For those we cannot yet + upgrade to C++11, we will try to keep the 3.5.x branch updated with + critical bug fixes only. If you have any concerns about this, please + comment on issue #2780. + * Moved to C++11 types like std::atomic and std::unique_ptr and away from our + old custom-built equivalents. + * Added support for repeated message fields in lite protos using implicit + weak fields. This is an experimental feature that allows the linker to + strip out more unused messages than previously was possible. + * Fixed SourceCodeInfo for interpreted options and extension range options. + * Fixed always_print_enums_as_ints option for JSON serialization. + * Added support for ignoring unknown enum values when parsing JSON. + * Create std::string in Arena memory. + * Fixed ValidateDateTime to correctly check the day. + * Fixed bug in ZeroCopyStreamByteSink. + * Various other cleanups and fixes. + + Java + * Dropped support for Java 6. + * Added a UTF-8 decoder that uses Unsafe to directly decode a byte buffer. + * Added deprecation annotations to generated code for deprecated oneof + fields. + * Fixed map field serialization in DynamicMessage. + * Cleanup and documentation for Java Lite runtime. + * Various other fixes and cleanups + * Fixed unboxed arraylists to handle an edge case + * Improved performance for copying between unboxed arraylists + * Fixed lite protobuf to avoid Java compiler warnings + * Improved test coverage for lite runtime + * Performance improvements for lite runtime + + Python + * Fixed bytes/string map key incompatibility between C++ and pure-Python + implementations (issue #4029) + * Added __init__.py files to compiler and util subpackages + * Use /MT for all Windows versions + * Fixed an issue affecting the Python-C++ implementation when used with + Cython (issue #2896) + * Various text format fixes + * Various fixes to resolve behavior differences between the pure-Python and + Python-C++ implementations + + PHP + * Added php_metadata_namespace to control the file path of generated metadata + file. + * Changed generated classes of nested message/enum. E.g., Foo.Bar, which + previously generates Foo_Bar, now generates Foo/Bar + * Added array constructor. When creating a message, users can pass a php + array whose content is field name to value pairs into constructor. The + created message will be initialized according to the array. Note that + message field should use a message value instead of a sub-array. + * Various bug fixes. + + Objective-C + * We removed some helper class methods from GPBDictionary to shrink the size + of the library, the functionary is still there, but you may need to do some + specific +alloc / -init… methods instead. + * Minor improvements in the performance of object field getters/setters by + avoiding some memory management overhead. + * Fix a memory leak during the raising of some errors. + * Make header importing completely order independent. + * Small code improvements for things the undefined behaviors compiler option + was flagging. + + Ruby + * Added ruby_package file option to control the module of generated class. + * Various bug fixes. + + Javascript + * Allow setting string to int64 field. + + Csharp + * Unknown fields are now parsed and then sent back on the wire. They can be + discarded at parse time via a CodedInputStream option. + * Movement towards working with .NET 3.5 and Unity + * Expression trees are no longer used + * AOT generics issues in Unity/il2cpp have a workaround (see this commit for + details) + * Floating point values are now compared bitwise (affects NaN value + comparisons) + * The default size limit when parsing is now 2GB rather than 64MB + * MessageParser now supports parsing from a slice of a byte array + * JSON list parsing now accepts null values where the underlying proto + representation does + +2017-12-20 version 3.5.1 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript) + Planned Future Changes + * Make C++ implementation C++11 only: we plan to require C++11 to build + protobuf code starting from 3.6.0 release.

If you’d like + to drop unknown fields, please use the DiscardUnknownFieldsParser API.
