Release Notes V2.7.1

Important

IP Audio Client V2.7 License: It is possible to install this new release of IP Audio Client onto a device that is running an un-licensed firmware, but once that is done it is not possible to go back to the unlicensed firmware, even if they are the same. i.e. If IPAC 2.7 is installed on an M400 SIP Opus 1.3.4 (which is unlicensed), the firmware will install, but it will not be possible to roll back to SIP Opus anymore. Another example: when updating firmware from previous IP Speaker versions (e.g. IP Speaker V2.6.2 or previous) it will be possible to update but not to roll back.
