| 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. | |

| 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 | |

| 196 | +Yes. xSpeed Cache works on Apache, nginx, LiteSpeed, IIS and any standard PHP host. GZIP auto-configures on Apache and LiteSpeed, and a ready-to-paste config snippet is provided for nginx and IIS. | |
| 177 | 197 | |
| 178 | -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. | |
| 198 | += Will it conflict with LiteSpeed Cache? = | |

| 200 | +No. xSpeed Cache detects the LiteSpeed Cache server module and steps back to avoid conflicts. | |
| 181 | 201 | |
| 182 | -Yes. Add `/cart`, `/checkout`, and `/my-account` to the Excluded URLs list and xSpeed Cache will skip caching those pages. Logged-in customers are never served cached pages regardless. | |
| 202 | += Is it safe for WooCommerce? = | |
| 183 | 203 | |
| 184 | -= Does it work with my server? = | |
| 204 | +Yes. Logged-in customers and checkout pages are never cached, and you can exclude specific URLs such as `/cart`, `/checkout` and `/my-account`. | |

| 208 | +Yes. Each site in the network gets its own cache and settings. | |
| 189 | 209 | |
| 190 | -Yes. Each site in the network has its own independent cache and settings. | |
| 210 | += Is this a WordPress MCP adapter? = | |
| 191 | 211 | |
| 192 | -= Will it conflict with LiteSpeed Cache? = | |
| 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. | |
| 193 | 213 | |
| 194 | -No. xSpeed Cache 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. | |
| 214 | += Can I connect Claude to it? = | |
| 195 | 215 | |
| 196 | -= How do I exclude a page from being cached? = | |
| 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. | |
| 197 | 217 | |
| 198 | -Go to **xSpeed Cache → Settings**, paste the URL path (e.g. `/cart`) into the Excluded URLs field — one path per line. Changes save automatically. | |
| 218 | += Is xSpeed Cache the best free WordPress cache plugin? = | |
| 199 | 219 | |
| 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. | |
| 221 | + | |
| 222 | += Can it replace my separate WordPress page speed plugin and CDN plugin? = | |
| 223 | + | |
| 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. | |
| 225 | + | |
| 226 | += Will it help my Core Web Vitals? = | |
| 227 | + | |
| 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. | |
| 229 | + | |
| 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 | -**Actionable dashboard insights, richer AI tooling, and smarter health detection.** | |
| 312 | +**Consent-manager scripts marked late are now always left alone, below-fold sections skip rendering work until they are needed, and xSpeed's MCP server shares a site cleanly with other MCP plugins.** | |
| 281 | 313 | |
| 282 | -Dashboard & Admin UX: | |
| 283 | -- New: Impact hero showing the real-world speed gain your cache is delivering, with a one-click next-best-action to apply the top recommendation. | |
| 284 | -- New: Benchmark history and daily hit-ratio trend charts, annotated with the setting changes that moved them. | |
| 314 | +Optimization: | |
| 315 | +- New: Below-fold sections are rendered lazily with content-visibility: auto, so the browser skips their layout and paint work until they scroll into view. | |
| 316 | +- New: Block-editor stylesheets are stripped from anonymous frontend pages that do not use any blocks. | |
| 317 | +- Fixed: Scripts that another plugin marks data-no-optimize or data-no-minify late — as consent managers such as Borlabs Cookie do — are restored to their original URL and left alone by minify, defer and delay, however late the marker is stamped. | |
| 285 | 318 | |
| 286 | 319 | AI / MCP: |
| 287 | -- New: Purge a single URL, read site health, test the object cache connection, and verify Cloudflare credentials directly from your AI assistant. | |
| 320 | +- Improved: The AI & agents screen now leads with the MCP server and says what each of its tools does, with descriptions shown in full. | |
| 321 | +- Improved: An assistant already connected over OAuth may ask for approval once more after updating — nothing needs re-entering, and read-only connections stay read-only. | |
| 322 | +- Fixed: An AI assistant can now connect to xSpeed and to another MCP plugin on the same site. xSpeed's OAuth details moved to an address of their own under /xspeed/mcp, and the site-wide address is handed over as soon as another plugin asks for it — where nothing else wants it, xSpeed keeps answering there. | |

| 289 | -Health: | |
| 290 | -- New: Detects third-party cookies that would poison the page cache and names the plugin responsible. | |
| 291 | -- New: Warns when the cache lifetime is shorter than the preloader interval, which would leave pages permanently uncached. | |
| 292 | - | |
| 293 | -Optimization: | |
| 294 | -- New: Delay individual scripts by name instead of all-or-nothing, so you can defer heavy third-party embeds while leaving critical scripts alone. | |
| 295 | -- Fixed: Lazy-loaded images now get correct width and height even when the theme strips WordPress' image size class, preventing layout shift. | |

| 431 | -LiteSpeed: | |
| 432 | -- Fixed: On LiteSpeed/OpenLiteSpeed, xSpeed Cache 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. | |

