All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.5.0] - 2026-07-28

Added

• --all / -a staging of tracked modifications and deletions before generation
• Exact machine-readable output with --stdout, including non-rewriting alter
• Sequential multi-candidate generation and selection with --generate N / -g N
• Invocation-only prompt guidance with --prompt TEXT / -p TEXT
• Repository-local prepare-commit-msg management through cgen hook
• Authenticated live model discovery and searchable selection through cgen model and the configuration editor

[1.4.1] - 2026-07-23

Changed

• Updated all Rust dependencies, including the ureq 3, toml 1.1, sha2 0.11, inquire 0.9, colored 3, and shlex 2 major releases
• Raised the MSRV to Rust 1.85, the minimum required by the updated dependency graph
• Updated GitHub Actions to their current supported major releases

Fixed

• Try fallback presets when a provider rejects a request as too large (HTTP 413)
• Include the path and line number for sensitive-content findings, and ignore the documented your-key-here API-key placeholder

[1.4.0] - 2026-07-23

Added

• Sparse project .env overrides with an interactive “Inherit global value” action
• Configurable diff byte/sensitive-path guards and explicit --allow-large-diff / --allow-sensitive overrides
• Linux ARM64 and x86_64 musl release artifacts with SHA-256 manifests
• Rust 1.74 MSRV declaration and CI gate
• One-shot self-correction: when the LLM returns an invalid commit message, the validator error and rejected attempt are fed back to the model for a corrective retry before failing
• ACR_WARN_LLM_FILES_ENABLED / ACR_WARN_LLM_FILES_THRESHOLD: warn on the count of files actually sent to the LLM (the token-relevant subset), merged with the staged-files warning into a single confirmation that reports the payload size
• Staged-file listing marks files excluded from the LLM payload with (not sent to LLM)
• ACR_MAX_OUTPUT_TOKENS to configure the LLM completion token cap (default 512, previously hard-coded)

Changed

• Local .env updates preserve unrelated variables, comments, and absent inherited settings
• Configuration parsing rejects invalid booleans, integers, push modes, gitmoji formats, templates, locales, headers, and globs
• Provider fallbacks share one total deadline and run only for classified transient failures
• Preset/config/cache writes are owner-only, lock-protected, and atomically replaced
• History cache entries use stable identifiers, deduplicate rewrites, and retain the latest 200 commits
• Self-update targets the current installation, pins the release version, and verifies checksums before replacement
• Release CI builds with --locked, validates the requested tag, publishes checksums, and gates crates.io publication behind the release
• CI now enforces formatting, strict Clippy, cross-platform tests, MSRV, dependency audit, installer syntax, and aligned coverage
• Locked dependencies use patched TLS, error-handling, randomness, and test-serialization releases; terminal UI features avoid unnecessary unmaintained/yanked transitive paths while preserving Rust 1.74 support
• Rewrote the base LLM prompts around current prompt-engineering research: enumerated commit types, imperative-mood and header-length rules, anti-fabrication constraints, mode-matched few-shot examples, and explicit one-liner precedence
• Staged diffs are sent wrapped in <diff> tags as data to describe, with the task restated after the diff
• A blank ACR_LLM_SYSTEM_PROMPT now selects the built-in default prompt, and configs still storing a retired shipped default are upgraded to the current default automatically
• The config view shows (built-in default) for an uncustomized system prompt instead of the stored text
• Anthropic requests pin temperature to 0, matching the other providers
• Conventional Commit shape is enforced on LLM output only; templated and manually edited messages receive structural validation (empty/NUL)
• Staged-file warnings are evaluated after diff filtering, so hard safety gates run before any confirmation prompt
• cgen prompt and cgen undo no longer perform the startup update check

Fixed

• Partial global TOML files no longer turn omitted default-true booleans off
• Unicode API keys/prompts no longer panic during masking or truncation
• Interpolation no longer mutates process environment or silently removes missing variables
• Confirmation cancellation can no longer select an affirmative default
• LM Studio receives the complete system instruction
• Empty, malformed, fully excluded, oversized, or sensitive diffs are stopped before provider calls
• Generated, regenerated, templated, and manually edited commit messages are validated before Git receives them
• Non-HEAD/root rewrites record the rewritten commit identity rather than HEAD
• Root-commit undo keeps changes staged
• Pushed rewrites use an explicit force-with-lease path and created tags are pushed explicitly
• Selected-repository history uses that repository for git show
• Concurrent preset/cache writes no longer silently overwrite one another
• The updater uses the published auto-commit-rs crate rather than a nonexistent package
• Non-English locales no longer instruct the LLM to translate Conventional Commit types, which produced headers that failed message validation
• Fallback presets that differ from the active configuration only by API headers are attempted instead of silently skipped

