DNSControl vs Split.io: at a glance
What is DNSControl?
DNSControl is rewriting its record internals in public, one release candidate at a time
DNSControl is mid-way through a v5 refactor being shipped as a visible candidate series — rc1 through rc4 in roughly two weeks, all of them explicitly promising zero user-facing change. The work replaces how DNS record fields are stored internally with a dnsv2.RDATA type, with legacy structs converted bidirectionally so existing providers keep working untouched. Two other threads run alongside: migrating the miekg/dns dependency from GitHub to Codeberg, now complete and no longer dual-imported, and removing old fields to cut memory use. The release notes read as direct appeals to users — naming nine providers nobody has tested and asking for volunteers, and inviting anyone to a monthly community call.
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.

DNSControl is rewriting its record internals in public, one release candidate at a time
◆ Current state
DNSControl is mid-way through a v5 refactor being shipped as a visible candidate series — rc1 through rc4 in roughly two weeks, all of them explicitly promising zero user-facing change. The work replaces how DNS record fields are stored internally with a dnsv2.RDATA type, with legacy structs converted bidirectionally so existing providers keep working untouched. Two other threads run alongside: migrating the miekg/dns dependency from GitHub to Codeberg, now complete and no longer dual-imported, and removing old fields to cut memory use. The release notes read as direct appeals to users — naming nine providers nobody has tested and asking for volunteers, and inviting anyone to a monthly community call.
◆ Where it's heading
The stated goals are about future velocity rather than present features: making new DNS record types faster to adopt and custom record types easier to implement. That is a bet that the bottleneck on supporting new record types was the internal representation, and it is being paid for with a long candidate series rather than a big-bang release. The provider conversion finished during this window — rc3 declares all providers converted with long-tail work remaining — so the refactor is past its riskiest stretch.
◆ Prediction
The maintainer states v5.x is on schedule to ship before September, and the untested-provider list is the visible blocker; expect further candidates focused on provider coverage rather than new goals.
Split.io
0.6INFRA · APIS
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.
