NotAlterra/CHANGELOG.md

Changelog

All notable changes to NotAlterra are documented in this file.

---

[v0.4.0] — 2026-06-03

Added

• --help / -h flag — displays usage information
• tar.gz backup format — one archive per backup event, all slots in one file. Standard tar -xzf recovers data without the tool (no vendor lock-in). Safeguards: atomic write (.tmp → rename), per-file SHA256 manifest, per-entry restore without full decompress.
• Migration path — old NotAlterra_Backups/ directory-tree backups are automatically detected and imported into the new tar.gz format
• Bus factor mitigation — documented in GOVERNANCE.md: emergency signing key stored with a non-technical trusted person, revocable if compromised

Changed

• File layout — backups stored in backups/saves/ (tar.gz), backups/config/ (.ini archives), logs in logs/transaction.log
• Stale config.ini removed on first launch from prior versions
• Dependencies — added tar + flate2 (pure Rust, +~150KB binary)

Testing

• 6 migration unit tests (basic, empty, nonexistent, integrity, filtering, idempotency)
• Full round-trip integration tests for tar.gz backup/restore
• Fuzz target for backup round-trip (10s: 11,717 runs, zero crashes)
• File permissions fixed in tar headers (0o644 instead of 0o000)

[v0.3.2] — 2026-06-02

Added

• Lightweight startup check — on launch, the app silently checks the current user's default save locations (%LOCALAPPDATA% on Windows, Proton + XDG data on Linux). No scanning of other profiles or system drives. If nothing is found, use Set save folder as before.
• Migration notification — old backups in NotAlterra_Backups/ are migrated silently on first launch with a log entry. The user is informed their original data remains untouched.

Removed

• config.ini eliminated entirely — no save path, disclaimer flag, or scan timestamp is written to disk anymore. The save folder is session-only, entered via Set save folder. The disclaimer acceptance is tracked via a 0-byte sentinel file (NotAlterra_LICENSE_ACCEPTED) alongside the binary.
  • src/config.rs reduced to sentinel utilities and exe_dir()
  • AppConfig, load_config(), save_config() removed
  • Integration tests for config round-trips removed (replaced by sentinel test)

Changed

• get_ini_path() now derives the Config/Windows path from the save folder at runtime — no cached ini_path in memory or on disk.

[v0.3.1] — 2026-06-02

Added

• Patrolling whale in the Set save folder input dialog (was missing the bottom separator present on all other screens)

Fixed

• Path injection via paste — control characters (newlines, tabs, null bytes) are now stripped from user-provided paths before they reach config.ini or transaction.log
• Draft releases — CI now creates releases as drafts. You can download and test the binaries before publishing them live.

Removed

• Locate save files menu item — the deprecated auto-discovery entry point is gone. Set save folder is the only path for configuring the save location. The discovery.rs module remains for validate_custom_path and derive_ini_path but is marked for removal in v0.4.0.

[v0.3.0] — 2026-06-02

Added

• SECURITY.md with vulnerability disclosure policy
• Release checklist in GOVERNANCE.md
• 32-test integration suite (guard, config, ops, gvas, ini backup/restore)
• Fuzz target for GVAS parser (parse_gvas)
• Second fuzz target (full_metadata) — exercises IntProperty, DoubleProperty, and additional StrProperty/BoolProperty code paths
• fuzz/Cargo.toml manifest with both fuzz targets registered
• Set save folder menu option — manual path entry with clipboard paste support (bracketed paste mode), replaces auto-discovery as the primary way to set the save location
• cargo clippy, cargo audit, and cargo-deny in CI
• deny(unsafe_code) in library crate
• Build script validates CHANGELOG has current version entry

Fixed

• Index-out-of-bounds panic in all four GVAS property extractors (extract_str_property, extract_bool_property, extract_int_property, extract_double_property) when a property name appeared too close to the end of the buffer — discovered by fuzzing the existing parse_gvas target

Deprecated

• Auto-scan for save folders (Locate save files menu item / discovery.rs module). Scans user profiles and system directories, which is a privacy concern. Shows a deprecation notice once per session. Scheduled for removal in v0.4.0 — use Set save folder instead.

Changed

• Zero compiler warnings
• Example dump_samples compiles and runs
• fuzz/target/ added to .gitignore
• Fuzz targets rewritten from #[fuzz] attribute to libfuzzer_sys::fuzz_target! macro for nightly-toolchain compatibility
• No auto-scan on startup — the application no longer scans user profiles and system drives for save folders at launch. Only the cached path from config.ini is loaded.
• Menu is always 9 items — Set save folder is always visible. Locate save files is always visible (with deprecation label). No conditional hiding or index remapping.
• ensure_save_folder() and get_ini_path() no longer fall back to discover_save_folders(). They use the cached path or error with a message.
• is_cloud_path() removed — was only used by the discovery-era cloud detection path.
• Zero clippy warnings on CI — fixed collapsible_match (6 instances), empty_line_after_doc_comments, and manual_is_multiple_of lints from rustc 1.95 nightly.
• KNOWN_ISSUES.md moved from docs/ to project root — reflects v0.3.0 privacy improvements (manual path entry live, discovery deprecated).

Notes

• Working copy diverged from remote after signing the previous commit on a different clone. Resolved via git reset --soft origin/master (no content lost, identical tree).

[v0.2.3] — 2026-06-01

• Zero compiler warnings (deny(unsafe_code), allow(dead_code) where intentional)
• Example dump_samples compiles and runs
• 100% function doc coverage with automated check script
• last_path → save_path, last_scan → save_scan, config_path → ini_path
• Windows executable renamed to NotAlterra.exe

Security

• Logged paths truncated at Subnautica2/ — personal paths removed

[v0.1.2] — 2026-06-01

• Zero compiler warnings (deny(unsafe_code), allow(dead_code) where intentional)
• Example dump_samples compiles and runs
• Replaced process detection (tasklist/pgrep) with startup warning modal to avoid Windows Defender false-positive (Trojan:Win32/Wacatac.C!ml)
• "Online" / "Local" renamed to "Multiplayer" / "Single Player" throughout
• Date format changed to YYYY-Mon-DD HH:MM
• Status bar text removed — whale-only row
• "Back" option added to .ini submenu
• All save/ini operations now show file counts

Fixed

• .ini backup now shows OK confirmation dialog
• .ini restore returns file count

• File picker column alignment tightened

[v0.1.1] — 2026-05-31

Changed

• Zero compiler warnings (deny(unsafe_code), allow(dead_code) where intentional)

• Example dump_samples compiles and runs

• "Recover .sav file from .bak" renamed to "Recover save file" (less technical)

• Save/Backup labels pluralize based on count

• Zero compiler warnings (deny(unsafe_code), allow(dead_code) where intentional)

• Example dump_samples compiles and runs

• Improved game-running exit message — explains why save files are at risk

Fixed

• Background scan thread panic no longer hangs the application
• Arrow-key navigation no longer overshoots — KeyEventKind::Release events filtered
• GVAS metadata popup renders all 11 fields (was clipped to 2 because of Paragraph::new(Span))
• Header path now shows tail of path (e.g. …\Subnautica2\Saved\SaveGames) instead of truncated prefix
• Confirmation popup always appears — hard require_backup block replaced with soft warning

Security

• Game-running detection at launch and before each destructive operation
• .ini delete guarded by requiring at least one ini_backup_* directory
