# Release notes

> VectorLint release history, mirrored from GitHub Releases.

These notes are mirrored from the [GitHub Releases](https://github.com/TRocket-Labs/vectorlint/releases) for the VectorLint package.

<Update label="2026-03-04" description="v2.5.0" tags={["features", "improvements"]}>
  ### Features

  * **User-facing `message` field**: LLM violations now include a dedicated `message` field — under 15 words, written directly to the user, with no rule references. This replaces `analysis` as the string shown in the terminal.
  * **`analysis` in JSON output**: The `analysis` field (internal model reasoning) is now included in `--output=json` violation objects alongside `message`, giving consumers access to both.

  ### Improvements

  * Directive guidance updated to explicitly distinguish `message` (user-facing) from `analysis` (internal reasoning not shown in UI)
</Update>

<Update label="2026-03-04" description="v2.4.0" tags={["features", "improvements"]}>
  ### Features

  * **PAT (Pay A Tax) Evaluation Technique**: New gate-check evaluation method using structured output for more reliable LLM-based assessments
  * **Amazon Bedrock Provider**: Run VectorLint against AWS-hosted models via the Amazon Bedrock LLM provider
  * **Vercel AI SDK Integration**: Unified LLM provider interface via Vercel AI SDK, enabling consistent behavior across all providers
  * **PAT Confidence Tuning**: Expose confidence thresholds via CLI to tune PAT filter sensitivity
  * **File-Type Context**: Evaluations now receive file-type context to improve rule applicability

  ### Improvements

  * Aligned CLI surfacing with PAT filters for consistent flag exposure
  * Tightened PAT confidence guidance for more predictable gate-check behavior
</Update>

<Update label="2026-02-11" description="v2.3.0">
  ### Features

  * **Zero-Config Mode**: Run VectorLint without any config file by adding a `VECTORLINT.md` to your
    project root
  * **User Instructions Support**: Global user instructions now run alongside all rules (previously
    fallback-only)
  * **Fix Suggestions**: New `fix` field in violation output provides drop-in replacement suggestions for
    both Check and Judge evaluations
  * **Init Command Enhancements**: New `--quick` flag creates only `VECTORLINT.md`, `--full` flag creates
    both config and user instruction files
  * **Improved Evaluation Instructions**: Centralized directive with structured Role/Task/Instructions
    format

  ### Improvements

  * Renamed internal terminology: "Style Guide" → "User Instructions" for clarity
  * Renamed evaluation types: `SubjectiveResult` → `JudgeResult`, `SemiObjectiveResult` → `CheckResult`
  * Removed redundant instruction sections from bundled preset prompts
  * Consolidated architectural documentation into CLAUDE.md

  **Full Changelog:** [https://github.com/TRocket-Labs/vectorlint/compare/v2.2.0...v2.3.0](https://github.com/TRocket-Labs/vectorlint/compare/v2.2.0...v2.3.0)
</Update>

<Update label="2026-01-02" description="v2.2.0" tags={["bugfixes", "features", "improvements"]}>
  ### Features

  * **Renamed Rule Types**: Rule types renamed for clarity — `semi-objective` → `check`, `subjective` → `judge`. Backward compatibility maintained via automatic mapping.
  * **Content Chunking**: Large documents are now automatically chunked for improved evaluation accuracy
  * **Bundled Rule Packs (Presets)**: Built-in rule packs now ship with VectorLint — no custom rules path required to get started
  * **Global Configuration**: New global config file for storing API keys and environment settings
  * **Init Command**: New `vectorlint init` command for easy project setup
  * **Token Usage Reporting**: CLI now displays input/output token counts after each evaluation
  * **Hidden Config Support**: Configuration can now be stored as a hidden file
  * **Disable Rules**: Support for disabling specific rules within a rule pack
  * **Improved Line Accuracy**: Better issue location with line numbering and fuzzy matching

  ### Improvements

  * Refactored help output for clearer CLI usage
  * Updated documentation to reflect optional rules path
  * Improved Anthropic provider configuration and type safety
  * Simplified evaluator token usage tracking

  ### Bug Fixes

  * Fix CLI to require explicit paths, preventing accidental directory scans
  * Fix path option description to indicate it's required

  **Full Changelog:** [https://github.com/TRocket-Labs/vectorlint/compare/v2.1.1...v2.2.0](https://github.com/TRocket-Labs/vectorlint/compare/v2.1.1...v2.2.0)
</Update>

<Update label="2025-12-12" description="v2.1.1" tags={["bugfixes"]}>
  ### Bug Fixes

  * **Fix Runtime Crash**: Resolved `Cannot find module` error in published package by inlining `package.json` version
  * Replaced relative runtime require with static import to prevent path resolution issues in `dist` artifacts
</Update>

<Update label="2025-12-12" description="v2.1.0" tags={["features"]}>
  ### Features

  * **Reviewdog Support**: Added `rdjson` (Reviewdog Diagnostic JSON Format) output capability
  * Enables automated code review comments and annotations in CI/CD pipelines
  * CLI now accepts `--output rdjson` flag

  **Full Changelog**: [v2.0.1...v2.1.0](https://github.com/TRocket-Labs/vectorlint/compare/v2.0.1...v2.1.0)
</Update>

<Update label="2025-12-09" description="v2.0.1" tags={["bugfixes", "features", "improvements"]}>
  ### Features

  * **Cascading Configuration**: Configuration now applies from general to specific patterns
  * Files can inherit rules from multiple matching patterns instead of just one
  * More specific patterns override settings from general patterns

  ### Improvements

  * Updated documentation with configuration examples

  ### Bug Fixes

  * Fix configuration resolution to properly handle multiple matching patterns

  **Full Changelog:** [https://github.com/TRocket-Labs/vectorlint/compare/v2.0.0...v2.0.1](https://github.com/TRocket-Labs/vectorlint/compare/v2.0.0...v2.0.1)
</Update>

<Update label="2025-12-05" description="v2.0.0">
  An LLM-based prose linter that catches subjective writing issues like clarity, tone, and technical accuracy. Think Vale, but powered by AI.

  ## 🚀 Highlights

  * **Multiple LLM Providers**: OpenAI, Anthropic Claude, Azure OpenAI, Google Gemini
  * **Smart Scoring**: Density-based scoring (errors per 100 words) for fair evaluation
  * **Vale Integration**: Seamless integration with Vale CLI for combined analysis
  * **Technical Accuracy**: Hallucination detection with search provider support
  * **Flexible Config**: File-centric rule packs with glob-based targeting
  * **Multiple Outputs**: Native JSON and Vale-compatible JSON formats
  * **MDX Support**: Extended support for React-based documentation

  ## 📦 Installation

  ```bash theme={null}
  npm install -g vectorlint
  ```
