nzilbb.vowels vs Volatility: at a glance
What is nzilbb.vowels?
A vowel-analysis package trimming dependencies after an email address got it archived.
nzilbb.vowels supports sociophonetic vowel analysis — principal component analysis over vowel measurements, Procrustes comparison of loadings, and the plotting that goes with them. Three releases are visible, all in the 0.4.x line and all small. The substantive thread is dependency removal: vegan and gghalves have both been dropped in favour of code the package controls.
What is Volatility?
Volatility 3 caught up with Volatility 2, then started reorganising itself.
The 2.26.0 release was explicitly aimed at functional parity with the archived Volatility 2, landing around twenty plugins at once across Linux, macOS and Windows. Since then the work has shifted from filling gaps to structuring what exists: malware-specific plugins moved under a malware namespace with the old names deprecated, an arrow/parquet output renderer added, volshell given breakpoints, and per-release additions like sockscan, process_spoofing, pebmasquerade and etwpatch.

A vowel-analysis package trimming dependencies after an email address got it archived.
◆ Current state
nzilbb.vowels supports sociophonetic vowel analysis — principal component analysis over vowel measurements, Procrustes comparison of loadings, and the plotting that goes with them. Three releases are visible, all in the 0.4.x line and all small. The substantive thread is dependency removal: vegan and gghalves have both been dropped in favour of code the package controls.
◆ Where it's heading
The package is reducing what it relies on, and paying for it in small interface breaks — plot_correlation_counts() lost its half_violin argument and gained a points argument in the same move. The 0.4.2 notes also record that version 0.4.1 was archived by CRAN because the maintainer's email had become unreliable, prompting a switch to an institutional address. That is administrative rather than technical, but it explains why three closely spaced patches exist at all.
◆ Prediction
With the two external plotting and ordination dependencies gone and the maintainer address stabilised, the visible pressure that produced these releases is resolved. Nothing in the entries indicates what comes next, and the history is too short to read a feature direction from.

Volatility 3 caught up with Volatility 2, then started reorganising itself.
◆ Current state
The 2.26.0 release was explicitly aimed at functional parity with the archived Volatility 2, landing around twenty plugins at once across Linux, macOS and Windows. Since then the work has shifted from filling gaps to structuring what exists: malware-specific plugins moved under a malware namespace with the old names deprecated, an arrow/parquet output renderer added, volshell given breakpoints, and per-release additions like sockscan, process_spoofing, pebmasquerade and etwpatch.
◆ Where it's heading
Two things are happening at once. The plugin catalogue keeps growing on the Linux side in particular — tracing, kallsyms, ftrace, VMA scanning, smearing protection — reflecting where memory forensics currently has the least coverage. And the framework is being made into something other tools consume: structured output formats, a shipped Windows executable, a namespaced plugin taxonomy with a year-long deprecation window. The project is treating plugin names as an interface it owes users stability on.
◆ Prediction
Expect the malware namespace migration to complete as the deprecated names age out, and the Linux plugin surface to keep taking the bulk of new additions, with output-format work continuing to open the framework to automated pipelines.
