What is Split.io?

Split FME's March releases pull feature flags fully into the Harness DevOps platform.

Split.io now ships under the Harness Feature Management & Experimentation (FME) brand, and the substantive activity is captured in the rolled-up release-notes page rather than per-release entries. The March 2026 wave landed three real ships: Policy As Code (OPA) for FME Feature Flags, Feature Flag Archiving with RBAC and pre-archive checks, and the GA of FME steps in Harness pipelines covering full flag lifecycle management. The rest of the recent feed is scraper artifacts — page chrome captured as titles.

What is Retool?

Retool pushes self-hosted 4.0 to stable, laying RBAC and security groundwork for enterprise.

Retool's self-hosted line dominates this window: version 4.0 has reached the stable channel, carrying an automatic permissions-database migration that prepares the platform for Role-Based Access Control, with an upgrade FAQ to guide existing deployments. Around it, admins gain new controls — customizable Content Security Policy for apps — and a way to buy additional AI credit packs from organization settings. The cadence is dense and operational, centered on shipping and de-risking the 4.0 upgrade for self-hosters.

Split FME's March releases pull feature flags fully into the Harness DevOps platform.

◆ Current state

Split.io now ships under the Harness Feature Management & Experimentation (FME) brand, and the substantive activity is captured in the rolled-up release-notes page rather than per-release entries. The March 2026 wave landed three real ships: Policy As Code (OPA) for FME Feature Flags, Feature Flag Archiving with RBAC and pre-archive checks, and the GA of FME steps in Harness pipelines covering full flag lifecycle management. The rest of the recent feed is scraper artifacts — page chrome captured as titles.

◆ Where it's heading

FME is becoming a first-class part of the Harness DevOps surface rather than a standalone feature-flag tool. Pipeline-native flag operations, policy-as-code governance, and archiving as a managed lifecycle state all reflect a single direction: feature flags as a governed, audited, and pipeline-integrated component of the deployment system. The standalone Split UX is fading into Harness conventions.

◆ Prediction

Expect more Harness-platform conventions to land on FME — RBAC unification, environments and pipelines parity, OPA policy templates shipped out of the box, and observability tying flag changes back into deploy-failure/MTTR dashboards. Standalone-Split UX surfaces will likely be retired further.

10.0

Retool pushes self-hosted 4.0 to stable, laying RBAC and security groundwork for enterprise.

◆ Current state

Retool's self-hosted line dominates this window: version 4.0 has reached the stable channel, carrying an automatic permissions-database migration that prepares the platform for Role-Based Access Control, with an upgrade FAQ to guide existing deployments. Around it, admins gain new controls — customizable Content Security Policy for apps — and a way to buy additional AI credit packs from organization settings. The cadence is dense and operational, centered on shipping and de-risking the 4.0 upgrade for self-hosters.

◆ Where it's heading

Retool is advancing its self-hosted enterprise story — RBAC groundwork, CSP customization, and a managed upgrade path point to a focus on admin control and security posture for regulated, self-hosted deployments. Separately, AI usage is becoming a metered, separately-purchased resource. The platform is maturing self-hosted governance while turning AI into a billable line item.

◆ Prediction

Expect Role-Based Access Control to ship as a full feature on the back of the 4.0 permissions migration, plus continued 4.0 hardening — stable patches and more admin security controls.
