Double precision math library and support on pyboard, and improved ussl
This release brings general improvements and bug fixes to the core and
various ports, as well as documentation additions, clean-ups and better
consistency. And effort has been made to clean up the source code to
make it more consistent across the core and all ports.
There is a new tool "mpy_bin2res.py" to convert arbitrary (binary) files
to Python resources for inclusion in source code (frozen or otherwise).
The ussl module has seen improvements, including implementation of
server_hostname (for axtls) and server_side mode (for mbedtls).
There is now a double-precision float math library and stmhal has support
to build firmware with software or hardware double-precision.

docs/library/ubinascii: Update base64 docs.
This clarifies return values and the handling of invalid (e.g. newline) characters. Encoding conforms to RFC 3548, but decoding does not, as it ignores invalid characters in base64 input. Instead, it conforms to MIME handling of base64 (RFC 2045). Note that CPython doesn't document handling of invalid characters in a2b_base64() docs: https://docs.python.org/3/library/binascii.html#binascii.a2b_base64 , so we specify it more explicitly than it, based on CPython's actual behavior (with which MicroPython now compliant). |

extmod/modubinascii: Rewrite mod_binascii_a2b_base64.
This implementation ignores invalid characters in the input. This allows it to decode the output of b2a_base64, and also mimics the behavior of CPython. |

py/binary: Change internal bytearray typecode from 0 to 1.
The value of 0 can't be used because otherwise mp_binary_get_size will let a null byte through as the type code (intepreted as byterray). This can lead to invalid type-specifier strings being let through without an error in the struct module, and even buffer overruns. |

New VFS subsystem and scheduling framework, and less need for the heap
This release adds some fundamental new components, allows for more Python
operations without using the heap and has reduced code size and stack
usage.
Changes in the way iterators are handled allows to iterate without
allocating on the heap for the types: tuple, list, str, bytes, bytearray,
array, dict, set, frozenset. It also allows to call the builtins all, any,
min max and sum without allocating heap memory for the iterator argument.
And improvements to the handling of super() means that super().foo() method
calls are now heap-less.
A new generic VFS subsystem has been added which allows to mount arbitrary
filesystems (even written in Python) at the root or at a mount-point within
the root. The FatFS driver has been replaced with an object-oriented
version (oofatfs) which allows a fully customisable filesystem layout.
A scheduling framework has been implemented in the core which gives the
ability to schedule callbacks to be called "as soon as possible". This
allows ports to implement "soft IRQs" which allow the programmer to
allocate memory during an interrupt handler, at the cost of some
performance related to response time of the handler. The new
micropython.schedule() function gives access to the scheduler.
Other improvements to the core include: consts can now be big-nums, for
example "X = const(1 << 100)"; addition of "help('modules')" to list
available modules; stack usage reduced for a Python call by 8 bytes on ARM
Cortex-M architectures; micropython.kbd_intr() function added to disable
Ctrl-C capture; addition of uio.resource_stream(); mpy-cross is built
automatically if needed; a helper tool mpy_cross_all.py is added to run
mpy-cross on an entire project.
The bytecode has changed in this version so existing .mpy files will need
recompiling. There have also been some changes to the C API, most notably
with mp_uint_t changed to size_t in many places.
In the extended modules the following main changes have been made: addition
of machine.Signal class to allow inversion on a Pin; framebuf has new
formats of the form MONO_xxx; addition of uselect.ipoll() for allocation-
free polling; addition of uos.ilistdir() for efficient iteration of a
directory listing; machine.Pin high/low methods are renamed to on/off in
esp8266 and zephyr (this is a backwards-incompatible change);
machine.time_pulse_us() function no longer throws exceptions, but returns
negative values instead.
For stmhal the pyb.fault_debug() function is added, and default behaviour
for a hard-fault is now an immediate reset. There is better support for F7
MCUs, in particular DMA and SD card support. A bug has been fixed with the
USB VCP (USB serial) where it would in rare cases (usually when the host PC
was under load) would lose characters. Pyboard now automatically mounts
all available partitions on the SD card. Multithreading has been
implemented and is available via the _thread module, but this feature is
disabled by default and must be enabled at compile time using the
MICROPY_THREAD and MICROPY_THREAD_GIL options. The ability to skip booting
from SD card is now available by creating an empty file on the flash called
"SKIPSD".
The cc3200 port has had some backwards incompatible changes, in particular
with I2C, Pin, UART and uos. Please see the documentation for the new
behaviour.
The esp8266 port has had a change in the size of the firmware in order to
accommodate additional features. As such the filesystem for this version
is incompatible with v1.8.7 and a device requires backup and erasure before
flashing this version. Soft IRQs are now implemented for Pin and Timer
callbacks, along with the general improvements described above.
In the documentation there is now a section describing the differences
between MicroPython and CPython. And code coverage is up to 98% across py/
and extmod/.
Changes in code size (in bytes) between v1.8.7 and this version are:
bare-arm: -1104
minimal: -1324
unix x64: -1115
unix nanbox: -11106
stmhal: +18116
cc3200: +1032
esp8266: +3060
Note that stmhal has increased significantly due to the addition of frozen
bytecode and the LCD160CR driver.

