Valkey 8.0.11 deprecates sanitize-dump-payload, now a no-op

The release notes for Valkey 8.0.11, dated August 31, 2026, announce multiple security and bug fixes, alongside the deprecation of the `sanitize-dump-payload` option. This option, previously used to validate listpack payloads during RDB load and RESTORE operations, is now a no-op. Instead, the system always performs deep validation of listpack payloads, addressing potential deferred assertion crashes.

Operators should verify whether their configurations or workflows rely on the `sanitize-dump-payload` option. Since it no longer performs any action, configurations using this option may need adjustment to ensure intended behavior. Additionally, systems dependent on older validation mechanisms should be tested to confirm compatibility with the new deep validation approach. This change reflects a broader trend in software projects to deprecate legacy options in favor of more robust default behaviors, but it underscores the importance of reviewing configuration dependencies before upgrading.
