Version 3.4.5 of the MultiSense ROS driver for the CRL MultiSense line of products was released on 10/20/2015.
This version of the driver changes image encoding types from 8UC1/16UC1 to mono8/mono16 data formats. In some versions of ROS these types are not equivalent which was causing processing and display issues for some customers. Thanks to Wenfan Shi and Ryohei Ueda for reporting this issue on BitBucket:
More information about these changes can be found in the ROS driver documentation.
