IPFS also has IPNS. IPNS allows you to use your peer id (that you get by running the daemon) as a name. So if your peed id is "A", you can point "A" to hash "123" and give "A" to the people you want to share the content with. If you now add a new thing and get the hash "456", you can update "A" to now point to that hash instead. That way, you can update the content seamlessly, without breaking things for other people.
