Release 4.21.7

Version 4.21.7
2025-Feb-06

• Adapt for Erlang 29 (based on current OTP master, thus a
  current guesstimate of needed changes)
  The generated code already worked with Erlang 29, but gpb
  itself needed some fixes to compile cleanly.

Release 4.21.6

Version 4.21.6
2025-Dec-18

• Bugfix unnecessary funtions with map type fields and
  options {gen_decoders,false} or {gen_encoders,false} (Options
  -no_gen_decoders or -no_gen_encoders) resulting in
  compilation warnings. (#242)

Release 4.21.5

Version 4.21.5
2025-Sep-14

• Bugfix verification and decoding for flat oneof with
  maps with binary keys. Thanks to Thales Macedo Garitezi. (#239)

Release 4.21.4

Version 4.21.4
2025-Aug-13

• Support Google protobuf 30.0 and later with NIFs.

Release 4.21.3

Version 4.21.3
2025-Jan-13

• Add priv/proto3/google/protobuf/LICENSE covering
  the .proto files in that directory. Thanks to Peter Lemenkov.

Release 4.21.2

Version 4.21.2
2024-Dec-28

• Add a missing option to the gpb_defs:def() type. Thanks to
  Paulo F. Oliveira. (#236)
• Support Google protobuf 26.0 and later with NIGs and JSON.
  This version of Google protobuf deprecates the JSON option
  always_print_primitive_fields and adds another option, the
  always_print_fields_with_no_presence. Gpb now supports both
  options. In gpb they both have the same behaviour as the
  always_print_fields_with_no_presence option. For proto3
  optional fields with omitted values, this brings a change,
  in that the such fields are now printed for JSON.

Release 4.21.1

Version 4.21.1
2024-Feb-19

• Emit @generated to mitigate a performance issue with ELP (#233)
• 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)
