Added release note `notes/New Features in v0.5.8.md`. +2. **expr-eval Replacement**: `expr-eval` had a high-severity prototype pollution vulnerability (GHSA-8gw3-rxh4-v6jx, GHSA-jc85-fpwf-qm7x) with no fix available. Replaced with `src/lib/evaluator.ts` — a ~150-line recursive descent parser supporting `+`, `-`, `*`, `/`, `%`, `^`, parentheses, unary operators, and variable scope resolution. Includes 26 unit tests covering arithmetic, precedence, variables, and error cases. Removed `expr-eval` from `package.json`. +3. **TypeScript Strict Mode**: Enabled `"strict": true` in `tsconfig.app.json`. Codebase was already compatible — zero new type errors. +4. **Unused Dependency Removal**: Removed `@tauri-apps/plugin-fs` and `@tauri-apps/plugin-shell` from `package.json` — these npm packages were not imported anywhere in the JS/TS codebase and had no corresponding Rust plugin in `Cargo.toml`. Note: `@emnapi/core` and `@emnapi/runtime` were initially removed but restored because they are required in the lockfile as transitive WASM fallback dependencies for Linux/Windows CI runners. +5. **API Type Safety**: Changed `onEvent` from `(payload: any) => void` to generic `(name, callback: (payload: T) => void)`, removing the eslint-disable comment. +6. **Coverage Thresholds**: Added minimum coverage guardrails to `vite.config.ts` (statements 65%, branches 50%, functions 55%, lines 65%). + +**Files changed:** `package.json`, `package-lock.json`, `src-tauri/Cargo.toml`, `src-tauri/Cargo.lock`, `src-tauri/tauri.conf.json`, `tsconfig.app.json`, `vite.config.ts`, `src/api.ts`, `src/lib/evaluator.ts` [NEW], `src/lib/evaluator.test.ts` [NEW], `src/lib/editor/MathEvaluator.ts`, `src/lib/editor/VariableScope.ts`, `src/hooks/useVariables.ts`, `notes/New Features in v0.5.8.md` [NEW], `CHANGELOG.md`, `AUDIT_LOG.md`. + +--- + ## 2026-06-29 (CI Signing Key Sanitization Fix) **Change:** fix(ci): sanitize `TAURI_SIGNING_PRIVATE_KEY` before `tauri build` to strip trailing terminal prompt artifacts (`%`) or URL encoding diff --git a/CHANGELOG.md b/CHANGELOG.md index b090b8b..2d16018 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -7,6 +7,22 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 ## [Unreleased] +## [v0.5.8] - 2026-06-29 + +### Added +- **Custom Arithmetic Evaluator**: Replaced `expr-eval` (high-severity prototype pollution vulnerability, no fix available) with a new custom recursive-descent arithmetic evaluator supporting `+`, `-`, `*`, `/`, `%`, `^`, parentheses, unary operators, and variable scope resolution.
