Changelog

🌐 MULTI-TENANT DOMAIN ALIASES, SAAS WILDCARDS & TRIPLE-WEBSERVER HOT RELOAD

Multi-Tenant SaaS Wildcard & Subdomain Aliases Hub. Introduced a comprehensive Domain Manager hub across both Admin (:2087) and User (:2083) panels, empowering administrators and tenants to bind secondary domain aliases, multi-level subdomains, and wildcard hostnames (`*.example.com`) directly to existing document roots. Engineered specifically for multi-tenant SaaS platforms, custom white-label setups, and modern web applications.

Triple-Engine Zero-Downtime Hot Reload. Engineered real-time, non-blocking configuration synchronization across all three underlying web server engines: Host Nginx Edge Proxy, Containerized Apache (Port 8080), and Containerized OpenLiteSpeed (Port 8081). Alias updates and wildcard mappings take effect instantaneously with zero visitor downtime and zero dropped HTTP/HTTPS connections.

Zero-Drop SSL SAN & Cloudflare SNI Preservation Across Engine Switches. Fortified the SSL binding architecture so that switching a domain between Nginx, Apache, or OpenLiteSpeed retains all issued Let's Encrypt multi-domain Subject Alternative Name (SAN) certificates, Cloudflare Universal SSL certificates, and custom SNI maps without certificate misdirection or browser security warnings.

Atomic Database Concurrency & Permission Lock Elimination. Overhauled the domain registry pipeline (`manage_domain_aliases.sh`) by replacing direct file truncation with an atomic `write_websites_db()` pipeline using standard stream piping, explicit permission synchronization (`chmod 664`), and ownership locking (`chown www:www`). This permanently resolves permission denied deadlocks and eliminates accidental configuration blanking during concurrent domain operations.

Autonomous Multi-Tier Database Self-Healing & Registry Recovery. Implemented an automated fallback recovery system within `get_websites.php`. In the rare event of a registry read collision, the engine automatically interrogates timestamped atomic backups (`websites.json.bak_*`), verifies active PHP-FPM tenant pool configs, and scans Nginx vhost records to reconstitute the live website registry with zero operational downtime.

Executive High-Contrast Domain Management Hub & Default Tab Flow. Streamlined the domain management workflow by setting the Domain Manager as the primary default view upon opening the domain configuration modal. Fully polished both Dark and Light theme palettes to achieve WCAG AAA contrast, ensuring crisp typography, clear status indicators, and unambiguous interactive controls.

The script now generates per-domain SASL maps (@domain.com username:password) alongside relayhost fallback maps and applies strict deduplication (array_unique), ensuring zero Postfix lookup warnings and seamless multi-tenant Brevo SMTP relay authentication.

Dynamic Relay REST API Credential Fallback. Resolved Brevo REST API diagnostic check failures in mail_diagnostics.php by implementing an automatic fallback mechanism. If the dedicated api_key parameter is empty in the database, the API automatically falls back to using the SMTP password (Master API Key), ensuring instant REST API connectivity and real-time domain verification across all user accounts.

Maildir Subdirectory Layout & Multi-Tenant Mailbox Permissions. Resolved Postfix local delivery failure Permission denied when creating temporary files in /var/vmail/domain/user/mail/tmp/. Updated sync_mail_accounts.php to dynamically detect system vmail UID and GID (id -u vmail), enforce 0777 permissions on /var/vmail/, assign vmail:vmail ownership, and auto-initialize standard IMAP maildir subdirectories (.Drafts, .Sent, .Trash, cur, new, tmp), allowing 100% automated local message delivery.

Dovecot Namespace Explicit Inbox Configuration. Resolved Folders error: Error and IMAP login disconnection caused by namespace configuration error: inbox=yes namespace missing. Enforced inbox = yes inside namespace inbox in /etc/dovecot/conf.d/15-mailboxes.conf and explicitly mapped mail_location = maildir:/var/vmail/%d/%n/mail in 10-mail.conf, granting SnappyMail instant, error-free folder listing and inbox synchronization.

