| 41 | 45 | |
| 42 | -Your pages are saved as static HTML files and served instantly to visitors — before WordPress even loads. The cache rebuilds itself automatically whenever you publish a post, switch themes, or update a plugin. You never have to think about it. | |
| 46 | +**AI Assistants and the WordPress MCP Server** | |

| 44 | -* Static-file rewrite path (bypasses PHP entirely — 5–15ms TTFB) | |
| 45 | -* Auto-purge on publish, update, comment, theme change | |
| 48 | +xSpeed Cache ships a WordPress MCP server, so a Claude WordPress MCP connection, or any other MCP client, can inspect and tune your site through the same tools the dashboard uses. Every action is bounded by what you allow when you connect, which is what separates a real WordPress MCP plugin from a chatbot bolted onto a settings page. | |
| 49 | + | |
| 50 | +* MCP server appears on the Overview as a capability card, so an AI connection can be set up without hunting for a panel | |
| 51 | +* OAuth discovery, with dynamic client registration bounded by stored-client limits, redirect URI limits, name and URI length limits and per-IP rate limiting | |
| 52 | +* Read-only MCP connections can read status through every per-command tool, while write actions stay refused | |
| 53 | +* Credentials cannot be written by an AI assistant unless you explicitly grant that permission when connecting | |
| 54 | +* WP-CLI parity: `wp xspeed purge`, `wp xspeed preloader status`, `wp xspeed score run`, `wp xspeed optimize` and `wp xspeed settings list|get|update` | |
| 55 | +* The `optimize_site` tool measures the site, applies recommended settings one at a time, re-checks the page after each change and reverts anything that breaks it | |

| 175 | 205 | |
| 176 | -= Will this break my site? = | |
| 206 | += Does it support multisite? = | |
| 177 | 207 | |
| 178 | -Very unlikely. xSpeed includes safety checks for every optimization: minification falls back to the original if anything looks off, and the cache bypasses logged-in users, admin pages, AJAX, and REST requests automatically. If something ever looks wrong, you can toggle any feature off individually. | |
| 208 | +Yes. Each site in the network gets its own cache and settings. | |
| 179 | 209 | |
| 180 | -= Does it work with WooCommerce? = | |
| 210 | += Is this a WordPress MCP adapter? = | |
| 181 | 211 | |
| 182 | -Yes. Add `/cart`, `/checkout`, and `/my-account` to the Excluded URLs list and xSpeed will skip caching those pages. Logged-in customers are never served cached pages regardless. | |
| 212 | +Not exactly. A WordPress MCP adapter usually exposes core WordPress data. The xSpeed Cache MCP server exposes the performance tools this plugin owns, such as cache purging, preloader status, score runs and settings reads and writes, so an assistant works on speed rather than on content. | |

| 216 | +Yes. A WordPress MCP Claude connection uses OAuth discovery, and the MCP server appears on the Overview as a capability card so you can set it up without hunting for a panel. Read-only connections stay read-only. | |
| 187 | 217 | |
| 188 | -= Does it support WordPress Multisite? = | |
| 218 | += Is xSpeed Cache the best free WordPress cache plugin? = | |
| 189 | 219 | |
| 190 | -Yes. Each site in the network has its own independent cache and settings. | |
| 220 | +That is for you to judge, but here is the honest basis for comparison. The static-file rewrite path serves cached pages before PHP loads, across Apache, nginx and LiteSpeed, which most free plugins do not do. Object caching, CDN support and database cleanup are included rather than reserved for a paid tier. | |
| 191 | 221 | |
| 192 | -= Will it conflict with LiteSpeed Cache? = | |
| 222 | += Can it replace my separate WordPress page speed plugin and CDN plugin? = | |

| 194 | -No. xSpeed detects LiteSpeed's server-level caching module and steps back automatically to avoid double-caching. Otherwise, only run one page-cache plugin at a time. | |
| 224 | +In most cases yes. Page caching, minification, GZIP, lazy loading, font optimization, browser caching, object caching, WordPress CDN support and database cleanup are all in one plugin, so you are not stacking a WordPress page speed plugin on top of a cache plugin on top of a database tool. | |

