This version will include several bug fixes.
Additionally with this version it should be possible to select local packages during the installation process.

This version contains performance improvements and bug fixes.

• added out-of-license message with configurable threshold
• added possibility to execute configurable batch file, once license threshold is reached
• added license restore support
• support of license name instead of only product codes

This version prepares the transition to version 5.0: It provides unbound-placeholder resolution for the Memory Block Manager library of CODESYS. This allows for add-ons and for projects that can safely switch between Base Libraries 4.0.1 and 5.x.

Fixes issues with exception handling in IEC code. This is required to resolve issues with using OPC UA and BACnet on devices with LoongArch CPUs.

This version contains bug fixes and some small additions to existing scripting drivers.

This version contains several Bug-Fixes.

This version introduces the new, application-based subscription licenses that can be updated via the Store. It also includes maintenance of Persistance Manager (15), DataLog Manager (5) and others (11).

Maintenance release with bug fixes.

This version contains several bug fixes including

Refactoring:

• Dialog shows wrong places of changes in page-oriented CFC
• Renaming an FB instance leads to rename of box type

Project Update:

• When updating a project from SP16P9 (CFC 4.2.0.0) to newer versions like SP19P4 or SP20P2 (CFC 4.3.0.0 / 4.4.0.0), the alignment of boxes (inputs/outputs) and connecting links changes unexpectedly due to the introduction of the "Hide namespaces" feature

This version optimizes the treatment of 7bit-ASCII-only strings and simplifies the exchange with classic string functions by an internal terminal null.

Contains a fix for issues with the TEST_AND_SET operator not working reliably.

Issues with jumps in very large POUs on ARM Cortex targets are fixed.

This release includes usability improvements.

Analysis results can be exported in the SARIF format which allows to view and process it in third party tools and CI workflows.

Adjustment of the execution order within a network. 
In this version, the execution order within a network is the same as in LD FBD.

Preview version of the Simulation Interface for evaluation and integration in simulation tools (please contact sales): The Simulation Interface integrates CODESYS applications into machine simulations (Software-in-the-loop) by a toggle switch using OPC UA mechanisms.

This version contains bug fixes and minor improvements.

Maintenance release containing bug fixes and usability improvements.

This version contains bug fixes and minor improvements.

Last maintenance release before start of the service phase.

Created the possibility for device manufacturers which use their own licensing mechanisms for the engineering environment to integrate the CODESYS Professional Developer Edition into their systems.

This version contains bug fixes and improvements.

This version contains several bug fixes and minor improvements.

The usage of the memory tools is supported for core dumps.

This version contains bug fixes and minor improvements.

This release fixes the problem that projects may get modified on opening, when they use libraries from Inspection-supporting library addons (currently CODESYS Base Libraries, CODESYS String Libraries).

This is a maintenance release fixing known issues for the usage of packed data structures. Furthermore, the usage of the FPU can be disabled explicitly for devices.

Improved support for Clang / LLVM EABI

Improved support for Clang / LLVM EABI.

Fixed issues in certain cases when using pack_mode attribute on ARM based devices.

Update of "CODESYS Application Composer Single License" only, no functional changes. This update is necessary for running "CODESYS Application Composer" (any version) in SL-mode on any new CODESYS versions starting with V3.5 SP19 Patch 3. It cannot be used with older CODESYS versions. For using "CODESYS Application Composer" with older CODESYS versions, use the old "CODESYS Application Composer Single License".
