Updated Dimension Handling System

The logic for dimension handling has been significantly revised and improved. The most significant benefit of this update is improved error messages for dimension errors. Instead of just getting the dreaded Dimension Error message, some context about the operation or function that led to this error is included in the error message. This update also makes calculations faster in general, provides more robust handling of dimensions that are slightly different due to floating point rounding errors, and makes it easier to maintain and extend the dimension handling code in the future. This update is required to enable some significant new features that are coming your way!

Significant testing has gone into ensuring that this change does not introduce bugs. One change you may notice is that dimensions were sometimes lost in the past for dimensioned values that had zero magnitude. This should no longer happen but may lead to dimension errors for sheets that relied on the old behaviour. If you do notice a bug, please report the bug to [email protected] In the meantime, you may use the previous release's permalink (see the releases page) until the bug is fixed.

New Release Permalinks

New releases of EngineeringPaper.xyz roll out on a continuous basis. Because of this, if you go to the main EngineeringPaper.xyz site, you always get the most recent version with all of the newest features and bug fixes. This is also true for the alternative mirror addresses: epxyz.com and EngineeringPaper.com. Most of the time, this is what you want. However, there may be cases where you may want to use an specific release. If you find the updates distracting, using one of the release permalinks will allow you to avoid updates until you're ready. Additionally, in the event that a new version introduces a bug that is impacting your sheet, going back to a previous permalink will allow you to open your .epxyz file and keep working. Of course, if this happens, please report the bug to [email protected] so that we can get it fixed. A lot of effort is put into ensuring that new versions don't introduce bugs. However, a bug is always possible and ensuring that you're able to work with your existing sheets is a top priority.

For this, and all future releases, a permalink will be listed after the release date in this dialog (for this release, the permalink is: 20250116.engineeringpaper.xyz). This dialog can be accessed by clicking on the "Releases" entry in the left menu. The release permalinks will also be available on the EngineeringPaper.xyz GitHub site.

As you might expect, the introduction of permalinks is in anticipation of new releases coming your way. In the short term, most of the changes are related to updates to the internal structure of EngineeringPaper.xyz. These updates are important to modernize and simplify the code that backs EngineeringPaper.xyz and will pave the way for exciting new features in the future. Stay tuned!