| 435 | -Cache hit counting & stats: | |
| 436 | -- 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%. | |
| 437 | -- Fixed: Cache MISSes are now recorded inline so the hit-ratio stat reflects reality instead of being pinned at 100%. | |
| 438 | -- Fixed: PHP-served cache HITs are counted correctly and the drop-in device-bucket desync is resolved. | |
| 439 | -- 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). | |
| 440 | - | |
| 441 | -Nginx: | |
| 442 | -- 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`. | |
| 443 | -- 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. | |

| 454 | -- Fixed: Google Fonts — no longer double-appends `display=swap` on entity-encoded hrefs. | |
| 455 | -- Fixed: Settings now strictly validate boolean fields instead of casting, preventing bad values from silently becoming `true`/`false`. | |
| 456 | -- Fixed: Object Cache — core option groups marked non-persistent so the drop-in can always be deactivated; degraded backends detected honestly. | |
| 457 | -- Improved: Static-rewrite SSL probe verifies the certificate and no longer blocks admin page loads. | |

| 461 | -**One-click object cache, parity exclusions & admin polish.** | |
| 462 | - | |
| 463 | -Object Cache: | |
| 464 | -- New: One-click Object Cache setup for Redis and Memcached — tests the connection, installs its own drop-in, and writes the wp-config constants (fully reversible). No drop-in plugin or PHP extension required. | |
| 465 | -- Improved: Dashboard now reports a degraded object cache honestly when the drop-in can't reach its backend, instead of implying caching is healthy. | |
| 466 | - | |
| 467 | -Admin UX: | |
| 468 | -- New: WP admin submenu now mirrors the in-dashboard navigation, so the menu and dashboard tabs stay in sync. | |
| 469 | -- Improved: Settings changes apply live across dashboard navigation — no full page reload needed. | |
| 470 | -- Improved: Menu icon now recolors to the active accent state correctly. | |
| 471 | -- Improved: Success notifications are anchored to a single consistent position (bottom-center). | |
| 472 | -- Fixed: Long panel titles no longer push the subtitle off-screen. | |
| 473 | -- Fixed: Number-input spinners render consistently across browsers (Firefox no longer clips the value). | |
| 474 | - | |
| 475 | -Cache exclusions: | |
| 476 | -- 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. | |
| 477 | -- New: Exclusion rules now support regex via a `~` prefix (e.g. `~utm_[a-zA-Z0-9_-]+`), alongside glob and substring, with ReDoS guards. | |
| 478 | - | |
| 479 | -Bug fixes: | |
| 480 | -- 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). | |
| 481 | - | |
| 482 | -License: | |
| 483 | -- Fixed: Activating a Pro license now unlocks the Pro panels immediately — no full page reload needed. | |

| 487 | -**Topology-aware UX, nginx HIT counting, admin polish.** | |
| 488 | - | |
| 489 | -Cache topology & UX: | |
| 490 | -- 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. | |
| 491 | -- New: Unified nginx server-block snippet — one consolidated, copy-pasteable snippet (collapsible in the UI) replaces the previous fragmented sections. | |
| 492 | -- 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. | |
| 493 | -- 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. | |
| 494 | -- Improved: Browser Cache notice is topology-aware and renders its snippet in a proper code block. | |
| 495 | - | |
| 496 | -Admin UX: | |
| 497 | -- New: Third-party admin notices are suppressed on xSpeed Cache admin screens (`page=xspeed*` only) — other plugins' "rate us" / promo notices no longer crowd the xSpeed Cache dashboard. | |
| 498 | -- New: Aligned sticky title-bar across the sidebar and content panels for a cleaner scroll experience. | |
| 499 | -- Improved: Browser Cache + GZIP notices probe-gate themselves — once the underlying issue is resolved, the notice dismisses on its own instead of lingering. | |
| 500 | - | |
| 501 | -Benchmark: | |
| 502 | -- 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. | |
| 503 | - | |
| 504 | -= [1.0.2] – 2026-06-02 = | |

