RELEASE NOTES VERSION 1.4.2¶

Version 1.4.2-38¶

Released: 23 January 2026

Optimized data refresh in Rulex Studio: Data refresh now checks for last modification date of those datasets originating from files. This prevents unnecessary reloads. (Linked issue: RP-5241)
Added logging of host in Azure Blob Storage: Added logging of host for Azure Blob download and upload operations. (Linked issue: RP-5253)

Wrong structure data in rulex logs: Fixed a corner case in which the log metadata were not emptied if an error would have occurred in flow preparation. This bug caused logs to repeat metadata at each entry. (Linked issue: RP-5236)

Released: 19 January 2026

Timeout in B&S doesn’t work: Handled empty input dataset in BuildSolve task. (Linked issue: RP-5231, CS-4114)
Fixed Rare Batch Startup Error: Resolved a rare startup issue in batch mode where the working database connection might not have been correctly established. (Linked issue: RP-5251)

Released: 14 January 2026

Added retry when trying to create a zip file: Added retry when trying to create a zip file. The system performs 4 attempts before raising an error. (Linked issue: RP-5239)
Add progress when loading a flow: Introduced progress bar when loading a flow (Linked issue: RP-5242)

UNKNOWN INTERNAL ERROR - BUG ACCENTED LETTERS: Introduced regex to check name for new variables in order to accept letters, numbers, and _ characters only. (Linked issue: RP-5228)
Preceding task is not being computed but flow would still complete successfully: Fixed the lock mechanism operating when two users tired to open a flow at the same time. (Linked issue: RP-5237, CS-4092)
Exported RFL is missing some variable values: Fixed a bug occurring when a flow having sensitive environment variables was exported. (Linked issue: RP-5244, CS-4123)

Released: 07 January 2026

Branch Variable can not be used in task Execute Rulex Flow File as iterator: Fixed a bug which prevented users from using branch variables as iterators in module tasks. (Linked issue: RP-5225)

Released: 19 December 2025

Released: 18 December 2025

Added authentication token storage and usage as branch variables: Supported storing and using authentication token as branch variables for OAuth2. (Linked issue: RP-4765)
Implemented possibility to add to your current View datasets derived from other Views in Rulex Studio: Implemented possibility to add to your current View datasets derived from other Views in Rulex Studio. (Linked issue: RP-4961)

Add new parameter to round function: Added a new parameter called nprecision to the round function to control the number of decimal digits which will be maintained in the operation. (Linked issue: RP-4974)
Studio: Made table relations editable by user: Relations between tables were automatically deduced according to attribute names. They can now be optionally set by the user. (Linked issue: RP-5114)
Changed how to determine available memory for Ubuntu, RHEL and Darwin: In Linux systems, Rulex Platform now reads MemAvailable instead of MemFree to determine how much memory is available to use. Darwin memory check was fixed similarly. (Linked issue: RP-5131)
Integer Plot range has been adapted to show even spaces: In Plots with integer values on axis, ticks should have been displayed only on integer points. This led to showing unevenly distributed ticks. Drawing operation has been updated to automatically adapt axis range to reach both the goals. (Linked issue: RP-5182)
Add batchFailPolicy for Batch mode: Added ‘batchFailPolicy’ flag to batch mode to control behavior on command failure when executing multiple commands from a batchFile. Supported values are ‘continue’ (default, execute all commands) and stop (stop on first non-zero exit code). (Linked issue: RP-5218)
Overhauled Rulex Studio actions: Studio actions have been refactored to manage better user value modifications, aligning its behavior to Studio inputs (Linked issue: RP-5219)

Progress bar stalls at 50% during Flow computation: Improved progress calculation for small-flow computations. (Linked issue: RP-2522)
Ticks are disproportionate when the bar plot has an integer attribute with None values: Changed the way ticks are evaluated in case of integers and date/time columns. Now range is adapted to have equally spaced ticks, appearing in correct integer quantities. (Linked issue: RP-3633)
