Release 4.17.1

Version 4.17.1
2021-Apr-17

• Fix compilation with Elixir 1.12.0, by respecting the
  REBAR_BARE_COMPILER_OUTPUT_DIR env var during descriptor
  compilation. Thanks to Michael Davis. (#204, #205)

• On decoding, mask ints to 32 or 64 bits. (#206)

• Rename helpers/export-from-git to mk-versioned-archive
  and make it able to export also from a non-git dir,
  allowing the version to be set using options.
  Keep a symlink from the old name for backwards compatibility.

Release 4.17.0

Version 4.17.0
2021-Apr-11

• Save all options as well as custom options, and introduce
  versions 3 and 4 of the proto defs format. (#202)
  See the doc/dev-guide/proto-defs-versions.md for more info.

  The following definition elements were added and changed:

  • Enum values have changed from 2-tuples to 3-tuples:
    previously: {Symbol, Value}
    now: {Symbol, Value, EnumValueOptions}
  • Added: {{enum_options,EnumName}, [, ...]}
  • Added: {{service_options,ServiceName}, [, ...]}
  • Rpc (custom) option names now look like any other
    custom option names.
  • Option name elements can now contain tuples
    to indicate parenthesized path components, as indicated
    in the doc/dev-guide/proto-defs-versions.md.

  The above redesign also fixes a crash when there were
  enum option. (#203)

  The default version of the returned format and of the format
  in the generated introspection functions is still 1, for
  backwards compatibility. Use the {proto_defs_version,4} option
  in order to use the added definition elements.

• Add an option, introspect_get_proto_defs (-introspect-get_proto_defs)
  Normally a get_msg_defs/0 function is generated, but this
  has historically only contained message and enum elements.
  With the introspect_get_proto_defs option, a get_proto_defs/0
  is instead generated, containing the same definitions as returned
  when compiling with the to_proto_defs option.
  NB that the format version of the definitions for get_proto_defs/0,
  as well as those for get_msg_defs/0, is by default 1, but can
  be changed with the {proto_defs_version,N} option.

Release 4.16.2

Version 4.16.2
2021-Feb-27

• Rework the import handling to check full paths when checking
  if an proto to import has already been seen. #194
• In a verifier error, emit the faulty field as a string
  instead of as an atom to avoid hitting the system limit
  of 255 chars during the making of the error re ason. #195
• Fix spec for empty messages to work with dialyzer -Wunderspecs #196
  Also emit -dialyzer({no_underspecs, /}) on erl >= 24.
• Fix the Erlang type of string fields: change to unicode:chardata()
  from iodata() to allow for unicode code points >255. #200
  For clarity, the encoding always worked with such code points,
  it was just the field's type that was wrong.
• Fix help text when using protoc-erl.
• A few fixes for Erlang 24 (doc building and in an eunit test)
