Cribl vs Grafana Loki: at a glance
What is Cribl?
Cribl Stream 4.20.3 takes its Terraform provider out of preview and renames its AI editor.
Cribl Stream 4.20.0 landed in September, followed by patches fixing Sentinel OAuth failures, worker memory growth and a JSON Event Breaker bug that silently dropped records. 4.20.3 moved the Terraform provider out of preview and renamed Copilot Editor to Pipeline Builder. Early-access notes for 4.21.0 appeared on November 10 and lead with rollback and deprecation notices that need action, without detail yet.
What is Grafana Loki?
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

◆ Current state
Cribl Stream 4.20.0 landed in September, followed by patches fixing Sentinel OAuth failures, worker memory growth and a JSON Event Breaker bug that silently dropped records. 4.20.3 moved the Terraform provider out of preview and renamed Copilot Editor to Pipeline Builder. Early-access notes for 4.21.0 appeared on November 10 and lead with rollback and deprecation notices that need action, without detail yet.
◆ Where it's heading
Minors land about every two months (May, July, September), each followed by two or three critical patches, with recent fixes targeting silent failures in ingestion and authentication. 4.20.3 points the other way too: configuration-as-code is maturing through Terraform even after the TypeScript and Go SDKs were discontinued, and the AI features are being repackaged under new names and tiers.
◆ Prediction
A 4.21.0 minor around November fits the two-month cadence; the entries don't show its content. Terraform looks set to be the supported infrastructure-as-code path.
Grafana Loki
6.3ANALYTICS
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
◆ Current state
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.
◆ Where it's heading
Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.
◆ Prediction
Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.
