Multi-Debrid-Downloader/CHANGELOG.md

# Changelog

All notable changes to Multi-Debrid Downloader are documented in this file.

## [2.0.66] - 2026-08-23

### AllDebrid authentication

- Replace the legacy website and cookie workflow with AllDebrid's official browser PIN authorization.
- Store the issued API key securely and use the official API for account details, host availability, link inspection, and link unlocking.
- Close the authorization window automatically after activation while keeping manual close, timeout, and repeated-open behavior deterministic.
- Require existing legacy browser-login configurations to authorize again instead of treating an empty session as a usable account.

### Account status

- Validate AllDebrid API and browser-authorized accounts through the official user endpoint.
- Display and persist username, email address, premium state, and expiration time in the account table.
- Include AllDebrid in active-account checks, full-account checks, direct row checks, and activation checks.
- Preserve the PIN-issued API key while editing a browser-authorized account.

### Download scheduling and recovery

- Remove the unconditional three-second delay before every AllDebrid download while continuing to honor live simultaneous-download limits reported by the provider.
- Treat unavailable links and unsupported link or host responses as terminal item failures without retrying unrelated downloads.
- Treat invalid, missing, blocked, banned, server-restricted, and IP-restricted credentials as terminal authentication failures without provider cooldowns.
- Preserve official AllDebrid error codes alongside their messages so retry and cooldown decisions remain precise.

## [2.0.65] - 2026-08-23

### Extract now behavior

- Extract only archive sets that are already complete on disk without starting or re-queueing downloads.
- Skip incomplete multipart sets while leaving every queued, failed, or missing part unchanged.
- Start every currently extractable package in a multi-selection even when other selected packages are not ready.
- Extract complete sets from a package immediately while its unrelated incomplete sets continue waiting for a later download.
- Keep the existing error response when none of the selected packages contains a complete extractable archive set.

### Compatibility correction

- Remove the automatic missing-archive download repair introduced in 2.0.64 so `Extract now` remains a strictly local post-processing action.

## [2.0.64] - 2026-08-23

### Manual extraction repair

- Turn `Extract now` into a recovery action when archive files from an earlier failed extraction are no longer available locally.
- Re-download only missing archive parts while preserving complete sibling parts and unrelated finished files.
- Extract already complete archive sets immediately while missing sets from the same package download in parallel.
- Include queued, failed, cancelled, and reconnecting multipart siblings in the same selected repair run.
- Keep manual extraction recovery pending across download failures, Stop, application restarts, and disabled automatic extraction.
- Resume extraction automatically after every required repair item finishes successfully.
- Allow direct retries from failed child archive rows as well as selected parent packages.

### Lifecycle integrity

- Persist manual repair intent and validated item IDs in session state and local full backups.
- Validate persisted repair IDs against their owning package during session loading.
- Keep failed repair runs and later successful retries in separate package generations and run contexts.
- Prevent pending repairs from producing premature successful package or run results.
- Clear repair intent only after a terminal extraction attempt, while preserving it across aborts and disk-capacity retries.
- Revalidate accounts and lifecycle state immediately before committing a repair batch.

## [2.0.63] - 2026-08-23

### Archive recovery and password handling

- Detect English, German, and misdecoded CRC and checksum failures from native and JVM extractors.
- Corroborate archive corruption across independent extraction backends and re-download only the named damaged multipart volume once per package generation.
- Keep encrypted archives and genuine wrong-password results out of destructive re-download recovery.
- Try every real RAR5 password candidate even when archive metadata does not reliably report encryption.
- Distinguish corrupted encrypted RAR and ZIP data, missing volumes, locked files, and open failures from incorrect passwords.
- Remove redundant full password passes and bound package recovery to one deduplicated retry set.
- Report password-attempt progress without exposing candidate values and isolate failing progress observers from the extraction process.
- Parse JVM daemon requests safely for passwords containing JSON metacharacters and Unicode.
- Remove successful-password payloads from the JVM protocol and redact diagnostic buffers before any error can reach logs.

