What's new in v0.8.0

Features

• vger daemon — new subcommand for scheduled headless backups without cron
• Server-side init — vger init over REST now uses a single server endpoint instead of 259 individual create_dir calls
• Server single-repo mode — vger-server defaults to localhost and supports single-repo mode for simpler setups
• --worker-threads / --max-blocking-threads — new flags to tune vger-server thread pools
• Server-side pack verification — vger check can verify pack integrity on the server with automatic fallback to client-side
• BLAKE2b content checksums — REST backend uploads include a content checksum for end-to-end integrity
• ZSTD-compressed chunk index — the chunk index is now ZSTD-compressed before encryption, reducing repo overhead

Performance

• Restore overhaul — replaced rayon with pack-affinity partitioning and LRU handle eviction; batch same-file writes; fd-based metadata ops; single-pass item deserialization; group-local buffers saving ~174 MiB RSS; ZSTD decompressor reuse; temp-dir-then-move for crash safety
• Compact — metadata-only size checks in Phase 1 replace full pack downloads

Storage

• Replaced OpenDAL with rusty-s3 + ureq — lighter dependency tree, explicit S3 endpoint configuration required

Refactoring

• Split vger-core into vger-types, vger-crypto, and vger-storage crates
• Extracted vger-protocol crate for shared check/compact logic
• Renamed extract to restore across the codebase
• Added type-safe SnapshotId newtype
• Replaced vger-server TOML config with CLI flags + VGER_TOKEN env var
• Compact threshold default changed to 20%

Bug Fixes

• Fix restore path-based metadata on non-Unix platforms
• Cap GUI log model to prevent unbounded memory growth
• Harden short-read detection and add restore error context
• Fix Windows CI checkout with paths containing colons
