You can now match attribute values based on what they start or end with:

A few ways this could be useful to you:

• If you have a set of attribute values that all start with the same beginning, such as pro-2020, pro-2021 etc., you can now match them in one go.
• To randomize whether a flow starts, you could use something like "User ID ends with 1". Assuming your IDs are numeric, it'll randomly match 10% of your users.
