Abstract

This document compiles the release notes for multiple Early Access Program (EAP) builds of RustRover 2026.1 (EAP 1 through EAP 7). The updates primarily focus on stabilizing the IDE through the resolution of various bugs across core subsystems, including build and run configurations, code insight, debugging, and UI responsiveness. Key addressed issues involve the integration of cargo-nextest, resolution of false-positive compiler errors (E0382, E0415, E0599), and rectification of configuration parsing errors affecting cross-platform (Windows) path handling.

Release Summary: RustRover 2026.1 EAP Build Cycle

• Build & Run Enhancements:
  • Fixed failure in re-running failed tests for cargo-nextest (RUST-19798).
  • Resolved regression where Install binary crate actions failed when non-cargo configurations were active (RUST-19637).
  • Corrected automatic generation of test run configurations, ensuring proper test name placement (RUST-19638).
  • Implemented support for debugging cargo-nextest run configurations (RUST-19507).
• Code Insight & Inspection Fixes:
  • Resolved multiple false-positive diagnostics, including E0382 (use of moved value), E0415 (duplicate identifiers in parameter lists), E0425 (macro expansion issues), and E0599 (missing abs method for i32) (RUST-13759, RUST-19062, RUST-19158, RUST-19113).
  • Fixed failure in "Go to Declaration" for include! macros involving generated sources in OUT_DIR (RUST-19390).
• Environment & Tooling Stability:
  • Resolved path and quotation mark parsing errors in run configurations specifically on Windows environments (RUST-17825, RUST-19566).
  • Fixed debugger failure to step into the standard library on Nightly toolchains (RUST-19305).
  • Corrected IDE behavior regarding "Sync Cargo Changes" prompts in empty lib.rs files (RUST-18791).
• UI & UX Improvements:
  • Added visibility specification options for modules within the "New Rust file" dialog (RUST-12697).
  • Fixed UI jitter/jumping during auto-format on save (RUST-17578).
  • Eliminated duplicate context menu items during split-mode editing (RUST-19608).
  • Resolved EDT (Event Dispatch Thread) busy exceptions during project setting updates (RUST-19012).

Recommended Review Group: This topic should be reviewed by the IDE Platform Engineering Team and the Rust Tooling QA Group. These stakeholders are responsible for compiler-integrated diagnostics, run-time environment stability, and maintaining the feature parity of the IntelliJ-based Rust ecosystem.
