What is CrowdSec?

CrowdSec's WAF is growing a bot-detection challenge — log analysis meets active interception.

The feed carries only release candidates, roughly one every two to three months, and the WAF has been the centre of gravity across all of them: OpenAPI schema validation, request body size limits, arbitrary AND/OR mixing in rule conditions, more Coraza transformations exposed, RE2 enabled by default on Linux. The 1.8.0 candidate breaks that pattern by adding challenge-and-fingerprint bot detection, serving an interstitial page and evaluating the result against configured rules. The same candidate adds a dedicated Kubernetes datasource that reads logs from the apiserver directly, and HTTP helpers so parsers and scenarios can query external services. Two earlier candidates in the window are pure refactoring with no user-visible change.

What is Strimzi?

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

CrowdSec's WAF is growing a bot-detection challenge — log analysis meets active interception.

◆ Current state

The feed carries only release candidates, roughly one every two to three months, and the WAF has been the centre of gravity across all of them: OpenAPI schema validation, request body size limits, arbitrary AND/OR mixing in rule conditions, more Coraza transformations exposed, RE2 enabled by default on Linux. The 1.8.0 candidate breaks that pattern by adding challenge-and-fingerprint bot detection, serving an interstitial page and evaluating the result against configured rules. The same candidate adds a dedicated Kubernetes datasource that reads logs from the apiserver directly, and HTTP helpers so parsers and scenarios can query external services. Two earlier candidates in the window are pure refactoring with no user-visible change.

◆ Where it's heading

CrowdSec started as a log-reading detection engine that handed decisions to external bouncers, and the WAF work has been steadily moving it into the request path. Bot detection completes that move: the product now generates its own signal by interrogating the client rather than only inferring from logs. The Kubernetes datasource and the expression-language HTTP helpers point the same way — fewer intermediaries between CrowdSec and both the telemetry and the enforcement point.

◆ Prediction

Expect the fingerprinting rules to become a shared, community-curated resource in the same way detection scenarios already are, since that is the pattern this project applies to every new signal it collects.

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

◆ Current state

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

◆ Where it's heading

Post-1.0 Strimzi is spending its cycles on how the operator manages Kubernetes resources rather than on new Kafka surface. ServerSideApplyPhase1 has gone alpha to GA and is now always on, and 1.2.0 changes install-time defaults toward Restricted Pod Security Standard security contexts and volume-mounted Service Account tokens. A second candidate carrying one logging fix says the cycle is converging rather than still absorbing change — the CRD v1-only requirement from 1.0.0 remains the loudest thing in every release body.

◆ Prediction

Expect 1.2.0 final shortly with no further candidates, and the next cycle to advance one of the open feature gates — UseBackgroundPodDeletion is the likeliest to move from alpha to beta.
