v10.21 2026-07-22 WeKan ® release

This release adds the following features:

• Card links keep working after the card is moved to another board. A card URL is /b/:boardId/:slug/:cardId; after moving the card the link opened the old board and found nothing. The card route now resolves the card's CURRENT board via the permission-checked card publication and, if it differs, redirects there — so a link stays valid across board moves as long as the viewer has access to the destination board (like Trello). If the user cannot see the card's new board, the URL's board is kept; a redirect loop / stale navigation is guarded against (#4758). Thanks to Robdebert and xet7.

and fixes the following bugs:

• Copy-code-block button in the card viewer is now reliable. It previously ran once with a global query, so it decorated only whichever code blocks were on the page at that instant ("works sporadically"), was lost after editing, and copied the HTML-escaped inner markup (wrong content). It is now added per viewer in Template.viewer.onRendered (so every description / checklist item / comment gets it and it is restored on re-render), de-duplicated, copies the RAW code text via the async Clipboard API (with a fallback), and the button title is translated (#5149) (github.com). Thanks to C0rn3j and xet7.

Thanks to above GitHub users for their contributions and translators for their translations.
