Release 4.21.1

Version 4.21.1
2024-Feb-19

• Update to support Erlang 27
• Bugfix edoc for {json_format, maps}

Release 4.21.0

Version 4.21.0
2024-Jan-07

• Update the set of Google well-known protos by
  importing from protobuf 4.25.1. Thanks to Gilbert. (#231)
• Add the possibility to parse a descriptor back to
  gpb-internal definitions.
• Fix several minor bugs in the generation of descriptors.
• Set a minimum heap size to benchmarks to avoid excessive gc.

Release 4.20.0

Version 4.20.0
2023-Oct-01

• Add an option enum_macros (-gen-enum-macros) to generate macros for
  enum values, with the intention to make it possible to catch
  enumerator symbol changes already in compile-time (#229)
  Add sub-options {rename,{What,uppercase}}
  and {rename,{enum_macros,How}} (corresponding to
  -rename What:uppercase and -rename enum_macro:How)
• Add an option allow_preencoded_submsgs to specify a binary
  for a sub-message. The intention is to make it encoding faster
  if sub-messages are already known or occur several times. (#220)
• Add options {gen_encoders,bool()} and {gen_decoders,bool()}
  to make it possible to omit encoders or decoders. The intention is
  is to make it possible to shrink the footprint when not only
  encoding or decoding is needed.
• Bugfix the cmd line option -rename What:lowercase.
• Support Erlang 26.1 and later. In Erlang 26.1 and later, exact
  comparison with zero must now be written as +0.0 or -0.0, as a
  preparation for Erlang 27. This is for both generated code
  and in gpb eunit tests. (#230)

Release 4.19.9

Version 4.19.9
2023-Aug-06

• Fix verifiers to catch floats for int fields. (#228)

• Fix code generation for options mapfields_as_maps and json (#227)
• Support Google protobuf 22.0 and later with NIFs and JSON.

  dialyzer issues with Erlang 26.
• Don't generate gpb_version.hrl unnecessarily.

Release 4.19.7

Version 4.19.7
2023-Feb-04

• Support Google protobuf 3.16 and later with nifs.
• Add an option {gen_verifiers, false} (no-gen-verifiers).
  This implies {verify, never} (-v never)
• Don't emit -include("gpb.hrl") when not generating introspection
  functions. It is not needed.

Release 4.19.6

Version 4.19.6
2022-Sep-24

• Bugfix spec order for msg_name_to_fqbin and fqbin_to_msg_name
  when there are no messages. (#221)

  performance. Thanks to Saša Jurić. (#218)

Release 4.19.5

Version 4.19.5
2022-Mar-17
