Change summary

The compute hashsum subcommand was deprecated in version v10.1.0, on 2023-05-18. It was made a hidden option, and invoking it evoked the warning "This command is deprecated. Use fastly compute hash-files instead.". It has also been removed from the reference documentation.

We're now at v13, in 2026, so I propose we remove the option now.

User Impact

An option that has been hidden, undocumented, and that issues a deprecation warning, for about 2.5 years and 3 major releases, is removed.

Users that still need to compute the hash value that fastly compute hashsum computed can do so using commonly-available tools, such as the sha512sum command in coreutils, the shasum -a 512 command on macOS, or the openssl sha512 command.

The `compute hashsum` subcommand was [deprecated] in version v10.1.0,
on 2023-05-18. It was made a hidden option, and invoking it evoked
the warning "This command is deprecated. Use `fastly compute hash-files`
instead.". It has also been removed from the [reference documentation].

We're now at v13, in 2026, and a reasonable amount of time has passed,
so I propose we remove the option now.
