Updated disclosure control guidance

We have recently made some updates to our disclosure control guidance. This is important for both researchers requesting release of outputs and those who review them. We have made the following changes, which are summarised in more detail below:

• Requiring rounding of counts in addition to suppression of low counts
• Increasing the small number suppression threshold to 7
• Encouraging release of underlying data earlier in the analysis pipeline
• A new checklist for requesting a release
• Updated recommendations for release of log files
• More detail on allowed file types
