ReadyNAS OS hotfixes are used for issues that are critical in nature and we provide these fixes for all devices connected to the internet. Over the past year we have provided hotfixes for issues that were reported shortly after a release that can be resolved without service interruption.
Some examples of hot fixes that we have provided in the pasted were helping cases like the following:
Admin interface is offline
Critical security fixes
Not able to use ReadyCLOUD services
App developer utility fixes
Today we provide these hot fixes for all ReadyNAS connected to the internet. We have provided these hot fixes from the beginning of 2017. If you are an advanced user, you might have noticed the debian package "readynasos" with an appended "+#". This was showing that a hotfix was applied to your unit. Example: Hotfix 2 would display version 6.9.3+2 on the backend.
We have received some feedback regarding to when hotfixes are available and applied to your ReadyNAS. We are bringing some of this information to the surface to the admin interface. We will show you what firmware version (including the hot fix number) and will provide an alert to inform you that the hotfix has been applied.
Example reference to one of the hotfixes that we have applied in the past:
