What means "(deprecated)" for my bought assets?

Since Unity 5 there are some assets in my Asset Store downloads marked with “deprecated”.
Does that mean, that I can’t download them anymore at some specific date?
Or are the just not available in the store anymore, but I can still download it?
I don’t wanna lose my expensive bought assets.
Thanks for your help

It means “outdated”, “better methods exist”, “no longer considered best practice”, and perhaps most importantly, “will continue working for now but will likely break at some point in the near future”.
