The AI assistant is now something the IDE has to clean up after.

◆Current state
RStudio's release feed is raw commit subjects off release branches rather than curated notes — several entries are a single truncated line, and one is just a branch update. The substantive commits in this window cluster around Posit Assistant: gating .positai and .claude ignore-file augmentation on whether those directories actually exist, and adding SHA-256 integrity verification for Posit Assistant package downloads.
◆Where it's heading
The assistant is enabled by default and is starting to leave marks on projects that never asked for it — the ignore-file fix exists because .positai and .claude were being written into .Rbuildignore, .gitignore and svn:ignore in every project regardless of use. That is the characteristic second phase of shipping an AI feature: not building it, but containing its side effects. Alongside that, the notebook and console output work continues, with a data.table auto-print regression traced back to a print override change several releases earlier.
◆Prediction
Expect further Posit Assistant containment and supply-chain work, since two of the six visible commits are already about its filesystem footprint and download integrity rather than its capabilities.

    RStudio suppresses invisible data.table auto-print in notebooks

    Fixes data.table objects returned invisibly from a := update being auto-printed in notebook chunks — a regression from an earlier print override change, where signalling suppression by returning NULL fell through to data.table's own stateful print method. The backport ships without its Playwright regression test because the branch lacks the test infrastructure.

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

    Stops .positai and .claude from being written into .Rbuildignore, .gitignore and svn:ignore in projects that never used AI features, gating the augmentation on directory existence and watching the project file monitor to catch them appearing mid-session. The clearest example of the assistant's default-on footprint needing to be reined in.

    RStudio verifies Posit Assistant downloads with SHA-256

    Adds SHA-256 integrity verification for Posit Assistant package downloads. A supply-chain control on a component the IDE fetches at runtime, arriving as the assistant becomes a default-enabled part of the product.