### Extraction lifecycle and data safety

- Resume extraction automatically after temporary disk-capacity waits, including manual archive selections, with generation-, owner-, and timer-safe retry plans.
- Keep Stop, shutdown, disabled packages, stale callbacks, and changed run owners from restarting old extraction work.
- Preserve retry, pacing, disk, and provider cooldowns across Pause and Resume.
- Make standalone manual extraction stoppable through the normal toolbar lifecycle.
- Reject missing, incomplete, ambiguous, or non-archive manual targets before starting any selected batch.
- Resolve opaque archive files by signature without mutating files during preflight and commit valid batch plans atomically.
- Keep full-package cleanup enabled for complete manual extraction while protecting partial selections and packages with open downloads.
- Convert unexpected post-processing exceptions into deterministic extraction failures instead of successful package results.
- Requeue interrupted integrity checks after restart and clear stale transient post-processing labels.

### Cleanup and queue isolation

- Preserve independent downloads that happen to share the same package filename during startup recovery.
- Honor recycle-bin cleanup for previously extracted archives instead of deleting them permanently.
- Protect files owned by other packages in shared output folders, including archive companions, and verify file identity immediately before cleanup.
- Reset a corrupted download only after its old file was successfully removed or quarantined.
- Keep selected download runs scoped when packages are disabled, added later, or waiting for unrelated extraction work.
- Prevent selective starts from launching or stopping post-processing for other packages.

### Status, IPC, and release integrity

- Prioritize active downloads, integrity checks, extraction, password search, finalization, cleanup, and disk waits over historical sibling errors while retaining full details in tooltips.
- Keep pending, waiting-for-parts, active extraction, and historical failure states visually distinct after restart.
- Translate the complete dynamic extraction status set in German and English.
- Validate manual extraction IPC requests in a side-effect-free trusted handler and propagate stale or invalid selections as actionable errors.
- Compile the bundled JVM extractor before every main and Windows release build and reject stale source/class combinations.
- Verify every shipped JVM class, source digest, and library byte-for-byte in unpacked, Setup, and Portable release artifacts.

## [2.0.62] - 2026-08-23

### Manual extraction

- Run package and child archive extraction while downloads are stopped or paused and while sibling downloads remain open.
- Validate manual targets before replacing stale post-processing, then drain the previous extractor and coordinator before starting the new operation.
- Return actionable manual extraction errors through IPC instead of silently leaving items pending.
- Keep queued and delayed sibling downloads unchanged when starting or stopping a selected-item run.

### Archive progress and recovery

- Preserve password-attempt status across progress pulses and show the real finalization percentage instead of counting an active archive as complete.
- Include finalization progress in the package progress bar and retain archive names, elapsed time, and counters in tooltips.
- Retry complete archive sets that were previously marked attempted without a terminal extraction result.
- Add automatically recovered archive parts to the active run so every reset file is downloaded again.

### Package status

- Replace misleading aggregate counts such as `20 retries` with the actionable `Retrying link conversion` package state.
- Keep mixed extraction failures concise while retaining detailed item-level attempts and diagnostics.

## [2.0.61] - 2026-08-23

### RAR extraction reliability

- Recognize explicit WinRAR directory entries even when the native listing omits trailing path separators.
- Preserve strict file-directory collision protection by matching typed directory entries with counted archive occurrences.

### Windows persistence

- Retry short-lived Windows file locks while atomically saving the notification outbox during runtime and startup.

## [2.0.60] - 2026-08-22

### Manual extraction

- Extract a selected archive part together with its complete multipart set instead of requiring the parent package action.
- Extract multiple selected packages in one action and keep each archive set isolated by its full source path.
- Re-read the current archive password list for every manual retry and keep unrelated failed archives untouched.

