This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Releases

@hyperdx/cli@0.8.1

Patch Changes

• d7df729: chore: GitHub links (changelog, support, package metadata) now point at ClickHouse/ClickStack, and docker-compose.yml pulls the app image as clickhouse/clickstack
• e2754d2: fix: use SHA256 instead of MD5 for JSON row lookup WHERE clauses so row
  details and drill-down work on FIPS-enabled ClickHouse deployments

@hyperdx/api@2.44.0

Minor Changes

• cd0e9ed: feat: add optional titleEmoji webhook option; false removes the emoji prefix from notification titles sent through that webhook

• 5b0d074: feat: self-instrument with @clickhouse/clickstack-node and
  @clickhouse/clickstack-browser instead of @hyperdx/node-opentelemetry and
  @hyperdx/browser

  HyperDX's own telemetry changes shape. HTTP spans use the stable semantic
  convention keys (http.request.method, http.response.status_code,
  url.full). pino records come from the @opentelemetry/instrumentation-pino
  scope with real severity numbers instead of the node-logger scope with
  severity number 0. Console capture covers every console call in the API, and
  browser console output is recorded as log records instead of spans. Uncaught
  exceptions are recorded as FATAL log records, and API errors as an exception
  event on the Express span instead of a separate error span.

  Browser telemetry records the user as user.id, user.email and user.name
  instead of userEmail and userName, keeps the team name as teamName, and no
  longer records a user navigated action. Browser fetch and XHR spans no longer
  record request and response headers or bodies. Browser sessions restart once
  after the upgrade. The per-signal browser endpoints and
  NEXT_PUBLIC_OTEL_RESOURCE_ATTRIBUTES work as before. Browser traces and logs
  are now sent gzip-compressed every 5 seconds. If the browser sends to a
  collector other than ClickStack's, its CORS allowed_headers must be "*" or
  include content-type and content-encoding (and authorization), and a proxy
  in front of it must forward Content-Encoding unchanged.

  The Next.js server now sends its own telemetry in production builds too, not
  only under next dev, when HYPERDX_API_KEY or OTEL_EXPORTER_OTLP_HEADERS is
  set. HDX_EXPORTER_ENABLED=false turns it off along with browser telemetry. It
  reports under its own service name, the configured one plus -next
  (hdx-oss-app-next in the docker-compose app service and when no name is
  set), so its spans stay apart from the API's and the browser's. The HyperDX
  images now default OTEL_SERVICE_NAME to hdx-oss-app. Each /api request
  adds Next.js server spans for the proxy hop. Requests for build and public/
  assets, such as /_next/static/*, /__ENV.js and /pyodide/*, are not traced.

  HYPERDX_API_KEY still enables self-instrumentation. Without
  OTEL_EXPORTER_OTLP_ENDPOINT, server-side self-telemetry now goes to
  http://localhost:4318 instead of https://in-otel.hyperdx.io, so set the
  endpoint explicitly. HDX_NODE_* variables are no longer read. For request
  headers and bodies set OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_* and
  CLICKSTACK_CAPTURE_HTTP_BODY.

• 349fc21: feat(mcp): add clickstack_describe_table to list the tables in a database and describe a table that is not a registered source (columns, keys, engine, skipping indices, approximate size, optional row sample)

• 0eec5e1: feat: Describe PromQL sources in MCP and hide them when PromQL is disabled

  clickstack_describe_source now returns the label names and metric names of a PromQL source, from either a ClickHouse TimeSeries table or a Prometheus-compatible endpoint, instead of a column schema. clickstack_list_sources and clickstack_describe_source show which backend a PromQL source uses, and for TimeSeries tables explain how to read them with clickstack_sql. Prometheus endpoint sources no longer show their placeholder table. When ENABLE_PROMQL is off, MCP hides PromQL sources from listing, describing and deleting, and clickstack_save_source no longer accepts kind: "promql".

• 95fa364: feat(mcp): support setting a dashboard's savedFilterValues via the MCP dashboard tools

• c792850: feat: filter the v2 list alerts endpoint by tag, search, source and state

Patch Changes

• 30b1494: feat: add an internal extension point for alert detection strategies; threshold alerts are evaluated as before, and the alerts.evaluate metric now carries an alert_evaluator attribute

• 0453aa1: fix: A grouped alert whose group vanishes from the data now resolves with the group's values in {{attributes.*}} (alert title and message) and {{var.*}} (webhook body)

• 5b0d074: fix: let browsers cache the collector's CORS preflights for 10 minutes

  The OTLP receiver now answers preflights with Access-Control-Max-Age: 600.
  Without it, browsers cached a preflight for only 5 seconds, which is how often
  the browser SDK exports, so about half of its requests were preflights.

