Media Creation Tool

What's new in this version:

New features and enhancements:
Transactions:
- You can use the following new script steps to commit or revert all changes in a transaction together. A transaction consists of changes to one or more records in the current window. Transactions support creating new records, editing records, and deleting records.
- Open Transaction: Starts a transaction; subsequent record changes are held in the transaction until a Commit Transaction or Revert Transaction script step is performed
- Commit Transaction: Saves all record changes and ends the current transaction
- Revert Transaction: Returns all records changed in the transaction to their original state and ends the current transaction

Functions:
- The new Get(TransactionOpenState) function returns 1 (true) if called within an open transaction; otherwise, it returns 0 (false)
- The new Get(CurrentTimeUTCMicroseconds) function returns the current time in Coordinated Universal Time (UTC) to the nearest microsecond
- The Get(LastExternalErrorDetail) function is renamed to Get(LastErrorDetail) and additionally returns the text of transaction error information, including script name, step name, and line number when it is evaluated after a Commit Transaction script step
- The new Get(LastErrorLocation) function returns the location of errors that are returned by the Get(LastError) function

Updated libraries:
- The jsonCPP library has been updated to version 1.9.5
- The ChartDirector library has been updated to version 7.0
- OpenSSL has been updated to version 3.0.7

General:
- The Show sign-in fields even when OAuth or AD FS is enabled file option is now enabled by default for newly created files
- Context menus for interactive container fields can now be disabled in the Inspector's Data tab in the Data Formatting area
- In Preferences in the General tab, you can now delete cached temporary files
- The new Tools menu > Create Add-on command allows you to create an add-on without using the Save a Copy as Add-on Package script step. This command lets you specify information about the add-on, creates the add-on package, and saves it where you can then install and use it in an app. This feature is incomplete but available for preview and should only be used for testing purposes.

To create an add-on with this command:
- In Layout Mode, name the layout "__FMAddOnTemplateDirectives_en"
- Select multiple objects on the layout
- Choose Arrange menu > Group
- With the group selected, choose Tools menu > Create Add-on

Addressed issues:
Windows:
- When using the Insert from URL script step and the --cookie-jar cURL option, the cookie data was not returned
- When custom apps contained more than 255 layouts, navigating to a layout with an ID greater than 255 caused the last layout in an app to load instead of the expected layout. The limit is now 1020 rather than 255.
- The Insert from a URL script step failed when using a cURL option with the LDAP protocol
- Rendering performance was slower than in FileMaker Pro 18
- In the Script Workspace, importing a script containing errors when no script was open caused two script tabs to open and could cause the application to close unexpectedly if the script was deleted or the script tabs were closed
- FileMaker Pro intermittently quit unexpectedly when dragging files to a web viewer
- Container fields set to automatically play audio or video were not automatically playing
- Button parameters incorrectly displayed only the value of the first parameter when you changed the value in one button and navigated to the next button using the Button Bar Setup dialog box
