-==== [CONJ-398] Improve deadlock debugging capabilities
+#### [CONJ-398] Improve deadlock debugging capabilities
MariaDB has now 2 new options to permit identifying deadlock :
New options
-|=includeInnodbStatusInDeadlockExceptions|add "SHOW ENGINE INNODB STATUS" result to exception trace when having a deadlock exception.\\//Default: false//
-|=includeThreadDumpInDeadlockExceptions|add thread dump to exception trace when having a deadlock exception.\\//Default: false//
-==== [CONJ-639] the option "enabledSslProtocolSuites" now include TLSv1.2 by default
+|Option|Description|
+|---|---|
+|includeInnodbStatusInDeadlockExceptions|add "SHOW ENGINE INNODB STATUS" result to exception trace when having a deadlock exception.
//Default: false|
+|includeThreadDumpInDeadlockExceptions|add thread dump to exception trace when having a deadlock exception.
Default: false|
+
+#### [CONJ-639] the option "enabledSslProtocolSuites" now include TLSv1.2 by default
previous default value was "TLSv1, TLSv1.1", disabling TLSv1.2 by default, due to a corrected issue (MDEV-12190) with servers using YaSSL - not openSSL. Server error was .
Now, the default value is "TLSv1, TLSv1.1, TLSv1.2". So TLSv1.2 can be use directly.
Connecting MySQL community server use YaSSL without correction, and connection might result in SSLException: "Unsupported record version Unknown-0.0".
-==== [CONJ-642] disable the option "useBulkStmts" by default
+#### [CONJ-642] disable the option "useBulkStmts" by default
Using useBulkStmts permit faster batch, but cause one major issue : Batch return -1 = SUCCESS_NO_INFO
Different option use this information for optimistic update, and cannot confirm if update succeed or not.
This option still makes sense, since for big batch is way more faster, but will not be activated by default.

-* [CONJ-639] enabledSslProtocolSuites does not include TLSv1.2 by default
-* [CONJ-641] update maven test dependencies for java 10 compatibility
-* [CONJ-643] PreparedStatement::getParameterMetaData always returns VARSTRING as type resulting in downstream libraries interpreting values wrongly

Evolutions:
-==== [CONJ-522] Pool datasource implementation
+#### CONJ-522 - Pool datasource implementation
MariaDB has now 2 different Datasource implementation :
* MariaDbDataSource : Basic implementation. A new connection each time method getConnection() is called.
* MariaDbPoolDataSource : Connection pooling implementation. MariaDB Driver will keep a pool of connection and borrow Connections when asked for it.
New options
-|=pool|Use pool. This option is useful only if not using a DataSource object, but only connection object. \\//Default: false. since 2.2.0//|
-|=poolName|Pool name that will permit to identify thread.\\default: auto-generated as MariaDb-pool-//since 2.2.0//|
-|=maxPoolSize| The maximum number of physical connections that the pool should contain. \\//Default: 8. since 2.2.0//|
-|=minPoolSize| When connection are removed since not used since more than "maxIdleTime", connections are closed and removed from pool. "minPoolSize" indicate the number of physical connections the pool should keep available at all times. Should be less or equal to maxPoolSize.\\//Default: maxPoolSize value. Since 2.2.0//|
-|=poolValidMinDelay| When asking a connection to pool, Pool will validate connection state. "poolValidMinDelay" permit to disable this validation if connection has been borrowed recently avoiding useless verification in case of frequent reuse of connection. 0 meaning validation is done each time connection is asked.\\//Default: 1000 (in milliseconds). Since 2.2.0//|
