- Support bus events disconnection/suspend/resume/wakeup
- Improve transfer performance with optimizing xfer and fifo size
- Support Highspeed port (OTG_HS) with both internal and external PHY
- Support multiple usb ports with rhport=1 is highspeed on selected MCUs e.g H743, F23. It is possible to have OTG_HS to run on Fullspeed PHY (e.g lacking external PHY)
- Add ISO transfer, fix odd/even frame
- Fix FIFO flush during stall
- Implement dcd_edpt_close() API
- Support F105, F107
- Enhance STM32 fsdev
- Improve dcd fifo allocation
- Fix ISTR race condition
- Support remap USB IRQ on supported MCUs
- Implement dcd_edpt_close() API
- Enhance NUC 505: enhance set configure behavior
- Enhance SAMD
- Fix race condition with setup packet
- Add SAMD11 option `OPT_MCU_SAMD11`
- Add SAME5x option `OPT_MCU_SAME5X`
- Fix SAMG control data toggle and stall race condition
- Enhance nRF
- Fix hanged when tud_task() is called within critical section (disabled interrupt)
- Add new class driver for **Bluetooth HCI** class driver with example can be found in [mynewt-tinyusb-example](https://github.com/hathach/mynewt-tinyusb-example) since it needs mynewt OS to run with.
- Fix USBD endpoint usage racing condition with `usbd_edpt_claim()/usbd_edpt_release()`
- Added `tud_task_event_ready()` and `osal_queue_empty()`. This API is needed to check before enter low power mode with WFI/WFE
- Rename USB IRQ Handler to `dcd_int_handler()`. Application must define IRQ handler in which it calls this API.
- Add `dcd_connect()` and `dcd_disconnect()` to enable/disable internal pullup on D+/D- on supported MCUs.
- Add `usbd_edpt_open()`
- Remove `dcd_set_config()`
- Add *OPT_OS_CUMSTOM* as hook for application to overwrite and/or add their own OS implementation
- Support SET_INTERFACE, GET_INTERFACE request
- Add Logging for debug with optional uart/rtt/swo printf retarget or `CFG_TUSB_DEBUG_PRINTF` hook
- Improve USB Highspeed support with actual link speed detection with `dcd_event_bus_reset()`
- Enhance class driver management
-`usbd_driver_open()` add max length argument, and return length of interface (0 for not supported). Return value is used for finding appropriate driver
- Add application implemented class driver via `usbd_app_driver_get_cb()`
Added **CONTRIBUTORS.md** to give proper credit for contributors to the stack. Special thanks to [Nathan Conrad](https://github.com/pigrew), [Peter Lawrence](https://github.com/majbthrd) and [William D. Jones](https://github.com/cr1901) and others for spending their precious time to add lots of features and ports for this release.
First release, device stack works great, host stack works but still need improvement.
- Special thanks to @adafruit team, especially @tannewt to help out immensely to rework device stack: simplify osal & control transfer, adding SAMD21/SAMD51 ports, writing porting docs, adding MIDI class support etc...
