CircuitPython 8.0.0

This is CircuitPython 8.0.0, the latest major revision of CircuitPython, and is a new stable release.

Note
Since 8.0.0-beta.6, the file for specifying startup values for WiFi, etc., is now called settings.toml instead of .env, and uses slightly different syntax. Use double quotes instead of single quotes. Further documentation is here.

Warning
The flash partitioning for 2MB and 4MB flash ESP32 and ESP32-C3 boards has changed since 8.0.0-beta.2.
When you load 8.0.0-beta.3 or later over beta.2 (or vice versa), on these boards, CIRCUITPY will be erased and reformatted.

Warning
The flash partitioning for the Raspberry Pi Pico W has changed since 8.0.0-beta.1.
When you load 8.0.0-beta.2 or later over beta.1 (or vice versa), on the Pico W, CIRCUITPY will be erased and reformatted.

Notable changes to 8.0.0 since 7.3.0

Functionality additions

• Add WiFi workflow with browser-based device discovery, filesystem browsing, upload, download, file editing, serial/REPL connection (available on Espressif and Pi Pico W).
• Add a one-line status bar, which displays connection status, last exception, and version on a terminal window title or on the top line of an attached display. Mu 1.2.0 and Thonny 4.0.x and later are able to suppress status bar information in the REPL output.
• A settings.toml file in CIRCUITPY provides environment variable values. Some value names are read by CircuitPython to specify WiFi connection parameters, BLE name, and other startup values. But you can also use settings.toml to specify your own parameters for your programs. Values from settings.toml can be retrieved using os.getenv(). More details here.
• WiFi functionality implemented on the Raspberry Pi Pico W.
• Revised Espressif camera support, now available on ESP32, ESP32-S2, and ESP32-S3.
• Bulk analog input: analogbufio (available only on RP2040 for now).
• Pin state can be preserved during deep sleep (available only on Espressif for now).
• Allow setting USB VID, PID, manufacturer, and product ids at runtime.
• Enable collections.deque on most builds.
• AnalogIn values are full range from 0 to 65535, instead of having zeros on low-order bits.
• In-place firmware update (dualbank) capability may be disabled at runtime in favor of a larger CIRCUITPY drive. This is the default.
• Add TileGrid.contains().
• Add os.utime().
• Add espulp module, for running programs on the ULP co-processor in Espressif chips.
• Add memorymap module for general though limited access to various memory regions.
• A serial "break" on the USB or UART REPL serial connection will cause a KeyboardInterrupt, like ctrl-C. The advantage over ctrl-C is that the break interrupts even if the input buffer is full.
• Add hidden property to vectorio shapes.
• Add native _pixelmap.PixelMap support, for speed.
• Chained exceptions are now implemented.
• Add VfsFat.readonly property.
• Add memorymap to allow access to raw memory locations (currently only on Espressif). #7359. Thanks @tannewt.

Compatibility changes

• PulseOut no longer accepts a PWMOut. Use a Pin instead.
• Auto-brightness support in displayio and framebufferio has been removed. It was never implemented completely.
• OneWire is only in onewireio, and is no longer in busio or bitbangio.
• gamepadshift has been removed: use keypad.ShiftRegisterKeys instead.
• MP3Decoder and WaveFile can now take a filename instead of an open file.
• Print out whole-number floats exactly and correctly.
• Restored rainbowio and onewireio to a number of boards. Some boards still have rainbowio turned off for space reasons.
• i2ctarget.I2CTarget is the new name for i2cperipheral.I2CPeripheral. Accept both for now. I2CPeripheral is deprecated and will be removed in 9.0.0.
• Allow display.root_group to be set, instead of using display.show(). display.show() is deprecated and will be removed in 9.0.0.
• The property supervisor.runtime.autoreload replaces supervisor.disable_autoreload() and supervisor.enable_autoreload().
• The property supervisor.runtime.ble_workflow replaces supervisor.disable_ble_workflow().
• The property supervisor.runtime.next_stack_limit replaces supervisor.set_next_stack_limit().
• The property supervisor.runtime.rgb_status_brightness replaces supervisor.set_rgb_status_brightness().

CircuitPython 8.0.0 Beta 5

This is CircuitPython 8.0.0-beta.5, a beta release for 8.0.0. It is relatively stable, but there will be further additions, fixes, and changes before final release.

WARNING: The flash partitioning for 2MB and 4MB flash ESP32 and ESP32-C3 boards has changed since 8.0.0-beta.2. When you load 8.0.0-beta.3 or later over beta.2 (or vice versa), on these boards, CIRCUITPY will be erased and reformatted.

WARNING: The flash partitioning for the Raspberry Pi Pico W has changed since 8.0.0-beta.1. When you load 8.0.0-beta.2 or later over beta.1 (or vice versa), on the Pico W, CIRCUITPY will be erased and reformatted.

