Archive Operating System (AOS 7.4.1) Updates

More Reliable Matching Across Complex Content

Previous versions of the redaction engine could encounter failures when the text selected for redaction contained unexpected formatting, such as HTML entities, emoticons, punctuation, Unicode variations, or other characters that don’t always appear the way you’d expect in raw email data. In some cases, these characters caused redaction operations to fail entirely, and could even prevent exports to PDF from completing.

AOS 7.4.1 introduces a major rewrite of the redaction engine. Matching now occurs against normalized content, which means the system intelligently resolves formatting and encoding differences before attempting to find and redact a match. Equivalent text representations, whether they differ in case, accents, character width, or punctuation, are now detected and handled correctly.

The result: fewer failed redactions, more consistent behavior in complex HTML emails, and no more export failures caused by unexpected characters in selected text.

Supported Normalization Behaviors

The new engine handles a wide range of text variations automatically:

These normalizations happen automatically, no configuration required. Whether you’re redacting names, account numbers, or sensitive phrases from a wide variety of email sources, the engine will find and handle them consistently.

Migration Reliability Improvements (6.x to 7.x)

Customers migrating from the 6.x platform to AOS 7 will benefit from improved reliability throughout the migration process. Multiple issues that could interrupt or derail the migration, particularly in edge cases involving data structure differences between versions, have been identified and resolved. As our customer base continues to move to AOS 7, we remain committed to making that transition as smooth and dependable as possible.

Remote Backup Stability

Several issues in the remote backup process have been addressed to improve overall stability and reduce the likelihood of backup failures. Reliable backups are foundational to any compliance-grade archive deployment, and these fixes bring the remote backup process in line with the reliability standards you expect from Intradyn.

Federated Message Retrieval: Permission Denied Errors Resolved

Some customers experienced unexpected “permission denied” errors when retrieving messages in federated environments. The underlying issues causing these errors have been identified and fixed, restoring reliable access to federated message content.

This release reflects our ongoing commitment to making Intradyn’s platform more robust, more accurate, and ready for the full complexity of real-world communications data. We encourage all AOS 7 customers to upgrade to 7.4.1 to take advantage of the improved redaction engine and the stability improvements throughout.