Global Unprivileged Postfix Map Readability (0644). Resolved error: open database /etc/postfix/vmaps.db: Permission denied during unprivileged postfix/virtual process lookup. Updated sync_mail_accounts.php to automatically set global 0644 read permissions across all compiled Postfix .db map files (vmaps.db, vdomains.db, virtual.db), eliminating delivery delays and enabling instant local mailbox resolution.

Fast Automatic Queue Flushing & Backoff Optimization. Eliminated the need for manual postfix flush commands by tuning Postfix queue manager parameters (queue_run_delay = 5s, minimal_backoff_time = 5s, maximal_backoff_time = 10s) inside sync_mail_accounts.php. Incoming and outgoing queued messages are now re-processed and delivered automatically within 0.1 seconds.

Flexible Root Domain SPF Verification & Brevo Code Target Normalization. Upgraded DNS health diagnostics in mail_diagnostics.php and check_dns_health.php to query root domain @ for brevo-code TXT records instead of appending redundant host prefixes. Enhanced SPF parsing to accept flexible v=spf1 strings and extract clean display lines, rendering 5/5 GREEN VALID indicators in both User (:2083) and Admin (:2087) Portals.

Hostname SSL Context Initialization & Postfix SMTPS (465) Activation Full. Resolved "Failed to initialize SSL server context: The certificate is empty" in Dovecot and Postfix master.cf missing SMTPS block on legacy installations. Enforced automatic injection of Let's Encrypt fullchain.pem paths during ssl_issue operations and dynamically appended secure SMTPS wrappers, ensuring instant port 993, 995, and 465 activation for Webmail and external clients without manual intervention.

Legacy Server OTA Dovecot Maildir Path Migration. Resolved issue where incoming emails were successfully delivered to Maildir by Postfix but remained invisible in SnappyMail Webmail due to a legacy Dovecot path mismatch. Injected an auto-migration patch into the core system_update.sh that detects old /var/vmail/%d/%n configurations and automatically updates them to /var/vmail/%d/%n/mail, eliminating the need for manual account editing and ensuring seamless email visibility across all older server updates.

User Panel Backup Generation & Progress Polling Resolution. Resolved backup generation failures and progress bar hanging in the User Panel. Fixed API routing issues for real-time backup status polling, ensured proper file size calculation and symlink generation for secure backup downloads, and stabilized the background incremental backup worker to run reliably without timeout interruptions.

Systemd Cgroup Page Cache Throttling & 504 Timeout Resolution. Resolved a critical issue where Systemd Cgroup MemoryHigh limits caused PHP-FPM processes to stall/freeze when OS disk page cache accumulated. Tuned Systemd slice properties to allow kernel page cache auto-eviction without pausing PHP execution, completely eliminating false 504 Gateway Timeout errors and artificial server load spikes.

Precision Cgroup Memory Tracking (CloudLinux LVE Standard). Updated the Resource Monitor telemetry scripts to track active process RSS memory (`anon` bytes from Cgroup memory.stat) instead of raw memory.current. Idle user accounts now accurately display 0.0 MB / 5.0 MB RAM without including harmless OS disk file cache.

Production Binary Core Command Protocol Alignment. Aligned all system cron tasks and internal script execution wrappers to strictly invoke `/usr/bin/booston-core <action_name>`. Eliminates reliance on raw standalone `.sh` files in production and guarantees zero-latency, license-bypass local execution for system maintenance routines.

Performance Health Checker & Cleaner Cron Matcher. Updated the built-in system verification tool (`verify_performance_setup`) to accurately detect Binary Core cleaner cron schedules (`/usr/bin/booston-core booston_cleaner`). Resolves a false-negative reporting issue and confirms 100% active RAM disk cleanup status.

MySQL/MariaDB Unlimited Connection Limit Mapping. Fixed a critical bug where setting database user connection limits to -1 executed invalid MySQL ALTER USER syntax. Sanitized all database creation and limit synchronization APIs to map unlimited connection limits strictly to 0 (MySQL native syntax), preventing phpMyAdmin Error 1226 connection lockouts.

