+## 2023-07-01: 2023q2 release
+
+This release covers everything from 2023-04-05 and has been tested with avr-gcc
+v12.2.0 from Upstream and arm-none-eabi-gcc v12.2.1 from xpack.
+
+Breaking changes:
+
+- GCC12 requirement for C++23.
+- `-fsingle-precision-constant` default compile flag has been removed.
+- Removed deprecated `Timer::setPeriod(uint32_t)` in favor of`std::chrono` units.
+
+Features:
+
+- SAMx7x DAC, ADC, DMA, and CAN drivers.
+- Enabled C++23 and C23.
+- STM32 IWDG driver.
+- Fibers are now backward compatible with protothreads and resumable functions.
+- Support for STM32G0B/C devices with shared interrupts.
+
+Integrated Projects:
+
+- LVGL upgraded to v8.3.7.
+- Pico-SDK upgraded to v1.5.1.
+- STM32F1 headers upgraded to v4.3.4.
+- STM32F2 headers upgraded to v2.2.6.
+- STM32L1 headers upgraded to v2.3.3.
+- CMSIS-DSP upgraded to v1.14.4.
+- SAMx7x upgraded to v3.0.
+- TinyUSB upgraded to v0.15.0.
+
+Fixes:
+
+- Moving average type selection.
+- SysTick clock access from both cores on RP2040.
+- FDCAN driver on STM32 tx message queue.
+- STM32 I2C NACK flag is acknowledged for instances >1.
+- Fix arithmetic overflow in `Timer::setPeriod` on STM32.
+- Validate calculated CRC on MS5611 driver.
+
+New development boards:
+
+- Adafruit Feather-M4 as [`modm:feather-m4`][].
+
+New device drivers:
+
+- MAX31865 temperature sensor as [`modm:driver:max31865`][].
+- Internal cycle counter as [`modm:driver:cycle_counter`][].
+- MCP3008 ADC driver as [`modm:driver:mcp3008`][].
+
+Known bugs:
+
+- 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.
+A special shoutout to first timers 🎉:
+
+- Christopher Durand ([@chris-durand][])
+- Daniel Waldhäusl 🎉
+- Henrik Hose ([@hshose][])
+- Niklas Hauser ([@salkinium][])
+- Raphael Lehmann ([@rleh][])

+Known bugs:
+
+- 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.
