What is Buildkite?
Buildkite keeps converting hand-rolled agent workarounds into first-class CI primitives.
Buildkite is shipping on two fronts. For agents, the MCP server gained list_tests for suite-wide reliability and duration metrics, and the Test Engine API returns the same aggregates behind a version header. For humans, a native checkout block moved sparse clones, shallow depth and skip-checkout out of plugins and into pipeline YAML, agents can ship job logs to an OpenTelemetry collector, and an organization-wide banner now says when GitHub API rate limits - not Buildkite - are holding up pull request status.
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.

Buildkite keeps converting hand-rolled agent workarounds into first-class CI primitives.
◆ Current state
Buildkite is shipping on two fronts. For agents, the MCP server gained list_tests for suite-wide reliability and duration metrics, and the Test Engine API returns the same aggregates behind a version header. For humans, a native checkout block moved sparse clones, shallow depth and skip-checkout out of plugins and into pipeline YAML, agents can ship job logs to an OpenTelemetry collector, and an organization-wide banner now says when GitHub API rate limits - not Buildkite - are holding up pull request status.
◆ Where it's heading
Buildkite is arguing that CI should be forge-independent, and backing it with coverage: GitHub, GitLab, Bitbucket, and now Cursor's Origin, where it shipped as a launch partner on day one. The agent-facing work follows one pattern - remove the workaround automation used to need, so aggregated test metrics replace assembling individual runs and a rate-limit banner replaces guessing why a status never arrived. Each release turns a behavior teams hand-rolled into a supported primitive.
◆ Prediction
The read side of the MCP server is now largely covered, so expect write-side tools next - retrying jobs, unblocking builds, editing pipelines from an agent - following the pattern the REST expansion established.
CHNOSZ
0.0INFRA · APIS
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.
