+**2.6.4**
+* Fix several memory leaks and uninitialized fields using valgrind analysis (native and w/ JVM)
+  - BTGattHandler::disconnect(): Check weak BTDevice before using resources
+  - BTGattHandler::l2capReaderEndLocked(): Remove off-thread BTDevice::disconnect() on io-error, use BT host's disconnect (simplify tear down)
+  - BTGattHandler's l2capReader data race (use after free)
+* Trial `TestDBClientServer1*` test changes
+  - Split tests into NoEnc, SC0 and SC1 classes
+  - Have client/server adapter names unique, allowing multi-machine testing in one room
+* Bump jaulib v0.8.0
+* BTAdapter Server: Offload waiting for L2CAP client connection to BTDevice::processL2CAPSetup() dedicated thread
+* [L2CAP, HCI]Comm: Hold external interrupted delegate from `service_runner` for complete interrupted() query
+* WIP: BTAdapter::startDiscovery(): Retry up to `MAX_BACKGROUND_DISCOVERY_RETRY` (3), mitigating failure to start discovery
+* BTDevice::notifyLEFeature(): Remove HCIStatusCode param and only call with SUCCESS status code
+* Fix and [document default connection paramter](doc/Connection_Parameter.md), leaning to the higher performance side
