What is NGINX?

nginx returns to feature work with PROXY v2 upstream writes, and quietly adds JSON to core.

1.31.4 is the first mainline release in months that is not primarily a CVE response. It adds PROXY protocol version 2 write support for stream upstreams, special-cases the Host header for HTTP and gRPC upstreams, and tightens QUIC flow control on RESET_STREAM final sizes. Underneath those, core gained data model and JSON serialization libraries that nothing in this release consumes.

What is robscale?

A robust-statistics package rewrote its estimators in SIMD C++ and went to CRAN in two weeks.

robscale computes robust scale and location estimators, and its pitch is speed: 21 to 26 times faster than stats::mad, 37 times faster than stats::IQR on small samples, with comparable margins over robustbase for Qn and Sn. The March 2026 releases took it from a GitHub project to a CRAN package carrying eleven estimators, all with confidence intervals.

nginx returns to feature work with PROXY v2 upstream writes, and quietly adds JSON to core.

◆ Current state

1.31.4 is the first mainline release in months that is not primarily a CVE response. It adds PROXY protocol version 2 write support for stream upstreams, special-cases the Host header for HTTP and gRPC upstreams, and tightens QUIC flow control on RESET_STREAM final sizes. Underneath those, core gained data model and JSON serialization libraries that nothing in this release consumes.

◆ Where it's heading

The five preceding releases were security releases: three CVEs in July across both branches, an HTTP/2 and gRPC buffer overflow and an HTTP/3 use-after-free in June. Against that run, 1.31.4 reads as the project returning to feature work, with F5 contributors visible across the stream and upstream changes and four first-time contributors landing fixes. The JSON and data-model libraries are the item worth watching, since general serialization is not something a proxy needs for proxying.

◆ Prediction

Those libraries have no consumer in this release, so the plausible next move is a feature that uses them, such as structured status output or configuration, rather than another round of parser hardening.

A robust-statistics package rewrote its estimators in SIMD C++ and went to CRAN in two weeks.

◆ Current state

robscale computes robust scale and location estimators, and its pitch is speed: 21 to 26 times faster than stats::mad, 37 times faster than stats::IQR on small samples, with comparable margins over robustbase for Qn and Sn. The March 2026 releases took it from a GitHub project to a CRAN package carrying eleven estimators, all with confidence intervals.

◆ Where it's heading

Three releases in a fortnight walk a clear line: expand the public API, submit to CRAN, then tune. The 0.5.4 work is where that tuning shows, and it is unusually specific about hardware, raising sorting-network thresholds after benchmarking and dropping the AVX-512 path entirely in favour of a shorter AVX2-first dispatch chain. The build-fix lists are long, which is what a package fighting compiler and TBB variation across CRAN's platforms looks like.

◆ Prediction

The dispatch hierarchy has been simplified once already; further releases most likely continue narrowing the SIMD surface and hardening the configure step rather than adding estimators. A new estimator would be the surprise.
