• macOS code signing and notarization — macOS builds are now signed and notarized for a smoother install experience

Performance

• Fix 17 GB peak heap from large command dumps — command_dump stdout is now streamed through the chunker instead of buffered in memory

Bug Fixes

• Fix stress test HTTP opt-in handling and S3 range request signing

Docs & Community

• Add CONTRIBUTING.md with contribution guidelines
• Add security contact to README
• Document concurrent multi-client backup workflow

v0.8.0

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

v0.7.1

Performance

• Streaming compress+encrypt pipeline — backup hot path now produces one Vec per chunk instead of 3–4, with exact-sized pack buffers that avoid glibc ptmalloc2 realloc-shrink pitfalls (~140 MB RSS reduction)
• Eliminate redundant copies on pack upload — zero-copy put_owned for remote backends (S3, REST) avoids one full-pack-size allocation per flush; pre-sized worker chunk Vecs avoid ~7 reallocations per 10 MiB file
• REST backend restore — preallocated get_range buffers and positional write_all_at on Unix halve syscalls per chunk
• LZ4/ZSTD compression — LZ4 writes directly into spare capacity (no zero-fill); ZSTD uses compress_to_buffer to eliminate a ~131 KiB temp Vec per chunk
• FileCache key compaction — replace full path strings with 16-byte BLAKE2b hashes as HashMap keys, saving ~20–35 MB RSS; backwards-compatible deserialization of legacy caches

Bug Fixes

• REST 404 on empty-prefix LIST — list("") now uses the base URL directly instead of appending a trailing slash, with a new repo_list_all handler on the server

Documentation

• Low-resource background backup recipe (ionice, nice, cgroup limits)

Infrastructure

• Extracted shared script library (scripts/lib/) and simplified CLIs for stress.sh, benchmark.sh, and profile.sh

v0.7.0

Security

• Enforce HTTPS by default for remote backends — remote storage URLs now require HTTPS; opt in with allow_insecure_http if needed
• Bind AEAD objects to identity context in AAD — authenticated additional data now includes repository identity, preventing cross-repo ciphertext splicing
• Reduce passphrase exposure in subprocesses and environment — passphrase handling minimizes in-memory lifetime and avoids leaking into child process environments

Features & Improvements

• Parallel large-file pipeline — large files are segmented and chunked in parallel via explicit crossbeam-channel stages, replacing pariter
• XOR dedup prefilter — a fast xor-based filter skips redundant chunk transforms before hitting the full dedup index
• one_file_system default changed to false — backups now cross filesystem boundaries by default, so bind mounts and subvolumes are no longer silently skipped. Set one_file_system: true to restore the old behavior.
• Walk optimization — skip redundant symlink_metadata calls for files when one_file_system is enabled

Bug Fixes

• Fix deadlock between pariter reorder buffer and ByteBudget
• Make delete-repo safe by classifying keys and fixing recursive list
• Remove trailing encrypted header from pack files
• Server: recover from RwLock poison instead of panicking
• Windows: use HANDLE type alias for windows-sys 0.59 compatibility (Rust 1.93)
• Fix clippy 1.93 lint for set_readonly(false) in tests

Dependencies

• Replace filetime and http-body-util with internal implementations
• Replace rpassword and dirs with internal helpers

v0.6.3

Memory Optimization

This release dramatically reduces peak memory usage across all operations through mmap-backed storage and streaming processing:

• Mmap-backed pack assembly: Replace heap pack buffers with mmap-backed assembly, reducing backup heap usage from 384 MiB to ~4 MiB
• Pack buffer pool memory reduction: ~40% reduction in pack buffer pool memory (640→384 MiB) before mmap conversion
• Tiered dedup index: Add mmap cache and xor filter for memory-efficient chunk deduplication
• Index-free extract: Restore files without loading the full chunk index into memory, using mmap restore cache
• Streaming item serialization/deserialization: Eliminate temp allocations during backup and reduce extract peak memory
• Incremental index update: Reduce save_state() peak memory by flushing incrementally (~138M saved)
• Open-phase optimization: Reduce open-phase peak memory from ~227M to ~128M
• Restore planner compaction: Use SmallVec and filtered chunk index for ~40% better throughput

Features

• cache_dir config option: Control where mmap temp files and cache data are stored
• Reuse ZSTD compression context: Thread-local Compressor reuse reduces allocation churn
• Pre-size FileCache HashMap: Use old cache length for initial capacity

Bug Fixes

• Release pack buffer pool in save_state() to avoid retaining memory past its useful life
• Recalculate pack writer targets in load_chunk_index() for correct sizing

Infrastructure

• Add profiling build option to release workflow
• Add linux_only option for manual release workflow runs

• Add SAFETY comments to all unsafe blocks
• Replace .unwrap() with .expect() or if-let in production code paths
• Remove unused dependencies: indicatif, hostname, whoami, dialoguer

Refactoring

• Split monolithic config.rs into focused submodules (defaults, deserialize, hooks, limits, resolve, sources, types, util)
• Narrow internal config visibility with pub(super) and #[serde(deny_unknown_fields)]
