2022-07-01 Unreleased version
C++
* cpp_generated_lib_linked support is removed in protoc
* Reduced .pb.o object file size slightly by explicitly instantiating
InternalMetadata templates in the runtime.
* Add C++20 keywords guarded by PROTOBUF_FUTURE_CPP20_KEYWORDS
* Fixed crash in ThreadLocalStorage for pre-C++17 compilers on 32-bit ARM.
* Clarified that JSON API non-OK statuses are not a stable API.
* Added a default implementation of MessageDifferencer::Reporter methods.
* proto2::MapPair is now an alias to std::pair.
* Hide C++ RepeatedField::UnsafeArenaSwap
* Use table-driven parser for reflection based objects.
* Update Map's InternalSwap() to take a pointer to the other Map.
* Add ARM-optimized Varint decoding functions.
* Minor optimization for parsing groups
* Declare ReflectiveProtoHook class
* Reduce size of VarintParse code in protocol buffers, by calling the shared
routine after handling just one-byte varint encoding inline, rather than
handling one-byte and two-byte varints inline.
* Avoid inlining some large heavily duplicated routines in repeated_ptr_field.h
* Add ReflectiveProtoHook to Reflection.
* Turns on table-driven parser for reflection based objects.
* Save code space by avoiding inlining of large-in-aggregate code-space MessageLite::~MessageLite destructor.
* Undefine the macro `linux` when compiling protobuf
Kotlin
* Suppress deprecation warnings in Kotlin generated code.
* Kotlin generated code comments now use kdoc format instead of javadoc.
* Escape keywords in package names in proto generated code
* Add Kotlin enum int value getters and setters
Java
* Performance improvement for repeated use of FieldMaskUtil#merge by caching
constructed FieldMaskTrees.
* Optimized Java proto serialization gencode for protos having many extension ranges with few fields in between.
Python
* Changes ordering of printed fields in .pyi files from lexicographic to the same ordering found in the proto descriptor.
* Adds GeneratedCodeInfo annotations to python proto .pyi outputs as a base64 encoded docstring in the last line of the .pyi file for code analysis tools.
* Fix message factory's behavior in python cpp extension to return same message classes for same descriptor, even if the factories are different.
Compiler
* Print full path name of source .proto file on error
2022-08-09 version 21.5 (C++/Java/Python/PHP/Objective-C/C#/Ruby)

* 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

should not impact most users. For more information see:
