Release Notes

* 1.37    - Reuse StringBuilder instances when possible (list parameters in particular)
      * 1.36    - Fix Issue 192 (expanded parameter naming glitch) and Issue 178 (execute reader now wraps the command/reader pair, to extend the command lifetime;
      *          note that the underlying command/reader are available by casting to IWrappedDataReader)
      * 1.35    - Fix Issue 151 (Execute should work with ExpandoObject etc); Fix Issue 182 (better support for db-type when using `object` values);
      *          output expressions / callbacks in dynamic args (via Derek); arbitrary number of types in multi-mapping (via James Holwell);
      *          fix DbString/Oracle bug (via Mauro Cerutti); new support for **named positional arguments**
      * 1.34    - Support for SqlHierarchyId (core)
      * 1.33    - Support for SqlGeometry (core) and DbGeometry (EF)
      * 1.32    - Support for SqlGeography in core library
      * 1.31    - Fix issue with error message when there is a column/type mismatch
      * 1.30    - Better async cancellation
      * 1.29    - Make underscore name matching optional (opt-in) - this can be a breaking change for some people
      * 1.28    - Much better numeric type conversion; fix for large oracle strings; map Foo_Bar to FooBar (etc); ExecuteScalar added; stability fixes
      * 1.27    - Fixes for type-handler parse; ensure type-handlers get last dibs on configuring parameters
      * 1.26    - New type handler API for extension support
      * 1.25    - Command recycling and disposing during pipelined async multi-exec; enable pipeline (via sync-over-async) for sync API
      * 1.24    - Implement pipelined async multi-exec, when flag is specified (only - requires MARS etc)
      * 1.23    - Improved support for optimize hints (@foo unknown) with list expansions
      * 1.22    - Literal support now extends to enumerable types (for "in" etc usage); move to command-flags model for "buffered" etc
      * 1.21    - Limit literals to numeric types; for enums, use value not name
      * 1.20    - Improved async support in .NET 4.5 (lots of contributions from users here, including JasonPunyon, kwaclaw, tugberkugurlu, and mgravell);
      *          Now supports literal replacement via {=foo}; new ExecuteReader method (via JJoe2); support for ICustomQueryParameter
      *          dictionary members (via Blackjacketmack); culture sensitivity (via tms); fixes for time parameters (via olegKoshmeliuk);
      *          and a range of additional tweaks, twiddles, fixes and improvements.
      * 1.13  - Added support for Table Valued Parameters as part of anonymous objects
      *        - Added support for async
      *        - Added support for sharing strategies between databases
      *        - Rewrote dynamic implementation
      * 1.12.1 - Minor deploy glitch (should now include intellisense files!)
      * 1.12  - Better automatic type-mapping (int vs long, float vs double, etc)
      *          Fixed: bug with indexer properties
      * 1.11  - Custom type-map support
      * 1.10  - Fixed: error-handling could lose original exception if reader closed
      * 1.9    - Added: better schema change detection
      *          Fixed: enum support for T in Query-of-T
      *          Added: dictionary support for parameters
      * 1.8    - Started release notes
      *          Important: Dapper is now shipping as a DLL which will work on .net 3.5 or .net 4.0,
      *          This improves the debugging experience as you no longer break into dapper when SQL fails.
      *          Added: ParameterNames on DynamicParameters
