# Changes
+## v1.3.0
+
+* Query options:
+ - Adds the support of providing query options (optimizer version) via
+ three ways (precedence follows the order):
+ `client-level < environment variables < query-level`. The environment
+ variable is set by "SPANNER_OPTIMIZER_VERSION".
+* Connection pooling:
+ - Use the new connection pooling in gRPC. This change deprecates
+ `ClientConfig.numChannels` and users should move to
+ `WithGRPCConnectionPool(numChannels)` at their earliest convenience.
+ Example:
+ ```go
+ // numChannels (deprecated):
+ err, client := NewClientWithConfig(ctx, database, ClientConfig{NumChannels: 8})
+
+ // gRPC connection pool:
+ err, client := NewClientWithConfig(ctx, database, ClientConfig{}, option.WithGRPCConnectionPool(8))
+ ```
+* Error handling:
+ - Do not rollback after failed commit.
+ - Return TransactionOutcomeUnknownError if a DEADLINE_EXCEEDED or CANCELED
+ error occurs while a COMMIT request is in flight.
+* spansql:
+ - Added support for IN expressions and OFFSET clauses.
+ - Fixed parsing of table constraints.
+ - Added support for foreign key constraints in ALTER TABLE and CREATE TABLE.
+ - Added support for GROUP BY clauses.
+* spannertest:
+ - Added support for IN expressions and OFFSET clauses.
+ - Added support for GROUP BY clauses.
+ - Fixed data race in query execution.
+ - No longer rejects reads specifying an index to use.
+ - Return last commit timestamp as read timestamp when requested.
+ - Evaluate add, subtract, multiply, divide, unary
+ negation, unary not, bitwise and/xor/or operations, as well as reporting
+ column types for expressions involving any possible arithmetic
+ operator.arithmetic expressions.
+ - Fixed handling of descending primary keys.
+* Misc:
+ - Change default healthcheck interval to 30 mins to reduce the GetSession
+ calls made to the backend.
+ - Add marshal/unmarshal json for nullable types to support NullString,
+ NullInt64, NullFloat64, NullBool, NullTime, NullDate.
+ - Use ResourceInfo to extract error.
+ - Extract retry info from status.
