How does a partial rollout actually work?

Hi. Thanks in advance for any clarification or experiences you can share.

Hoping to get a response from Simeon as well, please.

How does a partial rollout actually work?

• 5% of new installs get the new version?
• 5% of existing installs are automatically updated?
• Both?

Same question asked in a different way. When a partial rollout occurs, what ultimately triggers the new partially-rolled-out version being given to new user installations?

Partial rollout only affects the update of existing installations. New installations always get the latest version.

For example:

If you set 5% rollout, then 5% of existing installations will be updated to the new version.

New installations, on the other hand, will always get the new version.
