1.7 changelog

v1.7.0-beta02

This release adds support for Bolt V3. The transaction configuration API introduced in v1.7.0-beta01 is now fully functional when ran against a neo4j 3.5 version (currently pre-release).

The following features are introduced in Bolt V3;

• Both a transaction timeout and transaction metadata can be set with Session.BeginTransaction, Session.ReadTransaction and Session.WriteTransaction calls. These can be passed via variadic function arguments that mutates TransactionConfig struct - neo4j.WithTxTimeout and neo4j.WithTxMetadata are provided as part of driver API.
• All of these transaction configuration options are now also applies to Session.Run calls (which are wrapped in auto-commit transactions on the server side)
• Session.Run calls are now executed as part of the causal chain.

v1.7.0-beta01

This release doesn't add any features but introduces public API changes.

• Statement parameters map (params parameter) that is sent with Session.Run or Transaction.Run is now of type map[string]interface{} and not a pointer.
• All previous public struct types are converted into interfaces to support mocking for external testability. Also private functions on Driver interface are also removed for the same reason.
• CustomAuth function now takes its parameters parameter as of type map[string]interface{} instead of a pointer.
• Added API for transaction configuration which provides a means of setting transaction timeout and attaching transaction metadata to transactions on arbitrary explicit/auto-commit transactions. This is a placeholder functionality for now, underlying implementation will be introduced in upcoming releases.
• Improved API documentation.

v1.7.0-alpha4

Removed master branch and made 1.7 the default which will hold the long run stable 1.7 driver release (the same applies to downstream - gobolt and seabolt)

• Renamed seabolt wrapper from neo4j-go-connector to gobolt (accessible at https://github.com/neo4j-drivers/gobolt)
• Changed the package structure of the driver as per packaging guidelines and moved top level code into neo4j folder which can now be imported from github.com/neo4j/neo4j-go-driver/neo4j
• Made the logger provided to the driver through neo4j.Config to be used across the whole stack (now you can get more useful log entries from seabolt - especially when DEBUG log level is enabled)
• Added support for bolt+routing scheme to work against causal cluster deployments, yay! (all you need to do is to point your URL to bolt+routing://<hostname>:<port> where <hostname>:<port> pair points to one of the core servers in the cluster)
• Added support for specifying custom neo4j.ServerAddressResolver through neo4j.Config that can map <hostname>:<port> pair provided as part of the driver URL to multiple entries (i.e to provide all core server addresses) - so that all those mapped entries are tried in turn until routing table is fetched
• Renamed spatial type constructor function neo4j.NewPoint to neo4j.NewPoint2D for consistency
• Enabled SNI extension on TLS sessions

v1.7.0-alpha3

• Added support for all temporal and spatial types that were introduced by Bolt version 2 (introduced as part of server release 3.4)
• Added support for returning Path types as return values

v1.7.0-alpha2

• Fixed an issue where node and relationship values returned from a query was not accessible through driver

v1.7.0-alpha1

• The first release of the Neo4j Official Go Driver. It only includes support for Bolt V1 (which means you cannot use temporal / spatial types introduced with Neo4j database 3.4 version) and works only on direct mode (no clustering support)
