# 0.7.0
*November 7, 2020*
## Device Controller Driver
- Added new support for Espressif ESP32-S2
- Added new support for Dialog DA1469x
- Enhance STM32 Synopsys
- 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`
### SAMG
- Fix SAMG control data toggle and stall race condition
### Enhance nRF
- Fix hanged when `tud_task()` is called within critical section (disabled interrupt)
- Fix disconnect bus event not submitted
- Implement ISO transfer and `dcd_edpt_close()`
## USB Device
### USBD
- 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
- Add IAR compiler support
- Support multiple configuration descriptors. `TUD_CONFIG_DESCRIPTOR()` template has extra config_num as 1st argument
- 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()`
- IAD is handled to assign driver id
- Added `tud_descriptor_device_qualifier_cb()` callback
- Optimize `tu_fifo` bulk write/read transfer
- Forward non-std control request to class driver
- Let application handle Microsoft OS 1.0 Descriptors (the 0xEE index string)
- Fix OSAL FreeRTOS yield from ISR
- Rename some configure macro to make it clear that those are used directly for endpoint transfer
- `CFG_TUD_HID_BUFSIZE` to `CFG_TUD_HID_EP_BUFSIZE`
- `CFG_TUD_CDC_EPSIZE` to `CFG_TUD_CDC_EP_BUFSIZE`
- `CFG_TUD_MSC_BUFSIZE` to `CFG_TUD_MSC_EP_BUFSIZE`
- `CFG_TUD_MIDI_EPSIZE` to `CFG_TUD_MIDI_EP_BUFSIZE`
### USBNET
- Remove ACM-EEM due to lack of support from host
### USBTMC
- Fix descriptors when INT EP is disabled
### CDC
- Send zero length packet for end of data when needed
- Add `tud_cdc_tx_complete_cb()` callback
- Change `tud_cdc_n_write_flush()` return number of bytes forced to transfer, and flush when writing enough data to fifo
### MIDI
- Add packet interface
- Add multiple jack descriptors
- Fix MIDI driver for sysex
### DFU Runtime
- fix response to SET_INTERFACE and DFU_GETSTATUS request
### HID
- Fix gamepad template descriptor
- Add multiple HID interface API
- Add extra comma to HID_REPORT_ID
## USB Host
- Rework USB host stack (still work in progress)
- Fix compile error with pipehandle
- Rework usbh control and enumeration as non-blocking
- Improve Hub, MSC, HID host driver
## Examples
- Add new `hid_composite_freertos`
- Add new `dynamic_configuration` to demonstrate how to switch configuration descriptors
- Add new `hid_multiple_interface`
- Enhance `net_lwip_webserver` example
- Add multiple configuration: RNDIS for Windows, CDC-ECM for macOS (Linux will work with both)
- Update lwip to STABLE-2_1_2_RELEASE for `net_lwip_webserver`
- Added new Audio example: `audio_test` `uac2_headsest`
## New Boards
- Espressif ESP32-S2: saola_1, kaluga_1
- STM32: F746 Nucleo, H743 Eval, H743 Nucleo, F723 discovery, stlink v3 mini, STM32L4r5 Nucleo
- Dialog DA1469x dk pro and dk usb
- Microchip: Great Scoot Gadgets' LUNA, samd11_xplained, D5035-01, atsamd21 xplained pro
- nRF: ItsyBitsy nRF52840
