Prometheus Alertmanager vs Shuffle: at a glance
What is Prometheus Alertmanager?
Alertmanager 0.35 adds a gRPC API and a new UI, and breaks event recorder configs
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.35.0 (November 9) is the largest release in the feed: an experimental ConnectRPC API (Connect, gRPC and gRPC-Web) beside api/v2, a new Mantine UI at /ui/, Slack thread replies for alert updates, and breaking changes that require named event recorder outputs, move its output to an events/v2 schema and promote auto-gomemlimit to a plain flag. It follows 0.34.2, which turned CORS off by default.
What is Shuffle?
Shuffle tags builds almost daily, but the notes are empty.
Shuffle has tagged six 2.3.1 builds since November 3: release candidates 4 to 6 and three nightly builds. Only rc4 lists a change, a fix for a frontend crash; the rest link to commit comparisons. The more substantive rc1 in October handled AI agent actions in hybrid worker setups.

Alertmanager 0.35 adds a gRPC API and a new UI, and breaks event recorder configs
◆ Current state
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.35.0 (November 9) is the largest release in the feed: an experimental ConnectRPC API (Connect, gRPC and gRPC-Web) beside api/v2, a new Mantine UI at /ui/, Slack thread replies for alert updates, and breaking changes that require named event recorder outputs, move its output to an events/v2 schema and promote auto-gomemlimit to a plain flag. It follows 0.34.2, which turned CORS off by default.
◆ Where it's heading
The project is replacing its interfaces in parallel rather than in place: a new API generation and a new UI now run alongside the old ones. The event recorder introduced in 0.33 is being reshaped with breaking schema changes, so anything consuming it is tracking a moving target.
◆ Prediction
Expect 0.35.x patch releases fixing fallout from the breaking changes, and further services added to the ConnectRPC API beyond the initial status service.

5.0INFRA · APIS
Shuffle tags builds almost daily, but the notes are empty.
◆ Current state
Shuffle has tagged six 2.3.1 builds since November 3: release candidates 4 to 6 and three nightly builds. Only rc4 lists a change, a fix for a frontend crash; the rest link to commit comparisons. The more substantive rc1 in October handled AI agent actions in hybrid worker setups.
◆ Where it's heading
The project is iterating toward 2.3.1 with frequent builds, and the October notes show the work is about making AI agent steps run reliably in workflows. The empty release notes make it hard to see what each build changes.
◆ Prediction
A 2.3.1 final release looks close given the run of release candidates and nightlies, though the entries do not say what it will contain beyond fixes.
