Hi,
This is the list of third party modules that you are using and which is available in the odoo apps store. The authors of the module has released an updated version of the module and in your odoo instance, it is still old version.
Suppose if you download a module with version 15.0.1.0.0 and installed in your db, and later the author made some updates, which can be fixes or improvements and released next version 15.0.2.0.0 in the apps, so in your odoo instance, the version is old, so depending on the updates done by the author, you have to use the latest of those modules in your instance.
Go to apps, download the module, add it to your addons path, restart service and upgrade the module.
Thanks
