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 ggVennDiagram?

A Venn diagram package whose public release notes say almost nothing — including about its copyright cleanup.

ggVennDiagram draws Venn diagrams as ggplot2 objects. The visible release feed is thin and irregular: three entries between 2021 and 2024, two of which contain nothing but a pointer to NEWS. Only the most recent, V1.5, describes actual changes, and both of them are legal housekeeping rather than features.

CHNOSZ vs ggVennDiagram: editorial side-by-side

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 Venn diagram package whose public release notes say almost nothing — including about its copyright cleanup.

◆ Current state

ggVennDiagram draws Venn diagrams as ggplot2 objects. The visible release feed is thin and irregular: three entries between 2021 and 2024, two of which contain nothing but a pointer to NEWS. Only the most recent, V1.5, describes actual changes, and both of them are legal housekeeping rather than features.

◆ Where it's heading

What can be read here is not a feature direction but a tidying of provenance. V1.5 removed code copied from yulab.utils and made the package comply with the copyright terms of the venn package it draws on, with the yulab.utils maintainer appearing as a first-time contributor to do it. Everything else in the window defers to a changelog kept outside the feed, so the direction of the package itself is not readable from these entries.

◆ Prediction

No reliable prediction is available from this feed — the release notes are pointers rather than descriptions, and the visible entries skip whole version ranges.
