Changelog

Bug Fixes

• Routing policy expressions that reference undefined variables no longer fail validation. Variables can now be left undefined without blocking the expression from being saved.
• Queries using hasAll or hasAny filter operators now pass the value argument correctly, fixing cases where these filters returned incorrect results.
• Deleted service accounts now return a proper unauthenticated error code instead of a generic failure when their API key is used.

Maintenance

• The OpenTelemetry Collector has been upgraded to v0.144.3-rc.4.
• Cloud integration modules have been refactored with updated query parameter support and removal of deprecated underscore-prefixed attribute dashboards.
• SQLite connection max lifetime is now configurable, improving connection management under sustained load.
• Frontend onboarding data sources have been migrated from JSON to TypeScript, and asset imports now use the @ alias for cleaner path resolution.
• ClickHouse queries sent from dashboard panels are now obfuscated in telemetry to avoid leaking sensitive query content.

Bug Fixes

• The host list in Infrastructure Monitoring now correctly shows refresh status, and refresh interval queries no longer overlap with each other.
• Dormant metrics in the query range API now return a warning instead of an error, preventing unnecessary failures when querying metrics that haven't reported recently.
• Alert rules history no longer crashes when relativeTime is empty.
• Dashboard variables with special characters now fall back to the raw parameter if decodeURIComponent fails
• The having expression in the query builder now validates correctly before execution.
• Empty not() filter expressions are now handled gracefully instead of producing query errors.

Maintenance

• Cmd+click (or Ctrl+click) now works on all clickable items across the app, opening them in a new tab as expected.
• Deprecated v3/v4 rule format support and the v1 Metrics Explorer code have been removed.
• JSON Path indexing is now enabled for JSON log bodies, improving query performance on structured log data.

Bug Fixes

• Filtering traces by trace ID in the list view no longer returns duplicate spans or results from outside the selected time window. Previously, the trace_summary timerange override was applied incorrectly across query buckets, causing repeated and out-of-range results.
• Logs pipeline filters now correctly resolve manually entered attribute names that are not present in the filter suggestion dropdown. Previously, entering a field like ddtags Exists by hand would misclassify it as a column rather than an attribute, causing downstream processors such as regex parsers to fail silently.
• The normalize pipeline now runs first in the processing chain, ensuring consistent field formatting before other pipelines execute.
• PromQL queries that exceed the execution deadline now return a 504 Gateway Timeout instead of a misleading 400 Bad Request. The PromQL engine timeout is also now configurable via the prometheus.timeout setting (default: 2m).
• Charts on the Volume Details page in Infrastructure Monitoring now display proper legend labels instead of "undefined."
• Domain rows in External APIs now show a pointer cursor on hover, indicating they are clickable.
• Time series charts with isolated data points surrounded by null values on both sides render those points correctly instead of dropping them.
• Deleting an alert rule or planned maintenance entry that has associated dependencies no longer fails with a foreign key constraint error.
• Agent configurations no longer get stuck in the "In Progress" state indefinitely.
• Users with the Editor role can now access gateway APIs as expected.
• Checkout and billing errors now surface the actual downstream error message in the UI instead of a generic failure.

Maintenance

Patch release with internal fixes. No user-facing changes.

Bug Fixes

• The custom domain settings card (Cloud) no longer shows a confusing plan name label. The card now displays the workspace name and a copiable license key in the footer, and no longer renders empty space when no custom domain is configured.
• Querying a histogram metric that has not received data within the selected time range now returns a "not found" error with diagnostic details (including when the metric was last seen) instead of a generic "something went wrong" message.
• Switching a dashboard panel type from time series to table now loads the table data correctly. The right-side settings panel in edit mode is also scrollable again.
• Dashboard variables now retain their selected values when navigating back from the widget editor and when toggling between view and edit modes.
• Creating a new Slack notification channel no longer fails with a "no global Slack App URL set" error. This affected users who signed up before v0.115.0 and did not have an existing Slack channel configured.
• The default color for log severity_text entries (when no severity key is present) now uses a theme-appropriate background color, resolving poor contrast in dark mode.

Bug Fixes

• Quick filters now correctly highlight active selections when query keys include prefixes like resource.service.name.
• Opening the widget editor on dashboards imported from partially formed or LLM-generated JSON no longer crashes the threshold selector.
• Dashboard panel creation no longer fails when the underlying API response is unavailable; all panel types now handle missing data gracefully.
• Updating a dashboard variable no longer throws a crash caused by an attempt to modify read-only state.
• The filter dropdown on the trace waterfall view no longer overlaps the search bar when the browser is zoomed in.
• API calls made after a token refresh now correctly retry using the updated token across all pages.
• A planned downtime notification with a malformed description no longer crashes the Planned Downtime page.
• The app layout now uses the correct timer cleanup function, preventing potential issues in non-standard JavaScript environments.
• The selected y-axis unit in Logs, Meter, and Traces explorers is now preserved across reloads, back/forward navigation, and shared links.

