Release of BlueZ 5.26
This release is for the most part a bug-fix release with fixes in A2DP and OBEX related functionality, but there’s also an added features for get/set reports for HID over GATT as well as Phonebook Access Profile 1.2 support
On the Android side the 5.0 (Lollipop) support is now starting to be fairly mature with full PTS test runs either with PTS 5.3 or 6.0.
The Bluetooth 4.2 specification went public in early December and BlueZ 5.26 is the first release with support for its features. Perhaps the most notable one of these is Low Energy Secure Connections which will require a 3.19 or newer kernel. This feature brings LE pairing to the same level of security as it has been for BR/EDR. LE SC also brings along with it so-called cross-transport pairing, which means that you only need to pair once over LE or BR/EDR to get the necessary keys for both transports between two dual-mode devices.
