What is DNSControl?

DNSControl v5 is feature-frozen with a ship date, and rc9 is pure provider cleanup

DNSControl has locked v5.0.0 to bugfixes only with a stated ship date of 25 August 2026. rc9 carries no new capability: punycode decoding before IDNA validation in ALIDNS, a SVCB fix in POWERDNS, NAPTR and trailing-dot fixes in DYNU, a dnssort edge case, and internal refactors replacing pkg/diff and standardising on models.Records. The release notes read as a call for provider testing more than an announcement.

What is sps?

sps keeps sanding down sequential Poisson sampling rather than adding to it.

The package implements sequential Poisson sampling for survey design, covering inclusion probabilities, proportional allocation, replicate weights, and take-all strata. Recent releases are small and tightly scoped: a divisor method helper, an iterator that draws a sample one unit at a time, automatic selection of the replicate-weight parameter, and repeated performance work on inclusion probability calculation.

DNSControl v5 is feature-frozen with a ship date, and rc9 is pure provider cleanup

◆ Current state

DNSControl has locked v5.0.0 to bugfixes only with a stated ship date of 25 August 2026. rc9 carries no new capability: punycode decoding before IDNA validation in ALIDNS, a SVCB fix in POWERDNS, NAPTR and trailing-dot fixes in DYNU, a dnssort edge case, and internal refactors replacing pkg/diff and standardising on models.Records. The release notes read as a call for provider testing more than an announcement.

◆ Where it's heading

The v5 arc has run its course in public: rc1 laid out the dnsv2.RDATA refactor, rc3 finished converting every provider to it, rc4 completed the move to the Codeberg-hosted miekg/dns, and rc8 declared feature completeness. What is left is per-provider correctness on record types that only a handful of users exercise, which is why the maintainer is publishing a list of which providers most need testing rather than shipping.

◆ Prediction

Expect one or two more release candidates of provider fixes before the 25 August date, with the risk concentrated in providers nobody volunteers to test - the notes already flag PACKETFRAME as unmaintained and EXOSCALE as not supporting PTR.

sps keeps sanding down sequential Poisson sampling rather than adding to it.

◆ Current state

The package implements sequential Poisson sampling for survey design, covering inclusion probabilities, proportional allocation, replicate weights, and take-all strata. Recent releases are small and tightly scoped: a divisor method helper, an iterator that draws a sample one unit at a time, automatic selection of the replicate-weight parameter, and repeated performance work on inclusion probability calculation.

◆ Where it's heading

Development is consolidation rather than expansion. Most releases either speed up an existing routine or remove a decision the user previously had to make by hand, such as picking the smallest parameter that keeps replicate weights non-negative. Documentation and tooling get comparable attention to the algorithms, with a dedicated vignette on inclusion probabilities and a recent switch of test and documentation infrastructure. The API surface has been essentially stable across the window.

◆ Prediction

Expect continued small ergonomic and performance releases against the existing function set rather than new sampling designs, which is the pattern every release in this window follows.
