# November 6, 2025

This is a small update that includes some enhancements and stability improvements.

* Several new workflow enhancements have been added.
  * **Added an "absolute value" function to the "math" workflow node parameter type.** This allows users to use the `abs()` function to take the absolute value of a number, converting for example `-12.13` to `12.13`.
  * **Added the "construct datetime" node parameter type.** This allows users to create datetimes in a particular time zone, from date and time parts. 
  * **Added the "construct date" node parameter type.** This allows users to create a date from a string. This is a nice addition to the current "date" node parameter type, which only allows users to select a hard-coded date.
  * **Added the "time" node parameter type.** This allows users to pick a time using a time widget.
  * Added several options related to time: You can now convert a datetime to a time, stripping it from of its date. This can be used with the "construct datetime" node parameter type to create a new datetime from this time. You can also compare times.
* Fixed an issue where Middle backend workers could crash due to running out of memory in the following situations
  * when building large files as part of an export file step
  * when saving a lot of records (hundreds) when each record had a lot (hundreds) of foreign keys to other objects
* Fixed a workflow system error that could occur if a Workflow timedelta node parameter was given a null value
