What is Distributions.jl?

Julia's distribution library grinds forward one distribution at a time

Distributions.jl ships small, frequent releases against a large and settled API surface. Recent work splits between correctness fixes to individual distributions (LogitNormal formulas, Semicircle quantiles, Truncated Chernoff), incremental fitting support such as sufficient statistics and MLE for Chi and Chisq, and infrastructure moves like more consistent error types and global sparsity tracing through constructors.

What is Rho?

Rho's release machinery finally produced a stable build — and it shipped no new product.

Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains almost entirely release engineering. The one substantive entry, 0.4.0-dev.39, described capability-based model routing across providers and durable project-scoped agent conversations with per-file Apply/Undo. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.

Distributions.jl vs Rho: editorial side-by-side

D2.5

Julia's distribution library grinds forward one distribution at a time

◆ Current state

Distributions.jl ships small, frequent releases against a large and settled API surface. Recent work splits between correctness fixes to individual distributions (LogitNormal formulas, Semicircle quantiles, Truncated Chernoff), incremental fitting support such as sufficient statistics and MLE for Chi and Chisq, and infrastructure moves like more consistent error types and global sparsity tracing through constructors.

◆ Where it's heading

The arc is consolidation rather than expansion: dependencies are being pruned and internals made more predictable so the package composes cleanly with the rest of the Julia numerical stack. Support for sparsity tracing and looser MvNormal type aliases both point at making the library easier to drive from automatic-differentiation and optimization code.

◆ Prediction

Expect the same cadence of per-distribution fixes and fitting-method additions, with continued work on making constructors transparent to tracing and AD tooling. Nothing in these entries signals a major version or API break.

Rho's release machinery finally produced a stable build — and it shipped no new product.

◆ Current state

Rho is an R IDE that has just moved from an all-prerelease train to a stable 0.4.0, and its public feed remains almost entirely release engineering. The one substantive entry, 0.4.0-dev.39, described capability-based model routing across providers and durable project-scoped agent conversations with per-file Apply/Undo. The releases since then have been distribution work: a signed automatic updater shared across Windows, macOS and Linux, then the stable build that packages it.

◆ Where it's heading

The project is building an agentic R IDE but publishing like a regulated release process: signed evidence, checksums bound to exact commits, and limitations named out loud rather than buried. That discipline has now paid off in the only way it could — 0.4.0 stable ships a Windows installer, a notarized macOS disk image and a Linux AppImage that can all update themselves, with failed verification preserving the running version. The feed's long-standing pattern of dev.NN builds with no final has broken; feature work and shipping work were on separate tracks, and the shipping track arrived first.

◆ Prediction

With distribution solved, the next entry that matters is the first one describing product capability again rather than packaging. The unresolved item these releases name themselves is Windows trust: the installer is still signed with a SignPath Free Trial self-signed certificate that SmartScreen may warn on.