| 228 | +It targets the parts a plugin can influence. The static cache improves server response time, the LCP preload picks the largest image on the page rather than the first, lazy loading defers offscreen media, and the automatic Cumulative Layout Shift fix stops the layout jumping. Page weight and DOM size are reported to you, since only a person can fix those. | |

| 230 | += What is the MCP server for? = | |
| 231 | + | |
| 232 | +The MCP server lets an AI assistant connect to your site and use the same tools the dashboard uses, such as purging cache, checking preloader status, running a score and reading or updating settings. Read-only connections stay read-only, and credentials cannot be written unless you explicitly grant that permission when connecting. | |
| 233 | + | |
| 234 | += Will this break my site? = | |
| 235 | + | |
| 236 | +Very unlikely. xSpeed Cache includes safety checks for every optimization: minification falls back to the original if anything looks off, and the cache bypasses logged-in users, admin pages, AJAX and REST requests automatically. If something ever looks wrong, you can toggle any feature off individually. | |
| 237 | + | |
| 200 | 238 | = How do I clear the cache? = |

| 280 | -**MCP support for AI assistants, LCP optimization, and admin experience improvements.** | |
| 312 | +**Purging is now a contract other caches can join: clearing xSpeed's page cache also invalidates LiteSpeed Cache and the host's nginx FastCGI cache, and every purge is scoped to exactly the site and pages it was asked for — including on multisite.** | |
| 281 | 313 | |
| 282 | -AI / MCP: | |
| 283 | -- New: MCP server support for Claude and other MCP-compatible AI assistants. | |
| 284 | -- New: Secure OAuth 2.1 connection for remote AI assistants. | |
| 285 | -- New: MCP dashboard with available tools and permissions. | |
| 314 | +Caching: | |
| 315 | +- New: A purge-event contract lets other caching layers invalidate together with xSpeed, so a purge clears every cache that matters in one action. | |
| 316 | +- New: Purge All is forwarded to LiteSpeed Cache and the host's nginx FastCGI cache when they are present. | |
| 317 | +- Fixed: One post change triggers exactly one invalidation, deleting a media file purges again, and a purge still finds its post when the hook hands over none. | |
| 318 | +- Fixed: Purges are scoped per site on multisite — a purge no longer sends another site's URLs to this site's server cache, a default port is not treated as a different site, and full purges stay on the current site. | |
| 319 | +- Fixed: A purge listener that throws no longer aborts the purge, a query string of "0" is still treated as a query, and a partial purge reports itself as partial instead of claiming success. | |
| 286 | 320 | |
| 287 | -Performance: | |
| 288 | -- New: Resource Hints with LCP image preload and font preconnect. | |
| 289 | -- Fixed: Improved LCP image loading by preventing lazy loading on the hero image. | |
| 321 | +Optimization: | |
| 322 | +- Fixed: Delaying JavaScript no longer breaks inline scripts bound to a delayed handle, and replayed external scripts keep their original load order. | |
| 290 | 323 | |
| 291 | -Dashboard & Admin UX: | |
| 292 | -- New: Settings shortcut from the WordPress Plugins page. | |
| 293 | -- Improved: Updated admin menu organization and dashboard navigation. | |
| 294 | -- Improved: Better Pro license messaging and settings search experience. | |
| 295 | -- Fixed: Checkbox rendering in both light and dark mode. | |
| 324 | += [1.3.1] – 2026-09-14 = | |
| 296 | 325 | |
| 297 | -Reliability: | |
| 298 | -- Fixed: Improved cache permission handling on non-NGINX servers. | |
| 326 | +**Purge all now says what it actually cleared, on the button and in the toast, instead of claiming success when a store refused. Pro features are marked with one lock everywhere rather than amber squares and crowns, which also lifts the dimmed labels back to readable contrast. The Cloudflare panel is staged by connection state, so setup comes before the actions that depend on it — and the auto-purge switch is visible while disconnected instead of hidden.** | |

