We need to update the redirects.js file with the files removed, the ones added and the necessary redirections. For example

newUrls['4.8'] = [
  ...
  '/user-manual/wazuh-dashboard/management.html',
];

removedUrls['4.8'] = [
  ...
  '/user-manual/wazuh-dashboard/settings.html'.
];

/* Redirections from 4.7 to 4.8  */

redirections.push(
  {
    'target': ['4.7=>4.8', '4.8=>4.7'],
    '4.7': '/user-manual/wazuh-dashboard/settings.html',
    '4.8': '/user-manual/wazuh-dashboard/management.html',
  },
  ...

CentOS endpoint text with an Ubuntu endpoint image

We should highlight 11.2.1 on the right instead, since next text and image are about 11.2.1.

text says Threat hunting while new image shows Discover.

Text says "the various cloud provider modules" while the image highlights only a partial selection of some of the cloud security modules available

Highlighting test 3003's result would be a plus

Maybe if we shrinked the time range bars would spread along the graph

Having multiple connections, in varied connection and update status, besides the starred one, would improve the image.
