Divi Nitro Changelog

/* CHANGELOG */

VERSION 5.0.1 – 10/08/26

  • FIX – Removed temporary Divi CSS cache debug logging that could fill debug.log when WP_DEBUG is on.

VERSION 5.0.0 – 07/08/26

  • NEW – Defer Video for Divi 5 in the Visual Builder, with conversion from the Divi 4 module, privacy-enhanced YouTube/Vimeo embeds, aspect ratio options, keyboard-friendly play controls, and ACF OEmbed/image selection for dynamic videos. Loads the matching Divi 4 or Divi 5 assets when the module is on the page.
  • NEW – Page Cache: anonymous HTML caching (Smart or Full page mode) with Theme Builder–aware clearing, dynamic regions (mini cart stays live), adaptive TTL, warming, analytics, optional Redis/Cloudflare/Nginx purge, a Cached pages list, and admin-bar clear for this page or all. Divi Engine–aware: Ajax Filter URLs cache separately, Protect unlock cookies skip cache, Membership account paths are excluded, Mega Menu Ajax Loaded URLs bypass cache, Form Builder edit/payment URLs skip cache, plus cookie skip settings and an optional “Do not cache filtered Ajax Filter URLs” toggle.
  • NEW – Debug tools: temporarily disable all Nitro performance features without deactivating the plugin, plus optional Page Cache debug logging with a log viewer you can copy or export.
  • NEW – Lazy Rendering: delay painting far-below-the-fold Divi sections so long pages feel faster (opt-in; also in Aggressive preset), and remember below-the-fold sections in the page cache for first paint.
  • NEW – Performance presets: Safe, Balanced, and Aggressive one-click profiles (Balanced/Aggressive turn on anonymous Page Cache unless another cache plugin is active).
  • NEW – Smart Image Loading (replaces Defer Images): smart lazy with LCP protection, classic onload defer, or off — plus per-module Load immediately / Lazy load on Image, Fullwidth Image, Gallery, and Blurb.
  • NEW – Smart Minify suggestions and Frontend Asset Helper (admin bar): review scripts and styles, apply safe queues, Clear Minify Cache, and a suggestions card in Minify settings. Hides admin-only items, keeps Divi and protected items out of public queues, and pre-checks items already queued.
  • NEW – Fonts & Resource Hints: font-display swap for Google Fonts, preload critical fonts, and preconnect to Google Fonts, YouTube, Vimeo, or custom hosts.
  • NEW – Performance Insights: setup score (0–100), homepage Page score checks, browser load estimate, and Divi Engine plugin detection for Page Cache protections, with Setup suggestions and Page scan in tabs.
  • NEW – Speculative Loading (WordPress 6.8+): prefetch or prerender the next page with safe cart/checkout/account exclusions.
  • NEW – Delay JavaScript until interaction (or a short timeout), with jQuery and Divi Engine form/filter scripts kept immediate by default. Divi Engine scripts stay out of Minify and Delay JavaScript by default.
  • NEW – Database Cleanup: remove revisions, auto-drafts, trash, spam, and expired transients, optimize tables, optional weekly runs, live counts, and a progress modal while cleaning.
  • NEW – Clear Divi’s CSS cache when Nitro settings or minify cache update, and from the Divi Nitro admin bar.
  • NEW – Divi 5 page settings: remove specific scripts and styles from a page in the Visual Builder (shared with the WordPress meta box).
  • MOD – Divi Engine admin menu shows a single Nitro Settings hub (Minify under Scripts & CSS) with clearer navigation, renamed sections (WordPress Cleanup, Browser Caching), grouped sidebar intros, and your existing options kept.
  • MOD – Page Cache settings show store backend, Redis status, object-cache detection, Cloudflare last-purge status, TTL quick badges, and clearer hit-rate help.
  • MOD – Section background images load near the viewport with early-load distance; first (LCP) background stays visible; Asynchronous CSS does not override Divi Critical CSS.
  • MOD – Licence checks no longer repeat the same remote request twice in one admin visit; plugin details cache update info for a few hours and still refresh on Check for updates.
  • FIX – License activate and deactivate on the Divi Engine settings page work reliably, and if the server rejects deactivation (for example with an expired order), your local license key is still cleared.
  • FIX – Plugin updates list and install reliably on the Plugins screen, without false “update available” notices when you already have the latest (or a newer development) build.
  • FIX – Script and style optimization options in plugin settings no longer break the admin screen when the site uses a current jQuery version (for example with jQuery Migrate disabled).
  • FIX – Page Cache: when WP_CACHE is false in wp-config.php (common on hosts/staging), Nitro now sets it to true so early cache serving can run — and shows a clear admin and settings warning if it still cannot.
  • FIX – Smart Page Cache: Theme Builder body layouts are no longer shared across URLs (products/posts using the same template were showing each other’s content). Header and footer can still be shared; purge Page Cache after updating.
  • FIX – Legacy settings import and reset now check permissions and security nonces, and sanitize request data.

VERSION 4.0.1 – 14/05/26

  • NEW ADDITION: Defer Video Module: ACF OEmbed and image selection so you can use dynamic video selection with ACF
  • MOD – Licence checks on admin load no longer repeat the same remote request twice in one visit when the daily review runs at the same time.
  • MOD – Plugin details on the Plugins screen cache update information for a few hours and still refresh when you use Check for updates.
  • FIX – License Deactivation: Fixed issue where customers with expired orders could not remove their license key locally. When the server rejects deactivation, the local license key is now still cleared.
  • FIX – Plugin update checks now register correctly so new versions show up under Plugins when available.
  • FIX – WordPress now lists and installs plugin updates reliably when a new release is available on your licence.
  • FIX – Script and style optimization options in the plugin settings no longer break the admin screen when the site uses a current jQuery version (for example with jQuery Migrate disabled).
