Compatibility and versions

Current candidate pair: Core 2.5.0-dev.3 and Pro 1.1.0-dev.15. Candidate versions come from the authoritative Leanmerce Release records; no stable release is implied.

Audited headers require WordPress 6.9+, PHP 7.4+, WooCommerce, and declare WooCommerce 10.9 minimum/11.0 or newer. The documented pair is Core 2.5.0-dev.3 and Pro 1.1.0-dev.15; Pro declares Core 2.5.0-dev.3 minimum.

Reported coverage includes PHP 8.1/8.4, HPOS, classic checkout and Cart/Checkout Blocks. State intended support separately from exact tested combinations in future release reports.

Fresh versus migrated installations

A fresh install creates no locations and has no legacy behavior enabled. Migrated v1.9 installations preserve legacy options/assignments and can expose Legacy Compatibility controls. Run the bundled read-only legacy preflight before replacing v1.9, keep its checksums with the backup, and review fallback-dependent products before disabling compatibility.
