2. Precautions
 - It is not compatible with the volumes of previous versions (11.1 or less), so DB reconfiguration is required when upgrading to 11.2
 - By introducing the concept of user schema, the same object name can be used for each user. According to this support, "." (dot) is not allowed in object names, and --no-user-specified-name option is provided so that loaddb files before 11.2 can be performed in 11.2.
 - When another user accesses the table, it is necessary to include the user name in the table name after grant or use a synonym
 - When using “jdbc:default:connection:” or getDefaultConnection() of JavaSP, the behavior is changed, such as not supporting all functions of java.sql.DatabaseMetaData
 - The behavior of the TRUNCATE TABLE changed if there is set null or cascade of FK
 - Column properties not written during alter change/modify are changed to be maintained, and auto_increment and on update properties cannot be removed with the alter statement
 - Changed to handle an error if only the column name exists(UPDATE ... WHERE c1;) in the where clause
 - Multiple SQL must be separated by semicolons(;)
 - As the CCI Driver directory in the CUBRID package is changed, $CUBRID/cci/lib must be added to the environment variable LD_LIBRARY_PATH when using CCI.
 - Changed Compression (-z, --compress) option to default on backup
 - System catalog information changed or added due to the addition of new features
 - The driver version is managed separately from the CUBRID version. The driver version compatible with CUBRID 11.2 is 11.1

3. Environmental requirements 
 - Linux: 64bit, kernel 2.4 or higher, Windows: Windows7 or higher (Windows7 is needed the latest update patch) 
 - JRE 1.8 or higher is required when using JSP or CUBRID Admin/CUBRID Manager
