Update Logs

Recent Updates

Add Features:

• Added IP Geolocation Query settings under System Settings → Security Settings → Upload Management, supporting custom API upload-IP lookup and ordered response-field composition for the saved upload address
• Added publicUrl to successful Upload API responses. When a default URL prefix is set, basic uploads and chunked-upload merge return this public access link

Optimization:

• Added a generic Worker Cache layer to the Workers deployment adapter based on business Cache-Control responses. Public GET/HEAD responses are checked in cache first, and cache misses run the original business route before storing responses with public, max-age/s-maxage
• Range requests now try to use an existing complete cached response first; cache misses pass through to the business response and do not store 206 partial responses, preventing partial content from polluting full-file cache entries

Security:

• Changed the directory tree and tag autocomplete APIs to private caching, preserving short browser caching while preventing authenticated APIs from entering the shared Workers cache

2026.06.15

Optimization:

• Range requests now try to use an existing complete cached response first; cache misses pass through to the business response and do not store 206 partial responses, preventing partial content from polluting full-file cache entries

Security:

• Changed the directory tree and tag autocomplete APIs to private caching, preserving short browser caching while preventing authenticated APIs from entering the shared Workers cache

2026.06.14

Add Features:

• Added IP Geolocation Query settings under System Settings → Security Settings → Upload Management, supporting enable/disable, custom API request parameters, and the {ip} placeholder for passing the upload IP
• IP Geolocation Query now supports JSON response field paths; the backend joins field values in order and writes the result to file metadata UploadAddress

2026.06.12

Add Features:

• Added publicUrl to successful Upload API responses. When a default URL prefix is set, basic uploads and chunked-upload merge return this public access link

2026.06.09

Security:

• Admin login, user login, and session checks now return 503 when security settings cannot be loaded, preventing fallback to an empty default authentication config
• Session max-age settings are now normalized on the backend; timestamp-like or out-of-range values fall back to 14 days to avoid Cloudflare KV expirationTtl range errors

Optimization:

• Added frontend validation for user and admin session max age in System Settings > Security Settings, restricting values to 1-3650 days

Fix Bugs:

• Fixed admin login returning HTTP 500 when an abnormal millisecond timestamp was used as the Cloudflare KV expirationTtl

2026.06.08

Fix Bugs:

• Fixed chunked uploads failing when some browsers cannot detect a file MIME type and the frontend sends an empty originalFileType; the upload form now falls back to application/octet-stream

2026.06.05

Optimization:

• Added fallback channel matching based on unique identity fields stored in legacy metadata, allowing files to keep resolving to the current Telegram, S3/R2, Discord, HuggingFace, or WebDAV channel configuration after a channel is renamed
• Added channel-name immutability hints in channel settings and disabled channel-name editing to prevent breaking the association between uploaded files and their channel configuration

Fix Bugs:

• Fixed large admin file lists stopping before all pages were appended even when later load-more requests succeeded
• Changed channel deletion confirmation into a risk warning that clearly states files associated with the deleted channel may become inaccessible

2026.06.03

Optimization:

• Reduced persisted file metadata for S3, Telegram, Discord, HuggingFace, WebDAV, and related channels by no longer storing fields that can be read from the current channel configuration
• Management file details now dynamically enrich S3Location, S3CdnFileUrl, HfFileUrl, WebDAVPublicUrl, and similar display fields from the current channel configuration, so displayed links refresh after config changes
• File read, delete, move, and rename operations now resolve credentials through the current channel configuration; legacy Telegram/TelegramNew records without ChannelName fall back to Telegram_env

Security:

• Management metadata, tag, allow/block list, move, rename, and backup restore write paths now consistently remove sensitive and config-derived fields, preventing old backups or legacy records from writing credentials back

Fix Bugs:

• Fixed file details still showing stale S3Location or CDN links after changing S3 endpoint/CDN configuration
• Fixed S3 move or rename failures potentially moving the database record even when the remote S3 operation failed

2026.06.02

Add Features:

