[1.1.19] - 2025-09-27

Process Manager Migration: Complete migration from supervisor to s6-overlay
BREAKING: Removed supervisor completely due to multiple security vulnerabilities (CVE-2023-27482)
Implemented s6-overlay v3 as secure container-native process supervisor
Eliminated Python runtime dependency reducing attack surface by ~50MB
Enhanced container lifecycle management with proper PID 1 handling
Improved signal forwarding and zombie process reaping
Container now exits properly when services fail (better health reporting)
Docker Image Hardening: Addressed additional security vulnerabilities
Replaced unzip with p7zip to eliminate CVE-2008-0888 vulnerability
Updated base Alpine Linux image to alpine3.22 for latest security patches
Enhanced container security posture with minimal attack surface
Improved archive handling capabilities with more robust tooling

Application Architecture: Restructured core components for better maintainability
Moved IndexerCache class from main index.php to dedicated endpoint .indexer_files/php/IndexerCache.php
Relocated URLRouter class from main index.php to dedicated endpoint .indexer_files/php/URLRouter.php
Improved code organization with cleaner separation of concerns
Enhanced modularity for easier maintenance and debugging
Page Title Display: Improved contextual title generation
Changed title format from full path display (Index of /example/folder) to simplified folder name (folder)
Added special handling for root folder indexing displaying "5q12 Indexer" as title
Enhanced user experience with cleaner, more focused page titles
Reduced visual clutter in browser tabs and bookmarks

URL Routing Consistency: Resolved manual URL generation issues across interface components
Fixed "Close" button on share popups to use proper URL routing instead of manual generation
Corrected "options-menu" button URL handling for consistent navigation
Fixed all options in "options-dropdown" to utilize centralized URL routing system
Improved URL consistency and reduced potential for broken links

Docker Environment Integration: Comprehensive configuration management through environment variables
Added support for config.json configuration via Docker Compose environment variables
New environment variable support includes:
INDEXER_ACCESS_URL: Set application base URL
INDEXER_CACHE_TYPE: Configure caching mechanism (json)
INDEXER_ICON_TYPE: Set icon display mode (minimal)
INDEXER_DISABLE_FILE_DOWNLOADS: Control file download functionality
INDEXER_DISABLE_FOLDER_DOWNLOADS: Control folder download functionality
INDEXER_INDEX_HIDDEN: Toggle hidden file indexing
INDEXER_INDEX_ALL: Enable comprehensive file indexing
INDEXER_DENY_LIST: Specify excluded paths and patterns
INDEXER_ALLOW_LIST: Specify included paths and patterns
INDEXER_INDEX_FILETYPE_PHP: Control PHP file indexing
INDEXER_VIEW_FILETYPE_JS: Enable JavaScript file viewing
INDEXER_INDEX_FILETYPE_MD: Control Markdown file indexing
INDEXER_VIEW_FILETYPE_MD: Enable Markdown file viewing
Enhanced Docker deployment flexibility with comprehensive configuration options
Simplified container orchestration with environment-based configuration

S6-Overlay Process Management: Optimized container startup and resource usage
Faster container startup compared to supervisor-based images
Reduced memory footprint with elimination of Python runtime
More efficient process supervision with C-based s6 implementation
Better resource utilization in containerized environments
PHP Endpoint Management: Optimized file handling for containerized deployments
Enhanced initialization script with special handling for .indexer_files/php/ directory
Automatic recreation of PHP files ensures up-to-date functionality across container restarts
Improved reliability of core application components in Docker environments
Reduced potential for stale file issues in containerized deployments

S6-Overlay Service Architecture: Modern container-native process supervision
Implemented dedicated s6 service definitions for nginx and php-fpm
Added comprehensive initialization service with enhanced configuration merging
Proper service dependency management ensuring correct startup order
Container-native signal handling and graceful shutdown procedures
URL Router Architecture: Centralized URL handling system
Eliminated manual URL construction throughout application
Improved consistency in link generation across all interface components
Enhanced maintainability with single point of URL logic control
Better support for future URL structure modifications
Container Optimization: Streamlined Docker image management
Migrated from supervisord.conf to s6-overlay service definitions
Enhanced entrypoint script logic now integrated into s6 initialization service
Better integration between host configuration and container runtime
Enhanced debugging capabilities for containerized deployments
Optimized startup performance with efficient file system operations

Breaking Change: Containers built with this version no longer use supervisor
Security Improvement: Eliminated multiple CVEs associated with supervisor package
Performance Gain: Reduced container size and improved startup times
Industry Standard: Now using s6-overlay (same as LinuxServer.io, Home Assistant)
Compatibility: All existing functionality preserved during process manager migration

Configuration Migration: Seamless transition for existing deployments
All existing configurations remain fully functional
New environment variable configuration supplements rather than replaces existing methods
Docker deployments maintain compatibility with previous image versions (except process manager)
Non-Docker deployments unaffected by containerization improvements
API Compatibility: No changes to user-facing functionality
All web interface features remain identical
File browsing, downloading, and viewing functionality unchanged
URL structure and routing behavior preserved
