AlsoPurchasedTurbo v1.2.0

New in v1.2.0:

• "Optimize table (reclaim disk space)" maintenance action. InnoDB keeps
  deleted rows' space inside the tablespace after pruning; this rebuilds
  the table and shrinks the file on disk, reporting resulting size and
  space reclaimed. Help text shows current size and internally
  reclaimable space.
• After a prune that removes 100k+ rows, a message points at the
  optimize action.
• "Last prune" and "Last optimize" status rows in the Tools page Engine
  status panel (when they ran, before/after counts, size on disk, space
  reclaimed).
• "Table size on disk" status row, flagging internally reclaimable space
  when present.
• Admin page CSS: px pinning for code/help text per ZC 2.x admin
  convention.
• Installer: APT_OPTIMIZE_STATS status-tracking configuration key.

Upgrade from v1.1.0 via Plugin Manager (new configuration key seeded).
v1.1.0 directory replaced by v1.2.0 (v1.1.0 remains available via its
release tag).

AlsoPurchasedTurbo v1.1.0

Pair pruning release.

Bounds the pair table on large stores — motivated by a 167k-order production store whose unpruned table reached 40M rows / 4.5 GB:

• New APT_MAX_PAIRS_PER_PRODUCT setting (default 50, 0 = unlimited): the storefront only ever displays a handful of recommendations, so keeping every historical pair wastes space and slows the per-product read
• New "Prune pair table" tool — chunked, auto-continuing, safe to run any time; keeps each product's strongest pairs per the configured ranking, with no visible change to the storefront
• Pruning runs automatically after seeding completes
• "Last prune" shown in the Tools status panel (when it ran, before/after row counts)
• Installer: shared idempotent install/upgrade building blocks per Zen Cart encapsulated-plugin guidance
• Manifest: plugin library id 2443; Zen Cart v2.1.0 / v2.2.2

Requires Zen Cart 2.1.0+ (tested on 2.2.2). New installs: attached zip via Plugin Manager, then seed from Tools > Also Purchased Turbo. Upgrading from v1.0.0: use Plugin Manager's Upgrade button (a new configuration setting is seeded — file-swap alone isn't enough), then optionally click "Prune pair table" to trim an already-seeded table.

AlsoPurchasedTurbo v1.0.0

Initial release.

Replaces Zen Cart's stock also-purchased engine with a precomputed product-pair table:

• Indexed pair-table lookup instead of the orders_products self-join on every product page (benchmark: 96.4 ms → 0.37 ms on the store's most popular product)
• Recommendations ranked by purchase affinity (Recency and Random modes available)
• Checkout observer keeps the table current in real time; admin-driven chunked seeding from order history
• No core-file or template changes; customized template modules are detected and never overwritten (takeover or integration paths in the readme)
• Admin: Configuration > Also Purchased Turbo and Tools > Also Purchased Turbo (status, seeding, maintenance, shim health, debug log)

Requires Zen Cart 2.2.2+. Install the attached zip via Plugin Manager, then run the seed from Tools > Also Purchased Turbo.
