### Added
- Added a weekly executive security digest email for administrators with 7-day firewall telemetry, login abuse summaries, WAF detections, and top targeted paths/rules.

### Fixed
- Fixed custom login logout requests on some Nginx-backed WordPress sites so `/?action=logout` flows no longer fail with upstream `502 Bad Gateway` responses.

## [2.0.3] - 2026-03-10
### Fixed
- Reduced false positives for benign decode-only utilities (e.g., base64 + gzuncompress).
- Reduced false positives for safe `data:image/svg+xml;base64` payloads.
- Disabled auto-fix for low-risk malware findings to prevent accidental code removal.

## [2.0.2] - 2026-03-10

- Reduced malware scanner false positives for base64-decoded signature and key material.
- Avoided false positives from benign `data:image/*;base64,` CSS payloads embedded in PHP/JS strings.

## [2.0.1] - 2026-03-03
### Fixed
- Vulnerability scanner "Vulnerability Overview" panel now stays pinned at the top of the results area while scan content scrolls below it.
- Malware scanner now ignores benign CSS `content:` declarations and static string-literal matches that previously caused false-positive detections.

## [2.0.0] - 2026-02-25
### Added
- Integrity scanner now shows a dedicated "Problematic Integrity Files" block after scan completion with grouped non-OK results.
- Integrity scanner now shows a dedicated "Recommended Next Steps" panel with guidance based on detected statuses and file categories.
- Added a daily cleanup cron task that removes stale integrity queue files from `storage/queues`.
- Malware findings now include expandable code preview blocks with surrounding context lines and a highlighted suspicious line.
- Malware findings now support per-item "Apply Fix" actions with admin permission checks and user confirmation.
- Malware auto-fix creates a backup before patching, attempts targeted snippet removal, and falls back to line quarantine when safer.
- Added web-access hardening files (`.htaccess`, `web.config`, `index.php`) for backup directories used in fallback scenarios.
- Added daily malware-backup cleanup/rotation cron (14-day max age, keep 5 per source file, cap 500 total backups).
- Added a basic Firewall module with MU-plugin loader support for early request handling.
- Added firewall database log storage (`vulntitan_firewall_logs`) with daily retention cleanup.
- Added login protection with IP-based failed-attempt throttling, temporary lockouts, and firewall event logging.
- Added dedicated Firewall admin page with overview metrics, settings controls, and recent log history.
- Added WAF payload rule sets for SQL injection and command injection detection in MU firewall runtime.

### Changed
- Integrity scanner now excludes CSS and SCSS files from queue generation and baseline comparisons.
- Integrity scanner now excludes image formats from queue generation and baseline comparisons.
- Integrity scanner now excludes temporary `.queue` files and shows a contextual notice for internal VulnTitan storage files flagged as `unexpected`.
- Integrity scanner UI now includes a color legend for scan statuses (OK, MODIFIED, MISSING, UNEXPECTED, ERROR).
- Integrity legend is now rendered above the results list (outside the scroll area) and includes a short explanation for each status.
- Admin CSS/JS assets now use `filemtime`-based versioning for automatic cache busting after file changes.
- Vulnerability scanner UX redesigned with a clearer overview, vulnerable-components panel, and structured findings grouped by component severity.
- Malware scanner now uses clearer batch-result UX: per-file status display (clean/infected/skipped/error), streamed scan output, and a final problematic-files summary block.
- Malware scan results now return structured finding metadata (`line`, `severity`, `patterns`, `preview`) to support in-panel forensic preview UX.
- Integrity scanner batch processing is now adaptive (auto-tunes between safe min/max sizes based on server processing time) for faster scans without aggressive spikes.
- Integrity batch API now returns per-batch processing time metadata and uses safer server-side batch limits to balance performance and stability.
- Malware detection engine now includes broader PHP/JS signature coverage (execution, decode, obfuscation, file-write, and suspicious JS constructor patterns).
- Malware scanner now applies stronger combo heuristics (`decode+execution`, `user-input+execution`, `encoded write` chains) to improve real threat detection quality.
- Added per-file malware finding cap (`maxFindingsPerFile`) and extension-aware thresholds to improve scanner stability and reduce noisy/expensive scans.
- Firewall module is now separated from scanners and accessible via its own `VulnTitan > Firewall` submenu page.
- Firewall page UX/UI refreshed with a dedicated security-console layout, improved metric cards, and stronger input/button styling.
- Firewall log database schema is now versioned and auto-migrated with extended event metadata fields (request context, rule data, action/severity, flags, and forensic context JSON) for future features.
- Firewall settings now expose WAF toggles (SQLi/command-injection) and managed whitelist controls in the admin UI.
- Updated plugin/readme metadata (short description, long description, and tags) to reflect Firewall + WAF capabilities.

### Removed
- Removed all "Upgrade to PRO" admin upsell elements (submenu page, top navigation CTA, sidebar promo block, and dedicated upgrade page styles/files).

### Fixed
- Fixed scan panel state reset when switching scan types, so Integrity-only sections and old results are cleared before Malware/Vulnerability scans.
- Malware scanner now renders a dedicated "Problematic Malware Files" panel outside the scrollable results area, consistent with Integrity layout.
- Switching to Integrity or Vulnerability scan now clears/hides Malware problematic and overview panels to avoid stale cross-scan data.
- Integrity scanner frontend now uses guarded AJAX timeout/retry behavior and reduces batch size after transient failures to avoid PHP timeout/error loops.
- Fixed firewall login lockout flow so lockout message is preserved in login auth response and locked attempts no longer re-increment failure counters.

### Security
- Malware auto-fix backups are now stored outside `ABSPATH` by default (`../vulntitan-secure-backups/malware-fixes`) to reduce web exposure risk.
- Web-root backup fallback is disabled by default and can be explicitly enabled with `VULNTITAN_ALLOW_WEBROOT_BACKUPS`.

## [1.0.8] - 2026-02-24
### Changed
