Epsilon Download Manager 1.7.1

Epsilon Download Manager 1.7.1

Version 1.7.1 is an in-place upgrade. Existing settings, download links, history, queues, partial files, and browser integration are preserved.

Multi-Network reliability

• Fixed Windows adapter routing so a worker assigned to Ethernet, Wi-Fi, or tethering is explicitly routed through that interface instead of silently following the lowest-metric Windows route.
• Added a real transfer test for every selected adapter and per-network traffic labels in Download Details.
• Added controls for metered networks, daily usage, keeping one connection free, approval of newly detected networks, retry timing, and per-network colours.
• A failed adapter is temporarily removed from a download and retried later without failing the file.

Downloading and queues

• Added expected SHA-256 verification and queue selection to Add Download.
• Added a persistent “When I delete” preference. Completed files remain protected from disk deletion.
• Completed downloads are removed from schedule queues while remaining in download history.
• Scheduled queues use the configured simultaneous-download count instead of a fixed value.
• Improved pause/restart recovery and visible disk-loading progress.

BitTorrent

• Added BitTorrent protocol encryption (MSE/PE), IPv6 peer discovery from HTTP and UDP trackers, dual-stack incoming connections, persistent DHT contacts, and optional UPnP/NAT-PMP port mapping.
• Fixed upload back-pressure that could stall downloads.
• Torrent download and upload speed remain unlimited unless the user explicitly sets a limit.

Interface and localization

• Restyled Add Download, Add Torrent, Batch, Video, Website Grabber, Download Details, Intelligent Center, Download Complete, and delete prompts to match the v6 desktop design.
• Added the full Multi-Network settings panel and refreshed Options navigation.
• Improved English/Persian coverage, RTL layout, and dark-theme readability.

Packaging

• Chrome/Edge and Firefox extension packages are aligned to 1.7.1.
• The installer upgrades older Epsilon versions in place and keeps all application data.

Firefox extension

Install the Mozilla-approved extension from Firefox Add-ons.

Browser capture hotfix

The 1.7.1 files were refreshed on October 7, 2026 to fix the Add Download window failing to open for browser-captured links. The version and filenames remain 1.7.1. Existing settings and downloads are preserved when installing over 1.7.1.

Epsilon Download Manager 1.7.0

Version 1.7.0 is an in-place upgrade. Existing settings, download links, history, queues, partial files, and browser integration are preserved.

New interface

• Completed downloads are always kept on disk when removed from Epsilon.
• Added a command to reset a remembered delete choice.
• Added queue assignment, no-queue/start-now, and new-queue creation to both selection and context menus.

• Added a persistent seed-time limit and live application of torrent settings.
• Fixed selecting a previously skipped torrent file after the other files completed.
• Added BEP 19 HTTP(S) web-seed acceleration for single-file torrents.

Epsilon Download Manager 1.6.0

Epsilon Download Manager 1.6.0

Epsilon 1.6 introduces a new desktop design and strengthens the download engine while preserving in-place upgrades and existing user data.

New design

• Replaced the large theme-colored header, permanent sidebar, and IDM-style icon ribbon with a single minimal Canvas workspace.
• Added compact All, Active, Finished, and Queues filters above the full-width download table.
• Kept every previous command available through the Canvas controls, row menu, optional navigation panel, and More panel.
• Added a dedicated gauge icon to the compact top speed limiter.
• Reduced oversized rounded elements in favor of restrained rectangular controls and download rows.
• Made Platinum Blue the default theme for new installations.
• Added the Makan Lab theme, based on makanlab.tech: ink black, electric blue, and amber.
• Added Makan Lab theme support to the Chrome/Edge and Firefox extension interfaces.
• Restored a compact top-bar speed limiter with Unlimited, quick presets, custom values, and combined/per-file modes.
• Replaced the old delete confirmation dialog with a three-choice contextual action bar.
• Completed downloads are now removed from Epsilon without deleting their finished files from disk.

Engine and reliability

• Added optional Multi-Network segmented downloads across multiple connected adapters.
• A failing secondary network is dropped automatically and the download continues through a healthy route.
• Downloads wait for the internet connection to return without consuming their retry allowance.
• Strengthened resume-map durability by synchronizing data flushes with map snapshots.
• Made final file replacement atomic so an existing destination is not deleted before replacement succeeds.
• Uses independent HTTP/1.1 connections for segmented downloads where supported, with HTTP/2 fallback.
