With the upcoming depreciation of TLS 1.0 and 1.1 on 31st October, do we expect any of the core Umbraco packages to be affected, I'm thinking around the file providers for Blob on V7 and V8?

I don't expect very little, if anything, to break really. It would have done so already over the years as most servers have long stopped accepting older TLS version connections. If I recall correctly, this can only start failing if the origin server (where your Umbraco install lives) is still configured to start with a TLS 1.0/1.1 connection. If you run your own server, then yeah, it might stop connecting (but it probably would have had errors for years already with anything it tried to connect to outside of that server). For the blob storage provider for v7 specifically, the potential problem was already fixed in 2021 - https://github.com/umbraco-community/UmbracoFileSystemProviders.Azure/commit/1109ca6138b656791f8bb6d52a8c025e88204e1b This is forcing all outgoing connections to TLS 1.2 first (it still falls back to 1.1/1.0 if the remote doesn't support 1.2). You can see in the discussion that this has helped a few people who ran into this problem at the time https://github.com/umbraco-community/UmbracoFileSystemProviders.Azure/pull/187

Try telling that to clients 😂 Thanks for those links, hopefully it's a simply fix should anything happen 🙂

I am not very scared to be honest. Just as long as you're not hosting your own ancient servers you should be fine.
