v0.6.5

v0.6.5 release

Please, read the getting started guide for flashing instructions.

Important note: this version uses a different partitioning layout for ESP32 Elixir images (and dedicated images) that have room for additional Elixir modules. Make sure to use updated tooling and offsets.

Known Issues

• i2c:write_bytes on ESP32 seems not working, use i2c:write_byte instead.

Added

• ESP32: add a new Elixir release "flavor" with a bigger boot.avm partition that has room for
  Elixir standard library modules
• ESP32: --boot option to mkimage.sh tool
• Add erlang:atom_to_binary/1 that is equivalent to erlang:atom_to_binary(Atom, utf8)
• Support for Elixir String.Chars protocol, now functions such as Enum.join are able to take
  also non string parameters (e.g. Enum.join([1, 2], ",")
• Support for Elixir Enum.at/3
• Add support for is_bitstring/1 construct which is used in Elixir protocols runtime.
• Add support to Elixir Enumerable protocol also for Enum.all?, Enum.any?, Enum.each,
  Enum.filter, Enum.flat_map, Enum.reject, Enum.chunk_by and Enum.chunk_while
• Support for maps:merge_with/3
• Support for lists:last/1 and lists:mapfoldl/3
• Add support to Elixir for Process.send/2 Process.send_after/3/4 and Process.cancel_timer/1
• Add support for handle_continue callback in gen_server
• Support for Elixir List.Chars protocol
• Support for gen_server:start_monitor/3,4
• Support for code:ensure_loaded/1
• Support for io_lib:latin1_char_list/1
• Add support to Elixir for Keyword.split/2
• Support for binary:split/3 and string:find/2,3
• Support for large tuples (more than 255 elements) in external terms.
• Support for io:put_chars/2
• Support for lists:nthtail/2
• Support for Elixir IO.chardata_to_string/1
• Support for Elixir List.duplicate/2
• Support for binary:copy/1,2
• Support for directory listing using POSIX APIs: (atomvm:posix_opendir/1,
  atomvm:posix_readdir/1, atomvm:posix_closedir/1).
• ESP32: add support for esp_adc ADC driver, with Erlang and Elixir examples
• Add handler for ESP32 network driver STA mode beacon_timeout (event: 21), see issue
  #1100
• Support for mounting/unmounting storage on ESP32 (such as SD or internal flash) using
  esp:mount/4 and esp:umount/1
• Support for binary_to_integer/2
• Support for binary:decode_hex/1 and binary:encode_hex/1,2
• Support for Elixir Base.decode16/2 and Base.encode16/2
• Make external term serialize functions available without using externalterm_to_binary so terms
  can be written directly to a buffer.
• Support for erlang:list_to_integer/2
• Add externalterm_to_term_copy that can be safely used from NIFs taking temporary buffers

Changed

• ESP32: Elixir library is not shipped anymore with esp32boot.avm. Use elixir_esp32boot.avm
  instead
• Enum.find_index and Enum.find_value support Enumerable and not just lists
• Install AtomVM libraries source code and binaries for better dialyzer integration
• Made the device_config properties list in spi:open/1 optional (defaults to []), so you can use the function with only a bus_config

Fixed

• ESP32: content of boot.avm partition is not truncated anymore
• ESP32: Fixed gpio:set_int to accept any pin, not only pin 2
• Fix memory corruption in unicode:characters_to_binary
• Fix handling of large literal indexes and large extended literal indexes
• unicode:characters_to_list: fixed bogus out_of_memory error on some platforms such as ESP32
• Fix crash in Elixir library when doing inspect(:atom)
• General inspect() compliance with Elixir behavior (but there are still some minor differences)
• Fix several uses of free on prevously released memory on ESP32, under certain error condition using
  network:start/1, that would lead to a hard crash of the VM.
• Fix a bug in ESP32 network driver where the low level driver was not being stopped and resoureces were not freed
  when network:stop/0 was used, see issue #643
• uart:open/1,2 now works with uppercase peripheral names
