PrestaShop 8, the first major version since the original release of PrestaShop 1.7.0 back in 2016, is an important milestone for the project.
A significant cleanup has been performed in the codebase, with several internal components updated, modified or removed. PrestaShop 8 is also the project’s first company-neutral release, meaning that it no longer includes commercial products and services built-in.
In addition to over 170 bug fixes (including 4 new fixes since the release candidate), PrestaShop 8 brings compatibility with PHP 8.1, updated libraries including Symfony 4.4, an improved experimental product page, a new security page, and many other features for developers and merchants alike.

PrestaShop 8 is a major version in the SemVer sense of the word. This means that while it brings several new features and a number of important changes, most themes from PrestaShop 1.7 should remain compatible with PrestaShop 8. Some modules, however, might need to be updated to be compatible with this new version.