## [2.0.59] - 2026-08-22

### Extraction reliability

- Recognize successfully extracted WinRAR, RAR, and 7-Zip files even when native progress output contains control characters or no parseable completion line.
- Prevent completed extractions from being reported as `No extracted files detected` and allow affected packages to be retried normally after updating.
- Preserve extractor-specific renamed filenames across shortened Windows extraction paths.
- Keep 7-Zip directory structures intact when RAR flat extraction is active and reject colliding flat RAR targets before extraction starts.

## [2.0.58] - 2026-08-22

### DLC drag and drop

- Restore direct DLC drag-and-drop imports into Downloads without routing dropped containers through the link collector preview.
- Resolve dropped file paths through Electron's supported preload bridge instead of relying on renderer-only file properties.
- Bound explicit link collector metadata enrichment so unavailable hoster checks cannot leave the interface permanently busy.

## [2.0.57] - 2026-08-22

### Window appearance

- Force the native Electron window theme to dark so the Windows title bar remains black across local, server, and Remote Desktop user profiles.

## [2.0.56] - 2026-08-22

### Notification Center

- Added rich Discord embeds for final package results, run summaries, remaining-volume alerts, and confirmed download stalls and recoveries.
- Wait for downloads, extraction, remuxing, cleanup, and deferred post-processing before reporting a package or run as finished.
- Persist pending notifications across restarts with ordered delivery, bounded retries, rate-limit handling, expiration, and a controlled shutdown drain.
- Support immediate package notifications or two-minute success digests while always delivering enabled failure notifications immediately.
- Added configurable run-scoped remaining-volume, download-stall, cooldown, and recovery alerts that ignore expected waits and short self-healing interruptions.
- Expanded History with separate download, extraction, remux, post-processing, and total durations plus final file, archive, part, output, and failure-phase details.
- Keep webhook details, local paths, account data, and credentials out of persisted notification events and failure messages.

- Replaced the one-time Downloads scheduler with a recurring local-time schedule that can begin today or tomorrow.
- Persist daily schedules across restarts and reconcile them after startup, account changes, suspend, and resume.
- Prevent duplicate starts for the same local day while handling daylight-saving changes, missed dates, empty queues, active runs, unavailable accounts, and retryable start failures.
- Added strict time validation, a next-start countdown, and visible save errors.

### Stop and restart lifecycle

- Serialize full-queue, package, and item starts through one lifecycle so starts requested during stopping run once after existing work drains.
- Prevent late recovery callbacks and stale task finalizers from reviving stopped work or replacing a newer run.
- Release cancelled Real-Debrid, AllDebrid, and BestDebrid web waits without blocking later requests.
- Show the current lifecycle phase, reason, provider retry countdown, pending start, and remaining work.
- Keep active and deferred post-processing bound to the run that owns it.

### Interface polish

- Added coordinated fade and size transitions when package rows expand or collapse while respecting the animation preference.
- Added global expand and collapse actions to Downloads and the link collector, including packages outside the active filter.
- Kept the Downloads package action visible in a responsive toolbar and disabled it for an empty queue.
- Changed contextual help to open on pointer hover or keyboard focus and grouped download filters into a compact sidebar section.

### Extraction safety and coordination

## [2.0.53] - 2026-08-21

### In-app updates

- Started the verified NSIS installer directly before application shutdown so Windows Server and RDP process-job cleanup cannot terminate an intermediate PowerShell launcher.
- Kept the running application open when Windows rejects the installer process instead of reporting a successful update and quitting without an installer.
- Delegated the complete process handoff to the installer with a 60-second graceful wait and a verified post-termination wait before replacing application files.

## [2.0.52] - 2026-08-21

### Rolling account statistics

- Added a true rolling Last 24 Hours range directly after Today in Statistics.
- Attributed downloaded traffic to the exact Real-Debrid, Mega-Debrid, or Debrid-Link account that produced each direct link.
- Displayed the known account username with its provider while retaining safe fallback labels for accounts without checked identity data.

