Release 2.0.7

=============



* Fix a bug in the assembly sequence that starts the Nordic bootloader. With

  GCC, a MOV instruction was getting converted into an ADDS, which came with

  an unwanted side-effect of updating the XPSR. We relocated the offending MOV

  instruction such that it would not affect a conditional branch statement.

  This would show only with GCC, and when jumping to the bootloader while in

  handler mode.



* Fix hardfaults generated from the handling of Radio Notification events.

  Radio notification events are interrupts generated at very high priority.

  They have the potential to pre-empt other interrupt handling, causing race

  conditions when interrupted handlers were involved in calling into BLE_API.

  Radio-notification events should defer their callback handling to low-

  priority handlers through the use of Tickers or Timeouts.



* Introduce watchdog header file from Nordic SDK 8.1.



* Update license headers to reflect the latest licenses from Nordic.