Maintenance

• Dashboard panels with auto-refresh enabled no longer accumulate stale query cache entries in memory over time, preventing browser tab crashes on long-running dashboards.

Bug Fixes

• Editing the time range by typing directly into the custom time picker now applies your changes when closing the popover, instead of silently discarding them.
• PromQL-based dashboard panels no longer display internal attributes like __name__ and fingerprint in query results.
• Reverted the quick filters migration introduced in v0.114.0 to resolve issues it caused.

Maintenance

• Tooltip pinning has been reworked to support clicking on a data point across time series, bar, and histogram charts to keep the tooltip visible while inspecting values.

Bug Fixes

Dashboards

• Charts no longer leak memory due to canvas elements persisting across component re-mounts.
• Legend color picker now responds correctly under rapid interactions, and chart tooltips no longer leak memory on re-render.
• Dynamic variables that depend on textbox variables now load correctly even when the textbox value is empty.

Metrics Explorer

• Multiple queries using the same metric with no unit set are now correctly rendered as separate charts instead of being forced into one.
• Metric selection in the query builder now properly responds to blur and keyboard shortcuts (Cmd+Enter), fixing cases where aggregation options would not update after selecting a metric.
• Cmd+Enter now works in the summary tab, and key values can be expanded in full instead of loading five at a time.
• The most recently seen unit is now used instead of an arbitrary one, fixing incorrect unit labels on histogram count metrics.
• Errors are now surfaced to the user instead of failing silently.

Other

• Spatial aggregation queries are now validated before execution, preventing silently incorrect results from invalid configurations.

Maintenance

• SigNoz's frontend build system has been migrated from Webpack to Vite, reducing build times from 83 seconds to 10 seconds.
• Frontend bundle size has been further reduced by lazy-loading the syntax highlighter, moving antd-table-saveas-excel out of the main bundle, switching the Service Map to a lighter dependency, and caching the Intl number formatter.

Bug Fixes

• Clicking filter-in or filter-out options on JSON log body fields in Logs Explorer now works correctly — the detail drawer closes after applying a filter instead of dismissing the popover unexpectedly.
• Selecting and copying text in a log row in Logs Explorer no longer opens the log detail drawer.
• Creating an alert from the Logs Explorer list view now works correctly, with the query automatically converted to a format compatible with time-series alerting.
• The frequency graph in Logs Explorer now reserves red exclusively for actual error states and no longer shows red for logs with blank or unmapped severity.
• Several layout issues in the Logs Explorer column view are now fixed: the first column no longer takes disproportionate space, the table body now uses available width when fewer than three columns are visible, search fields in log details open expanded by default, and the space-indicator column is no longer accidentally draggable.
• Filter attributes in Logs Pipelines now correctly reflect the selected data type. Selecting an attribute of type tag now sends tag in the query instead of incorrectly sending resource.
• Dashboard variables chained in sequence now load correctly even when the first variable in the chain does not have the "ALL" option enabled.
• Dashboard threshold warnings now correctly reflect the selected Y-axis unit, fixing cases where thresholds and the Y-axis unit selector used different conversion logic and produced incorrect warnings.
• The "Show IP Addresses" toggle in External API Monitoring now correctly applies to the domain list, including entries returned as scalar data.
• SigNoz's initial load time is now significantly faster with the main JavaScript bundle reduced from ~10MB to ~3.4MB through lazy page loading.

Bug Fixes

Dashboards & Panels

• Chart manager table now displays aggregation values (Avg, Sum, Max, Min) using the panel's configured y-axis unit instead of raw numbers
• Dashboard dynamic variables now load their options correctly on first page load
• Switching between panel types no longer causes jerky chart transitions
• Time series charts with only a single data point now render that point as a visible dot instead of an empty chart
• Tooltips in uPlot charts now appear and snap correctly when hovering within range of a data point
• The last row in the overview table is no longer hidden due to a layout overflow issue

Team Management

• Inviting team members no longer shows validation errors on empty rows; only rows where an email or role has been entered are validated. The submit button is also renamed from "Complete" to "Send Invites" for clarity.

Logs

• Queries using IN, NOT IN, BETWEEN, or NOT BETWEEN operators on JSON array fields in the log query builder now return correct results

External API Monitoring

• Endpoint counts now reflect the correct values when spans use url.full instead of http.url for the URL attribute
