Sub ID and Advertiser ID slots expanded to 1-10

Sub ID and Advertiser ID slots expanded from 1-5 to 1-10. {sub6}-{sub10} and {adv6}-{adv10} are now valid macros in Partner Tracking Links and in Partner / Advertiser Postbacks. The expanded slots are also available as columns and filters in all reports (Click, Conversion, Impression, Dimensional, Flex, Offer) on both the Core Platform and Advertiser Platform, and as columns in CSV bulk uploads and exports.

The custom parameter boundary in the Custom Revenue and Payout system shifted accordingly. Custom params beyond adv10 still cannot be used as macros in postbacks. See Parameters and Macros Supported by Everflow for the full reference.