Removed

• High-MSRV edit dependency; editor launching is handled internally
• Unused enabled flag inside the presets file's [fallback] section (existing files containing it still parse)

[1.3.2] - 2026-06-25

Added

• --set KEY=VALUE flag to override any setting for a single run (ephemeral, never persisted); auto_update excepted
• --diff-include GLOB / --diff-exclude GLOB flags to refine which files are sent to the LLM for a single run (allow-over-deny precedence)

[1.3.1] - 2026-04-09

Fixed

• Fixed oLLaMa streaming content issue

[1.3.0] - 2026-04-06

Added

• Added oLLaMa as a built-in provider

[1.2.2] - 2026-03-05

Fixed

• Fixed prompt issue where smaller LLMs weren't grasping single-line commits

[1.2.1] - 2026-03-02

Fixed

• Gitmoji spec no longer overrides the Conventional Commit spec
• When editing a LLM-generated message you start editing from the existing message

[1.2.0] - 2026-03-02

Added

• ACR_DIFF_EXCLUDE_GLOBS configuration: exclude files from LLM analysis by glob pattern while still committing them
• Default exclusion patterns for common binary/generated files: *.json, *.xml, *.csv, *.pdf, *.lock, images, fonts, minified assets
• Seven new built-in LLM providers: Grok, DeepSeek, OpenRouter, Mistral, Together, Fireworks, Perplexity
• LLM presets: save, load, rename, duplicate, delete, export/import reusable provider configurations via cgen config
• Fallback order: automatic retry with alternate LLM presets when the primary provider returns an HTTP error
• ACR_FALLBACK_ENABLED configuration flag (default: enabled) to toggle LLM fallback behavior
• Per-repository commit cache: track which commits were AI-generated
• cgen history subcommand to browse AI-generated commits per repository (with git show integration)
• ACR_TRACK_GENERATED_COMMITS configuration flag (default: enabled) to toggle commit tracking
• Preset management menu in cgen config (save current as preset, load preset, manage presets, configure fallback order)
• Preset change tracking: warns when loaded preset fields are modified and offers to update on save
• Export/import presets as TOML (with optional API key redaction)
• cgen preset standalone subcommand to manage LLM presets directly
• cgen fallback standalone subcommand to configure fallback order directly
• Config view: "Show descriptions [?]" toggle to display help text for each setting
• Config view: "Search settings [/]" to find settings by name (auto-expands matching groups)
• Config view: improved color variance with bright white for groups, bright cyan for subgroups

Changed

• ACR_AUTO_UPDATE is now a global-only setting and will not be written to local .env files
• call_llm now uses call_llm_with_fallback internally, enabling automatic provider retry
• generate_final_message reports which fallback preset was used (if any)
• Config menu now includes preset and fallback management entries
• All (y/N) confirmation prompts replaced with interactive Select menus showing "Yes"/"No" options
• Config view: selected item header now strips tree-drawing characters for cleaner display
• Preset management: restructured menu - select a preset first via "Manage existing preset...", then choose action (Rename/Duplicate/Delete)

Fixed

• Cursor no longer resets to top of view when collapsing headers on the cgen config view

[1.1.0] - 2026-02-24

Added

• cgen update subcommand to manually update to the latest version
• ACR_AUTO_UPDATE configuration flag (defaults to unset; prompts on first run)
• Automatic version checking against GitHub releases on every run
• Auto-update support when ACR_AUTO_UPDATE=1 (updates silently before proceeding)
• Update warning displayed at the end of output when a newer version is available and auto-update is off
• cgen prompt subcommand to print the LLM system prompt without running anything
• cgen config now auto-detects git repo: prompts for global vs local scope inside a repo, opens global directly outside one

Changed

• Staged files display now uses tree-style characters (├──, └──) instead of bullet points
• Boolean config fields display "enabled"/"disabled" instead of "1 (yes)"/"0 (no)" in the interactive config UI
• Interactive config groups settings into collapsible tree sections (Basic expanded, Advanced collapsed with subgroups)
• cgen config --global flag removed; scope selection is now interactive when inside a git repo

[1.0.0] - 2026-02-23

• Initial release of the tool
