• New dirinst/python with some Python examples.

• Added Jeroen Ooms as author.

• Vignettes have been converted to the R 3.0.0 or later use ofexternal vignette builders, no longer need aMakefile

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

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

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

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

• Updated the FileDescriptorname() method to accept a booleanfor full paths just like the genericname() method.

• Correct a bug that incorrectly dispatchedas.character() whenas.list() was called on Descriptor objects.

• Update FileDescriptor$ dispatch to work properly forthe names of fields defined in the FileDescriptor, instead ofjust returningNULL even for types returned by$completion.

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

• Support setting int32 fields with character representationsand raise an R-levelstop() error if the provided string cannot be parsed as a 32-bit integer, rather than crashing the Rinstance.

• Update the project TODO file.

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

• Corrected the handling of uint32 and fixed32 types in protocolbuffers 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 anunsigned integer class. These values are stored as doubles internallynow to avoid losing precision.

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

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

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

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

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

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

• Applied changes suggested by Kevin Ushey to theS4class handling to support both the currently releasedRcpp aswell as the currently pending next version.

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

• Add missingenum_type method and improve show method forEnumValueDescriptors.

• Improve documentation and tests for all of the above.

• Rewrotetests/ script callingRUnit tests

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

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

• Added support for Protocol Buffer extensions through the newgetExtension and setExtension methods for Message objects, and addedtop-level extensions to the descriptor pool.

• Added more user-friendlyshow() methods for Messages,Descriptors, and other RProtoBuf objects. A common source ofconfusion on the mailing lists is to confuse Messages andDescriptors. The newshow() methods succinctly display moreinformation about e.g. the number of set fields in a message tomake it a little clearer to users what type of object they areworking with.

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