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 Elasticsearch?

Elastic moves to 9.5 and takes cross-project search GA on Serverless.

Elastic Stack is now maintained on the 9.5, 9.4 and 8.19 lines, with patch releases arriving together across branches. The one substantive move is cross-project search reaching GA on Serverless, which links projects and queries them from one Discover or ES|QL session.

Prometheus Alertmanager vs Elasticsearch: 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.

Elastic moves to 9.5 and takes cross-project search GA on Serverless.

◆ Current state

Elastic Stack is now maintained on the 9.5, 9.4 and 8.19 lines, with patch releases arriving together across branches. The one substantive move is cross-project search reaching GA on Serverless, which links projects and queries them from one Discover or ES|QL session.

◆ Where it's heading

Serverless is where the feature work shows up: cross-project search and Azure Private Link both landed there in about a month. The self-managed lines are getting steady patch trains, which keeps 8.19 viable as a long-lived branch.

◆ Prediction

Expect further Serverless parity with self-managed cluster features, and continued patch trains across branches. The patch notes shown here do not support a more specific call.