| 300 | -= [1.0.7] – 2026-07-05 = | |
| 328 | +Dashboard & Admin UX: | |
| 329 | +- New: Purge all reports its outcome — Cleared, Already empty, Partly cleared or Purge failed — and the toast names the files and size cleared plus any other store, or the reason a store refused. | |
| 330 | +- Fixed: Pro features are marked with a single lock in the teal tint. Locked tabs are no longer dimmed to 70%, which had dropped their labels below readable contrast, and the amber squares, crowns and sparkles are gone from the tabs, badges and the sidebar tier slot. | |
| 331 | +- Fixed: Turning caching on no longer flashes "Another plugin owns the page cache on this site" while the toggle is in flight. A genuine foreign drop-in still shows the banner. | |
| 332 | +- Fixed: The Purge all button keeps its natural width at rest instead of reserving room for the outcome label. | |
| 301 | 333 | |
| 302 | -**Improved reliability, granular cache management, Redis compatibility, and asset optimization fixes.** | |
| 334 | +Cloudflare: | |
| 335 | +- New: The panel is staged by connection state — Connection, then Actions — so credentials and Verify come before the buttons that need them, and an action that cannot work is disabled with a hint rather than failing silently. | |
| 336 | +- Fixed: The auto-purge-on-purge switch is always visible, dimmed while disconnected, instead of being hidden until connected. Hiding it is how the edge-sync switch went unnoticed. | |
| 303 | 337 | |
| 304 | -Caching: | |
| 305 | -- New: Granular cache purge options for Page/Static, CSS/JS, Object Cache, and REST Cache. | |
| 306 | -- Fixed: Improved compatibility with previously installed caching plugins. | |
| 307 | -- Fixed: Purge All now properly clears optimized assets, object cache, and triggers CDN/edge purges. | |
| 338 | +Documentation: | |
| 339 | +- Fixed: The full changelog moved to changelog.txt, shipped with the plugin and linked from the plugin page. wordpress.org truncates a changelog over 5,000 words on import, so the history past the cut had been dropped. | |
| 308 | 340 | |
| 309 | -Object Cache: | |
| 310 | -- Fixed: Redis 6+ ACL compatibility for managed hosting environments. | |
| 311 | -- Improved: Object cache write verification for better reliability. | |
| 312 | -- Improved: Site-specific object cache flushing for shared Redis environments. | |

| 317 | -- Fixed: Combined CSS files are regenerated correctly after cache purge. | |
| 318 | -- Fixed: Relative asset paths are preserved in optimized CSS. | |
| 343 | +**A single page can now be purged straight from the admin bar, the post list or the editor, and known third-party scripts — analytics, chat widgets, tracking pixels — are delayed automatically without asking you to list them.

| 346 | +- New: Purge a single page from the admin bar, the post list's row actions, or the editor — and the purge confirms what it actually removed instead of assuming. | |
| 347 | +- New: `wp xspeed purge` clears every cache in one call, and a purge is scoped to exactly what the caller asked for. | |
| 348 | +- New: Publishing or updating a post also purges the pages that list it, not just the post itself. | |
| 349 | +- New: An abandoned page-cache drop-in left by another plugin can be taken over with one consenting click, and a leftover husk of a drop-in no longer blocks caching forever. | |
| 350 | +- Fixed: A migration handover now completes instead of stopping halfway, from the dashboard and the CLI alike. | |
| 351 | +- Fixed: xSpeed no longer mistakes itself for a competing cache plugin. | |
| 324 | 352 | |
| 325 | -Migration: | |
| 326 | -- Fixed: Mobile cache migration compatibility for NGINX static cache. | |
| 353 | +Optimization: | |
| 354 | +- New: Known third-party scripts are delayed until interaction automatically, including the inline install snippets vendors ask you to paste into the header. | |
| 355 | +- New: Font stylesheets are deferred out of the render path, and a Google Fonts request that blocks rendering is rewritten to swap. | |
| 356 | +- New: A manual preload list covers the images no detector can see. | |
| 357 | +- Fixed: The LCP preload no longer picks a brand logo over the page's real hero image. | |
| 358 | +- Fixed: Deferring no longer breaks inline scripts that depend on another handle, combining no longer swallows scripts that delaying protects, and handle exclusions are honoured in the delay pass. | |
| 359 | +- Fixed: Valid minified JavaScript is no longer rejected, asset URLs are matched across schemes, an uploads folder at the domain root is recognised, and `?ver` is kept on files plugins rewrite in place. | |
| 360 | +- Fixed: Lazy loading reads an image's size from whichever attribute holds its URL, and no longer mistakes a real image for a placeholder because of a word inside its filename. | |

