Redaction: Deterministic Masking Values Differ
MarkLogic 9.0-4 introduced support for salting in the generation of masking values by the mask-deterministic redaction function. This means the same text redacted with mask-deterministic in earlier versions of MarkLogic will not produce the same masking value by default when redacted using MarkLogic 9.0-4.
To preserve the previous behavior, modify your mask-deterministic rules to set the salt and extend-salt options to an empty value.
For more details, see mask-deterministic in the Application Developer's Guide.
