What is CHNOSZ?

A geochemistry thermodynamics engine that changed its units and its database schema in one release.

CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.

What is plume?

A niche R package for author bylines that keeps sanding down the edges of academic metadata.

plume builds author lists, affiliations, and CRediT contribution statements for R Markdown and Quarto documents. After a long stretch of small correctness releases through 2024, 0.3.0 in September 2025 broke the pattern with the largest feature batch since 0.2.0 — plain-function constructors, configurable symbols, and finer control over initials. The package covers one narrow job and covers it thoroughly.

CHNOSZ vs plume: editorial side-by-side

C
CHNOSZ
INFRA · APIS
0.0

A geochemistry thermodynamics engine that changed its units and its database schema in one release.

◆ Current state

CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.

◆ Where it's heading

2.0.0 was the structural break — Joules replacing calories as the default output of subcrt(), a required E_units column, a new model column, and the removal of a legacy scaling convention for heat-capacity coefficients. Everything since has built on that settled foundation rather than disturbing it. The direction of the last two releases is toward coverage of specific mineral systems, rare earths and uranyl among them, and toward making the package approachable, which suggests a maintainer courting new users rather than reworking the engine.

◆ Prediction

The next release most likely continues OBIGT curation for particular element systems plus vignette work; the highlights format gives no signal of engine-level changes pending.

0.0

A niche R package for author bylines that keeps sanding down the edges of academic metadata.

◆ Current state

plume builds author lists, affiliations, and CRediT contribution statements for R Markdown and Quarto documents. After a long stretch of small correctness releases through 2024, 0.3.0 in September 2025 broke the pattern with the largest feature batch since 0.2.0 — plain-function constructors, configurable symbols, and finer control over initials. The package covers one narrow job and covers it thoroughly.

◆ Where it's heading

The release history reads as a slow campaign against edge cases in a domain full of them: authors with no roles, non-cased scripts, duplicate family names, YAML headers containing comments the writer must not destroy. Over 2024 nearly every release was a fix or a small parameter refinement, with PlumeQuarto steadily catching up to Quarto's own author schema. 0.3.0 shows the maintainer beginning to smooth the API itself rather than only its behaviour — aliases for the R6 constructors, deprecations moved to where they belong.

◆ Prediction

Expect continued tracking of Quarto's author-metadata schema as it changes upstream, and more API smoothing of the kind 0.3.0 started; the ORCID icon regression caused by Quarto's path resolution suggests upstream churn will keep setting the agenda.
