SRT Version History & Compatibility

SRT is designed to be backwards compatible, so that new or upgraded products will be able to support SRT interactions with older ones. Note, however, that newer versions of SRT may have features unavailable on older ones.

Important

SRT versions 1.3.4 and earlier have a CSandUList array overflow vulnerability if there are many SRT connections. For more information, please refer to CVE-2019-15784.
