Added

• Chat: confidential messages in direct messages (e.g. for a password), end-to-end encrypted in both browsers, relayed live and never stored by the server, shown to the recipient only once.
• Chat
  • Chat rooms (menu Common → Chat): anybody creates a room and chooses its participants, users and groups; members who join a group later take part at once. The creator and the moderators edit and delete the room. Rooms are visible to their participants only, administrators included.
  • Direct messages: anybody can write privately to any user shown in the user selection, from the chat page, from a user found in the menu search (start chat / send file; for everybody, with the users of the user selection) or by clicking an author in any conversation; whoever got a message can answer. Only the two read the conversation, administrators neither.
  • Messages with formatting (text colours, lists, links, inline code and code blocks of several lines), files of any type (paste, drag & drop or file dialog; images as thumbnails), emoji reactions and replies as threads of their own, which can be followed. The files are stored in the data transfer: in an area per room, whose participants see it in the data transfer and where the files are kept as long as chosen in the room; files of direct messages go into the personal box of the recipient. Without the data transfer plugin, no files are exchanged. Own messages can be edited and deleted, moderators hide messages with a reason and see the history of a message.
  • Typing @ suggests the participants of the room; a mentioned person is notified at once, in the app and by mail. New messages are notified once per room until read, by mail only if not seen in the app within an hour; rooms can be muted.
  • New messages appear without reload (server-sent events, with polling as fallback). Behind a reverse proxy, the chat needs an unbuffered connection, see the administration guide.
• Chat: a file of a message can also be opened in its data transfer area, besides downloading it.
• Chat: a message can be marked unread, threads with unread replies are marked, and in a thread a line shows the first unread reply.

Improved

• Search and selection boxes ignore accents and German umlaut spellings: "Andre" finds "André", "Mueller" and "Muller" find "Müller", "Strasse" finds "Straße", and vice versa. Applies to entries indexed after the update, i.e. completely after the next nightly re-index.
• Admin guide: the backup script compresses the dump of the files (about half the size), because pg_dump writes their contents hex encoded.

Fixed

• Outgoing invoices: invoices saved in the new interface were not found by the name of their customer until the next search index rebuild.
• JIRA links: an issue key needs at least two leading uppercase letters, so a postal code like "D-34286" in a text is no longer linked as an issue.
• Project selection: projects are also found by their number (e.g. 7.002) and by the name of their customer.
• Scripts: showing the log of a running script could fail with an error.
• Time sheet list: the filter including all sub structure elements could not be switched off. It is replaced by the filter "without structure sub elements", off by default.
• The order and invoice caches no longer refresh each other endlessly (e.g. during the daily order book snapshots) when an invoice refers to a deleted order position.
• Search in the main menu: deactivated users are no longer found (they still are in the user list).
