Load Tester 6.1 adds the ability to perform file uploads within real-browser testcases. See the link for instructions on using this new feature.
The release updates support for Chrome to include versions 33-36.
In addition, we have improved the user distribution algorithm specifically for real-browser tests. The real-browser replay logs now include annotations about datasource usage, so you can easily see, for example, which login was used from a dataset when an error occurred. See the change log for the additional bug fixes contained in the release.
