What is funcharts?

One paper, one release: the functional control chart package ships methods as they get published.

funcharts implements control charts for functional data — statistical process control where each observation is a curve rather than a number. Its release cadence maps one-to-one onto its authors' publication record: 1.4.0 delivered the robust multivariate framework from Capezza et al. (2022), 1.7.0 the adaptive chart from Centofanti et al. (2025) as it was accepted at Technometrics. Each release adds Phase I and Phase II functions for one named method.

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.

0.0

One paper, one release: the functional control chart package ships methods as they get published.

◆ Current state

funcharts implements control charts for functional data — statistical process control where each observation is a curve rather than a number. Its release cadence maps one-to-one onto its authors' publication record: 1.4.0 delivered the robust multivariate framework from Capezza et al. (2022), 1.7.0 the adaptive chart from Centofanti et al. (2025) as it was accepted at Technometrics. Each release adds Phase I and Phase II functions for one named method.

◆ Where it's heading

The early releases were about the package as software — vectorised tensor products, precomputed B-spline inner products, faster cross-validation — and about removing assumptions, most consequentially the assumption that functional data is represented in a B-spline basis. Since 1.4.0 the software work has stopped and the package has become a delivery vehicle for the research group's methods. Robustness came first, adaptivity second, both arriving with the paper rather than ahead of it.

◆ Prediction

The next release will most likely implement whatever this group publishes next, following the same Phase I / Phase II function pairing; nothing in the feed suggests infrastructure work resuming.

2.5

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.
