It’s been awhile since the last BlueZ release, but now we finally have another one out. Most of the fixes are LE (specifically GATT) related, however a some other areas are affected as well. Feature-wise, there’s a new MIDI plugin and support for using single-mode (LE-only) controllers that lack a public address (therefore necessitating the use of a static random identity address). E.g. any nRF5x controller running a MyNewt or Zephyr based firmware falls into this category.
