Toast POS, like all apps, is an evolving product. Our engineering team works hard to improve features and functionality of the application to enhance our customers' everyday use of our product. When bugs are fixed, existing features are updated and new features are available a new version is released to be downloaded and installed on each Toast device/tablet.
Since different restaurants have different schedules, Toast allows you to schedule your upgrade when it is convenient for you. Generally there will be a week long period during which you can do your upgrade.* If you choose to not schedule your upgrade or forget, your Toast tablets will be automatically be upgraded at the end of the upgrade period.
You will be notified of an upcoming upgrade in two different ways. First, if you are on the Release Notes contact list for your restaurant, you will get an email describing the changes, and in that email there will be a link to schedule your upgrade. Second, if there is an upgrade available you will see an alert like shown below at the top of your Toast home page.
Either way, when you click on the link you will be taken to a page that looks like the screenshot below. To schedule your upgrade, fill in the date and time you want the upgrade (within the update period), and click 'Save'.
Once you've scheduled your upgrade, there is nothing else for you to do to until the time of the update. At that time, Toast will automatically push the upgraded application to your tablets. For security reasons, you will still need to tap the upgrade button on the screen that pops up on each tablet.
If you make a mistake or decide to change your upgrade time, you can do so through the reminder that appears at the top of your Toast home page, as shown below.
* Note that in rare situations it may be necessary for Toast to push out an update without giving significant advanced warning, e.g. if a security update had to be released or for some other high priority fix
