Ultra Messaging version 6.12.1 (6.12 HotFix 1) has been released to shipping and is available immediately to all licensed customers.
This release includes the following key improvements:
UM now supports the Microsoft .NET framework on 64-bit Linux.
The Network Socket Busy Waiting feature can be used to prevent a context or XSP thread from sleeping while waiting for network events, such as received packets. This can reduce latency and especially latency outliers (jitter).
The dependency between UM and the OpenSSL libraries is now optional. If the libraries are not used, then they do not need to be present on the system.
