• Clarify order of returned list for descriptor objects in as.list documentation.

• Correct the definition of as.list for EnumDescriptors to return a proper list instead of a named vector.

• Update the default print methods to use cat() with fill=TRUE instead of show() to eliminate the confusing [1] since the classes in RProtoBuf are not vectorized.

• Add support for serializing function, language, and environment objects by falling back to R's native serialization with serialize_pb and unserialize_pb to make it easy to serialize into a Protocol Buffer all of the more than 100 datasets which come with R.

• Use normalizePath instead of creating a temporary file with file.create when getting absolute path names.

• Add unit tests for all of the above.

Changes in RProtoBuf version 0.4.1 (2014-03-25)

• Changes to support CRAN builds for MS Windows.

• Added functions serialize_pb, unserialize_pb, and can_serialize_pb plus documentation from Jeroen Ooms RProtoBufUtils package.

• New dir inst/python with some Python examples.

• Added Jeroen Ooms as author.

• Vignettes have been converted to the R 3.0.0 or later use of external vignette builders, no longer need a Makefile

• Added missing methods to dollar completion list for Message, Descriptor, EnumValueDescriptor, and FileDescriptor classes.

• Add missing export for .DollarNames EnumValueDescriptor to allow completion on that class.

• Add more than 15 additional pages to the main Intro vignette documenting better all of the S4 classes implemented by RProtoBuf, updating the type mapping tables to take into account 64-bit support, and documenting advanced features such as Extensions.

• Added better error checking in EnumDescriptors to catch the case when wrong types are provided.

• Updated the FileDescriptor name() method to accept a boolean for full paths just like the generic name() method.

• Correct a bug that incorrectly dispatched as.character() when as.list() was called on Descriptor objects.

• Update FileDescriptor $ dispatch to work properly for the names of fields defined in the FileDescriptor, instead of just returning NULL even for types returned by $ completion.

• Added a reservation for extension fields in the example tutorial.Person schema.

• Support setting int32 fields with character representations and raise an R-level stop() error if the provided string can not be parsed as a 32-bit integer, rather than crashing the R instance.

• Update the project TODO file.

• Add better documentation and tests for all of the above.

• Corrected the handling of uint32 and fixed32 types in protocol buffers to ensure that they work with numbers as large as 2^32 - 1, which is larger than an integer can hold in R since R does not have an unsigned integer class. These values are stored as doubles internally now to avoid losing precision.

• Added unit tests to verify behavior of RProtoBuf with extreme values for uint32 types.

• Removed old exception handling code and instead rely on the more modern Rcpp::stop method maintained in Rcpp.

• Add better error messages when setting a repeated field of messages to inform the user which element index was of the wrong type and what the expected type was.

• Add an optional 'partial' argument to readASCII allowing uninitialized message fragments to be read in.

• (internal) Added const qualifiers in more places throughout the C++ code for type safety.

• (internal) Standardize coding conventions of the C++ files and run them through clang-format for consistency. A STYLE file has been submitted to R-Forge with details about the coding standards and how they are enforced with Emacs and clang-format.

• Applied changes suggested by Kevin Ushey to the S4 class handling to support both the currently released Rcpp as well as the currently pending next version.

Changes in RProtoBuf version 0.3.2 (2013-12-15)

• Fixed a bug that erroneously prevented users from setting raw byte fields in protocol buffers under certain circumstances.

• Give a user friendly error message when seting an extension to a message of the wrong type instead of causing a C++ check failure that terminates the Rsession.

• Change object table lookup slightly to allow users to use the <<- operator in code using RProtoBuf without hitting a stop() error in the lookup routine.

• Add missing enum_type method and improve show method for EnumValueDescriptors.

• Improve documentation and tests for all of the above.

• Rewrote tests/ script calling RUnit tests

Changes in RProtoBuf version 0.3.1 (2013-09-13)

• Added support for setting and getting 64-bit integer types as character strings of decimal integers to work around R's lack of native 64-bit integer types.

• Added better error handling, documentation, and tests to the extensions support (getExtension and setExtension).

• Add support to P for returning extension descriptors.

• Improved error messages to include field names when invalid fields are specified to protocol buffer messages with new, update, etc.

• Improved configure to detect and pass -std=c++0x if it is available to enable long long 64-bit integer support in Rcpp.

• Improved configure in the case when pkg-config is not available or does not know about the google protocol buffer includes.

• Replaced newly deprecated Rcpp macros with a simplified macro functionality to avoid warnings on the latest development version of Rcpp.

Changes in RProtoBuf version 0.3 (2013-07-13)

• Added support for Protocol Buffer extensions through the new getExtension and setExtension methods for Message objects, and added top-level extensions to the descriptor pool.

• Added more user-friendly show() methods for Messages, Descriptors, and other RProtoBuf objects. A common source of confusion on the mailing lists is to confuse Messages and Descriptors. The new show() methods succinctly display more information about e.g. the number of set fields in a message to make it a little clearer to users what type of object they are working with.

• Added has method for EnumDescriptor objects to test existance of a named constant in an enumeration, and fix a bug in the length method for these objects.

• Added a number method for EnumValueDescriptor objects to return the number of a named enumeration constant directly.

• Improved documentation and unit tests.
