What is Prometheus?
Prometheus 3.14 ships OCI service discovery and start-timestamp rate extrapolation
Prometheus is in steady maintenance and incremental feature mode across two active release tracks: 3.13 LTS and 3.14 stable. The 3.14.0 release adds Oracle Cloud Infrastructure service discovery, promotes duration expressions from feature-flagged to default, and introduces an experimental start_timestamp function that enables more accurate rate extrapolation. Recent cycles have also been heavy on security dependency updates and TSDB correctness fixes — the head-chunk cache bug in 3.13.1 was a real correctness risk for range queries after compaction.
What is Rivet?
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

Prometheus 3.14 ships OCI service discovery and start-timestamp rate extrapolation
◆ Current state
Prometheus is in steady maintenance and incremental feature mode across two active release tracks: 3.13 LTS and 3.14 stable. The 3.14.0 release adds Oracle Cloud Infrastructure service discovery, promotes duration expressions from feature-flagged to default, and introduces an experimental start_timestamp function that enables more accurate rate extrapolation. Recent cycles have also been heavy on security dependency updates and TSDB correctness fixes — the head-chunk cache bug in 3.13.1 was a real correctness risk for range queries after compaction.
◆ Where it's heading
Prometheus is methodically expanding its service discovery surface (OCI joins the roster) while refining PromQL's precision for long-range and histogram queries. The start-timestamp work (experimental in 3.14) addresses a known limitation in rate extrapolation that has produced systematically off results in low-scrape-frequency setups. The histogram start-timestamp encoding feature, also experimental, suggests the team is working toward more consistent histogram behavior across the scrape lifecycle. OTLP integration continues to get hardening work — the label collision warning in 3.14 is a response to a real operational pain point for teams ingesting OTel data.
◆ Prediction
The start-timestamp rate extrapolation feature will graduate from experimental in 3.15 if community feedback is positive — it's the kind of correctness improvement that gets adoption quickly once users verify it against their own data. OTLP improvements are likely to continue as OTel adoption grows and label sanitization edge cases surface.
Rivet
7.5DEVOPS
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
◆ Current state
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
◆ Where it's heading
Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.
◆ Prediction
Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.