| 345 | -- Fixed: Image URL validation for media fields. | |
| 363 | +- New: Any module setting can be pinned from wp-config.php with a constant. The dashboard shows a pinned field as read-only and names the constant that holds it. | |
| 364 | +- New: An admin can take a pinned setting back — the override displaces the host's constant and only that. | |

| 346 | 366 | |
| 347 | -White Label: | |
| 348 | -- Fixed: Footer credit and Help & Support link controls. | |
| 349 | -- Fixed: Fallback to the default logo when a custom brand logo is unavailable. | |
| 367 | +Object Cache: | |
| 368 | +- New: Redis credentials and Memcached servers are read from wp-config.php, and `WP_REDIS_PREFIX` is honoured as a key salt. | |
| 369 | +- Fixed: Cache keys are always namespaced per site, so two sites sharing a Redis or Memcached database can no longer read or purge each other's entries. | |
| 370 | +- Fixed: The dashboard panel gained every fix that had only reached the CLI, owns only what the plugin itself wrote, and no longer presents another plugin's object cache as xSpeed's. | |
| 350 | 371 | |
| 351 | -Migration: | |
| 352 | -- New: One-Click Profiles and Save & Share with an improved import experience. | |
| 353 | -- Fixed: Import now counts and migrates only enabled source settings. | |
| 354 | - | |
| 355 | 372 | Reliability: |
| 356 | -- Fixed: Improved REST API error handling to prevent broken JSON responses. | |
| 373 | +- Fixed: Translations now load for both PHP and the dashboard, and the settings screens are translatable. | |
| 374 | +- Fixed: nginx sends one Cache-Control header per location instead of two, and the de-duplicated header no longer caches 404 responses. | |
| 375 | +- Fixed: An audit contributor that throws no longer takes the whole audit down with it, and add-ons can report findings of their own. | |
| 357 | 376 | |
| 358 | -Admin UX: | |
| 359 | -- New: Opt-in usage analytics (WP Insights). | |

| 361 | -- Improved: Pro upgrade links now point directly to the pricing page. | |
| 377 | +AI tools: | |

| 373 | - | |
| 374 | -LiteSpeed: | |
| 375 | -- Fixed: On LiteSpeed/OpenLiteSpeed, xSpeed now tells LSCache to stand down (X-LiteSpeed-Cache-Control: no-cache) and owns the cache itself, so the X-XSpeed-Cache header is emitted, hits are counted, and the dashboard no longer falsely reports a PHP fallback. | |
| 376 | -- Fixed: LiteSpeed cache hits route through the drop-in (which both tags and counts them) since OpenLiteSpeed's .htaccess can't tag or log a static hit — giving consistent ~1ms hits and an accurate hit ratio. | |
| 377 | - | |
| 378 | -Cache hit counting & stats: | |
| 379 | -- Fixed: Hit/miss counters moved off transients onto a persistent option, so they no longer evaporate when a non-persistent object cache (e.g. an unreachable Redis) is active — the hit ratio was getting stuck at a fake 0%/100%. | |
| 380 | -- Fixed: Cache MISSes are now recorded inline so the hit-ratio stat reflects reality instead of being pinned at 100%. | |
| 381 | -- Fixed: PHP-served cache HITs are counted correctly and the drop-in device-bucket desync is resolved. | |
| 382 | -- Fixed: Homepage now caches via the static rewrite (the rule used a pattern that required a non-empty path, so `/` fell through to PHP while inner pages were rewritten). | |
| 383 | - | |
| 384 | -Nginx: | |
| 385 | -- Fixed: A nginx access_log directive in the generated snippet could take down the whole server when its log file was missing; the path is now resolved lazily so a deleted hits.log can't fail `nginx -t`. | |
| 386 | -- Fixed: The dashboard's nginx server-block snippet now updates optimistically when you toggle cache, instead of showing the pre-toggle state, and the wizard's Done step shows the post-apply block. | |
| 387 | - | |
| 388 | -Admin UX: | |
| 389 | -- New: Collapsible sidebar groups for cleaner navigation. | |
| 390 | -- Improved: Renamed the "Cache" module label to "Page Cache" for clarity. | |
| 391 | -- Improved: Sidebar group icons and chevrons brighten correctly on hover (white in dark mode). | |
| 392 | - | |
| 393 | -Module fixes: | |
| 394 | -- Fixed: Lazy Load — four correctness bugs resolved. | |
| 395 | -- Fixed: Heartbeat — editor-context detection, CLI set support, and honest frontend copy. | |
| 396 | -- Fixed: Database cleaner — expired-transient cleanup gaps and a count mismatch. | |
| 397 | -- Fixed: Google Fonts — no longer double-appends `display=swap` on entity-encoded hrefs. | |
| 398 | -- Fixed: Settings now strictly validate boolean fields instead of casting, preventing bad values from silently becoming `true`/`false`. | |
| 399 | -- Fixed: Object Cache — core option groups marked non-persistent so the drop-in can always be deactivated; degraded backends detected honestly. | |

