Changelog

0.4.4 — 2026-08-02

Fixed

• Oversized segment recovery: when a server returns more bytes than the Range header requested (valid 206 with correct Content-Range but excess body data), the script now extracts the correct byte slice instead of failing. Previously this produced "Segment oversized: received 151 KB for 13.0 KB expected."
• Improved requestRange binary-data fallback: when the userscript manager does not populate response.response as an ArrayBuffer, the script now converts response.responseText to bytes reliably.

0.4.2 — 2026-08-02

Fixed

• False-positive interception on extensionless page links (e.g. Google search results): the script no longer intercepts links whose URL paths have no file extension unless the link text is a short (≤ 25 char), button-like download label. Real download buttons ("Download", "Download Now", etc.) continue to work.
• Links that point to obvious web pages (.html, .php, .asp, .aspx, etc.) are rejected immediately.
• Improved byte-range error message: now explains that the server does not support partial requests and suggests using "Browser download" instead.

0.4.0 — 2026-08-02

Added

• Userscript-manager command Parallel Download Manager: Download URL… for manually submitting a direct HTTP(S) download URL.
• Userscript-manager Status command showing whether the script is active, current save-mode capability, and the most recent click-detection decision.
• Recognition for clear download labels in link text, aria-label, and title: Download, Export, Get file, and Save file.
• Composed Shadow DOM link lookup using event.composedPath().
• Recognition for direct-file links that normally use target="_blank".
• README.md usage, setup, limitations, test guidance, and troubleshooting documentation.
• GREASYFORK_DESCRIPTION.md with revised listing content that matches the script’s actual behavior.

Changed

• Renamed Normal download to Browser download to make clear that it intentionally uses the site/browser download flow and Chrome’s download UI.
• Browser download now replays the intercepted original anchor or supported native control when possible, preserving page-specific behavior instead of always building a replacement anchor.
• Updated listing language from “any direct file link” and “replaces the browser’s default download” to accurately describe recognized direct links and the manual URL fallback.
• ETag and Last-Modified validators are now tracked and compared separately.
• Modal buttons now have 40 px minimum hit areas and consistent press feedback.

Fixed

• Fixed an invisible full-screen modal backdrop that continued to intercept pointer events after the dialog closed, making the underlying page unresponsive until reload.
• Fixed automatic detection intercepting ordinary navigation links whose surrounding anchor metadata happened to contain words such as “download” or “export.” Ambiguous new-tab links now remain native.
• Added narrow detection for exact Direct download actions, including extensionless endpoints and explicitly labeled new-tab downloads used by TestFile.org.
• Replaced the narrow exact-label allowlist with an evidence-based classifier covering common labels, extensionless download routes, button class/ID hints, and accessible download icons while filtering documentation and category links.
• On terminal download failure, active requests, retry timers, and partial output are aborted before the error is surfaced.
• Labeled opaque download links no longer require a download class or ID to be recognized.

Compatibility notes

• Chrome 138+ requires Allow User Scripts to be enabled for the userscript manager extension.
• Tampermonkey and Violentmonkey are the supported managers for this release. Other managers require separate verification.

0.3.0 — 2026-08-01

Added

• Initial release with range-verified segmented downloads.
• Parallel connection lanes, retries with rate-limit backoff, cancellation, and file-sink/Blob-sink save modes.
