This release adds the following new features:
- Greatly improved import from Trello to WeKan:
- Attachments now import. Trello attachment URLs require OAuth to download, so
WeKan could not fetch them. The Trello import page now has two separate file
fields: a .json field for a single Trello board, and a
.zip field for a package produced by the
Trello Card Attachments Downloader.
The .zip may contain one or more board .json files together with each
board’s attachments in a board-name subfolder. The .zip is uploaded over HTTP
and processed entirely on the server (the attachment bytes never travel over
the realtime WebSocket, which previously overflowed the connection and made
the page flicker): WeKan detects every board .json, matches each board to its
attachment subfolder by name, streams each file straight into the Default
file storage, imports all boards, then opens All Boards. The upload is guarded
against abuse — it rejects oversized uploads, zip bombs (too many files or too
much uncompressed data, per-file size caps) and unsafe entry paths (absolute
paths or
..traversal), and never overwrites existing files (stored under generated ids). The importer also reads attachments fromcard.attachments(newer Trello exports), not only from the action log, and uses the correct Meteor-Files insert API (the previous calls were no-ops on Meteor 3). Single board imports (the .json file or the pasted JSON, after the map-members step) now run through the same server-side HTTP path rather than the realtimeimportBoardmethod, so a heavy import can no longer drop the WebSocket and get retried in an endless loop (the page flickering with “Invalid frame header” / repeated “logged out” errors). When importing only a single board .json and you have saved Trello API key and token, WeKan uses them on the server to download that board’s attachments, background image, member avatars and card stickers from Trello (a .json export often omits stickers; avatars only fill in mapped users who have none — an existing avatar is never overwritten); each download is best-effort and a failure never aborts the import. After a single-board import the new board’s data is subscribed and loaded before opening it, so it shows its swimlanes, lists and cards immediately instead of needing a browser page reload (the HTTP import, unlike the old realtime method, does not push the written documents to the client by itself). - Import Trello-only card features: stickers (shown as Font Awesome icons on minicards and the card detail), card cover (color or attachment), card location (name, address, coordinates with an OpenStreetMap link), and the due-date “complete” checkbox shown on the minicard. Trello’s two named sticker packs are renamed and highlighted (the icon keeps its normal colour) so they stay distinct: the “taco” pack becomes “mascot” with an underlined icon, and the “pete” pack becomes “computer” with a ring around the icon, e.g. “pete-ghost” imports as “computer ghost” with a Snapchat-ghost icon. Several named stickers that used to share an icon now get their own Font Awesome 4.7 icon (mascot active => heartbeat, pixel => qrcode, proto => flask, embarrassed => meh-o, clean => bath, computer shipped => truck).
- Live Trello API import: paste your Trello API key and token on the Trello
import page to list all your Trello workspaces and boards, then import all
or selected boards together with their attachments (downloaded
server-side). Imported boards are placed under a personal workspace named
after their Trello workspace, created by name if it does not exist, under an
optional parent workspace you choose. The API client respects Trello’s rate
limits: it spaces out requests, honours
Retry-Afteron HTTP 429, retries transient 5xx and network errors with capped exponential backoff, and reports a clear error on an invalid key/token (401). After a successful API import you are taken to the All Boards page where the new boards appear. - The live API import runs as a background job on the server: you can navigate away and come back to the Trello import page to watch progress, see per-board results, and read the full error log. Errors are shown in a selectable text box with a one-click “Copy to clipboard” button (and you can still select and copy just part of the text) so they are easy to share when fixing issues. If the import stops on a fatal API error (invalid token, or rate limit still failing after retries) you can fix the cause and Resume from where it left off, and a server restart leaves the job paused for resuming rather than lost. You can also Cancel the import, or Cancel and delete the boards already imported, to start the whole process over cleanly.
- You can optionally save your Trello API key and token with the Save and Delete buttons on the import page. When saved, they are stored only on the server, never sent back to the browser, and are reused automatically when you list workspaces or import (so you do not have to paste them again); a “saved” indicator is shown, Save can overwrite them with new values, and Delete clears them from the database. If you do not save them, they are kept only in server memory for the running import and re-supplied when you resume.
- Larger Trello JSON exports can be selected as a file instead of pasted.
- Keep imported usernames for later mapping. Imported members that match an existing WeKan user (by username, or by a previously recorded imported username) are mapped automatically, and the imported username is remembered on that user so future imports map too. Members with no matching WeKan user are no longer lost: their usernames are kept on the board, so an admin can map them to real users later in Admin Panel / People (Imported Usernames), without having to map everyone up front at import time. Thanks to xet7 and Claude.
- Attachments now import. Trello attachment URLs require OAuth to download, so
WeKan could not fetch them. The Trello import page now has two separate file
fields: a .json field for a single Trello board, and a
.zip field for a package produced by the
Trello Card Attachments Downloader.
