Version

Release 2.0.0

Major Features and Improvements

Added support for QUIC and HTTP/3 on newer servers. This will allow the newest Nginx version to be installed/updated from the Nginx repo.

v1.3.12 — 2026-04-14

Per-User Cache Purge Fix (Critical)

Fixed grep missing -E flag in per-user cache purge command. The domain pattern uses | as OR separator between multiple domains (e.g. domain.com|www.domain.com|mail.domain.com), but basic grep treats | as a literal character. The purge searched for the entire string including the pipe characters instead of matching any of the individual domains. Changed grep -qa to grep -qaE to enable extended regex.
Added grep -a flag for binary-safe matching. Nginx cache files contain a binary header (~336 bytes of null bytes) before the cache key. Without -a, grep may stop reading at null bytes and never reach the domain name stored in the cache key.
Increased cache file header read from head -c 512 to head -c 768 to accommodate the binary header plus longer URL cache keys.

wsad Service — PID File Path

Updated PID file path from /var/run/wsad.pid to /run/wsad.pid across all files to resolve the systemd warning: "PIDFile= references a path below legacy directory /var/run/". Affected files: wsad.service, wsad.pl, wsa.php, module_handling.php, post_update.php, update.sh, uninstall.sh, install/services/wsad.

v1.3.6 — 2026-04-10

Cache Categories Consolidation

Reduced Nginx cache categories from 6 to 3 for simpler configuration and smaller vhost files:
- Dynamic — Unchanged
- JS/CSS — Unchanged
- Images/Fonts — Merged from the former Images, Fonts, Static files and Archives/Media/Documents categories
Files previously cached under Static files (json, xml, rss, atom) and Archives/Media/Documents (zip, mp4, pdf, etc.) are no longer cached.
Automatic migration of all existing user and global configuration files via post_update.php (v1.3.0 block).

Cache Purge Performance

Full cache purge (Purge_All_Cache / Clear_Cache(null)): Replaced find | xargs rm with atomic directory rename + recreate. Purge is now near-instant regardless of file count.
Per-user cache purge (Clear_Cache($users)): Replaced grep -r (full file read) with head -c 512 (header-only read) using parallel workers (xargs -P). Added domain name sanitization to prevent shell injection.

Auto-Update Reliability

Fixed Send_Curl_Request in activation.php: removed stray echo 'error!!!', added CURLOPT_CONNECTTIMEOUT (10s), increased CURLOPT_TIMEOUT to 15s for heartbeats and 120s for update downloads, added CA bundle path fallback for older AlmaLinux/CentOS systems.
Fixed Send_Curl_Version in auto_update.php with same timeout and CA bundle improvements.
Fixed enable_auto_update check defaulting to disabled when the SQLite option was never initialized.
Added checkModule case to cron Run_Job() switch statement (was defined but never executed).
Added archive integrity validation before extraction: file size check, tar tzf test, and post-extraction verification of update.sh.
Fixed start_action_info function missing from update.sh (was defined only in install.sh).
Added update logging to /var/log/wsa/update.log and archive validation in update.sh.

wsad Service — Migration to systemd

New wsad.service systemd unit file with Type=forking, Restart=on-failure, and KillMode=process.
PID file path updated from /var/run/wsad.pid to /run/wsad.pid across all files (wsad.pl, wsad.service, PHP and shell scripts).
Automatic migration from SysV init script to systemd via post_update.php (v1.3.5 block): stops old service, removes init script, installs unit file, enables and starts via systemctl.
Updated install.sh and uninstall.sh to use systemd for fresh installs and clean uninstalls.
Fixed create_command() in services.php: replaced broken comparison ($environement == '7') with file_exists('/bin/systemctl') detection. All services (nginx, httpd, wsad) now correctly use systemctl on AlmaLinux 7/8/9/10.
Fixed start_on_boot() in services.php with same systemd detection logic.
Updated Check_Wsad_Service() in wsa.php to use systemctl is-active and systemctl restart instead of legacy service commands.
Added ghost process cleanup (kill stale wsad.pl + PID file removal) in module Enable and Disable methods.

UI Modernization

cPanel interface: Complete CSS rewrite with design tokens (CSS variables), card-based layout, rounded corners, soft shadows, modern toggle switches, pill-shaped status badges, smooth micro-transitions, refined color palette, custom scrollbar styling, and backdrop blur on popup overlay.
WHM interface: Matching CSS rewrite with same design token system, modernized menu items with hover animations, refined tables with rounded corners, dark-themed console output, gradient resource usage bars, and improved tab navigation.
No HTML template changes required — all styling is CSS-only for zero regression risk.

Housekeeping

Removed unused template advance_cache_static.tpl.
Added advance_cache_imagesfonts.tpl template for the new Images/Fonts cache tab.
Updated English (en.php, whm-en.php) and French (fr.php) language files with new category labels.
