Which PrestaShop versions does MPR Compare support?

The module declares compatibility from PrestaShop 1.7.0.0 up to the 9.x line, and its code carries two separate sets of hooks. On 1.7, 8 and 9 it uses actionFrontControllerSetMedia, displayAfterProductAddCartBtn, displayNav2 and displayBeforeBodyClosingTag, while legacy 1.6 themes fall back to displayHeader, displayProductButtons, displayNav and displayFooter with a dedicated 1.6 comparison template.

Prices on the comparison page are formatted through a version-aware wrapper, so the feature keeps working on PrestaShop 9, where the old price-display helper was removed.
