Flex UI minor version End of Life reference
Start by logging into Flex and visiting the version management page. Here you will see the current version you are on, and whether automatic upgrades are enabled. We encourage all customers to enable this feature.
If automatic minor version upgrades are enabled, you’ll be kept on a Supported or Maintained version. The upcoming End of Life of minor versions will not affect you.
If automatic minor version upgrades are not enabled, check the currently installed version for your account and use the following table to understand how the End of Life will affect you and what action you should take.
When checking your version, you can ignore the third number after the second period, known as the patch version. For example, if your version is 1.33.2 you can ignore the .2 patch version number at the end. Your version is 1.33.