Merge tag 'v1.8.7' into parse-bytecode
Support for Xtensa emitter and assembler, and upgraded F4 and F7 STM HAL This release adds support for the Xtensa architecture as a target for the native emitter, as well as Xtensa inline assembler. The int.from_bytes and int.to_bytes methods now require a second argument (the byte order) per CPython (only "little" is supported at this time). The "readall" method has been removed from all stream classes that used it; "read" with no arguments should be used instead. There is now support for importing packages from compiled .mpy files. Test coverage is increased to 96%. The generic I2C driver has improvements: configurable clock stretching timeout, "stop" argument added to readfrom/writeto methods, "nack" argument added to readinto, and write[to] now returns num of ACKs received. The framebuf module now handles 16-bit depth (generic colour format) and has hline, vline, rect, line methods. A new utimeq module is added for efficient queue ordering defined by modulo time (to be compatible with time.ticks_xxx functions). The pyboard.py script has been modified so that the target board is not reset between scripts or commands that are given on a single command line. For the stmhal port the STM Cube HAL has been upgraded: Cube F4 HAL to v1.13.1 (CMSIS 2.5.1, HAL v1.5.2) and Cube F7 HAL to v1.1.2. There is a more robust pyb.I2C implementation (DMA is now disabled by default, can be enabled via an option), and there is an implementation of machine.I2C with robust error handling and hardware acceleration on F4 MCUs. It is now recommended to use machine.I2C instead of pyb.I2C. The UART class is now more robust with better handling of errors/timeouts. There is also more accurate VBAT and VREFINT measurements for the ADC. New boards that are supported include: NUCLEO_F767ZI, STM32F769DISC and NUCLEO_L476RG. For the esp8266 port select/poll is now supported for sockets using the uselect module. There is support for native and viper emitters, as well as an inline assembler (with limited iRAM for storage of native functions, or the option to store code to flash). There is improved software I2C with a slight API change: scl/sda pins can be specified as positional only when "-1" is passed as the first argument to indicate the use of software I2C. It is recommended to use keyword arguments for scl/sda. There is very early support for over-the-air (OTA) updates using the yaota8266 project. A detailed list of changes follows. py core: - emitnative: fix native import emitter when in viper mode - remove readall() method, which is equivalent to read() w/o args - objexcept: allow clearing traceback with 'exc.__traceback__ = None' -

Merge tag 'v1.8.6' into parse-bytecode
ESP8266 port uses SDK 2.0, has more heap, has support for 512k devices
This release brings some code size reductions to the core as well as
more tests and improved coverage which is now at 94.3%.
The time.ticks_diff(a, b) function has changed: the order of the arguments
has been swapped so that it behaves like "a - b", and it can now return a
negative number if "a" came before "b" (modulo the period of the ticks
functions).
For the ESP8266 port the Espressif SDK has been updated to 2.0.0, the
heap has been increased from 28k to 36k, and there is support for 512k
devices via "make 512k". upip is included by default as frozen bytecode.
The network module now allows access-point reconnection without WiFi
credentials, and exposes configuration for the station DHCP hostname. The
DS18B20 driver now handles negative temperatures, and NeoPixel and APA102
drivers handle 4 bytes-per-pixel LEDs.
For the CC3200 port there is now support for loading of precompiled .mpy
files and threading now works properly with interrupts.

Merge tag 'v1.8.5' into parse-bytecode
New port to Zephyr, upip runs on baremetal, and reduction in code size
This release adds a new port of MicroPython to run on top of the Zephyr
real-time operating system. As part of this there is now basic support for
using mbedTLS as the ussl module. The release also brings initial support
for running the package manager upip on baremetal systems with low heap
memory (such as esp8266), through a Python module interface.
Work has been done in this release to clean up the core, removing redundant
and/or unreachable code, and factoring existing duplicated code patterns.
This brings a reduction of 828 bytes in code size to the bare-arm port, and
1368 bytes to the minimal port. There is also improved coverage through
the addition of new tests for corner cases.
The "micropython" module sees the addition of the "const" identity function
which should be used as "from micropython import const" in scripts that
want to use the MicroPython constant optimisations in the compile stage.
There is also the addition of the "opt_level" function to change the
parser/compiler optimisation level at runtime.
The behaviour of "sys.exit" (and "raise SystemExit") on baremetal is now
changed: this function no longer does a soft-reset of the board, rather it
just stops the running script and drops to the REPL. In order to do an
actual soft reset the "machine.soft_reset" function has been added (to the
stmhal port only, for the time being).
Following CPython, KeyError exceptions for dictionary lookups now have the
failed key stored as the argument of the exception instance, accessible as
exc.args[0]. The "ujson.load" function has also been added, to load JSON
data from an arbitrary stream.
The I2C support in the machine module now has clock stretching, the
addition of the "addrsize" parameter in memory transfer methods, and I2C
scanning now uses dummy writes instead of dummy reads to make the scanning
more reliable.
The CMSIS library has been upgrade to v4.30, and the boards section of
the stmhal port has been refactored to use a common.ld script. The stmhal
port now has a full implementation of the machine.SPI class, with support
for both hardware SPI peripherals and fast software SPI. The USB HID
driver in stmhal has added support to receive USB HID messages from the
host.

Support for stream decompression in uzlib, and more ESP8266 features
This release includes some bug fixes, code clean-up, updates to the docs,
more tests, and various feature additions. The uzlib module now supports
efficient stream decompression in the form of the uzlib.DecompIO class.
Freezing of bytecode now supports floats for the ESP8266 port, as well as
complex numbers for all ports. The stmhal port has ADC working on L4
microcontrollers, fixed initialisation for DAC, and addition of the
machine.WDT class and machine.reset_cause function.
For the ESP8266 port Pin(16) now works as an input pin and the hardware
SPI peripheral is exposed as machine.SPI(1). The os.umount function is
implemented and the port supports mounting of externally connected SD
cards. The machine.WDT class is added, wlan.scan() is fixed to return all
access points, and there is support for DS18S20 devices.
