Integrated development environment for R and Python data science

posit.co/products/open-source/rstudio ↗

RStudio's release feed is single-commit build stamps, and the AI assistant work shows only in the fixes.

r-ideposit-assistantrelease-branchesbackportsnotebooks
◆Current state
The feed publishes one tag per merged commit against named release branches, so most entries carry a single line of body text or just a co-author credit. What detail exists points at two areas: Posit Assistant integration — SHA-256 verification for its package downloads, and a fix stopping .positai and .claude directories being written into .Rbuildignore, .gitignore and svn:ignore in projects that never used AI features — and notebook correctness, including a data.table auto-print regression backported to the golden-wattle branch.
◆Where it's heading
Development is spread across several concurrently maintained release branches with fixes backported between them, which is why the version numbers jump around rather than progressing linearly. The AI assistant is enabled by default and its rough edges are being sanded down one at a time; the ignore-file fix in particular reads as a response to the assistant touching projects that had not opted in. Nothing here signals a shift in direction — this is a mature IDE on a maintenance cadence.
◆Prediction
Expect further Posit Assistant refinements to arrive as isolated backported fixes rather than announced features, following the pattern of the last four months. Substantive release detail will continue to live in the NEWS files rather than these tags.

    RStudio 2026.06.0 drops a throwaway thread on Windows exits

    Reads child process exit output on Windows without spawning a throwaway thread. An internal efficiency change with no effect a user would notice.

    RStudio suppresses invisible data.table auto-print in notebooks

    Fixes a regression where a data.table returned invisibly from a := update was auto-printed in notebook chunks, by returning early on the suppression signal instead of falling through to data.table's own print method. Restores consistency with console and knitr behaviour for a widely used package.

    RStudio only adds .positai/.claude ignores when they exist

    Stops .positai and .claude being added to ignore files in projects that never used AI features, gating the change on directory existence and watching the project file monitor to add them mid-session instead. A direct correction to the assistant being on by default.

    RStudio verifies Posit Assistant downloads with SHA-256

    Adds SHA-256 integrity verification to Posit Assistant package downloads. Supply-chain hardening for a component that now ships enabled by default.
