+## [0.3.3] - 2022-09-14
+### Fixed
+- SFProcessTurn causing CREATE_FAILURE and stack rollback. This was caused by the Sept 10 release of the FFMPEG v5.1.1 distribution which had a larger size than the earlier version, resulting in the FFMPEG Lamba Layer exceeding the max size allowed by the Lambda service. To avoid this issue, the main stack CloudFormation parameter `ffmpegDownloadUrl` now defaults to the v4.4 distribution instead of 'latest'.
+- Reduce Lambda function failure rate when processing very large audio files:
+  - Increase multiple PCA server lambda function memory allocation to make functions run faster, and increase timeouts to reduce liklihood of timeouts when processing large audio files.
+  - Increase empheral storage for 'StartTranscribeJob' lambda to accomodate S3 download and temp storage of large audio files.
+
 ## [0.3.2] - 2022-08-24
 ### Fixed
 - PCA Workflow failure with KMS encrypted recordings caused by the new `SFPostCTRProcessing` Lambda function role not included in KMS Key policy. Function role now included in the `RolesForKMSKey` output.
