+## 2018-04-05: 2018q1 release
+
+This release covers everything from the 2017q4 release on 2018-01-07 and has been
+tested with avr-gcc v7.2.0 and arm-none-eabi-gcc 2017q4 from Arm.
+
+Breaking changes:
+
+- No breaking changes.
+
+Major features:
+
+- ADC implementation for STM32F0
+- Block device interface and implementations
+- CMake wrapper generator
+- STM32L4 PLL configuration
+
+Major fixes:
+
+- Better Python 2/3 compatibility
+- Fix HD44780 timing
+- Fix AMSYS5915 sensor readings computation
+
+Known bugs:
+
+- xpcc may generate separate IRQ handlers for shared interrupts. See [#88][].
+- GPIO `connect` on STM32F1 is still broken. See [#178][] for discussion.
+  The API from MODM will not be backported to xpcc however.
+- STM32F107 does not compile due to the HAL trying to remap USB. See [#268][].
+- SCons build system emits multiple non-critical warnings. See [#286][].
+- avr-gcc 7 complains about dynamic initialization put into program memory area. See [#314][].
+- Template encoding issues on Windows. See [#345][].
+
+New development board targets:
+
+- STM32F030F4P6 demo board as `stm32f030f4p6_demo_board`
+
+New device drivers:
+
+- SPI Flash SST block device
+- Memory block device
+- File block device (hosted)
+- Mirrored block device

+
+#### 2018-04-05: Implement STM32L4 PLL configuration
+
+PR [#346][] -> [270d578][] with **medium-impact** on STM32L4 targets.  
+Tested in hardware by [@chris-durand][].
+
+#### 2018-01-30: CMake wrapper generator
+
+Basic support for generating CMake projects files.
+
+PR [#344][] -> [3490430][].
+
+#### 2018-01-28: Add STM32F030F4P6 demo board

+PR [#341][] -> [00ad2da][].  
+Tested in hardware by [@rleh][].
+
+#### 2018-01-28: Fix Uart7 and Uart8
+
+PR [#340][] -> [95233ba][] with low-impact on STM32 targets.  
+Tested in hardware by [@chris-durand][].
+
+#### 2018-01-28: Fixes for AMSYS5915 driver
+
+PR [#339][] -> [4656fd4][] with low-impact on AMSYS5915 driver.  
+Tested in hardware by [@chris-durand][].
+
+#### 2018-01-20: Fix timing in HD44780 driver

+
+#### 2018-01-14: Add a block device interface and several drivers
+
+Drivers to store data in a SPI SST flash `xpcc::BdSpiFlash`, to store data in a
+file (on hosted) `xpcc::BdFile` and to store data in RAM (for testing purposes)
+`xpcc::BdHeap` are included.
+Additionally, `xpcc::BdMirror` is a virtual block device that behaves like
+RAID1 devices.
