Functional fixes and enhancements

We address the following functional fixes and enhancements in this release.

Catalog

  • Magento no longer locks the category_product_entity table. Unlocking this table reduces the potential of lock-related timeouts that can occur when indexing and checkout operations run in parallel. Previously, Magento locked the category_product_entity table.
  • The storefront now displays images that Magento resizes during product save operations, rather than resizing the product on the storefront. Previously, the image path contained store_id, and during save operations, Magento resized images for images the default store only.

Users have encountered problems displaying images after upgrading their software to Magento 2.1.6. These problems range from incomplete loading to the total inability to load images. Consequently, if you saved a product and didn’t open it on the storefront before upgrading to 2.1.6, you’ll need to apply a workaround.

Workaround: To correct problems with image loading, choose one of these two workarounds:

  • Run php bin/magento catalog:images:resize

or

  • Save (or resave) the product with the associated image in the Admin panel.
  • The \Magento\CatalogInventory\Model\Stock\Status\getStockId() method now returns the correct values.
  • The \Magento\CatalogInventory\Model\Stock\Status\getStockId() method now returns the correct values.

Configurable products

  • The check that Magento runs to confirm a configurable product’s readiness for sale is now faster. (The isSalable method checks that a configurable productcan be sold (that is, is in a saleable state)).
  • Magento no longer calculates configurable product special prices on the category page. Previously, Magento calculated special prices on the category page, but did not display them.

Indexers

  • Magento now runs a selective partial re-indexing operation after import if you enabled Update on Schedule. Previously, Magento ran a full reindex no matter which index mode was set.

Import

  • Magento now displays imported product images in this order: first, the base image, then the additional images in the order in which they were listed in the CSV file. Previously, Magento displayed images in this unexpected order: first, an additional image, then the base image, and finally, all remaining additional images.

Miscellaneous

  • Magento now caches attribute options for the layered navigation feature. This reduces the number of queries to the database, and consequently improves performance.
  • Magento no longer performs unnecessary file check operations (for example, file_existsis_file), which improves the performance of the category and product pages.
  • Magento now caches image metadata, which avoids the time-consuming need to read images for metadata loading.
  • Magento now shows a significant decrease in Redis traffic after upgrading 2.1.2 to 2.1.4.

Swatches

  • Magento no longer creates redundant objects when initializing a configurable product on the Category page.
  • You can now disable swatches for both the Catalog page and search results (quick or advanced). To disable swatches from these requests, disable Stores > Configuration > Catalog > Storefront > Show Swatches in Product List.
  • The logic that Magento uses to validate swatch attributes has been optimized.
  • Magento now caches swatch data in the block cache, which improves the responsiveness of the configurable product pages.
