You now have more flexibility in how Hot Starts pools are created. What's new: 

• Scope pools to a specific invite - so only invited users can claim pre-warmed sandboxes;
• Select which tracks in an invite need hot starting and remove the ones that don't;
• Pool by sandbox preset – in the invite-scoped Hot Starts, you can now create one pool that covers all tracks using the same preset, instead of multiplying per track.

This update applies to all newly created pools and invites – existing ones are not affected. Smarter pools, less waste! Check out the updated documentation for the full walkthrough.
