B2 Settings->Web Upgrade
BB1 Settings & Tools->Maintenance->Web Upgrade

Details about the upgrade are published first on the UK site here

Here are the most recent changes

10th March 2022

This web upgrade for B2 and B2B prepares your B2 for use with the new App. It also includes all the recent changes in the experimental releases. Apple Superdrive (B2B only), more presets, improved CD playback through Sonos, variable duration record from radio.

2nd March 2022

The experimental software (left panel) now contains an option in Settings->Maintenance->Advanced to install a driver for the Apple Superdrive CD mechanism. Thanks to Struan for all the heavy lifting.
You can just plug the Apple Superdrive into a B2 USB port and use that instead of the internal CD mechanism.
Other changes in the experimental software include support for the next generation app - to be released in the new few weeks.

22nd October 2021

B2B now has a simple record from radio function.
Play the station on the local (wired) loudspeakers and press REC on the remote.
It will stop when you press stop or after one hour.
The recordings are labeled with the date and time and the radio station is the "artist" so they are easy to find in the web UI.

15th October 2021

This upgrade for b2 and b2b fixes a problem with the artist item menu in the v3 mobile UI.
It also includes some diagnostics for our internal use.

30th September 2021

This upgrade for b2b selects wired speakers when Forget Sonos selected.

20th September 2021

This upgrade is for B2s running the 'b2 xxxx' version software and has the recent b2b improvements.

17th September 2021

This upgrade for b2b fixes an occasional problem with the Musicbrainz server causing some CDs to be unrecognised and ejected. Also fixes erroneous duplicated album display on the web UI immediately after ripping. Thanks to Ian L. for his help with this.

7th September 2021

This upgrade for b2b quietens CD playback. Play track in the album menu now plays to chosen zone

2nd August 2021

This upgrade for B2B improves startup on Sonos CD play and adds ~ to list of characters that can be entered on the remote/rotary. You can find it after # or on the 1 button of the remote.

28th July 2021

This upgrade for B2B adds track names and album art to Sonos CD play. The art will show up on the web UI and the Sonos App - though not currently on the Brennan App.

20th July 2021

New feature for B2. Create a playlist called "Blacklist" and anything that appears in that list will not play during random play. You can specify tracks, albums or artists. This upgrade is only for B2B software - original B2 and BB1 to follow.

13th July 2021

Exciting experimental software that lets you play CDs through Sonos speakers.
Pick the zone, insert a CD, wait for it to read the contents and press play.
(Or if there is already a CD inserted press the CD button on the remote or use the CD menu.)
CDs are played losslessly.
Its under development so it doesn't display track names yet and the web UI doesn't know about it yet. You may encounter the odd UI wrinkle - let us know any issues.
As far as I know this is a world first - there is no other device that lets you "stream" CDs.
(Though to be fair Sonos sell the Sonos Port at £399 to stream any audio source - though I'm not sure if they use MP3).
Thanks to the Brennan owners who asked for this - I worked on it for a few days and decided it was impossible - then had a brainwave.

1st March 2021

This upgrade for BB1 and B2 includes 'Stereo Pairs' improvements and the front panel option for the B2 - BB1 to follow. And a couple of bug fixes since 25th.
The B2 now sorts Sonos zones alphabetically so it may be a good idea to click Scan Sonos on the web UI (Settings) and then reload the web UI - just once so everything is in sync.
The BB1 code includes a fix for DAC support.
