Revision history for Neo4j::Driver

0.36  2023-02-05

 - Add support for managed transaction functions.

   available to plug-ins as a Neo4j::Error object. (GH #7)

0.35  2023-01-24

 - Fix an issue which could cause a Bolt v3/v4 session to report
   "Bolt error -1" and become unusable after a server-side statement
   evaluation failure inside an explicit transaction.

0.34  2023-01-22

 - Refactor experimental plug-in API:
   - Rename PluginManager to Events, add_event_handler() to add_handler(),
     trigger_event() to trigger().
   - Specify behaviour of HTTP adapters for internal error responses generated
     by the network library.
   - Deprecate adding plug-ins by module name; use plug-in instance instead.
