Release history

Development Environment (DT):

The changes included in this new release may not be immediately noticeable to most users, as they primarily affect the underlying architecture rather than visual components. However, despite their subtle nature, these enhancements will significantly streamline workflows, particularly for teams working on large-scale automation and dispatching projects. The key improvements focus on the development environment's project structure.
The development environment project is essentially a database storing elements, their relationships, property values, and all user modifications. Previously, when graphical elements were added to windows, their modified properties were automatically created as parameters in the full tree or window legend, regardless of whether they had active connections.
In version 1.3.8, we've optimized graphical element handling. Parameters are now only created in the database when actual connections exist. Property values without connections are preserved as element attributes instead.
Additionally, we've redesigned how window events (Mouse Click, Mouse Press, Focus Loss, etc.) are managed. Rather than automatically adding all events to the project upon window creation as before, events are now manually created only when needed through the window properties panel.
We've optimized how value conversion settings are stored for graphical elements while maintaining copy/paste functionality for conversion settings in window legends. We've also added one-click removal for configured conversions.
These architectural improvements result in significantly smaller project database sizes, which translates to faster development environment performance.
Important note: Once you convert a project to the new version, this change cannot be reverted. We strongly recommend accepting the system's prompt to create a backup before conversion.
The project structure optimization also enabled several secondary enhancements. Tabular project views now display scale and archiving template information more efficiently across different element types. CSV file import in tabular view has been simplified - files containing columns not displayed in the editor no longer require manual table adjustments.
The "Project/Check Project Integrity" procedure from the main menu now executes faster, with improved algorithms for handling detected issues.
For development-runtime environment interaction, version 1.3.8 introduces a new WebSockets protocol that supports large data structures and enables debugging of ANY-type parameters for arrays/structures.

Runtime System (RT):

Runtime environment management just got easier! We've released a universal cross-platform monitor. We introduced this new product several months ago as a beta version, and we thank everyone who participated in testing and provided feedback. You can review its features via this link. We've incorporated the primary user suggestions, and it now serves as the default monitor on both Linux and Windows operating systems. For Windows, it installs alongside the runtime environment, while on Linux, the runtime system installs independently from the monitor.
MasterSCADA 4D RT now operates on PLCs as well. We've balanced the need for data recovery after restarts with efficient resource utilization - the state preservation service configuration has become more flexible, offering options to save changes periodically, on-change, or only during runtime shutdown.
The state preservation service, redundancy, and every protocol added to a project now operate as independent runtime tasks. Version 1.3.8 removes the previous 256-task limit.
We've restored compatibility with newer MySQL database versions, including authentication method selection.
As always, we've enhanced multiple protocols. IEC 61850 now supports redundancy, while SNMP/SMS integrates notification delivery through standard network mechanisms (SMS, SNMP traps). The Modbus protocol received attention too, with support for non-standard byte orders.

Visualization Client:
