Hi All,
The wording for 20th September is confusing.
I have plugged a B2 version card into a B2 1TB unit and run 'Web Upgrade' on it. The version is now showing as 'B2 Sep 20 2021'. This is not a B2 SD model as it has a 1TB HDD fitted. However the B2 software has been updated but the following points are valid.
The 'Get Librespot' function is not present in the 'Advanced' menu.
The 'Get Ethernet' function is not present in the 'Advanced' menu.
The B2 software runs on the Linux kernel, which runs and manages the 'core' of the B2, memory, disk and USB management to name a few.
So these differences are possibly there because the 'B2B' software runs on Linux 4.19 whereas 'B2' software runs on older Linux 3.12. 3.12 was desupported in May 2017 which means that any current development work (software and drivers for example) will not be back-ported to this version.
Linux 4.19 is still supported, with a desupport date of December 2024, so this version is still current, although development of this release will be starting to wind down because Linux 5 was released in March 2019. The current long term supported version is Linux 5.10 so that might be the next major upgrade but only Martin will know that.
Regards,
Peter.
