What's New in v0.4.0

A major release with a new desktop GUI, significant performance improvements, and many usability enhancements.

Desktop GUI

• New Slint-based desktop GUI (vger-gui) with tabbed interface, per-repo/source backup controls, and ComboBox selectors
• System tray icon with scheduled backup support
• Encryption mode selection from the GUI
• Available on macOS and Linux

Performance

• Pipeline parallelism — overlaps I/O and CPU during backup for significantly faster throughput
• Cross-file batching for small files, reducing per-file overhead
• Parallel ChunkId hashing via rayon thread pool
• Streaming backup support for large file sets without excessive memory use
• Rayon-parallelized chunk transform pipeline (compress + encrypt)
• Fix for unbounded memory growth when backing up large files
• S3 upload tuning and simplified upload path

New Features

• Multi-repository configuration — manage multiple backup targets in a single config file
• Hooks system — run shell commands before/after any vger command
• vger combined — single command to run init, backup, prune, compact, and check
• vger info — per-repository stats (size, chunk count, snapshots)
• vger mount — WebDAV server with browser-friendly HTML file browser
• command_dumps — capture command output (e.g., pg_dump) directly into backups
• Resource limits — built-in CPU, I/O, and network throttling for backups
• Live TTY progress with indicatif progress bars during backup
• Configurable retry with exponential backoff for remote backends
• Extended attributes (xattr) preservation on Unix
• Environment variable expansion in YAML config files
• Tilde expansion (~) in repository URLs and source paths
• Config resolution with search paths and VGER_CONFIG env var
• Windows support (CLI only)

CLI Improvements

• Renamed create → backup and extract → restore for clarity
• Renamed archive → snapshot across the entire codebase
• Snapshot ID accepted as positional argument in delete
• list now shows source paths and unified labels
• Combine multiple source paths into a single snapshot
• Improved table styling for CLI output

Bug Fixes

• Fix stale file cache causing empty restores after delete + compact
• Fix backup correctness issues in edge cases
• Hardened repository operations with backend-native locking and repack

Infrastructure

• CI workflow for main branch with integration tests
• Release builds for Linux (x86_64), macOS (aarch64), and Windows (x86_64)
• Expanded test coverage and reliability improvements
• License changed to GPL-3.0-only (to align with Slint UI dependency)

Downloads

Each archive contains vger (CLI), vger-server, and vger-gui (Linux/macOS only). SHA256 checksums are provided for all artifacts.
