CHANGES

========

2013-02-27 version 2.5.0:

  General

  * New notion "import public" that allows a proto file to forward the content

    it imports to its importers. For example,

      // foo.proto

      import public "bar.proto";

      import "baz.proto";

      // qux.proto

      import "foo.proto";

      // Stuff defined in bar.proto may be used in this file, but stuff from

      // baz.proto may NOT be used without importing it explicitly.

    This is useful for moving proto files. To move a proto file, just leave

    a single "import public" in the old proto file.

  * New enum option "allow_alias" that specifies whether different symbols can

    be assigned the same numeric value. Default value is "true". Setting it to

    false causes the compiler to reject enum definitions where multiple symbols

    have the same numeric value.

  C++

  * New generated method set_allocated_foo(Type* foo) for message and string

    fields. This method allows you to set the field to a pre-allocated object

    and the containing message takes the ownership of that object.

  * Added SetAllocatedExtension() and ReleaseExtension() to extensions API.

  * Custom options are now formatted correctly when descriptors are printed in

    text format.

  * Various speed optimizations.

  Java

  * Comments in proto files are now collected and put into generated code as

    comments for corresponding classes and data members.

  * Added Parser to parse directly into messages without a Builder. For

    example,

      Foo foo = Foo.getParser().ParseFrom(input);

    Using Parser is ~25% faster than using Builder to parse messages.

  * Added getters/setters to access the underlying ByteString of a string field

    directly.

  * ByteString now supports more operations: substring(), prepend(), and

    append(). The implementation of ByteString uses a binary tree structure

    to support these operations efficiently.

  * New method findInitializationErrors() that lists all missing required

    fields.

  * Various code size and speed optimizations.

  Python

  * Added support for dynamic message creation. DescriptorDatabase,

    DescriptorPool, and MessageFactory work like their C++ couterparts to

    simplify Descriptor construction from *DescriptorProtos, and MessageFactory

    provides a message instance from a Descriptor.

  * Added pickle support for protobuf messages.

  * Unknown fields are now preserved after parsing.

  * Fixed bug where custom options were not correctly populated. Custom

    options can be accessed now.

  * Added EnumTypeWrapper that provides better accessibility to enum types.

  * Added ParseMessage(descriptor, bytes) to generate a new Message instance

    from a descriptor and a byte string.

The release looks really good. When can see the release on Maven Central?

A note on the "allow_alias" option: we plan to flip the default value to "false" in a future release. Projects using enum aliases should set this option to "true" in their proto files, otherwise they might be broken by future protobuf releases.

[Feng Xiao]

We are working on this. My estimation is that it should be available this or next week.

How soon, please? I am happy for new version but I miss reading of how to make use of it.

It has already been updated: https://developers.google.com/protocol-buffers/docs/overview
