2022-08-09 version 21.5 (C++/Java/Python/PHP/Objective-C/C#/Ruby) PHP * Added getContainingOneof and getRealContainingOneof to descriptor. * fix PHP readonly legacy files for nested messages Python * Fixed comparison of maps in Python. 2022-07-25 version 21.4 (C++/Java/Python/PHP/Objective-C/C#/Ruby) C++ * Reduce the required alignment of ArenaString from 8 to 4 (#10298) 2022-07-19 version 21.3 (C++/Java/Python/PHP/Objective-C/C#/Ruby) C++ * Add header search paths to Protobuf-C++.podspec (#10024) * Fixed Visual Studio constinit errors (#10232) * Fix #9947: make the ABI compatible between debug and non-debug builds (#10271) UPB * Allow empty package names (fixes behavior regression in 4.21.0) * Fix a SEGV bug when comparing a non-materialized sub-message (#10208) * Fix several bugs in descriptor mapping containers (eg. descriptor.services_by_name) * for x in mapping now yields keys rather than values, to match Python conventions and the behavior of the old library. * Lookup operations now correctly reject unhashable types as map keys. * We implement repr() to use the same format as dict. * Fix maps to use the ScalarMapContainer class when appropriate * Fix bug when parsing an unknown value in a proto2 enum extension (protocolbuffers/upb#717) PHP * Add "readonly" as a keyword for PHP and add previous classnames to descriptor pool (#10041) Python * Make //:protobuf_python and //:well_known_types_py_pb2 public (#10118) Bazel * Add back a filegroup for :well_known_protos (#10061) 2022-06-27 version 21.2 (C++/Java/Python/PHP/Objective-C/C#/Ruby) C++ * ArenaString improvements (fix alignment issue) PHP * API changes for OneOf (#10102) 2022-05-27 version 21.1 (C++/Java/Python/PHP/Objective-C/C#/Ruby) C++ * cmake: Revert "Fix cmake install targets (#9822)" (#10060) * Remove Abseil dependency from CMake build (#10056) Python * Update python wheel metadata with more information incl. required python version (#10058) * Fix segmentation fault when instantiating field via repeated field assignment (#10066) 2022-05-25 version 21.0 (C++/Java/Python/PHP/Objective-C/C#/Ruby) C++ * cmake: Call get_filename_component() with DIRECTORY mode instead of PATH mode (#9614) * Escape GetObject macro inside protoc-generated code (#9739) * Update CMake configuration to add a dependency on Abseil (#9793) * Fix cmake install targets (#9822) * Use __constinit only in GCC 12.2 and up (#9936) Java * Update protobuf_version.bzl to separate protoc and per-language java … (#9900) Python * Increment python major version to 4 in version.json for python upb (#9926) * The C extension module for Python has been rewritten to use the upb library. This is expected to deliver significant performance benefits, especially when parsing large payloads. There are some minor breaking changes, but these should not impact most users.
