[Unreleased]

Fixed

• Limited routine CI image builds to linux/amd64 so normal push validation no longer fails on the currently unstable ARM64 test path.
• Updated Trivy workflow steps to aquasecurity/trivy-action@0.35.0 and guarded SARIF uploads so missing output files no longer break the workflow.
• Stopped the maintenance workflow from opening duplicate automated security audit issues when an equivalent issue is already open.

Changed

• Updated audiobookshelf from 2.30.0 to 2.33.0 across the build, docs, and branding to pick up the latest upstream fixes.

  • Updated docker-compose.yml FILE__ prefix mapping
  • Updated S6 init-secrets script to export correct variable name
  • Action Required: Regenerate secrets with make secrets-generate

🔐 Secret Management Overhaul

• Fixed JWT_SECRET_KEY loading: Container now correctly loads secrets from Docker secrets
• Removed unused secrets: Eliminated API_KEY, DB_USER, DB_PASSWORD (not used by audiobookshelf)
• Updated Makefile: secrets-generate now creates only JWT_SECRET_KEY + SESSION_SECRET
• Comprehensive .env.example: Complete rewrite with 278 lines covering all 50+ audiobookshelf ENVs
  • 9 categorized sections (Container, Filesystem, Network, Security, etc.)

  • DL3059 ignored (Multi-stage build structure requires multiple RUN commands)
  • DL4006 ignored (Alpine shell compatibility)
• Enhanced greetings.yml: Added pre-merge checklist for contributors
• Removed docker-compose version warnings: Eliminated obsolete version fields from all compose files

🔧 S6 Overlay v3 Service Architecture

• Fixed duplicate branding: Suppressed LinuxServer.io "CUSTOM BUILD" ASCII art
  • Created empty init-adduser/branding file to override baseimage default
  • Now only displays custom Mildman1848 branding