| 408 | -- Improved: Dashboard now reports a degraded object cache honestly when the drop-in can't reach its backend, instead of implying caching is healthy. | |
| 409 | - | |
| 410 | -Admin UX: | |
| 411 | -- New: WP admin submenu now mirrors the in-dashboard navigation, so the menu and dashboard tabs stay in sync. | |
| 412 | -- Improved: Settings changes apply live across dashboard navigation — no full page reload needed. | |
| 413 | -- Improved: Menu icon now recolors to the active accent state correctly. | |
| 414 | -- Improved: Success notifications are anchored to a single consistent position (bottom-center). | |
| 415 | -- Fixed: Long panel titles no longer push the subtitle off-screen. | |
| 416 | -- Fixed: Number-input spinners render consistently across browsers (Firefox no longer clips the value). | |
| 417 | - | |
| 418 | -Cache exclusions: | |
| 419 | -- New: Exclusion lists now ship pre-populated with LiteSpeed / WP Rocket-parity defaults (16 URLs, 20 cookies, 28 query params), so a fresh install caches correctly out of the box. | |
| 420 | -- New: Exclusion rules now support regex via a `~` prefix (e.g. `~utm_[a-zA-Z0-9_-]+`), alongside glob and substring, with ReDoS guards. | |
| 421 | - | |
| 422 | -Bug fixes: | |
| 423 | -- Fixed: Browser Cache no longer emits an "Array to string conversion" warning on multi-valued Cache-Control headers (also clears a false "nginx config required" notice). | |
| 424 | - | |
| 425 | -License: | |
| 426 | -- Fixed: Activating a Pro license now unlocks the Pro panels immediately — no full page reload needed. | |

