Version 2.1.0, released 2019-12-12

Commit 0740a76: Adds support for retriable transactions
Transparent support for batch creation of sessions (to make session creation more efficient)

Version 2.0.0, released 2019-06-03

New features:

Batch query support
Connection string option to enable SpannerDataReader.GetSchemaTable() to return schema information
DML and PDML support
Batch DML support
Session label support

Breaking changes:

Many aspects of configuration have changed. Please refer to the configuration guide, migration guide and connection string options for more details.
Null values are returned as DBNull.Value by default rather than the CLR default value for the type. Array and struct elements use a null value where feasible, but throw InvalidCastException when requested to be converted to a non-nullable value type. The 1.0 behavior can be requested using the UseClrDefaultForNull connection string option.
Hashtable is no longer used as a default type for struct values. It can still be specified explicitly. The new default is Dictionary<string, object>.
The libraries no longer target netstandard1.5; only netstandard2.0 and net45 are supported

Version 1.0.0, released 2017-12-05

Initial release.
