Please note:


While Sputnik Agent Firmware version 3.3.7.6 is not required for SputnikNet 3.3.7.6, we recommend that customers upgrade their routers to the latest firmware.


For customers running Sputnik Control Center:


To upgrade to Sputnik Control Center 3.3.7.6, first upgrade to 3.3.7.0 as described in the 3.3.7.0 change log; then follow these upgrade instructions.