- Changed the Update available button from blue to green.

### Release verification

- Added real Windows process-order and installed-package version coverage for the complete update handoff.
- Required a fresh application build after the release version changes before packaging the installer.

## [2.0.50] - 2026-08-21

### In-app updates

- Removed multi-selected history entries through one validated IPC request and one atomic history-file update.
- Preserved configured history limits above 500 entries during single and bulk removal operations.

### Remaining volume

- Added a translated hover explanation when the remaining download volume contains files whose sizes are not known yet.

## [2.0.47] - 2026-08-20

### Live updates

- Standardized running download snapshots and progress metrics on a 750 ms cadence for every queue size.
- Aligned session volume, remaining volume, speed, ETA, the header speed sparkline, and the bandwidth chart to the same refresh interval.
- Removed the extra active-download renderer delay so the UI presents each completed snapshot immediately without stacking latency.

## [2.0.45] - 2026-08-19

### Account availability

- Kept a configured Real-Debrid account pool authoritative when every account is disabled instead of reviving legacy browser-login fields.
- Released stale in-memory Real-Debrid cooldown and sticky state when an account is explicitly re-enabled so the Start action becomes available without restarting the application.
- Preserved configured per-account daily limits and usage while refreshing only transient runtime state.

## [2.0.44] - 2026-08-17

### Live updates

- Reduced visible download, remaining-volume, speed, ETA, and availability refresh churn for queues with 250 or more items by using a calm 500 ms cadence.
- Updated live speed sparklines and the bandwidth chart to redraw every 500 ms instead of every 250 ms.

- Added independent account activation, daily limits, daily usage, lifetime usage, status records, identity details, editing, removal, and credential reveal controls.
- Migrated existing single-account Real-Debrid settings and browser sessions into the new pool without discarding saved credentials or account status.
- Assigned opaque account identifiers and kept API tokens, browser tokens, cookies, and credential-derived fingerprints out of renderer state and diagnostics.

### Rotation and recovery

- Rotated eligible Real-Debrid API and browser accounts with fair ordering, sticky reuse, in-flight exclusion, account cooldowns, and daily-limit enforcement.
- Continued within the same conversion request after account-specific authentication, rate-limit, timeout, and transport failures.
- Kept provider-wide hoster failures and permanent link failures from cooling down or rotating otherwise healthy accounts.
- Attributed downloaded traffic to the exact account that generated the unrestricted link while preserving provider-wide totals.

- Preserved Real-Debrid usernames and email addresses independently in browser-account status rows.
- Prevented manually closed Real-Debrid login windows from reopening through queued or repeated work.
- Restricted browser window creation to explicit login actions so activation, status checks, downloads, missing sessions, and fair-use failures remain noninteractive.
- Cleaned up aborted, failed, deleted, and superseded browser sessions without allowing delayed probes to restore stale tokens or status records.

### Interface and downloads

- Added precise service filtering and alphabetical service ordering to the account-add dialog.
- Kept Real-Debrid API and browser-login choices available after another Real-Debrid account has already been configured.
- Continued link availability checks after downloads start so items cannot remain stuck on Checking while actively downloading.

- Simplified account menu headings to one hoster and access-type label without dangling separators or empty identity fields.

### Downloads and queue controls

- Moved the Remaining metric above the all-time Total value in the download summary.
- Kept the currently selected priority as a disabled no-op so choosing it does not close the package context menu.
- Reordered high, standard, and low priority packages consistently while preserving stable order inside each priority group.

### History and interface

- Rebuilt the history table around one shared resizable grid so headers, rows, expanded details, and horizontal scrolling stay aligned.
- Persisted history column widths and kept them responsive across compact and wide windows.
- Anchored the history Action column to the table edge and aligned size values directly below their header.
- Reworked expanded history details into a cleaner grouped surface for provider, files, duration, average speed, target folder, and source URLs.