| 430 | -**Topology-aware UX, nginx HIT counting, admin polish.** | |
| 431 | - | |
| 432 | -Cache topology & UX: | |
| 433 | -- New: Topology-aware rewrite banner — the dashboard now detects containerized hosts (xclude, Kinsta, RunCloud Atomic, etc.) where the `$document_root` assumption doesn't hold, and tells the user exactly what to expect on their stack instead of silently failing. | |
| 434 | -- New: Unified nginx server-block snippet — one consolidated, copy-pasteable snippet (collapsible in the UI) replaces the previous fragmented sections. | |
| 435 | -- New: Nginx-served HITs are now counted — a dedicated access_log captures cache hits served directly by nginx (no PHP), so the dashboard "HITs in last 24h" stat is accurate on nginx setups. | |
| 436 | -- New: `X-XSpeed-Cache` response header — cache hits are now visible in the response headers, with a distinct value per serve layer (`HIT (nginx)` for the fast static path, `HIT (php)` for the drop-in fallback) so you can confirm a page was cached and tell exactly which layer served it. | |
| 437 | -- Improved: Browser Cache notice is topology-aware and renders its snippet in a proper code block. | |
| 438 | - | |
| 439 | -Admin UX: | |
| 440 | -- New: Third-party admin notices are suppressed on xSpeed admin screens (`page=xspeed*` only) — other plugins' "rate us" / promo notices no longer crowd the xSpeed dashboard. | |
| 441 | -- New: Aligned sticky title-bar across the sidebar and content panels for a cleaner scroll experience. | |
| 442 | -- Improved: Browser Cache + GZIP notices probe-gate themselves — once the underlying issue is resolved, the notice dismisses on its own instead of lingering. | |
| 443 | - | |
| 444 | -Benchmark: | |
| 445 | -- Fixed: "Without cache" leg of the dashboard speed test now appends a cache-buster query string. Previously it was hitting the cache and reporting an artificially-fast baseline, making the speedup number look small. | |
| 446 | - | |
| 447 | -= [1.0.2] – 2026-06-02 = | |

| 449 | -**Static-rewrite cache, Site Health & Fonts.** | |
| 450 | - | |
| 451 | -Static-rewrite cache + Site Health: | |
| 452 | -- New: Static-file rewrite path — cached HTML is served directly by Apache / nginx / LiteSpeed, bypassing PHP entirely on cache hits (5-15ms TTFB vs ~85ms via the PHP drop-in). | |
| 453 | -- New: .htaccess static-cache block — installed automatically on cache enable, removed cleanly on disable. Block precedes WordPress's own rules so static files match first. | |
| 454 | -- New: nginx config snippet — copy-pasteable server { } block surfaced in the dashboard when nginx is detected (PHP can't write nginx config). Avoids the "if is evil" pitfall via a named-location fallback. | |
| 455 | -- New: LiteSpeed LSCache coexistence — xSpeed detects LSCache's server-level module and steps back instead of double-caching. | |
| 456 | -- New: Active rewrite probe — Health module pings the cache directory and confirms the rewrite is actually serving static bytes (not just present in .htaccess). | |
| 457 | -- New: WordPress Site Health integration — Tools → Site Health now lists an xSpeed check covering static-rewrite status + nginx config requirements. | |
| 458 | -- New: Persistent banner — Cache panel warns the admin when caching is on but the static-rewrite block isn't engaged (slow fallback path). | |
| 459 | -- New: Copy-to-clipboard button on every config-snippet panel (nginx, GZIP, object-cache). | |
| 460 | - | |
| 461 | -Fonts: | |
| 462 | -- New: Fonts module — adds `font-display: swap` to enqueued web fonts so visible text doesn't wait on a slow Google Fonts response, and exposes a preload list for above-the-fold font files. | |
| 463 | -- New: FontsModule tests covering the swap rewrite + preload `<link>` emission. | |
| 464 | - | |
| 465 | -Improvements & fixes: | |
| 466 | -- Improved: Server-type detection is cached so CLI / cron contexts see the same server type as web requests. | |
| 467 | -- Improved: Drop-in (advanced-cache.php) and WP_CACHE constant are preserved across plugin upgrades; auto-heal hook tightened to admin_init to avoid REST/cron noise. | |
| 468 | -- Improved: Plugin Check pass — i18n textdomains, WP_Filesystem coverage, SQL preparation, sanitization, and plugin/readme headers all cleaned up for WordPress.org review. | |
| 469 | -- Fixed: nginx snippet rewritten to avoid the try_files trap that broke pretty permalinks. | |
| 470 | -- Fixed: Rewrite condition normalized for trailing-slash + non-trailing-slash URLs. | |
| 471 | -- Fixed: WP-Rocket-style canonical pattern — server-level conditional rewrite. | |
| 472 | -- Fixed: Minify tag-rewrite filters bail in non-frontend contexts (REST / admin / cron). | |
| 473 | -- Fixed: wp.org release zip now ships `vendor/` — resolves the 1.0.1 activation fatal. | |
| 474 | -- Improved: Release pipeline rebuilt — `.distignore`-driven dist build, CI verify step, version-named artifact on every run. | |
| 475 | -- Improved: Plugin version read from the PHP header — single source of truth. | |

