+2018-06-01 version 3.6.0 (C++/Java/Python/PHP/Objective-C/C#/Ruby/JavaScript)
|
|
|
+
|
|
|
+ C++
|
|
|
+ * Starting from this release, we now require C++11. 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
