Version 3.0.0, released 2020-04-15

Version 3.0.0-beta01, released 2020-02-18

This is the first prerelease targeting GAX v3. Please see the breaking changes guide for details of changes to both GAX and code generation.

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
