Release of BlueZ 5.54 (and 5.53)

This is a combined announcement for BlueZ 5.53 and 5.54 – due to some technical issues the website couldn’t be updated until now.

These releases have numerous fixes to A2DP, HoGP, UUID matching and advertisement unregistration (for peripheral/broadcaster role).

Among new features are support for a blocked keys database, initial pieces for the Enhanced ATT bearer (EATT) from Bluetooth 5.2, a new just-works repairing policy (which requires the not-yet-released 5.7 kernel), and a new MTU auto-tuning option for AVDTP.
