0.9.2 - 2026-09-10

Release Notes

This release reduces false positives in package code and fixes a crash when
reading serialized package data.

Fixed

• Keep subset results unknown when the receiver has no known subsetting
  contract. This avoids a false condition-length warning in rstan, and
  likewise keeps union receivers such as
  if (p) c("a", "b") else c("a", "b", "c") from carrying their
  source lengths past a [ subset into a false condition-length
  warning.
• Read cyclic serialized objects without a stack overflow, including the
  package data used by workflowsets.
• Keep .data opaque in data-masked calls such as aes() when no usable
  data argument is available. Calls with known data frames still report
  missing columns (#383).
• Correct mirai::status() to accept .compute and return a list, so $
  access no longer produces a false RY061 error (#382).
• Keep class information unknown for opaque stub results without class
  metadata. This avoids false RY092 diagnostics (#341).
• Skip non-function bindings when looking for outward functions at bare
  call heads. Package functions take precedence over dataset names (#384).
• Keep later assignments from invalidating forwarded defaults at earlier
  direct calls (#342).
• Widen default-derived parameter types in branches that reject their
  inferred mode, avoiding false $ errors in those branches (#343).
• Accept scalar character, raw, and complex conditions that R can coerce
  to logical. Known invalid literals still produce RY001. Multi-value
  conditions are newly visible as RY001 warnings in default output:
  numeric conditions previously carried only the default-off RY003
  nudge, and multi-element logical loop conditions were not reported
  (#373). Review baselines and --error-on-warning runs for new
  findings.
• Report files whose parser cannot be initialized instead of panicking the
  whole check, and fall back to serial indexing in the language server when
  its parse pool cannot be built.

Changed

• Raise the default serialized-data cap from 2 MiB to 16 MiB. Packages such
  as gt can resolve their internal data names without custom configuration.
  Larger files still produce a degraded-scope notice (#378).
• Reduce binary size with symbol stripping, full LTO, and compressed
  embedded stubs. Load package stubs when needed (#340).
• Speed up workspace indexing and project checks with bounded parallel
  processing and cached package discovery (#340).
• Hash checker-internal identifier maps with FxHash instead of SipHash.
  Scope's public collections (bindings, parameter_bindings,
  function_aliases, and siblings) are now FxMap/FxSet rather than
  HashMap/HashSet; a source-level change for library consumers (#340).
• Clarify RY001 and RY070 messages. Baselines match message text, so
  previously accepted findings can reappear after upgrading. Review them
  before regenerating the entries you still accept.

Editors and maintenance

• Align the core and VS Code/Positron extension at 0.9.2. The extension uses
  a smaller production bundle and reuses successful binary-version checks
  during the same editor session; see its changelog.
• Use scholzmx.ry-checker for the VS Code Marketplace listing and keep
  scholzmx.ry for Open VSX. Prepare ry-lsp as the Zed gallery identity.
• Update R setup, Pages deployment, and workflow security Actions.
