Auctions & Bidding changelog

All notable changes to Auctions & Bidding (kv_auction_bidding) are documented here. The format follows Keep a Changelog and the project uses Semantic Versioning.

  • Timed auctions per product: start and end in the store time zone, starting price, fixed or tiered bid increments, hidden reserve price, Buy Now price, one item per auction.
  • Manual and maximum (proxy) bids with second-price logic; bids placed under a database lock (one leader, one winner).
  • Anti-sniping: late bids extend the auction, with a maximum number of extensions.
  • Live auction panel on the product page and in quick view, list badges, full page cache support.
  • Registered bidders with stored acceptance of the bidder terms and optional manual approval.
  • Idempotent closer (cron, page view, admin fallback); winner payment at the winning bid enforced in the cart; payment deadline, second-chance offers and relisting.
  • My auctions page; e-mails for outbid, won, lost, canceled, payment time passed, second chance, auction ended and winner did not pay.
  • Admin auctions list with statistics and CSV export, auction page with bid log, bid and auction cancellation, bidders page.
  • Multi-Vendor: vendors manage auctions for their own products.
  • Domain-bound license check and self-healing upgrades.
