- Added a Remaining metric for unfinished download volume, with a lower-bound indicator when some file sizes are still unknown.

## [2.0.36] - 2026-08-14

### Download performance

- Restored the proven 2.0.28 download-processing baseline after later builds caused severe throughput drops and prolonged disk-wait states during large parallel queues.

- Revalidated the complete client and backup API test suites before publication.

## [2.0.28] - 2026-08-12

### Startup reliability

- Fixed Electron security registration so native WebContents and session APIs retain their required receiver during application startup.
- Fixed packaged renderer IPC validation for case-insensitive Windows file paths.
- Added explicit startup and renderer-load error logging for future launch diagnostics.

## [2.0.27] - 2026-08-12

## [2.0.26] - 2026-08-12

### Log storage

- Added a configurable log location in AppData or in a dedicated Desktop folder.
- Migrated recognised log files safely when changing location while keeping settings, credentials, and runtime data in AppData.

## [2.0.25] - 2026-08-12

### Credential and application security

- Encrypted persisted provider credentials with the operating system credential protection and migrated legacy plaintext values safely.
- Removed provider secrets from renderer snapshots, account-check responses, settings backups, support diagnostics, and copied account details.
- Added passphrase-protected local backup encryption while keeping legacy backup import available without writing the legacy format again.
- Hardened Electron navigation, redirects, permissions, popup handling, remote-login windows, and IPC sender validation.
- Restricted remote diagnostics to loopback by default, Bearer authentication, POST-only mutations, rate limiting, non-cacheable responses, and token-free support URLs.

### Storage reliability

- Added volume-aware capacity reservations before download writes, archive extraction, and media remux operations.
- Accounted for concurrent reservations and a configurable safety margin so parallel work cannot overbook the same volume.
- Parked capacity-blocked work without consuming regular retry attempts and exposed structured disk-wait state for automatic recovery.

### Large queue performance

- Virtualized package and file rows with fixed row heights and overscan to keep very large queues responsive.
- Preserved logical range selection, select-all behavior, column dragging, context actions, expansion state, and inline renaming outside the rendered viewport.
- Kept the existing scroll container and limited DOM work without adding another runtime dependency.

### Status and reliability

- Removed archive names from visible finalization progress in both German and English while retaining compact phase progress.

## [2.0.24] - 2026-08-11

### Download queue

- Kept every package in its existing visible queue position when downloads start, finish, pause, retry, or change status.
- Removed status-driven package grouping and the obsolete automatic progress-sorting setting.
- Blocked start, package start, item start, and resume actions when no active usable download account is available.

- Added a dedicated disk-wait recovery path for full, quota-limited, temporarily busy, and stalled write targets.
- Retried disk-blocked downloads automatically after storage becomes writable without consuming the normal download retry budget.
- Prioritized `Waiting for disk` at package level when one or more files are blocked by storage.
- Reported completed downloads with extraction failures as failed packages instead of showing a misleading completed file count.
- Removed redundant provider names from start, download, data-wait, and disk-wait status labels while preserving diagnostic details.

### Reliability and testing

- Added regression coverage for unavailable and disabled accounts, resume protection, disk-write recovery, retry accounting, package-level disk waits, extraction failures, compact runtime statuses, and stable queue ordering.
- Verified the complete client suite, TypeScript compilation, production build, release metadata, archive contents, and application self-check.

## [2.0.23] - 2026-08-11

### Update experience

- Changed the available-update header action to a dedicated light-blue treatment with dark high-contrast text.
- Added cumulative release notes for every stable version newer than the installed application, ordered from newest to oldest.
- Excluded draft releases, prereleases, the installed version, and older versions from cumulative update notes.

- Removed archive filenames from visible password-cracking progress while retaining full technical details in the status tooltip.
- Kept active packages in their activation order and appended newly active packages behind downloads that were already running.

### Account handling

- Separated Mega-Debrid API and Web Login credential pools so adding, editing, disabling, or removing one mode no longer changes the other mode.
- Migrated legacy shared Mega-Debrid credentials and disabled-account states into the explicitly enabled access mode, falling back to the preferred mode only for ambiguous legacy configurations.
- Kept mode-specific account availability and provider selection synchronized with live settings changes.
- Applied added, edited, disabled, and re-enabled Mega-Debrid accounts to the active scheduler without requiring an application restart.
- Invalidated cached Mega-Debrid Web Login sessions immediately when Web credentials change, prevented older in-flight, retried, and queued requests from restoring invalidated cookies, and left API-only changes isolated.
- Released only Mega-Debrid reset-parked queue items when a usable account pool becomes available while preserving unrelated retry delays.
- Prevented new Mega-Debrid account forms from exposing stored credentials in an unrelated token field.
- Removed both mode-specific Mega-Debrid credential pools from persisted settings when credential storage is disabled.
- Synchronized item and package status immediately when a provider retry is queued.

### Reliability and testing

- Kept the latest release notes as a fallback when the release history cannot be loaded.

- Improved dense download views with responsive status labels, clearer progress text, and safer package expansion behavior.

### Downloads and telemetry

- Removed the redundant Add links toolbar action so Start is now the first download control.
- Removed the additional renderer delay for large active queues, allowing manager telemetry to appear without a second buffering interval.
- Kept the header sparkline, package speeds, and sidebar speed synchronized from the same package telemetry snapshot.

- Reworked the Downloads workspace for substantially denser queues, smoother interaction, clearer selection, and responsive column sizing.
- Rebuilt the project README with current documentation and a sanitized screenshot of the application.

### Downloads workspace

### Navigation and animation

- Added a shared sliding selection indicator to the main navigation.
- Added matching sliding indicators to Downloads filters, Settings sections, History ranges, and Statistics periods.
- Fixed initial category selection so newly opened views appear selected immediately instead of fading in from an empty state.

- Hid the redundant Files display mode and retained a focused package workflow.
- Improved header, menu, account-table, progress-value, and status text contrast.
- Unified the speed indicator with the rest of the application shell.
- Fixed duplicated Speed wording in the Downloads sidebar summary.

### Localization
