Version 5.13

Release Date: 1 November 2025

INFORMATION: Please read these release notes before updating.

INFORMATION: Before updating make a backup of your current settings.

CAUTION: Before updating, save a copy of your Printable File. Print this file and use it to verify your settings after the update is complete.

CAUTION: Version 5.13 uses a new settings format. Updating will automatically convert your existing settings to the new format. Do not load a settings file from version 5.12 or earlier into version 5.13, as this will corrupt the settings and cause MASSO to revert to default settings. Use the Printable File you created before updating to check and correct your settings after the update. Only use the backup you made before updating if you need to roll back to your previous software version.
