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 NetBox?

NetBox 4.7's patch run fixes a token leak and a broken restore path.

Four 4.7 patches followed the September 4.7.0 release. 4.7.1 reinstalled hierarchical-path triggers that a pg_dump restore silently dropped, 4.7.2 stopped background bulk requests recording plaintext API tokens in job results, 4.7.3 was a REST and GraphQL performance release, and 4.7.4 adds change-log IDs to webhook payloads, fixes the circuit status GraphQL enum and warns about a thumbnail storage change.

Prometheus Alertmanager vs NetBox: editorial side-by-side

P2.5

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.

5.0

NetBox 4.7's patch run fixes a token leak and a broken restore path.

◆ Current state

Four 4.7 patches followed the September 4.7.0 release. 4.7.1 reinstalled hierarchical-path triggers that a pg_dump restore silently dropped, 4.7.2 stopped background bulk requests recording plaintext API tokens in job results, 4.7.3 was a REST and GraphQL performance release, and 4.7.4 adds change-log IDs to webhook payloads, fixes the circuit status GraphQL enum and warns about a thumbnail storage change.

◆ Where it's heading

The ltree migration in 4.7.0 is still generating follow-up work, and the patch notes are candid about what broke. Performance work on REST serialisation and GraphQL has been steady across the line, and event payloads are getting richer for automation users.

◆ Prediction

Expect further 4.7.x patches on a two-week rhythm with more API performance fixes; the entries don't show what 4.8 will contain.
