[v0.4.3] — 2026-06-14

Fixed

• Dashboard counts — "Saves" now shows .bak recovery file count, "Backups" shows .tar.gz archive count
• Backup mtime preservation — tar archives now store source file modification times, preventing epoch dates on restored files
• Navigation bound — restore backup picker no longer stops before migrated entries
• Save folder dialog — pre-fills with the current path if one is already set
• Disclaimer sentinel not removed on decline — rejecting the disclaimer now deletes the NOTALTERRA_LICENSE_ACCEPTED sentinel file, so the disclaimer reappears on the next launch. Previously, acceptance was irrevocable even through the "View disclaimer" menu item.

[v0.4.2] — 2026-06-09

Added

• Info dialog — non-blocking popup (no button) for backup-in-progress status
• INI restore picker header — pinned header with "INI Backup" / "Size" columns
• Header pinned on restore pickers — column header + blank spacer stay fixed
• Spacer row between list content and status bar on all screens
• Split-layout backup picker — pip (►) highlight replaces background bar, right pane shows live GVAS metadata for the selected backup (loads on highlight, cached per file)
• Persistent config (app.ini) — save-folder and backup-root paths now survive sessions, stored under data_local_dir/NotAlterra/config/
• Set backup location menu entry — choose where save and UE5 backup archives are stored; defaults to ~/NotAlterra
• Blank separator lines in menus — visual grouping, auto-skipped on navigation
• docs/CVE_TEMPLATE.md — structured vulnerability disclosure template
• docs/BUG_REPORT_TEMPLATE.md — user-facing bug report reference with privacy warnings
• .github/PULL_REQUEST_TEMPLATE.md — PR checklist matching CI gates
• Safe harbor clause in SECURITY.md — legal protection for good-faith security researchers

Changed

• Layout alignment — restore backup and INI restore headers aligned with data
• Column widths — Backup column widened to 38 chars for longer labels
• Size column — right-aligned, header centered above values
• Main menu — entries shifted 1 position left
• INI submenu — entries aligned with main menu, header cyan + 3 right
• Highlight color — all picker highlight color changed to yellow
• Backup creation — no intermediate spinner page; info popup + summary dialog
• INI restore picker — now uses pinned_header, matching restore backup style
• File picker layout — horizontal 60/40 split: file list on left, metadata preview on right. Slot, Description, Date columns only
• Main menu pip highlight — ► replaces full-row cyan background (legacy highlight code retained for other pickers)
• Config directory — app.ini and sentinel moved from exe_dir/ to data_local_dir/NotAlterra/config/ (platform-standard)
• Logs directory — transaction.log moved from exe_dir/logs/ to data_local_dir/NotAlterra/logs/
• UE5 ini backups — stored in backups/ue5/ under the backup root instead of backups/config/
• Menu labels — "Set save folder" renamed to "Set Subnautica 2 location", descriptions updated
• Local builds — compiled with cargo build for both Linux and Windows targets
• Context-aware header path — the right side of the title bar shows the relevant file location for the current menu or submenu item (save folder, backup root, or ini Config\Windows path)
• Human-readable backup labels — archive filenames are now displayed as Full Backup — <date> and Pre-restore — <date> in the restore picker instead of raw .tar.gz filenames
• Backup Types section in README — explains Full Backup vs Pre-restore in plain language so users understand the safety flow
• Archive integrity check — check_tar_gz_integrity() verifies gzip magic bytes before restore; corrupt files show a warning description and Enter is blocked
• Context-aware restore descriptions — restore picker shows different descriptions for full backup, pre-restore, migrated, and corrupted archives
• Consistent warning spacing — all ⚠ messages use double-space formatting

Fixed

• Header/data misalignment — total widths matched so {:>8} fields align

Removed

• "Inspect save files" menu entry — metadata is now visible inline in the backup picker right pane. action_inspect_saves() code retained.
• i key handler in backup picker — redundant with live metadata pane
• Outdated privacy claims — docs no longer state "no data stored" or "session-only"; now accurately describe app.ini persistence

Security

• GitHub Private Vulnerability Reporting as primary disclosure channel, email as fallback
• Safe harbor — explicit no-litigation commitment for good-faith reporters following the disclosure policy
• CVSS v4 scoring documented in Dependabot advisory for lru transitive dependency (low severity, not actionable)
• All paths in app.ini documented as potentially containing the system username — plain text, never transmitted

[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.
• Log migration — existing transaction.log is moved into logs/ on first launch, appended to the new location.

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).

[v0.1.2] — 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

• Dashboard stats filter by savegame_* prefix
• OK dialog width padding prevents text clipping
• 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
