NGINX
nginx returns to feature work with PROXY v2 upstream writes, and quietly adds JSON to core.
A side-by-side editorial comparison of prospectr and Traefik — release velocity, themes, recent moves, and the top alternatives to consider.
prospectr spent its biggest release in years fixing spectra it had been quietly mangling.
prospectr provides the signal-processing layer for near-infrared and visible spectroscopy in R — Savitzky-Golay and gap-segment derivatives, standard normal variate, detrending, continuum removal, splice correction, plus calibration sampling algorithms like Kennard-Stone and DUPLEX and readers for ASD and BUCHI NIRCal instrument files. The May release is the substantial one: a long list of corrections to functions that were returning wrong or missing values rather than failing.
Traefik's 2.11 line spends August fixing the names it generates for Kubernetes resources.
The feed carries only the 2.11 maintenance line, and v2.11.55 is entirely bug fixes. Four of its seven items address generated-name collisions in the Kubernetes CRD provider: scoping Service names to their parent, an opt-in safe-naming mode, a guard against generated-name collisions, and a namespace restriction for default TLS resources. The remainder are a Gateway API router rule fix, a toggle to disable TLS options fallback, and dependency bumps.

The May release is the substantial one: a long list of corrections to functions that were returning wrong or missing values rather than failing.
The recent work is corrective rather than additive, and several items changed results silently before being caught. continuumRemoval() derived its convex-hull boundary offset from a fixed one-wavelength assumption that broke for fine-resolution spectra or non-nanometre units; cochranTest() passed an invalid argument name to prcomp() and produced incorrect principal component scores; readASD() silently dropped spectra in one branch of its text path. Two file readers were leaking connections. Alongside that runs a smaller thread of decoupling preprocessing steps from each other, most visibly detrend() gaining an snv argument so polynomial detrending can run without the SNV transform that Barnes et al. bundled with it.
The detrend() decoupling is the only recent addition and it fits a broader pipeline-composition direction, so similar separation of other bundled preprocessing steps is the plausible next move. The misspelled substraction argument now carries a deprecation warning, which schedules its removal for a future release.

The remainder are a Gateway API router rule fix, a toggle to disable TLS options fallback, and dependency bumps.
This branch is in pure maintenance, and the concentration is the signal: name generation in the CRD provider produced enough collisions to justify four separate changes and a new opt-in naming scheme inside a patch release. The two releases before it were CVE responses touching CONNECT tunnel handling and ReplacePathRegex path sanitization. Nothing here indicates feature work on this line.
Expect further 2.11 patches on the same footing, security fixes and Kubernetes provider corrections, with the safe-naming option a candidate to become the default once it has soaked.
