This month, the team delivered stability improvements for the Audio Recording feature and prepared data migration to version 1.3.3 in the oat-sa/extension-tao-itemqti-pci repository. Key focus was ensuring the recording attempt counter resets correctly when navigating between items during an active recording, proper increment on new recordings, and implementing a migration to correctly apply recordsAttempts state for version 1.3.3. These changes reduce recording errors, improve user experience during item navigation, and ensure forward compatibility with 1.3.3 deployments.
