• Fixed issues with Transaction#isOpen() that could incorrectly report transaction as being closed #374 and #375

• Throw ServiceUnavailableException instead of ClientException when socket write fails #312
• Updated routing logic to follow specification #314
• Throw AuthenticationException instead of ClientException when connection fails due to authentication error #315
• Fix InternalRecord#hashCode() #320

• Improved API docs #306
• ServiceUnavailableException if failed to read from the server both for encrypted and unencrypted connections. #issue302 #304
• Added osgify artefact MANIFEST.MF by community contributors #284
• Always waiting for bookmark when starting a transaction #303
• Configurable test-on-borrow for pooled connections, which introduces a configurable connection liveness check timeout to ensure that the connection obtained from the connection pool is alive. issue#144 #297

• Removed finalize from NetworkSession, while added ConfigBuilder#withLeakedSessionsLogging to allow a application developer to switch to a Session implementation that supports logging in finalize for session leak investigation in his/her application. #285
• Improved handling of concurrent driver close. #291

• Fixed the bug where the driver.close might fail to close connections that are still in use.
• Fixed the bug where the connection is not closed if fails to INIT with server.
• Fixed the bug where connection pool might not be closed if driver creation fails.

• Removed read and write locks in Driver class so that driver.close does not need to wait for all other threads to release read locks. #286
• Added more logging around routing table changes #287
• Fixed off-by-one error in max routing failures #288

• Close all connections on driver.close() #252
• Move all server information accessing methods such as server version and server address into ResultSummary#server #272
• Add StatementResult#summary to pull all unconsumed records into buffer and yield the result summary 275
• Improvements on trust mode. Introduced TRUST_ALL_CERTIFICATES as the default trust mode, deprecated TRUST_ON_FIRST_USE and removed ENCRYPTION_NON_LOCAL. Also TRUST_ON_FIRST_USE is disallowed with bolt+routing scheme #268
• Made it configurable to retry a few times with a delay after fatal routing failures #259 #264
• Fix the bug where the tx is not rolled back if the result is not consumed. #276

• Proper handling of cluster failures for transactions #250
• Fixed expect strut but get xx bug #249

• Minor code refactoring.

Bug fixes for discovery and routing:

• Fixed the bug where a server is not removed when failing on session acquisition #241
• Fixed the bug where a server is not removed when failing to write on the server #243
• Fixed the bug where the same connection would be put back in the pool twice after discovery #244

• More friendly error when user tries to WRITE in a READ session #234

• Introduced Bookmarking for read your own writes in a 3.1+ Neo4j cluster #223
• Added session#reset to stop long running statements in the current session #210, #211, #231
• Replaced TRUST_SIGNED_CERTIFICATES with TRUST_SYSTEM_CA_SIGNED_CERTIFICATES and/or TRUST_CUSTOM_CA_SIGNED_CERTIFICATES #218
• Supported for custom auth-tokens #221
• Exposed resultAvailableAfter and resultConsumedAfter on ResultSummary and server on Session #219
• Added new API for accessing records and mapped values with a default value #172

Bug fixes:

• Better handling of BUFFER_OVERFLOW on writes for TLS connections #177
• Reduce long time memory usage #207
• Tidied up format of log messages [#204] (https://github.com/neo4j/neo4j-java-driver/pull/204)
• Prefer Map over iterable in Values#value method #208

• Added EncryptionLevel.REQUIRED_NON_LOCAL as default encryption level #191