Notable changes to 8.0.0 since 7.3.0

Functionality additions

• Added WiFi workflow with browser-based device discovery, filesystem browsing, upload, download, file editing, serial/REPL connection (available on Espressif and, as of 8.0.0-beta.5, Pi Pico W).
• Added a one-line status bar, which displays connection status, last exception, and version on a terminal window title or on the top line of an attached display. Mu 1.2.0 and Thonny 4.0.x and later are able to suppress status bar information in the REPL output.
• .env file in CIRCUITPY specifies WiFI connection parameters, BLE name, and other startup values.
• dotenv support: os.getenv() values are set by values in .env file. Values can be fetched from other dotenv-format files.
• WiFi functionality implemented on the Raspberry Pi Pico W.
• Revised Espressif camera support, now available on ESP32, ESP32-S2, and ESP32-S3.
• Bulk analog input: analogbufio (available only on RP2040 for now).
• Pin state can be preserved during deep sleep (available only on Espressif for now).
• Allow setting USB VID, PID, manufacturer, and product ids at runtime.
• Enabled collections.deque on most builds.
• MP3Decoder and WaveFile can now take a filename instead of an open file.
• AnalogIn values are full range from 0 to 65535, instead of having zeros on low-order bits.
• In-place firmware update (dualbank) capability may be disabled in favor of a larger CIRCUITPY drive.
• Added TileGrid.contains().
• Added os.utime().
• Added coproc module, for running programs on an on-chip co-processor. Currently available for the RISC-V core on the ESP32-S2 and ESP32-S3.
• A serial "break" on the USB or UART REPL serial connection will cause a KeyboardInterrupt, like ctrl-C. The advantage over ctrl-C is that the break interrupts even if the input buffer is full.
• Add hidden property to vectorio shapes.
• Add native _pixelmap.PixelMap support, for speed.
• Chained exceptions are now implemented.

Compatibility changes

• PulseOut no longer accepts a PWMOut. Use a Pin instead.
• Auto-brightness support in displayio and framebufferio has been removed. It was never implemented completely.
• OneWire is only in onewireio, and is no longer in busio or bitbangio.
• gamepadshift has been removed: use keypad.ShiftRegisterKeys instead.
• Print out whole-number floats exactly and correctly.
• Restored rainbowio and onewireio to a number of boards. Some boards still have rainbowio turned off for space reasons.
• i2ctarget.I2CTarget is the new name for i2cperipheral.I2CPeripheral. Accept both for now. I2CPeripheral is deprecated and will be removed in 9.0.0.
• Allow display.root_group to be set, instead of using display.show(). display.show() is deprecated and will be removed in 9.0.0.
• The property supervisor.runtime.ble_workflow replaces supervisor.disable_ble_workflow().
• The property supervisor.runtime.next_stack_limit replaces supervisor.set_next_stack_limit().
• The property supervisor.runtime.rgb_status_brightness replaces supervisor.set_rgb_status_brightness().

• Added a one-line status bar, which displays connection status, last exception, and version on a terminal window title or on the top line of an attached display. Support for status bar display is also being added to the Mu and Thonny editors.
• .env file in CIRCUITPY specifies WiFI connection parameters, BLE name, and other startup values.
• dotenv support: os.getenv() values are set by values in .env file. Values can be fetched from other dotenv-format files.
• WiFi functionality implemented on the Pi Pico W.
• Revised Espressif camera support, now available on ESP32, ESP32-S2, and ESP32-S3.
• Bulk analog input: analogbufio (available only on RP2040 for now).
• Pin state can be preserved during deep sleep (available only on Espressif for now).
• Allow setting USB VID, PID, manufacturer, and product ids at runtime.
• Enabled collections.deque on most builds.
• MP3Decoder and WaveFile can now take a filename instead of an open file.
• AnalogIn values are full range from 0 to 65535, instead of having zeros on low-order bits.
• In-place firmware update (dualbank) capability may be disabled in favor of a larger CIRCUITPY drive.
• Added TileGrid.contains().
• Added os.utime().

Compatibility changes

• PulseOut no longer accepts a PWMOut. Use a Pin instead.
• Auto-brightness support in displayio and framebufferio has been removed. It was never implemented completely.
• OneWire is only in onewireio, and is no longer in busio or bitbangio.
• gamepadshift has been removed: use keypad.ShiftRegisterKeys instead.
• Print out whole-number floats exactly and correctly.
• Restored rainbowio and onewireio to a number of boards. Some boards still have rainbowio turned
  off for space reasons.
• i2ctarget.I2CTarget is the new name for i2cperipheral.I2CPeripheral. Accept both for now. I2CPeripheral will be removed in 9.0.0.
• The property supervisor.runtime.ble_workflow replaces supervisor.disable_ble_workflow().
• The property supervisor.runtime.next_stack_limit replaces supervisor.set_next_stack_limit().
• The property supervisor.runtime.rgb_status_brightness replaces supervisor.set_rgb_status_brightness().
