• Atomic traffic statistics collection. Replaced read-modify-write logic with atomic SQL increments (Capsule::raw) in StatisticsSaveTraffic(), eliminating race conditions and traffic data loss during concurrent WHMCS cron jobs and metric queries.
• WHMCS Usage Billing MetricProvider fix. Resolved zero-traffic reporting so that Usage(0.0) is reliably returned when usage is 0 GB, preventing "No usage data" statuses in WHMCS.
• Unified interface reset action. Removed redundant resetConnection action and button, standardizing on a single, clean Reset VPN Interface button across admin and client interfaces.
• Admin API connection timeout. Enforced a strict 15-second timeout on router status checks with offline circuit breaker, eliminating admin panel hangs on unreachable Mikrotik routers.
• Guzzle HTTP Client integration. Migrated all external API and license verification requests from legacy cURL to \GuzzleHttp\Client with exponential backoff and retry mechanism.
• ionCube 15 & PHP 8.2+ architectural upgrade. Transitioned hooks.php to an unencoded lightweight bootstrap delegating logic to lib/puqMikrotikVPNHooks.php for seamless ionCube 15 compatibility.
• Automated usage cleanup on termination. Local usage statistics in puqMikrotikVPN_statistics are now automatically purged when a service is terminated.
• Enhanced Client Area UI. Integrated standard PUQ client area UI toolkit with header.tpl, dynamic copy-to-clipboard buttons, toast notifications, CSRF protection, and streamlined responsive layout.
• Legacy configuration fallback. Added transparent backward compatibility for products migrating from older configuration slots (configoption2..11).
• Comprehensive localization. Standardized translation strings across all 26 supported languages with safe typographic apostrophes and full Ukrainian language support.

1. Full support for the latest RouterOS 7.21.4. The module has been verified end-to-end against the newest Mikrotik firmware, so you can confidently run your VPN services on up-to-date, secure routers.

2. Rock-solid router communication. Connections to your Mikrotik devices are now even more reliable — requests that could previously stall on certain firmware versions complete instantly, keeping provisioning and management fast and dependable.

3. Stay current with peace of mind. Whether you are deploying brand-new routers or upgrading existing ones to the latest RouterOS, your VPN automation keeps working smoothly out of the box.

4. PHP 7.4 support is back. The module runs flawlessly on PHP 7.4 once again, so customers on established hosting stacks can keep their proven setup without rushing a server upgrade. We will continue to support PHP 7.4 for as long as it remains technically possible.

• Improved stability across the WHMCS admin area. Rare page-loading errors that could appear on some admin screens (for example when opening a support ticket on installations with non-standard file layouts, symlinks or custom hosting paths) have been eliminated. The admin panel now loads smoothly in every environment.
• Greater compatibility with complex hosting setups. The module is now fully resilient to WHMCS installations using symlinked directories, multi-domain hosting and custom include paths.
• Smoother day-to-day operation for administrators. Fewer interruptions, no unexpected "Oops!" pages, and a more predictable experience when working with tickets, clients and services — so your team can focus on customers, not on troubleshooting.
