Since ConfiForms app version 2.x we publish release notes here 

Version 2.26.4

...

• Rendering: Fixed issue with accessing properties of the field when it is referenced through the smart field
• Rollback of "move attachment" IFTTT change due to incomplete implementation of possible user scenarious. Making it look broken when an attachment that is moved remains referenced in some field of a ConfiForms form

Version 2.26.3

• Fixed regression in filtering of masked field type values when the field is set to use "numeric" or "date" field type
• Fixed issue with double <br/> happening on comment fields when rendered
• Improved support for web-services backed fields that have ID as row identifier (that was incorrectly interpreted as a missing id for the ConfiForms record, as "id" is expected (in small letters))
• Improved ConfiForms Filter Control macro to work with "metadata" fields, like "created", "ownedBy", etc (on custom layouts) - Documentation
• Fixed issue with ConfiForms Filter Control and JavaScript that can be set to be executed on filter refresh
• Fixed performance issue with pages having Smart ConfiTemplates plugin used together with ConfiForms
• Fallback routine implemented to move an attachment via ConfiForms IFTTT to use saveAttachment/deleteAttachment methods to workaround issues cause with attachment reconciliation process (which happens with enabled collaborative edit)

  Important to note that this will only work on certain cases, when source page (where the form is) does not have other attachments or attachments with the same name (multiple versions of the attachment)
• Fixed security issue with copyAttachment/moveAttachment (proper access rights checks now implemented)
• Support for scientific notations in numbers - to be used with Supported math operators, formulas and functions
• Improved Persian calendar field to work correctly with time settings
