v0.6.0-beta.1

v0.6.0-beta.1 release.

Please, read the getting started guide for flashing instructions.

CHANGELOG

Added

• Support for utf8 encoding to *_to_atom and atom_to_* functions
• binary_to_atom/1 and atom_to_binary/1 that default to utf8 (they were introduced with OTP23)
• Added Pico cmake option AVM_WAIT_BOOTSEL_ON_EXIT (default ON) to allow tools to use automated BOOTSEL mode after main application exits
• Use UTF-8 encoding for atoms when using erlang:term_to_binary/1, in conformance with OTP-26
• Pico: Wait for USB serial connection cmake configuration option AVM_USB_WAIT_SECONDS added with 20 second default.
• Support for code that makes use of more than 16 live registers, such as functions with > 16
  parameters and complex pattern matchings.

Fixed

• ESP32: fix i2c_driver_acquire and i2c_driver_release functions, that were working only once.
• Sending messages to registered processes using the ! operator now works.
• Fixed bug in OP_SEND that would accept sending a message to any integer or term without raising an error.
• binary_to_term checks atom encoding validity, and fix latin1 support (when non-ASCII chars are
  used)
• ESP32: fixed bug in gpio:set_pin_mode/2 and gpio:set_direction/3 that would accept any atom for the mode parameter without an error.
• ESP32: GPIO driver fix bug that would accept invalid pull direction, and silently set pull direction to floating without issuing an error.
• ESP32: fixed bug in gpio driver that would accept invalid pin numbers (either negative, or too large)
• RP2040: fixed bug in gpio:set_pin_pull/2 that would accept any parameter as a valid pull mode.
• Support to function with 10 or more parameters
• Very unlikely but possible corruption caused by generated code that uses 16 live registers

Changed

• binary_to_atom/2 validates utf8 strings
• *_to_atom and atom_to_* properly convert latin1 (not just ASCII) to utf8 and viceversa
• ESP32: use esp-idf v5.1.3 for building release binaries
