What is exametrika?

A test-theory package that grew into a graphical-model toolkit, now spending its releases paying down the API debt that growth created.

exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.

What is Windsurf?

Windsurf's own feature list has thinned out; what ships now is Devin arriving one surface at a time.

Across this stretch of the changelog, nearly every substantive release is a Devin capability landing inside the editor: the agent itself, Devin for Terminal, then Devin Review and Quick Review extended to all users on their existing subscription. The IDE-native work that remains is packaging around that — an agent inbox, session sorting, Windows stability. The other recurring release type is simply making new frontier models selectable.

◆ Current state

exametrika is an R psychometrics package covering IRT, latent class/rank analysis, and biclustering, and it has been shipping features at an unusual clip for a CRAN package. The last two releases stopped adding capability and turned inward: 1.14.0 fixed a documented-but-never-implemented graphical-parameter passthrough, and 1.15.0 landed a full-codebase audit that corrected bugs which silently produced wrong results on missing data and 0-indexed polytomous codes. Argument names, orders, and defaults are now unified across the model functions, with every old name kept working behind a deprecation warning.

◆ Where it's heading

The arc runs from feature sprawl to consolidation. Through 1.9.0-1.13.0 the package added polytomous biclustering plots, nominal and ordinal IRM samplers, a C++ Gibbs core, and Graphical Lasso; the cost was inconsistent interfaces and correctness bugs that only surfaced under audit. The maintainer is also visibly optimizing for two external gatekeepers — CRAN's 10-minute check budget in 1.13.1, an R Journal reviewer in 1.14.0 — which suggests the package is being groomed for formal publication rather than just iterated on.

◆ Prediction

Expect the next release to continue the deprecation cleanup started in 1.15.0, likely retiring some of the old function names that have carried warnings since 1.7.0, with new modelling work paused until the R Journal submission clears.

◆ Current state

The IDE-native work that remains is packaging around that — an agent inbox, session sorting, Windows stability. The other recurring release type is simply making new frontier models selectable.

◆ Where it's heading

Windsurf is converging on being the interface layer for Cognition's agent rather than an independently evolving editor. The pattern in these entries is consistent: a Devin surface ships, then it is unbundled from a separate purchase and folded into the existing subscription. Meanwhile the editor's own release notes are increasingly bug fixes and model availability notices, which is what a front end looks like when the differentiation has moved behind it.

◆ Prediction

Expect the next notable releases to be further Devin surfaces reaching general availability on the existing subscription rather than new editor features, and continued same-week model-availability notices. The entries give no signal on whether the JetBrains plugin gets the same Devin surfaces.
