Thank you, @javimed. It's a great initiative to make the version placement dependent on the value of the is_latest_release variable.

However, we still need to include the version variable in some documents, for example:

• /user-manual/deployment-variables/deployment-variables-linux.rst
• /_templates/installations/basic/wazuh/deb/install_wazuh_manager.rst
• /_templates/installations/basic/wazuh/yum/install_wazuh_manager.rst

Please review and add the missing variables. Thanks!

Hi @javimed,

There are still files where it's necessary to add version variables, for example, the Wazuh with Splunk installation guide and the Elastic Stack upgrade guide. Thanks in advance!