| 506 | -**Static-rewrite cache, Site Health & Fonts.** | |
| 507 | - | |
| 508 | -Static-rewrite cache + Site Health: | |
| 509 | -- 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). | |
| 510 | -- 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. | |
| 511 | -- 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. | |
| 512 | -- New: LiteSpeed LSCache coexistence — xSpeed Cache detects LSCache's server-level module and steps back instead of double-caching. | |
| 513 | -- New: Active rewrite probe — Health module pings the cache directory and confirms the rewrite is actually serving static bytes (not just present in .htaccess). | |
| 514 | -- New: WordPress Site Health integration — Tools → Site Health now lists an xSpeed Cache check covering static-rewrite status + nginx config requirements. | |
| 515 | -- New: Persistent banner — Cache panel warns the admin when caching is on but the static-rewrite block isn't engaged (slow fallback path). | |
| 516 | -- New: Copy-to-clipboard button on every config-snippet panel (nginx, GZIP, object-cache). | |
| 517 | - | |
| 518 | -Fonts: | |
| 519 | -- 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. | |
| 520 | -- New: FontsModule tests covering the swap rewrite + preload `<link>` emission. | |
| 521 | - | |
| 522 | -Improvements & fixes: | |
| 523 | -- Improved: Server-type detection is cached so CLI / cron contexts see the same server type as web requests. | |
| 524 | -- 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. | |
| 525 | -- Improved: Plugin Check pass — i18n textdomains, WP_Filesystem coverage, SQL preparation, sanitization, and plugin/readme headers all cleaned up for WordPress.org review. | |
| 526 | -- Fixed: nginx snippet rewritten to avoid the try_files trap that broke pretty permalinks. | |
| 527 | -- Fixed: Rewrite condition normalized for trailing-slash + non-trailing-slash URLs. | |
| 528 | -- Fixed: WP-Rocket-style canonical pattern — server-level conditional rewrite. | |
| 529 | -- Fixed: Minify tag-rewrite filters bail in non-frontend contexts (REST / admin / cron). | |
| 530 | -- Fixed: wp.org release zip now ships `vendor/` — resolves the 1.0.1 activation fatal. | |
| 531 | -- Improved: Release pipeline rebuilt — `.distignore`-driven dist build, CI verify step, version-named artifact on every run. | |
| 532 | -- Improved: Plugin version read from the PHP header — single source of truth. | |

| 536 | -**Foundation release — full feature set + Pro hooks.** | |
| 537 | - | |
| 538 | -Module architecture + LiteSpeed parity floor: | |
| 539 | -- 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). | |
| 540 | -- New: Health module — 24-hour hit/miss counter + activity log. | |
| 541 | -- New: Preloader module — sitemap-driven cache warmer with content-publish auto-warm. | |
| 542 | -- New: Cache exclusion intelligence — glob URL patterns, cookie patterns, User-Agent bypass, ignored query parameters. | |
| 543 | -- New: Per-device cache (mobile-separate). | |
| 544 | -- New: Per-post cache rules — don't-cache + custom expiry meta box. | |
| 545 | -- New: Minification — CSS / JS / HTML minify, combine, defer JS, delay JS, async CSS, remove ?ver= query strings. | |
| 546 | -- New: Lazy Load module — images / iframes / videos + auto CLS-fix. | |
| 547 | -- New: Disable Bloat module — 6 ergonomic toggles (dashicons, oEmbed, RSS, XML-RPC, jQuery Migrate, REST auth). | |
| 548 | -- New: Database module — optimize tables, scheduled cleanup, autoload analysis. | |
| 549 | -- New: CDN module — pull-zone URL rewriting. | |
| 550 | -- New: Cloudflare module — zone connect, auto-purge, dev-mode toggle. | |
| 551 | -- New: Object Cache module — Redis / Memcached config + status + flush. | |
| 552 | -- New: Browser Cache module — Cache-Control + Expires headers. | |
| 553 | -- New: Settings search across the entire dashboard with keyword highlighting. | |
| 554 | -- New: 3-step setup wizard on first activation with preset chooser and benchmark. | |
| 555 | -- New: Sidebar grouping under domain headers (Cache / Performance / Network / Insights / Tools). | |
| 556 | -- New: Sidebar tooltips + search shortcut in the collapsed rail. | |
| 557 | -- New: xspeed_branding filter — agencies can rebrand the dashboard. | |
| 558 | -- New: xspeed_cache_skip_for_post + xspeed_cache_expiry_for_post filters. | |
| 559 | - | |
| 560 | -Pro-essentials (everything xSpeed Pro depends on, bundled here so any Pro release works against this single Free version): | |
| 561 | -- New: xspeed_module_descriptor filter — Pro hooks this to swap its panels to LicenseLockedPanel when license is invalid. | |
| 562 | -- New: AI Privacy module — GDPR off-switch + xspeed_ai_can_collect_data filter that Pro AI features must consult before recording visitor data. | |
| 563 | -- New: Pro upsell teasers — in-context inline cards on Cache, Minify, Lazy Load, Browser Cache and Disable Bloat panels. | |
| 564 | -- New: Locked Pro module rows in the sidebar — shows what Pro offers with a clear upgrade prompt. | |
| 565 | -- 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). | |
| 566 | -- New: Sidebar slot for the license module (appears when xSpeed Pro is installed). | |
| 567 | -- New: Global 36px form-control height baseline across the dashboard. | |
| 568 | -- New: filemtime() cache busting on admin asset URLs. | |
| 569 | - | |
| 570 | -Improvements & fixes: | |
| 571 | -- Improved: React panel registry — modules auto-render in the dashboard. | |
| 572 | -- Improved: Portal-based save indicator — zero layout shift. | |
| 573 | -- Improved: Distribution zip prunes dev dependencies (composer install --no-dev). | |
