Confirmed compatibility: tested up to WordPress 7.0.1 and WooCommerce 10.9.4.
3.7.8
Free version: removed the 2-category limit and the eligible-categories picker on the Settings tab.
Show the per-product payment gateway selector on every product, regardless of category.
Per-product gateway selection now takes priority over category, tag, and default fallback settings; when a product has no selection, the category/tag rules and default fallback apply.
3.7.7
Show free-tier category picker on the Settings tab (was built but never rendered).
Enable Save on the free version so categories and default payment can be stored.
Merge settings on save so premium saves do not wipe unrelated keys.
3.7.6
Update Freemius WordPress SDK to 2.13.2.
3.7.5
Remove duplicate legacy category/tag save handlers (admin_post handlers are used).
Fix Freemius helper functions to use dfm_pgppfw_fs() instead of my_fs().
Enforce free-tier 2-category limit server-side on settings save.
Wire is_product_eligible() to respect selected categories in the free version.