| 479 | -**Foundation release — full feature set + Pro hooks.** | |
| 480 | - | |
| 481 | -Module architecture + LiteSpeed parity floor: | |
| 482 | -- New: Module architecture — every feature now ships as a self-contained Module (Cache, Health, Preloader, Heartbeat, Minify, GZIP, Lazy Load, Disable Bloat, Database, CDN, Cloudflare, Object Cache, Browser Cache). | |
| 483 | -- New: Health module — 24-hour hit/miss counter + activity log. | |
| 484 | -- New: Preloader module — sitemap-driven cache warmer with content-publish auto-warm. | |
| 485 | -- New: Cache exclusion intelligence — glob URL patterns, cookie patterns, User-Agent bypass, ignored query parameters. | |
| 486 | -- New: Per-device cache (mobile-separate). | |
| 487 | -- New: Per-post cache rules — don't-cache + custom expiry meta box. | |
| 488 | -- New: Minification — CSS / JS / HTML minify, combine, defer JS, delay JS, async CSS, remove ?ver= query strings. | |
| 489 | -- New: Lazy Load module — images / iframes / videos + auto CLS-fix. | |
| 490 | -- New: Disable Bloat module — 6 ergonomic toggles (dashicons, oEmbed, RSS, XML-RPC, jQuery Migrate, REST auth). | |
| 491 | -- New: Database module — optimize tables, scheduled cleanup, autoload analysis. | |
| 492 | -- New: CDN module — pull-zone URL rewriting. | |
| 493 | -- New: Cloudflare module — zone connect, auto-purge, dev-mode toggle. | |
| 494 | -- New: Object Cache module — Redis / Memcached config + status + flush. | |
| 495 | -- New: Browser Cache module — Cache-Control + Expires headers. | |
| 496 | -- New: Settings search across the entire dashboard with keyword highlighting. | |
| 497 | -- New: 3-step setup wizard on first activation with preset chooser and benchmark. | |
| 498 | -- New: Sidebar grouping under domain headers (Cache / Performance / Network / Insights / Tools). | |
| 499 | -- New: Sidebar tooltips + search shortcut in the collapsed rail. | |
| 500 | -- New: xspeed_branding filter — agencies can rebrand the dashboard. | |
| 501 | -- New: xspeed_cache_skip_for_post + xspeed_cache_expiry_for_post filters. | |
| 502 | - | |
| 503 | -Pro-essentials (everything xSpeed Pro depends on, bundled here so any Pro release works against this single Free version): | |
| 504 | -- New: xspeed_module_descriptor filter — Pro hooks this to swap its panels to LicenseLockedPanel when license is invalid. | |
| 505 | -- New: AI Privacy module — GDPR off-switch + xspeed_ai_can_collect_data filter that Pro AI features must consult before recording visitor data. | |
| 506 | -- New: Pro upsell teasers — in-context inline cards on Cache, Minify, Lazy Load, Browser Cache and Disable Bloat panels. | |
| 507 | -- New: Locked Pro module rows in the sidebar — shows what Pro offers with a clear upgrade prompt. | |
| 508 | -- New: Pro Audit on the Cache panel — site-specific scan listing the top Pro features that would help THIS site, with severity chips and concrete reasons (not generic marketing copy). | |
| 509 | -- New: Sidebar slot for the license module (appears when xSpeed Pro is installed). | |
| 510 | -- New: Global 36px form-control height baseline across the dashboard. | |
| 511 | -- New: filemtime() cache busting on admin asset URLs. | |
| 512 | - | |
| 513 | -Improvements & fixes: | |
| 514 | -- Improved: React panel registry — modules auto-render in the dashboard. | |
| 515 | -- Improved: Portal-based save indicator — zero layout shift. | |
| 516 | -- Improved: Distribution zip prunes dev dependencies (composer install --no-dev). | |
