Update Log

Engine-level diagnosis of the live download flow, plus a content expansion of the Knowledge Hub.

• Fixed broken covers — TikWM requests no longer ask for its proxied paths (web=1); covers and media now come from the platforms' own CDNs, which load reliably.
• Faster TikTok failures — the resolver's second probe round is skipped when the first round was pure rate-limiting, cutting several seconds off every failed lookup.
• Removed a dead upstream — the retired iesdouyin iteminfo endpoint no longer adds a round-trip to every Douyin lookup.
• Full resolver logging — every layer now reports its verdict to the edge logs, so throttling vs. dead upstreams are tellable at a glance.
• Smarter Douyin retry — the final retry now waits out the free upstream's 30-second quota window instead of burning attempts inside it, with a progress toast.
• URL canonicalization — canonical tags, structured data, internal links and the sitemap now all agree on one URL per page (the pretty form Cloudflare Pages serves), ending duplicate-content ambiguity for crawlers.
• Five dedicated downloader pages — keyword landing pages for Douyin video, TikTok video, TikTok MP3, Douyin photos and TikTok photos, each with its own tool entry, how-to steps and FAQ; the homepage tool now accepts /?url= deep links so these pages open straight into a running download.
• Two new guides — "Is That Free Downloader Safe?" and "What Douyin & TikTok Know About You", plus expanded About, Contact, and hub pages.
