Advanced Installer

What's new in this version:

Announcements:
- Protobuf News may include additional announcements or pre-announcements for upcoming changes

Compiler:
- Drop support for Bazel 5
- Allow code generators to specify whether or not they support editions
- Release prototype of Protobuf Editions
- Compiler: Correct depfile generation when there are no outputs
- Add dllexport_decl for generated default instance
- In TSan mode, detect concurrent mutations of repeated/map fields
- Add a workaround for GCC constexpr bug
- Turn on the table-driven parser by default, as it is no longer experimental
- Shrink code size of generated protocol buffer code via a few
- Implement enforcement of target constraints
- Fix(libprotoc): export useful symbols from .so

C++:
- In OSS mode omit some extern template specializations. We have seen reports of compilers falling over due to the size of translation units.
- Automated rollback of
- Fix building shared libraries on MinGW-w64
- Enable TSan validation to detect when a mutable accessor of a message is called concurrently with another accessor on the same message, which is a data race.
- Release prototype of Protobuf Editions.
- Enable TSan validation to detect when a mutable accessor of a message is called concurrently with another accessor on the same message, which is a data race.
- Fix case of locality optimizer being wrong for split repeated fields and add a check that the optimized order has the same size as the unoptimized order.
- Enable TSan validation to detect when a mutable accessor of a message is called concurrently with another accessor on the same message, which is a data race.
- Mark single arg ctor explicit in DynamicMessageFactory.
- Enable TSan validation to detect when a mutable accessor of a message is called concurrently with another accessor on the same message, which is a data race.
- Let ParseRepeatedStringOnce call AllocateFromStringBlock()
- Check next tag in MpRepeatedMessage
- When parsing repeated primitives, append to a tmp array on stack
- Add dllexport_decl for generated default instance
- TextFormat::ParseFieldValueFromString now takes absl::string_view as input instead of const std::string &
- In TSan mode, detect concurrent mutations of repeated/map fields
- Use the same ABI for static and shared libraries on non-Windows platforms
- Replace ColdChunkSkipper with iterator-based approach
- Check invalid type_id after casting it to uint32_t.
- Strengthen assertions on reflection methods.
- Add assertions to reflection methods.
- Fail to parse message sets if type_id is zero.
- Enable the use of [SU]Int32Size and EnumSize templates for AArch64
- Add a workaround for GCC constexpr bug
- Add ABSL_ATTRIBUTE_LIFETIME_BOUND attribute on Map, RepeatedField and RepeatedPtrField
- Turn on the table-driven parser by default, as it is no longer experimental
- Fix: avoid warnings on MSVC
- Fix: avoid warnings on Windows
- Shrink code size of generated protocol buffer code via a few
- Fix(libprotoc): export useful symbols from .so
- Forbid embedded nulls in json_name
- Implement option retention for C#
- Implement enforcement of target constraints
- Make RepeatedField and RepeatedPtrField be destructor skippable for proto arenas.
- Update MessageDifferencer to conditionally force comparing additional fields while doing PARTIAL comparison
- CMake: Use the correct jsoncpp target name in static builds
- Fix: missing -DPROTOBUF_USE_DLLS in pkg-config
- Avoid using string(JOIN..., which requires cmake 3.12

Java:
- Put a 4k limit on preallocation to prevent OOM from malformed inputs
- Mark OneofDescriptor.isSynthetic() deprecated
- Use ProtobufArrayList for repeated bytes field. Presize primitive arrays for fixed-length primitives.
- Add protobuf-kotlin into protobuf-bom
- Handle clear for Java proto3 optionals
- Deps: Update Guava to 32.0.0
- Migrate repeated numeric fields to use bit field to track presence instead of using it to indicate the field mutability to potentially skip work on the field during build operations.
- Automated rollback of commit

Csharp:
- [C#] Replace regex that validates descriptor names
