+## 2017-07-02: 2017q2 release
+
+This release covers everything from the 2017q1 release on 2017-04-05 and has been
+tested with avr-gcc v5.4.0 from Atmel and arm-none-eabi-gcc 2017q2 from ARM.
+
+Breaking changes:
+
+- No breaking changes
+
+Major features:
+
+- STM32L4 target support and drivers
+- Improve assert implementation and make use of them
+
+Major fixes:
+
+- Fix issues and warnings in release tests
+- Fix wrong `ns_per_loop` rounding in board definitions
+
+Known bugs:
+
+GPIO `connect` on STM32F1 is still broken. See [#178][] for discussion.
+The API from MODM will not be backported to xpcc however.
+
+New development board targets:
+
+- NUCLEO-L476RG as `nucleo_l476rg`
+- STM32L476G-DISCO as `stm32l476_discovery`
+
+New device drivers:
+
+- DS1302
+- TCS3472X
+
+Many thanks to all our contributors.
+A special shoutout to first timers (🎉🎊):
