From f991b0e35ad1bd3b999c70e68c518bae91bd36a6 Mon Sep 17 00:00:00 2001
From: Sylvain Miermont <smiermont@semtech.com>
Date: Fri, 28 Mar 2014 16:58:48 +0100
Subject: v1.3.0

- Added TX power management.
- Added full support for SX1301 reference board.
- Changed build system with configuration for multiple chip/radio/band support.
- SX125x bandwidth set to 1MHz by default (was 800 kHz).
- Solved warnings with 64b integer printf when compiling on x86_64.
- Renamed helper programs to reduce the concentrator vs. gateway confusion.