• 769c0de: fix: ignore team and createdBy in dashboard and saved search PATCH bodies so they can't be moved to another team or have their owner rewritten

• 48c8379: docs: Document minAutoGranularity on metric and PromQL sources in the external
  API

  GET, POST and PUT /api/v2/sources already accepted and returned
  minAutoGranularity, but the OpenAPI spec omitted it, so clients generated from
  the spec dropped or rejected the field.

• 5584f84: fix: make clickstack_event_patterns drill-down snippets executable

  Each pattern's whereSnippet is now a SQL predicate (whereLanguage: "sql") that keeps the template's token order and variable positions and includes the caller's filter and the source table filter, so passing it to clickstack_search returns the pattern's events. Before, a template like Sending <*> rows produced Body:"Sending rows", which matched nothing, and map fields produced Lucene that failed to parse. bodyExpression now also accepts JSONExtractString(<column>, '<key>', ...) to mine a field inside JSON bodies, and the tool reports sample coverage and the actual trend bucket interval and boundaries.

  clickstack_event_patterns, clickstack_emerging_signals and dashboard event-pattern tiles now apply the log source's tableFilterExpression, so their counts can drop for sources that set one. minePatterns now reports each cluster's own template; before, it could report the template of a different same-length cluster that some members did not fit.

• 253a690: docs: MCP tool descriptions and the query guide now recommend the quoted Lucene
  form field:"value" for exact matches, and bare terms or phrases for log body
  text, so agents keep the primary key and the text index

• 66e3941: feat: MCP query_tile and query_tiles run PromQL tiles against Prometheus endpoints and ClickHouse TimeSeries tables

• 7e85229: feat: MCP clickstack_promql tool runs PromQL against a PromQL source, and the MCP prompts and instructions cover PromQL sources, tiles and label filters while PromQL is enabled

• 9093282: fix: Refuse Prometheus endpoint responses over 8 MB in MCP PromQL label lookups and queries, instead of buffering them whole

• 53bf540: fix: MCP query_tile returns PromQL table and histogram heatmap tiles in the rows the dashboard draws

• 917c9ca: feat: MCP dashboard tools read and write PromQL tiles and PROMETHEUS_LABEL filters when PromQL is enabled, and hide but keep them when it is disabled

• d08b2fa: feat(mcp): clickstack_sql accepts a queries array to run up to 10
  independent queries in parallel under a shared 60s deadline. Each query reports
  its own ok/error/timeout status, so one failing query does not fail the
  others. Single-query calls with sql behave as before.

• a13c80e: feat(mcp): clickstack_table takes optional limit and having, and orders grouped results by the first select item, descending, when no orderBy is given

• 0262822: fix: MCP tool responses that are over the size budget now shorten long strings with a …(+N chars) suffix instead of replacing them, say what was trimmed in trimNotes, and clickstack_event_patterns / clickstack_emerging_signals drop samples and shorten long patterns before cutting whole patterns, so the requested topN survives when it can

• 442d6df: fix: refresh cached table columns after 5 minutes

  The shared metadata cache kept each table's DESCRIBE result for the life of
  the process, so the API did not see columns added with ALTER TABLE, such as
  new MATERIALIZED columns, until it restarted. Cached columns now expire after 5
  minutes. Other cached metadata is unchanged.

• eb2439e: fix: leave metric points with no recorded value out of charts and alerts

  When a scraped series goes away or a scrape fails, the collector's prometheus
  receiver sends a point flagged "no recorded value" (a Prometheus staleness
  marker), and the ClickHouse exporter stores it as zeros. Metric charts and
  alerts read it as a real value: a gauge's min and avg dropped and count
  included the series that went away, and a counter or histogram that came back
  after the marker counted its whole total again. Metric queries now skip points
  with this flag.

• 0eec5e1: fix: Authenticate to Prometheus connections whose host includes credentials

  A Prometheus connection host such as http://user:pass@prometheus:9090 made every PromQL query fail with "Failed to reach Prometheus", because fetch rejects URLs that carry credentials. The credentials are now sent as a Basic auth header.

