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 WorkOS?
WorkOS spent October giving IT admins control of Pipes and audit trails
After September's agent identity releases, Agent Auth and MCP Enterprise-Managed Authorization, WorkOS's October work is enterprise administration. Pipes, its third-party account connections, gained organization-wide provider setup by IT admins and multiple connected accounts per provider. Audit Logs can now generate events automatically from activity on WorkOS, and AuthKit and email branding can differ per application in one environment.

◆ 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.

WorkOS spent October giving IT admins control of Pipes and audit trails
◆ Current state
After September's agent identity releases, Agent Auth and MCP Enterprise-Managed Authorization, WorkOS's October work is enterprise administration. Pipes, its third-party account connections, gained organization-wide provider setup by IT admins and multiple connected accounts per provider. Audit Logs can now generate events automatically from activity on WorkOS, and AuthKit and email branding can differ per application in one environment.
◆ Where it's heading
The pattern is breadth inside large customers: several apps per environment, several accounts per provider, one admin configuring for everyone. Each release removes a reason an enterprise would need custom glue around WorkOS.
◆ Prediction
More Pipes administration controls look likely given two releases in eight days, but the entries do not name upcoming providers or features.
