What is Prometheus Alertmanager?
Alertmanager 0.34.2 turns off CORS by default, breaking cross-origin API calls.
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.34.2 (October 29) stops sending CORS headers by default, so cross-origin calls to api/v2 now fail unless --web.cors.origin is set, and rebuilds with Go 1.26.10 to distrust the compromised eMudhra intermediates. 0.34.1 fixed inhibitions that could un-mute alerts, and 0.34.0 split auth and rate-limit failures out of the clientError metric reason.
What is Honeycomb?
Honeycomb is working on the first ten minutes, not just the incident
Honeycomb's latest releases focus on getting new users to value quickly. A guided setup wizard recommends MCP as the route for sending data, and Data Pulse (Beta) then reads incoming telemetry, describes the system and suggests questions to ask. Canvas keeps deepening alongside this: agent replies link directly to the charts they generate, and the GitHub connector now authorizes once per team. Agents can also create SLO Burn Alerts and reset budgets through MCP.

Prometheus Alertmanager
2.5INFRA · APIS
Alertmanager 0.34.2 turns off CORS by default, breaking cross-origin API calls.
◆ Current state
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.34.2 (October 29) stops sending CORS headers by default, so cross-origin calls to api/v2 now fail unless --web.cors.origin is set, and rebuilds with Go 1.26.10 to distrust the compromised eMudhra intermediates. 0.34.1 fixed inhibitions that could un-mute alerts, and 0.34.0 split auth and rate-limit failures out of the clientError metric reason.
◆ Where it's heading
The 0.3x line keeps shipping breaking changes outside major versions: metric reason splits in 0.34.0, per-group markers in 0.33.0 and now a CORS default in a patch. Operators need to read every release note, not just minors.
◆ Prediction
Expect 0.35.0 to carry further breaking changes in the vein of 0.33 and 0.34, though the entries do not say what it will contain.
Honeycomb
5.0INFRA · APIS
Honeycomb is working on the first ten minutes, not just the incident
◆ Current state
Honeycomb's latest releases focus on getting new users to value quickly. A guided setup wizard recommends MCP as the route for sending data, and Data Pulse (Beta) then reads incoming telemetry, describes the system and suggests questions to ask. Canvas keeps deepening alongside this: agent replies link directly to the charts they generate, and the GitHub connector now authorizes once per team. Agents can also create SLO Burn Alerts and reset budgets through MCP.
◆ Where it's heading
The agent-first direction now runs through onboarding as well as investigation. Recommending MCP over the OpenTelemetry SDK as the default path is the clearest signal yet that Honeycomb expects an agent to do the instrumentation. Write access for SLOs through MCP extends the same logic to alert management, while team-wide connectors remove setup work that each Canvas user previously had to repeat.
◆ Prediction
Data Pulse is in beta and is the obvious candidate for wider rollout, likely with more system types recognized. Further MCP write tools for monitoring objects would continue the pattern set by Burn Alerts.