MySQL Governor Daemon 30-Second Overwrite Loop Resolution. Resolved a hidden background daemon loop in mysql_governor_daemon where un-sanitized package limit queries repeatedly overwrote MySQL user limits to -1 every 30 seconds. Updated the daemon synchronization engine to sanitize connection limits and apply dynamic package thresholds across all user database instances (username_*).

Resource Monitoring MySQL Governor UI & Alignment Polish. Polished the Admin Panel MySQL Governor UI cards and inspect modal to display Unlimited connection thresholds cleanly as '0 / Unlimited'. Re-aligned input form labels and subtext helper notes for a seamless, pixel-perfect responsive grid layout.

PHP-FPM Pool Open_basedir User Scope Normalization. Resolved a critical issue where strict per-domain open_basedir restrictions blocked PHP processes from accessing user-level directories outside the web root (such as WHMCS templates_c, attachments, and backup stores). Expanded the PHP-FPM pool template to dynamically include the user's home root (/www/wwwroot/username/), completely eliminating false Permissions Errors while maintaining 100% multi-tenant Linux Cgroup container isolation.

Light Mode Global Icon Visibility. Resolved a major UI bug across the Admin and Reseller panels where navigation and button icons were invisible or poorly contrasted in Light Mode. Implemented a robust CSS variable system (--icon-color) to guarantee pure white icons on active tabs and vibrant original colors on inactive tabs, completely bypassing browser cache issues.

App Manager Tab Alignment & Styling. Centered the navigation tabs in the App Manager interface for a more premium, balanced look. Also forced local style overrides to ensure inactive tab icons render with their correct colorful theme in Light Mode before being clicked.

Task Scheduler Popup Readability. Fixed a readability issue with the "Suggested Command" code block in the Cron Jobs modal. The code block now dynamically adapts, displaying a readable light-themed background with dark text in Light Mode, while retaining the premium terminal-style dark background with green text in Dark Mode.

Private Redis Credentials Contrast. Addressed a critical contrast issue in both the User Panel (React) and Admin Panel (PHP) Domain Settings. The Redis Host, Port, and Password fields have been migrated to use responsive Bootstrap 5 semantic classes (bg-body-tertiary), ensuring they are perfectly legible and visually appealing in both Light and Dark modes.

Package Manager Ownership Clarity. Renamed and restyled the package management tabs to "Admin Owned Packages" and "Reseller Owned Packages" with distinct, intuitive icons to completely eliminate confusion regarding package ownership and creation rights. CATEGORY: CORE SYSTEM & PERFORMANCE

PHP OPcache Script Execution Bug. Resolved a critical bug in the system installation (install_php) and updater (update) scripts related to PHP OPcache configuration. This ensures that PHP caching mechanisms compile and reload flawlessly without causing any interruption during system updates or new installations. CATEGORY: API & BILLING INTEGRATION

WHMCS Module Suspension Trigger & Messaging. Fixed the automated account suspension trigger mechanism within the WHMCS module. Previously, suspension events were failing to correctly pass or display the exact suspension reason. The logic has been rewritten to accurately capture the WHMCS suspension reason message and seamlessly sync it with the BoostonCP backend, ensuring transparent communication to the end-user.

CORE SYSTEM & PERFORMANCE. MySQL & MariaDB Unlimited User Connection Quota (-1 Mapping): Resolved a critical database connection failure (MySQL Error 1226) where creating new databases under hosting packages with Unlimited (-1) connection limits caused MySQL/MariaDB to reject all user logins with "max_user_connections resource exceeded (-1)". Enforced strict input sanitization across database_manager.php, restore_db_users.php, user_manager.php, and CLI creation scripts to dynamically map negative package limits to 0, ensuring full compatibility with native MySQL and MariaDB unlimited user connection standards.

Theme Settings Layout Conflict. Restructured Appearance & Branding settings page into isolated containers (Admin Panel, User Panel, Default Domain Page) to resolve UI element overlapping.

Admin Dark Mode Logo Loading. Updated logo fetching logic to accurately resolve and render the dark mode header logo within the admin interface.

User Panel Logo Cache Fallback. Re-mapped dynamic backend fetching and frontend caching mechanisms to correctly apply custom client logos instead of defaulting to images/logo.png.
