+## 2021-07-01: 2021q2 release
+
+This release covers everything from 2021-04-01 and has been tested with avr-gcc
+v10.1.0 from Upstream and arm-none-eabi-gcc 2020q4 from Arm.
+
+Breaking changes:
+
+- TinyUSB updated from v0.8.0 to v0.10.1 with breaking changes to their APIs.
+- FreeRTOS configuration must be done by the user via the headers
+  `<FreeRTOSConfigLocal.h>` and `<FreeRTOSIPConfigLocal.h>`.
+- `modm::GraphicDisplay` API changed due to change in color management.
+- New color types and API.
+- New CMake build system has different API without top-level Makefile.
+
+Features:
+
+- STM32L0 support.
+- Real-Time Transport (RTT) support via OpenOCD v0.11.
+- FDCAN driver for STM32G4 (only for standard messages).
+- DMA support for all STM32 devices, except F2/F4/F7.
+- Better graphical display and color support.
+- New CMake build system for better IDE integration.
+- Top-level build scripts relicensed as BSD to allow easier adaptation.
+- LPUART driver for STM32.
+- DAC driver with DMA support for STM32.
+- Non-allocating util classes `modm::inplace_any` and `modm::inplace_function`.
+
+Integrated Projects:
+
+- LVGL added at v8.0.1.
+- Petit FatFs added at v0.03a.
+- FatFs upgraded to v0.14b.
+- TinyUSB upgraded to v0.10.1.
+- FreeRTOS upgraded to 202012 LTS.
+
+Fixes:
+
+- OpenOCD ITM configuration for logging.
+- Much more accurate nanosecond delay.
+- realloc with NULL pointer calls malloc when using TLSF allocator.
+
+New development boards:
+
+- NUCLEO-L031K6 as [`modm:board:nucleo-l031k6`][].
+- NUCLEO-F072RB as [`modm:board:nucleo-f072rb`][].
+- NUCLEO-L496ZG-P as [`modm:board:nucleo-l496zg-p`][].
+- NUCLEO-F091RC as [`modm:board:nucleo-f091rc`][].
+
+New device drivers:
+
+- SH1106 display as [`modm:driver:sh1106`][].
+- STTS22H thermometer as [`modm:driver:stts22h`][].
+
+Known bugs:
+
+- C++20 is not fully implemented by GCC10 yet, however modm does not use all
+  features yet anyways. See [#326][].
+- STM32F7: D-Cache not enabled by default. See [#485][].
+- `lbuild build` and `lbuild clean` do not remove all previously generated files
+  when the configuration changes. See [#285][].
+- Generating modm on Windows creates paths with `\` that are not compatible with
+  Unix. See [#310][].
+- `arm-none-eabi-gdb` TUI and GDBGUI interfaces are not supported on Windows.
+  See [#591][].
+
+Many thanks to all our contributors:

+- Christopher Durand ([@chris-durand][])
+- Jacob Schultz Andersen ([@jasa][])
+- Niklas Hauser ([@salkinium][])
+- Raphael Lehmann ([@rleh][])
