Prometheus Alertmanager vs Mergify: at a glance
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 Mergify?
Mergify's merge queue now hunts the breaking PR by rerunning failed tests first
Mergify shipped more than a dozen changes in the last week of October. On the merge queue, failed batches now run the failing tests first in each split, stacked PRs enter the queue together, scope capacities work with Bazel, Pants and Turborepo scopes and patterns, and batch merge commits name the PRs they land. Test Engine gained Minitest, Jest and Mocha plugins and a setup path driven by a coding agent. Jinja2 expressions in configuration stopped being evaluated on October 31.

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.

Mergify's merge queue now hunts the breaking PR by rerunning failed tests first
◆ Current state
Mergify shipped more than a dozen changes in the last week of October. On the merge queue, failed batches now run the failing tests first in each split, stacked PRs enter the queue together, scope capacities work with Bazel, Pants and Turborepo scopes and patterns, and batch merge commits name the PRs they land. Test Engine gained Minitest, Jest and Mocha plugins and a setup path driven by a coding agent. Jinja2 expressions in configuration stopped being evaluated on October 31.
◆ Where it's heading
Mergify is tying its merge queue to test data: Test Engine knows which tests fail, and the queue uses that to bisect faster with less CI. Monorepo build tools and stacked PRs are now first-class queue inputs.
◆ Prediction
More queue behavior driven by Test Engine results is likely, given that Fail First and the new test plugins shipped the same week.