• 0a5237e: fix: reject alerts on dashboard tiles the alert checker never evaluates (PromQL
  tiles, and builder tiles with unsupported display types), and drop them when a
  dashboard is saved

• b7b4d95: fix: update systeminformation to 5.33.19

  The root resolutions pin let the lockfile keep systeminformation 5.30.7, which
  has known command injection advisories, including two high-severity ones in
  networkInterfaces() on Linux (GHSA-5xpp-75jx-m839, GHSA-hvx9-hwr7-wjj9). The
  API installs it through @opentelemetry/instrumentation-host-metrics, which
  asks for ^5.31.6, but the old pin held it at 5.30.7. The pin now starts at
  5.33.19, the newest 5.x release, which fixes all of them.

• b1d4e60: fix: PromQL label lookups (dashboard variables, label autocomplete) now work on TimeSeries tables of schema version 8, the default from ClickHouse 26.10. These keep each series' time range in a separate time ranges table instead of the tags table's min_time/max_time, so match[] failed with "requires store_min_time_and_max_time = 1" and time-bounded lookups read the whole tags table.

• 90302c7: fix: Block generic and incident.io webhooks whose hostname resolves to a private or reserved address. The check runs on the address actually dialed, so it also covers DNS rebinding. Self-hosted setups that send webhooks to internal hostnames must add them to WEBHOOK_HOSTNAME_ALLOWLIST.

Minor Changes

• 142c9cc: feat: narrow ad hoc dashboard filter suggestions with a condition

  An ad hoc filter on SQL sources can now carry a SQL or Lucene "Keys and values
  filter", like a queried filter's dropdown values filter, that limits the rows
  its keys and values are suggested from. It can reference the dashboard's other
  variables. While it references a required filter with nothing selected, the ad
  hoc filter can't add or edit conditions and names the filter it is waiting on.
  Failed suggestions now show the database's error message.

• cd0e9ed: feat: add optional titleEmoji webhook option; false removes the emoji prefix from notification titles sent through that webhook

• 5b0d074: feat: self-instrument with @clickhouse/clickstack-node and
  @clickhouse/clickstack-browser instead of @hyperdx/node-opentelemetry and
  @hyperdx/browser

  instead of userEmail and userName, keeps the team name as teamName, and no

  record request and response headers or bodies. Browser sessions restart once

  headers and bodies set OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_* and
  CLICKSTACK_CAPTURE_HTTP_BODY.

• af17e8f: The app always uses ClickStack branding. Brand selection, the HyperDX palette, and the font picker are removed. Light, dark, and system color mode stay in Preferences.

• dd8c2e4: feat: Pick a time zone for the search and dashboard pages from the time picker, overriding the time zone in User Preferences. The picker shows the zone it uses, and the choice is kept in the URL and in links from charts and tables

Patch Changes

• 7de661b: feat: Row side panel summarizes clicks, navigations and console messages from OpenTelemetry browser SDKs, and navigation rows no longer show an HTTP Request section

• ab36d4e: feat: publish the HyperDX image as clickhouse/clickstack alongside
  hyperdx/hyperdx, matching the other clickhouse/clickstack-* images. Release
  workflows no longer log into ghcr.io, which received no pushes.

• f56d4ad: fix(app): use the ClickStack hexagon and bolt mark in the logo, the collapsed nav, and the favicon.

• d7df729: chore: GitHub links (changelog, support, package metadata) now point at ClickHouse/ClickStack, and docker-compose.yml pulls the app image as clickhouse/clickstack

• f56d4ad: fix(app): open the full nav over the page on compact viewports. On narrow screens the sidebar toggle now opens the full nav as an overlay instead of doing nothing.

• 513b237: fix: start the trace waterfall higher in the side panel

  Trace spans no longer repeat their name in a box under the panel title, or the
  service as a chip next to the metadata row that already shows it. The
  "⌘/Ctrl + scroll to zoom" hint moves into the timeline's top-left corner
  instead of taking its own row. Long span names that the title truncates keep
  the box. Log panels keep their body box and service chip.

• e2754d2: fix: use SHA256 instead of MD5 for JSON row lookup WHERE clauses so row
  details and drill-down work on FIPS-enabled ClickHouse deployments

• 5abf27e: Saving a search no longer reloads the page: the new saved search is opened with
  a client-side navigation, which also fixes the 404 this caused on the static
  ClickStack build.

• 04f55d1: feat: Exception panel parses JavaScript stack traces from OpenTelemetry SDKs into frames, with a section per Caused by: error

• d0dd06f: fix: count legacy STATUS_CODE_ERROR spans as errors on the service map and trace
  waterfall

• 41b2b74: feat: fall back to server MergeTree settings to detect persisted _block_number and _block_offset columns when the table's CREATE query omits them

• 442d6df: fix: refresh cached table columns after 5 minutes

  with this flag.

