    "\n",
    "### What is it?\n",
    "v0.7.5 introduces a **completely new Docker Hooks System** that lets you inject custom Python functions at 8 key points in the crawling pipeline. This gives you full control over:\n",
    "- Authentication setup\n",
    "- Performance optimization\n",
    "- Content processing\n",
    "- Custom behavior at each stage\n",
    "\n",
    "### Three Ways to Use Docker Hooks\n",
    "\n",
    "The Docker Hooks System offers three approaches, all part of this new feature:\n",
    "\n",
    "1. **String-based hooks** - Write hooks as strings for REST API\n",
    "2. **Using `hooks_to_string()` utility** - Convert Python functions to strings\n",
    "3. **Docker Client auto-conversion** - Pass functions directly (most convenient)\n",
    "\n",
    "All three approaches are NEW in v0.7.5!"

    "### Problem\n",
    "When crawling HTTPS sites, internal links sometimes get downgraded to HTTP, breaking authentication and causing security warnings.\n",

    "### Solution  \n",
    "The new `preserve_https_for_internal_links=True` parameter maintains HTTPS protocol for all internal links."
