# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0.html),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [1.5.3] - 2025-12-23
### Added
- **Torrent backend selection:** magnet links can now be handled by different backends.
- **Default torrent behavior (no extra features):** if the URL is a `magnet:?` link, KGet opens it using the system's default BitTorrent client (automatic detection via OS handler).
- **Optional Transmission RPC backend:** build with `--features torrent-transmission` and set `KGET_TORRENT_BACKEND=transmission` to download via Transmission RPC.
- **Transmission settings helper:** centralized settings for host/port/paths and optional auth (env-compatible).
### Changed
- **GUI footer:** app version is displayed in the bottom-right corner.
- **GUI window sizing:** improved default/min window sizing for a better first launch experience.
### Fixed
- Build fixes and feature-gating improvements for optional components (torrent backends / GUI split).
## [1.5.2] - 2025-12-19
### Added
- **ISO Smart Handling**: Automatic detection of `.iso` files via URL and MIME type.
- **Corruption Prevention**: ISO files now bypass decompression/optimization layers to ensure binary 1:1 integrity.
- **Integrity Verification**: Added optional SHA256 checksum calculation at the end of ISO downloads.
- **Windows Dual Mode**: The application now runs without a console window when launched via Explorer, but automatically attaches to the terminal when run via CLI.
### Fixed
- **Memory & Disk Optimization**: Refactored `AdvancedDownloader` to use streaming writes with `BufWriter`, drastically reducing RAM usage and preventing 100% disk active time issues.
- **Verification Prompt**: Fixed bug where integrity check was running automatically in advanced mode; it now correctly asks the user for confirmation.
- **UI/UX**: Cleaned up terminal output during parallel downloads for a smoother progress bar experience.
- **GUI Icon**: Fixed issue with loading the application window icon.
- Fixed Rust compiler error `E0382` regarding `Mime` type ownership in `download.rs`.
- Improved parallel chunk writing safety for binary-heavy files.
## [1.5.1] - 2025-12-18
### Added
- Optional `gui` Cargo feature to make GUI dependencies opt-in; compile with `--features gui` to enable GUI support.
- Top-level convenience functions: `kget::download(...)` and `kget::advanced_download(...)` for easier library usage.
- `create_progress_bar_factory(...)` exported to let consumers create `indicatif` progress bars.
- `examples/lib_usage.rs` example demonstrating library usage.
- Docker development instructions and `docker-compose` integration to simplify building, testing and contributing.
### Changed
- Updated README and `LIB.md` with library usage instructions and examples.
- `CONTRIBUTING.md` and translations updated with Docker contributor workflow.
- GUI code split: `gui_types` module added so CLI builds without GUI feature.
### Fixed / Misc
- Minor documentation fixes and translation updates (PT-BR/ES).
## [1.5.0] - 2025-05-26
### Added
- New public Rust crate: KGet can now be used as a library in your own Rust projects, click [here](LIB.md) to see more.
- Improved GUI: larger fonts, better layout, and more intuitive controls.
- Clipboard integration for easy pasting of URLs.
- Download button and cancel button now always visible and functional in the GUI.
- **Interactive mode:** Run `kget --interactive` for a REPL-like experience with commands such as `download <url> [output]`, `help`, and `exit`.
### Changed
- Project renamed from "KelpsGet" to "KGet" for simplicity and consistency.
- Versioning scheme updated from 0.1.4 to 1.5.0 to allow for more frequent minor updates and clearer release tracking.
- Features list moved from README to CHANGELOG for easier maintenance and to keep the README concise.

### Changed
- Refined output path determination to align comportamento with `wget`.
- Ensured `final_path` is always absolute to prevent "No such file or directory" errors in CWD.
- Updated README in English, Portuguese, and Spanish to reflect all new features and setup instructions.
### Fixed
- Resolved "No such file or directory" error when downloading without `-O` by ensuring absolute paths.
- Corrected `validate_filename` to only check the base filename, not the full path.
