High Performance SDK V1.1.0
===========================

New Features:
-------------

* New Client SDK
* New UaApplication object for SDK initialization
* New OPC UA Binary File Format for Information Models
* New Platform support for Segger embOS and embOS/IP
* New Crypto and PKI backends for Mocana NanoCrypto library
* Generic structure encoder/decoder which allows to handle new types at
  runtime. This also reduces code size for all built-in types in NS0.
* New binary file format, which is now a serialized cross-platform file format.
  V1.0.0 used memory pool dumps which worked not across different hardware 
  platforms.
* New xml2bin tool which converts XML Nodeset files into the new binary file format.
* New xml2c tool which generates static address spaces. An addition to the address space C file
  it now also generates C code for all datatypes and type tables for the generic encoder/decoder.
 - New datatype "class" generation: C data structures and functions.
 - Support for enums, structures, structures with optional fields and unions.
 - Supports also inherited datatypes.
 - Type tables generation
 - CMake project generation to build complete libraries for type systems.
* New examples:
 - Sensor Model Server: Demonstrate usage of dynamic and static type systems,
   as well as type instantiation.
 - History Example Server: Demonstrates how to implement UA history and how to
   implement underlying protocols using the SDK's network API.
 - Client Getting Started Tutorial
 - HP SDK Sample Client
* More documentation

Bugfixes:
---------

We've fixed a large number of bugs found in V1.0.0 and improved the overall
performance and stability.

Breaking Changes:
-----------------

The Client SDK required to change the way the application gets initialized.
There is now a new 'uaapplication' object which must be created and which
initializes the SDK. This simplifies application initialization and works
for both client and server side. Please have a look into the examples/ folder
for an example.
