What is Your Policy on Updates and Upgrades
All updates to the same version of fmSMS are free. For example if you purchased v4.x of fmSMS you will be able to download any updates to v4 that we subsequently release for free. Updates might include new API examples or adding support for additional SMS Gateways. We also make changes based on customer feedback/requests for new features and examples.
When a new version of fmSMS is released you can download this using the download link from your original order confirmation email - that link will always download the most recent version. You can use a FileMaker developer tool like BaseElements or FMPerception to generate a comparison report between your original version of fmSMS and a later update to identify the elements that have changed and need updating (we can also produce one of these using BaseElements for you if required).
If we release a new major version of fmSMS this will be a paid upgrade. For example if you purchased v4.x of fmSMS and we release v5 and you wish to upgrade to that version you will be able to upgrade to this for a significant discount. All customers will receive a discount coupon from us to use for upgrading to a later version when it is released.
