    The developers of CUBRID have done a great job in improving the performance and stability of the DBMS. According to the results of quality assessment tests, the performance of INSERT and UPDATE operations increased by more than 70% (see table below).

    Also, thanks to numerous requests, we have added many new functions and support for additional SQL syntax for even more compatibility with MySQL. In addition, the new version of the DBMS has added support for regular expressions in the operator WHEREfor a clearer declaration of search conditions, as well as new broker parameters and improved system monitoring. In total, about 50 errors were fixed in the new version.

    Below I will list the main innovations in version 8.4.1.

    As a result of all this, the performance of INSERT and UPDATE operations in version 8.4.1 has increased dramatically by more than 70% compared to the previous version 8.4.0.

    The following table shows the output of the quality assessment obtained as a result of tests conducted on versions 8.4.0 and 8.4.1.
