude Fable 5 (Sonnet) added as a model option for AI SRE.
ai-sre: OPAL query cards in AI-SRE now available via MCP.
opal: Autocomplete suggestions are now grouped into labeled sections for easier browsing.
tags: Correlation tag inspection rail now shows enhanced tag details and richer appearance.
trace-explorer: Ask o11y button in the trace details to summarize the trace.
trace-explorer: Add columns button to show additional attributes in the Trace Explorer.
