What is Prometheus?

Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.

Prometheus is maintaining a 3.13 LTS line and a 3.5 line with security-only releases while 3.14 develops. The LTS patches have been narrow and serious — a head-chunk cache returning samples from the wrong chunk after truncation, a SIGBUS crash when the active query tracker's disk fills, plus CVE-driven dependency bumps in golang.org/x/text and gRPC. The 3.14.0 release candidate is where the feature work sits: duration expressions on by default, first_over_time promoted out of the experimental flag, and Oracle Cloud Infrastructure service discovery added.

What is Redis?

Redis stopped writing about the AI memory tier and shipped a feature store.

The visible feed is dominated by developer-education content - RAG chunking, speculative decoding, prefill versus decode, agents versus workflows - all arguing that Redis is where AI systems keep state. Underneath it sit the actual releases: Redis Feature Form, an enterprise feature store for production ML; persistent real-time memory for Google ADK agents; Redis Insight 3.2.0 connecting to Azure Managed Redis with Entra ID; native OpenTelemetry metrics in the client libraries; and client-side geographic failover for Active-Active. Nothing in this feed has moved since late April.

Prometheus vs Redis: editorial side-by-side

Prometheus logo5.0

Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.

◆ Current state

Prometheus is maintaining a 3.13 LTS line and a 3.5 line with security-only releases while 3.14 develops. The LTS patches have been narrow and serious — a head-chunk cache returning samples from the wrong chunk after truncation, a SIGBUS crash when the active query tracker's disk fills, plus CVE-driven dependency bumps in golang.org/x/text and gRPC. The 3.14.0 release candidate is where the feature work sits: duration expressions on by default, first_over_time promoted out of the experimental flag, and Oracle Cloud Infrastructure service discovery added.

◆ Where it's heading

PromQL is the centre of gravity. Features enter behind promql-experimental-functions or a dedicated flag, get renamed once while experimental (min/max to min_of/max_of), then graduate — first_over_time and duration expressions are the current graduates, start_timestamp the next candidate behind use-start-timestamps. The API is simultaneously being tightened, with the stats parameter deprecated ahead of rejection in the next major and credential forwarding across redirects already removed in 3.13. Service discovery keeps absorbing clouds as their APIs change, OCI added and a Hetzner label dropped in the same release.

◆ Prediction

A 3.14.0 final should follow the release candidate within weeks, carrying the duration-expression and first_over_time promotions with it.

Redis stopped writing about the AI memory tier and shipped a feature store.

◆ Current state

The visible feed is dominated by developer-education content - RAG chunking, speculative decoding, prefill versus decode, agents versus workflows - all arguing that Redis is where AI systems keep state. Underneath it sit the actual releases: Redis Feature Form, an enterprise feature store for production ML; persistent real-time memory for Google ADK agents; Redis Insight 3.2.0 connecting to Azure Managed Redis with Entra ID; native OpenTelemetry metrics in the client libraries; and client-side geographic failover for Active-Active. Nothing in this feed has moved since late April.

◆ Where it's heading

The content-first pattern is resolving into products. Feature Form is the turn: Redis enters a category with established vendors instead of remaining the infrastructure those vendors build on, which moves it from the caching line of a budget to the ML platform line. The supporting releases are about fitting existing enterprise environments rather than adding database capability - Entra ID for Microsoft directory shops, OpenTelemetry for teams already standardised on it.

◆ Prediction

Expect more named products in the AI stack rather than more explainers, with the agent-memory work the likeliest thing to be packaged next given how much of the content already argues for it. The three-month gap in this feed leaves the timing unclear.
