Changelog

4.75 (17th December 2021)

• Upgraded the update checker - checked the two errors that I fixed earlier are fixed in the update.
• Altered the update checker to use Bitbucket instead of my own server

4.74 (17th December 2021)

• Hardened plugin update checker - an error was occurring if the wpintense json file was not available

4.73 (15th December 2021)

• Added 3 new indexes for the new way WP All Import performs image lookups

4.72 (10th November 2021)

• Merged old items into core

4.71 (4th November 2021)

• Added scalability fix for order admin issue caused by the Order Delivery Date plugin

4.70 (2nd November 2021)

• Added index to wp_options on name - found in perf analysis that this is actually a very frequent SQL pattern and when > 2000 options exist it starts to get noticable
• Added index to wp_comments to assist with admin area where comment counts are counted by comment type
• Added count users cache for wp-admin order admin speed boost - it's only used to display a dropdown in the list orders screen (and possibly other screens)
• Refactored how indexes are created - paves the way for selective indexing in future

4.69 (22nd October 2021)

• Hardened code to avoid fatal warning at end of overnight cron job if WooCommerce not installed - checks for existence of wc_recount_all_terms - was not affecting anything other than creating an error in debug.log

4.68 (9th September 2021)

• Added optimisation for WCFM Multivendor marketplace - the query they have to generate the STORE filter is not scalable, made scalable with this update
• Added 2 indexes to support improved query for WCLOVERS WCFM Multivendor Marketplace plugin - wp_usermeta.wpi_wclovers_wcfm_marketplace_usermeta and wp_users.wpi_wclovers_wcfm_marketplace_users - even just 6000 entries in wp_usermeta (10 users) is enough to add 0.5 seconds to page load, but with this index + query alteration the same query is 0.003 seconds

4.67 (3rd September 2021)

• Added settings control over the option to remove OR post_status = 'private' to front-end queries. Doing this can speed up WP_Query in some cases. Using this option will stop private items displaying on your front-end.

4.66 (31st August 2021)

• Altered code that removes check for private posts to never run on wp-admin pages

4.65 (30th July 2021)

• Improved Defer Term Count code to speed up imports

4.62 (30th September 2020)

4.60 Beta (1st May 2020)

4.59 Beta (16th April 2020)

• Changed mechanism for the 'WHERE NOT EXISTS' option to make it work with all taxonomies and multiple taxonomies (previously was disabled and when enabled it only handled 1 taxonomy) - this optimisation helps in many cases but not all - you'll need to test it to check with your data config

4.58 (31st March 2020)

• Added new index on wp_posts on just the guid column. Some themes grab posts directly using SQL against wp_posts and just use the guid. Typically this is when they're grabbing images. They shouldn't do it that way but some do.

4.57 (27th August 2019)

• Fixed bug related to 'removing woocommerce ajax variations count' which improves performance of pages with many variations
• • bug was related to items which didn't have all variations created. Fix was to return at least 1 of the variations which seems to fix the Woo JS code so that it will correctly use Ajax to fetch prices.

• WHERE EXISTS experimental option now fixed - if all 3 wp_query options set, dogs category on foundthru is 0.0009s

4.49 (1st April 2019)

• Swapped out use of dbDelta to use generic CREATE statement instead since it seems there is a bug inside WordPress core - https://wordpress.stackexchange.com/questions/141971/why-does-dbdelta-not-catch-mysqlerrors/141984