• 9df8b8d: fix: bump next to 16.4.3 so builds no longer fail intermittently when Google Fonts returns extensionless font URLs

• ec0db7a: fix: Creating an alert from the search page asks for one name, not two. An unsaved search is named once in the alert modal's header and the alert inherits that name and its tags; on a saved search the alert's own name field is labelled "Alert name" and shows the inherited name as its placeholder instead of pre-filling a duplicate.

• 467c167: feat: A pinned filter collapsed in the search sidebar stays collapsed the next
  time the source loads, instead of always opening

• 6468dad: fix: keep session replay events from different page loads apart

  Browser SDKs up to @clickhouse/clickstack-browser 1.2.0 number replay events
  from 1 again on every page load. When a page closed before all chunks of a large
  event were sent, its leftover chunk could be joined with a later page's event of
  the same number. That page's snapshot then failed to parse and did not render.
  Chunks are now grouped by event number and full-precision timestamp, and replay
  rows are ordered by the full-precision timestamp, so rows of two page loads in
  the same second no longer interleave.

  The app's own browser telemetry now uses @clickhouse/clickstack-browser 1.2.1,
  whose replay event numbers no longer repeat across page loads.

• 86cd38b: fix: only use the key-only row details lookup when the table persists both _block_number and _block_offset. A lone block column (e.g. a server-wide enable_block_offset_column) is not unique with a second-precision primary key and could open the wrong row; it is now only added as a tiebreaker to the full-row lookup.

• 82b2104: fix: show a loader while row details load

  Expanded search rows and the trace viewer's span details showed "Empty" or "No
  body for this event." while the row was still loading. They now show a loader
  until the row arrives.

• 3a412e4: fix: run the row details query once when opening a row

  The side panel ran the same SELECT * row query twice: once for the panel, and
  again when its Overview or Column Values tab mounted. A row that was found is
  now reused from the cache, so the tab and later tab switches do not query it
  again. A different row or source still runs the query, and a row that was not
  found is looked up again.

• 78143c8: feat: on ClickHouse Cloud, read system.shared_merge_tree_settings when detecting _block_number and _block_offset columns, falling back to system.merge_tree_settings per key

• 4e93ae5: fix(app): render the ClickStack name as text in the expanded sidebar, 8px from the logo symbol.

• 2bad9af: refactor: use the click-ui Separator instead of the Mantine Divider in the
  Team Settings sections.

• af75b2b: feat: Trace waterfall shows OpenTelemetry browser SDK request timings as dots on fetch and XHR spans, and the click that triggered a browser trace

• 4e93ae5: fix(app): use the new favicon set, including an SVG, in the browser tab, bookmarks, and touch icon.

• dc58efd: fix: The app no longer crashes on load in browsers that report a POSIX-style language such as en-US@posix

@hyperdx/otel-collector@2.44.0

Patch Changes

• 5b0d074: fix: let browsers cache the collector's CORS preflights for 10 minutes

  The OTLP receiver now answers preflights with Access-Control-Max-Age: 600.
  Without it, browsers cached a preflight for only 5 seconds, which is how often
  the browser SDK exports, so about half of its requests were preflights.

• 8384fe6: perf: compress the seed schemas with ZSTD(3) instead of ZSTD(1)

  The seed schemas pinned ZSTD(1) on almost every column. Level 3 gives a better
  compression ratio at a small insert-time CPU cost, without affecting reads, and
  it is the default codec of ClickHouse since 26.9. It is pinned explicitly so
  that older ClickHouse versions, whose default is LZ4, get it too. Delta
  codecs drop their byte-size argument, which ClickHouse infers from the column
  type. Only newly created tables are affected; existing tables keep their codecs.

• 7021810: feat: session ID columns, session.id from rum.sessionId, severity text

  The hyperdx_sessions seed adds materialized rum.sessionId and session.id
  columns with skip indexes, and the otel_logs seed adds a materialized
  session.id column with a skip index, so session queries no longer read the
  attribute maps. Only newly created tables get them; existing tables need an
  ALTER TABLE ... ADD COLUMN to benefit.

  Spans, logs and session replay events from older @hyperdx/browser SDKs, which
  carry the session id only in the rum.sessionId resource attribute, now also
  get the OpenTelemetry session.id attribute. An existing session.id is never
  overwritten and rum.sessionId is kept. If you override pipeline processors:
  lists in CUSTOM_OTELCOL_CONFIG_FILE, add transform/session_id to keep this.

  Logs that carry a severity number but no severity text, such as those from the
  new browser SDK, now get the matching level text (info, error, ...) instead
  of an empty level. Severity text set by the producer is never overwritten.
