From the project's README.

Source code

• Pinned certificate: the connect form shows the full SHA-256 fingerprint; an ⓧ button forgets it.

• Connect errors: a server address that can't be resolved is reported as such, not as an untrusted certificate (heidrun-protocol 1.1.3).

• Bookmark shortcuts: assign ⌃⌘1–⌃⌘9 to a bookmark to open it from the Bookmarks menu; applies immediately and shows in the bookmark sidebar.
• Quit prompt auto-quits: an unanswered quit confirmation quits after a countdown (default 30 s, Settings → Connection) and is skipped on logout, restart or shutdown.

Downloads

• News remembers Board or Threaded per server across reconnects and bookmark autoconnects.
• The Connection menu no longer goes inactive after switching the news view.

Downloads

• Heidrun-1.7.1-234.dmg  (8.4 MB)

• News auto-download: threaded servers load board and threaded news on first open and show the one with content (threaded when both have content); progress and Cancel in the Task Manager.
• Settings → News: turn auto-download off and pick the default news view (Automatic, Threaded or Board).

• Softer sound effects: the classic sounds are denoised, filtered, faded and level-matched.
• ⌥⌘W closes all other windows and tabs (File → Close Others), also ones showing the server agreement.
• Disconnect closes the window while other connections stay open; only the last one returns to the connection form.

Downloads

• Heidrun-1.7.0-232.dmg  (8.4 MB)

• Per-sound switches: turn each sound effect on or off in Settings → Sounds.
• Board/Threaded switch in News: threaded servers also show their plain news board, as in classic Heidrun.

• The plain news input is a fixed, smaller height.
• The Connecting screen shows the New Connection and Task Manager toolbar buttons.

• The message input in Messages no longer touches the transcript divider; Chat uses the same gap.
• Closing a reopened connection no longer asks to save an “Untitled” document.
• Reopening connections at launch no longer leaves an extra tab stuck on “Connecting…”.
• Reopened connections open as tabs, even while Touch ID is waiting.

Downloads

• Heidrun-1.6.4-221.dmg  (8.1 MB)

• Back and forward in threaded news: two-finger swipe, mouse side buttons, ⌘[ / ⌘] or the new arrows.
• New Connection button in the toolbar opens another connection window.

• The Task Manager toolbar button has a simpler arrows icon.
• New Connection uses the same icon in the toolbar and the Task Manager.

Downloads

• Heidrun-1.6.3-208.dmg  (8.1 MB)

• Quick Look shows images: PNG, JPEG, GIF, TIFF, HEIC, WebP and more.
• Upload into a drop box from its context menu, or select it and click Upload….
• A close button hides the transfer box under the file list without clearing the Task Manager.

• Space bar closes Quick Look again when it already shows the selected file.

Downloads

• Heidrun-1.6.2-199.dmg  (8.0 MB)

• Opening a folder briefly showed the previous folder's files until the new listing arrived.
• The sidebar selection turns grey while Heidrun is in the background, like other Mac sidebars.

Downloads

• Heidrun-1.6.1-191.dmg  (8.0 MB)

• Back and forward in Files. Swipe with two fingers (the page slides like Safari), use the mouse side buttons, ⌘[ / ⌘] or the new ‹ › buttons; ⌘↑ goes up. Revisited folders appear instantly, with their selection and scroll position.

• The sidebar marks the open feature with an accent-coloured pill.
• The Files column header has a single full-width divider line.

Downloads

• Heidrun-1.6.0-186.dmg  (8.0 MB)

• Protocol Console: Export… saves the shown transcript as a log file.

• Uploads to classic Hotline servers stalled at 0 bytes. The client sent the transfer handshake twice; it now sends it once, as the original Heidrun did.