The .zip may contain one or more board .json files together with each
board’s attachments in a board-name subfolder. The .zip is uploaded over HTTP
and processed entirely on the server (the attachment bytes never travel over
the realtime WebSocket, which previously overflowed the connection and made
the page flicker): WeKan detects every board .json, matches each board to its
attachment subfolder by name, streams each file straight into the Default
file storage, imports all boards, then opens All Boards. The upload is guarded
against abuse — it rejects oversized uploads, zip bombs (too many files or too
much uncompressed data, per-file size caps) and unsafe entry paths (absolute
paths or
- Board background images can now be stored in WeKan. A new
backgroundsfile storage directory is created alongsideattachmentsandavatars(using the current default storage backend), and Board menu → Board backgrounds lets a board admin upload background images, set one as the active board background, download, and delete them. Board export now includes the board’s background images and re-imports them, and a Trello board’s background image is downloaded and stored on import (so it keeps working even if the original Trello URL later changes). Thanks to xet7 and Claude. - Stickers can be added to and removed from cards directly in WeKan, chosen from a set of Font Awesome icons similar to Trello’s stickers (previously stickers only arrived via Trello import). The picker also includes every “mascot” (underlined) and “computer” (ringed) highlighted sticker that a Trello import can produce — generated from the same icon mapping the importer uses — so any imported sticker can also be added by hand. Stickers show on the minicard and in the card detail. Thanks to xet7 and Claude.
- The Trello-style “complete” checkbox (mark a card complete/incomplete, independent of the due date) is shown as an animated green checkbox to the left of the card title, both on the minicard and in the opened card, with “Mark as complete” / “Mark as incomplete” tooltips. It uses the same animated checkbox style as Admin Panel / Settings / Announcements and is vertically centered with the title text, and the two stay in sync. The minicard and the opened-card checkboxes use the same checked style (the board theme’s colour, or green when no theme is set), so they always look identical. Subtask checkboxes and the card-detail custom-field checkbox now use the same animated checkbox as checklist items (they previously used static square icons), so every checkbox on a card animates consistently. Thanks to xet7 and Claude.
- Cards can now have multiple locations, similar to multiple members. The card
detail shows a Location section (after Labels and Stickers) listing each
location with its name, address and an OpenStreetMap link, with an “Add
location” button to add more and a button to edit or remove each one. A single
location imported from Trello keeps working and is shown in the same list. The
Add/Edit location popup can also detect a location from any map link (Google
Maps, OpenStreetMap, Bing Maps, Apple Maps, or generic
?q=/?ll=links): paste the link, press “Detect”, and the latitude, longitude and (when present) the place name/address are filled in automatically. The popup also has an “Open map links at” setting (OpenStreetMap by default, or Google/Bing/Apple Maps) saved to the user profile, controlling which map service the location “Open in map” links use. Thanks to xet7 and Claude. - The opened card now docks to the top of the window, overlaying the global and
board header bars, instead of opening downward from the clicked minicard, and
it can be dragged all the way to the top without its top hiding behind those
bars. (At 100% zoom the board wrapper no longer sets a
transform: scale(1), which had made it the containing block for the fixed card and trapped it below the headers.) Thanks to xet7 and Claude.
and fixes the following bugs:
- Fix Wrong card number after Import. Thanks to titver968, xet7 and Claude.
- Fix Board Export/Import error.
Fix import/clone of inconsistent board JSON so the newest WeKan can import
board exports from any newer or older WeKan version. A syntactically valid
export can still be internally inconsistent (a board member whose user
account was deleted is no longer in the export’s
users, cards pointing at a missinglistId, orphaned checklists, or a missinglistsarray). Such exports previously failed import as “error-json-malformed” or silently dropped data (cards with an undefined list never rendered). The importer now skips dangling user references in the member mapper (clientwekanMembersMapper, serverwekanmapperused by board cloning, andWekanCreator), falls back to the first imported list — creating one default list when the export has none — for cards with a danglinglistId, and skips orphaned checklists whose card is missing. The importer remains version-agnostic: it never reads_format, normalizes oldidvs_idfields, and ignores the sourceboardId. Addedtests/wekanCreator.inconsistent.test.jscovering these cases. Thanks to titver968, xet7 and Claude. - Fix Trello import returning HTTP 500 on any card that has an attachment. A
past refactor removed the
linksvariable declaration but left its consumer inmodels/trelloCreator.js, so importing an attachment card threw “ReferenceError: links is not defined”. Also fixed a strayreturnthat silently aborted importing the rest of the cards when one attachment URL was blocked (nowcontinue), and Trello cards no longer all import as card number #0 (the Trello short numberidShortis preserved). Thanks to xet7 and Claude. - Fix attachments not importing from WeKan board JSON exports. The importer
called the old Meteor-Files
Attachments.load/insert(..., cb, true)API, which is a no-op on Meteor 3, so exported base64 attachments were silently dropped. It now inserts them withAttachments.insertAsync, and one failed attachment no longer aborts importing the rest of the cards. Thanks to xet7 and Claude.
