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 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.

CHNOSZ vs NGINX: editorial side-by-side

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.

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.