• Added /upload/huggingface/completeMultipart to proxy HuggingFace LFS multipart completion for large direct uploads
• HuggingFace direct upload URL generation now rewrites multipart completion URLs to an internal endpoint, enabling multipart completion in Cloudflare Workers deployments

Optimization:

• Unified WebDAV credential resolution into the shared channel credential flow, so read, delete, move, and rename operations use the same configuration source

Security:

• Management file list, batch list, custom file list, and metadata APIs now filter sensitive S3, Telegram, Discord, HuggingFace, and WebDAV credentials from returned metadata
• File read, delete, move, and rename operations now prefer current channel configuration for credentials, reducing the need to store or expose credentials in file metadata
• WebDAVBaseUrl in metadata now strips URL userinfo to avoid leaking usernames or passwords through management API responses

Fix Bugs:

• Fixed HuggingFace direct upload URL requests requiring fileType; files without a MIME type now fall back to application/octet-stream
• Improved HuggingFace multipart completion target and parts validation so invalid requests return 400 instead of 500
• Fixed WebDAV public URL reads changing the original 404/403 status into 500 when the WebDAV API fallback also failed

2026.05.30

Fix Bugs:

• Fixed HuggingFace file HEAD responses returning Content-Length: 0; the handler now uses uploaded metadata (FileSizeBytes) to report the actual file size, improving browser and player media probing

2026.05.25

Add Features:

• Added an upload trend line chart to the system status page, showing uploads from the last 7 days by default
• Upload trends can be grouped by channel type or channel name, with a total uploads line
• Upload trends support date range filtering with a single-month calendar dialog; click twice to select start/end dates or manually enter the date range
• Dashboard file rename dialog now supports confirming with Enter

Optimization:

• Enhanced the indexinfo API with upload trend statistics, using linear aggregation into date buckets and capped point/series counts to avoid high CPU usage on the status page

2026.05.06

Fix Bugs:

• Fixed duplicate Content-Length response headers from the Docker native Node server when accessing /random through a reverse proxy, which could cause Nginx / Cloudflare to return 502

2026.05.01

Security:

• WebDAV internal calls now use a dedicated API Token instead of admin password Basic Auth, eliminating the risk of password hash leakage

Fix Bugs:

• Fixed off-by-one error in Docker deployment [[path]].js catch-all route matching, causing /dav/ and /file/ root paths to return 404
• Fixed WebDAV PROPFIND always reporting file size as 0 (was reading non-existent File-Size field, changed to FileSizeBytes)
• Fixed WebDAV PROPFIND file href missing /dav prefix, preventing clients from downloading files
• Fixed WebDAV PROPFIND missing getcontenttype property, preventing Alist and other clients from identifying file types and showing previews

2026.04.29

Security:

• Admin file previews no longer trust from=admin or same-origin Referer, and now require a verified admin session before allowing admin previews
• Manage APIs now get a default non-cacheable response header to prevent browser or CDN caching from causing stale state after GET-style management operations
• Reduced mutation response payloads for manage APIs to avoid returning unnecessary metadata or sensitive data from blocklist, tag, and API Token update endpoints

Optimization:

• Optimized data loading on the admin user management page: the user list API now aggregates IP summaries in a single pass and returns summary rows only, while per-user file records are lazy-loaded on row expansion to reduce Worker CPU usage and response payload size

Fix Bugs:

• Fixed blocklist/whitelist toggles in the admin panel potentially returning cached old responses, which could show success without updating the actual state

2026.04.28

Add Features:

• Added WebDAV storage channel, allowing third-party WebDAV services to be used as upload backends with upload, read, delete, move, rename, and channel-list support

Security:

• Session storage keys migrated to the manage@session@ prefix to prevent session data from entering the file index and backup exports

Fix Bugs:

• Fixed D1 adapter routing for manage@ configuration keys so blocklists, sessions, and other settings no longer get written to the files table
• Fixed D1 settings backup reads so manage@ settings data can be listed correctly

2026.04.27

Refactor:

• Reworked login page keyboard avoidance: replaced media query approach with visualViewport API to detect virtual keyboard, fixing false triggers on narrow screens without a keyboard
