v0.1.0

First release. Google-Docs style co-editing of issues, comments and wiki pages with no extra infrastructure: browsers synchronize through Redmine itself over HTTP polling, no websocket server.

Features

• Collaborative real-time editing (Yjs CRDT) of issue descriptions, issue notes, edited journal notes and wiki pages
• Transport over plain HTTP polling to the Redmine app itself, optional long polling; no websocket server or infrastructure change
• Every other field of the issue edit form (status, assignee, dates, custom fields...) is shared as well: remote changes are applied to the native controls with a "changed by" mark, and survive Redmine's own form refresh
• Remote carets and selections of the other editors drawn over the textarea, one colour per user with a name label
• Presence bar under each shared textarea: who else is editing, who is typing, live/offline state
• Shared drafts survive a page reload for a configurable time and are discarded after everybody leaves
• Saving from a co-edited issue form or wiki page does not trigger Redmine's stale-object conflict for the other editors; changes made outside a collaborative form still do
• New comments private (default, presence only) or shared; when a shared comment is posted the other editors get a banner naming the author and the notes box is locked until they reload
• Plugin settings: fields to share, notes mode, poll periods, long polling hold, draft lifetime, compaction threshold

Compatibility

Redmine 5.1, 6.0, 6.1 and 7.0 (tested in CI). No Node.js needed to install: the Yjs bundle is committed.
