UPDATE IS FINALLY HERE!

[f1eng]

It's weird my Spark still says 1.4.0 after the update?

I assume that you are using an iOS device?

I have been on 1.4.2 since yesterday on three Windows 10 PC and three Android phones but my iPad 3 still has 1.4.0 too.
This is likely because Apple hasn't cleared 1.4.2 for general release on the App Store yet.

If they are useful to you, here are direct links to 1.4.2 for Widows and OSX:

• http://www.devialet.com/softs/Spark-1.4.2.7.exe (Windows 10)
  
• http://www.devialet.com/softs/Spark-1.4.2.7.dmg (OSX)
  

Thanks - but I only ever use my phone so will have to wait for that

Since Devialet issued the update on a Friday there is little chance that the iOS version will be approved for distribution before Monday.
