This release includes a number of new features that are breaking changes with respect to v1.1.

• DyNet no longer requires boost (thanks @xunzhang)! This means that models are now not saved in Boost format, but instead a format supported natively by DyNet.
• Other changes to reading and writing include the ability to read/write only parts of models. There have been a number of changes to the reading/writing interface as well, and examples of how to use it can be found in the "examples". (#84)
• Renaming of "Model" as "ParameterCollection"
• Removing the dynet::expr namespace in C++ (now expressions are in the dynet:: namespace)
• Making VanillaLSTMBuilder the default LSTM interface #474
