We’re happy to announce that macOS - 2021.10 & Linux - 2021.10 build stacks with Node 16 LTS and npm 8.1.0 support will be tagged as the Latest build stacks in Appflow from today. Additionally, the Linux - 2021.10 also includes support for Android SDK 31 build tools to target the recent Android 12 release.
Please note that this would automatically update any automation that you have set to “always use the latest build stack”. If you would like to use a different build stack you must manually choose from the build stack dropdown when performing a build or setting up (or editing) the automation. Refer to our docs on Build Stacks in Automations.
