Jolla Tablet Bluetooth class - downgrade or typo?

Currently, Jolla Tablet official specs are showing Bluetooth class 3.0

It's in contradiction with earlier info mentioning Bluetooth 4.0, shared on several ways ( TJC, Indiegogo, email from Jolla), so asking is this an uninformed downgrade to the specs, or is there just a typo in the specs page?

Edit:

1st, Bluetooth class is actually given as a single number, being either 1,2 or 3. Class is there for range, class 3 having max 1m, class 2 working on range of 5-10m. Most common in mobile devices is class 2

2nd, Bluetooth version is given as number and one digit, added by optional features, and it could be

  • Bluetooth 2.0 (data transfer rate 1Mbs)
  • Bluetooth 2.0 EDR (data transfer rate 3Mbs)
  • Bluetooth 3.0 (data transfer rate 3Mbs)
  • Bluetooth 3.0 HS (data transfer rate 24Mbs)
  • Bluetooth 4.0 / Bluetooth Smart (data transfer rate 24Mbs, support for Low Energy protocols)

Bluetooth 4.0 device can have dual mode (most smartphones) or single mode (majority of heart rate monitors etc). Dual mode enables connection to one LE device an one other Bt device, for example using a heart rate monitor and streaming music at the same time. LE mode is a software feature, and is (so far) missing for example on Jolla Phone, informing current official specs "Bluetooth 4.0 EDR HS"

3rd, there are protocols supported on software level, for example OBEX (objects), PPP (IP datagrams), A2DP (audio) etc.

In full, Bluetooth support could be informed including the version (core features), optional features (EDR/HS/LE), class (1,2,3) and all the supported protocols. Current Bluetooth Class 3.0 is very misleading
