### Release Notes

<details>
<summary>protocolbuffers/protobuf</summary>

### [`v3.17.0`](https://togithub.com/protocolbuffers/protobuf/releases/v3.17.0)

[Compare Source](https://togithub.com/protocolbuffers/protobuf/compare/v3.16.0...v3.17.0)

### Protocol Compiler

-   Fix the generated source information for reserved values in Enums.

### C++

-   Fix -Wunused-parameter in map&lt;string, int> fields (fixes [#&#8203;8494](https://togithub.com/protocolbuffers/protobuf/issues/8494)) ([#&#8203;8500](https://togithub.com/protocolbuffers/protobuf/issues/8500))
-   Use byteswap.h when building against musl libc ([#&#8203;8503](https://togithub.com/protocolbuffers/protobuf/issues/8503))
-   Fix -Wundefined-inline error when using SharedCtor() or SharedDtor() ([#&#8203;8532](https://togithub.com/protocolbuffers/protobuf/issues/8532))
-   Fix bug where `Descriptor::DebugString()` printed proto3 synthetic oneofs.
-   Provide stable versions of `SortAndUnique()`.
-   Make sure to cache proto3 optional message fields when they are cleared.
-   Expose UnsafeArena methods to Reflection.
-   Use std::string::empty() rather than std::string::size() > 0.

### Kotlin

-   Restrict extension setter and getter operators to non-nullable T.

-   Reduce the time spent evaluating isExtensionNumber by storing the extension
    ranges in a TreeMap for faster queries. This is particularly relevant for
    protos which define a large number of extension ranges, for example when
    each tag is defined as an extension.
-   Fix java bytecode estimation logic for optional fields.
-   Optimize Descriptor.isExtensionNumber.

### Python

-   Add MethodDescriptor.CopyToProto() ([#&#8203;8327](https://togithub.com/protocolbuffers/protobuf/issues/8327))

-   Fix constness issue detected by MSVC standard conforming mode ([#&#8203;8568](https://togithub.com/protocolbuffers/protobuf/issues/8568))
-   Make JSON parsing match C++ and Java when multiple fields from the same
    oneof are present and all but one is null.

### Ruby

-   Add support for proto3 json_name in compiler and field definitions ([#&#8203;8356](https://togithub.com/protocolbuffers/protobuf/issues/8356))
-   Fixed memory leak of Ruby arena objects. ([#&#8203;8461](https://togithub.com/protocolbuffers/protobuf/issues/8461))

-   Fix various exceptions in Ruby on 64-bit Windows ([#&#8203;8563](https://togithub.com/protocolbuffers/protobuf/issues/8563))
