30802.1.0

This release supports server version 3.8.2. This release is our first official public release.

Package changes:

  • Removed stale array and data-default dependencies
  • Increased lower bound on base dependency to 4.8 to relect our GHC testing.

Improvements:

  • Subprocess error logs are now only created on demand. Previously we created them on startup before any subprocess errors had occurred.
  • We now provide a QuickCheck test for some infrastructure.

Bug fixes:

  • Fixed a bug whereby some resize operations would cause a program crash by triggering an unsafe mutable vector operation in Vty.
  • New user creation is now handled successfully and no longer requires a client restart to function reliably. Previously bad behavior included not coloring new users' names and not showing new users' names at all on their messages.
  • Message selection mode is no longer blocked by errors and other non-post content.
  • Subprocesses that fail to run are now consistently mentioned in the subprocess error log.

30802.0.0

This release supports server version 3.8.2.

Package changes:

  • Relax constraint on containers to allow 0.5.7 or greater.
  • Upgraded mattermost-api to 30802.0.0.

Bug fixes:

  • The help interface now updates properly when showing either the main help window or the scripts help window.
  • Attachments are now saved asynchronously.
  • Attachments are now opened without using the browser, thus removing our dependency on a valid browser session with the server (fixes #128)
  • Editing state is now saved before switching history entries (fixes #210)
  • Messages with unknown authors trigger a user metadata fetch (fixes #205)

New keybindings:

  • C-o now opens the URL list while scrolling through channel messages.
  • C-c now cancels channel selection in C-g mode

UI changes:

  • Channel scroll mode keybindings were added to the help page.
  • We no longer perform string highlighting on the contents of Markdown code spans in messages.
  • On startup, only the scrollback for Town Square is fetched to improve performance. Scrollback for other channels is fetched on demand.
  • We now use the channel sigil "~" rather than "#" to match the web client behavior, and highlight ~-prefixed channel names (fixes #204).

30701.0.0

This release supports server version 3.7.1.

New features:

  • Matterhorn now has basic support for 3.7's new "group channel" feature. If other users add you to a group channel, it will appear in the sidebar with the member usernames listed (e.g. "#bob, sue, ..."). Creation of group channels will be supported in a future release.
  • When the urlOpenCommand program produces output on standard output or standard error, this output is now logged and a message is posted in the current channel with the path to the log file. This feature prevents the URL open command from poisoning the terminal state with unexpected output.
  • Added a /members command to show current channel membership.
  • Channel header changes from other users will now cause the channel topic string to update.
  • Added a /delete-channel command to delete the current channel.
  • Markdown rendering now puts empty lines between adjacent block elements of the same variety to improve readability.

Bug fixes:

  • Message selection now only supports reply/edit/delete on normal posts (fixes #174)
  • C-n/p now only change channels when a non-DM channel is selected (fixes #82)
  • We now handle new user events (fixed #111)
  • On channel change we now always reset the channel list to scroll to the top (fixes #138)
  • When a draft message is left in the editor when changing channels, a new sigil ("»") appears for the previous channel instead of the usual "#" to indicate this.
  • The help interface now resizes properly all the time.

Performance improvements:

  • On startup, all channel contents are fetched asynchronously. Town Square fetches are prioritized. These changes drastically improve startup time, even on fast connections.

Documentation changes:

  • The README now includes a feature list, a brief feature overview for new users, and a section on how to contribute.

Package changes:

  • Upgraded mattermost-api to 30701.0.0.
  • Binary releases now include the copyright and licensing information for all dependencies.

Internal changes:

  • Added preemption support for asynchronous work queue processing. doAsync(With) now both take an AsyncPriority.

30600.2.4

New editing keybindings:

  • C-w, M-Backspace now delete the word to the left of the cursor.

  • M-d deletes the word to the right of the cursor.

  • C-k now kills text from the cursor to the end of the line and copies to an internal buffer; C-y pastes from said buffer.

  • C-b, C-f move back and forward by one word, respectively.

  • Many editing keybindings are now present in their own Help page section.

Package changes:

  • Upgraded text-zipper to 0.10.
  • Upgraded mattermost-api to 30600.2.2.

30600.2.3

Bug fixes:

  • Message-yanking failures due to missing programs (e.g. xclip) no longer trigger an unhandled exception (fixes #170)
  • Users that are not members of the current team are now hidden from the user list (fixes #161)
  • User statuses in the sidebar are now periodically refreshed
  • Supported server commands now appear on the help screen (fixes #162)
  • Files containing non-UTF-8 content no longer trigger unhandled exceptions when being read by matterhorn (fixes #168)
  • Updated repository URL in error message about reporting problems (thanks @tommd)

30600.2.2

  • Improved formatting of message attachments so that their filenames are shown. Previously only their hash identifiers were displayed. This change also entails asynchronous fetching of attachment metadata.
  • Upgraded to mattermost-api 30600.2.1.

30600.2.1

  • Fixed a bug that caused message selection mode to trigger a Vty crash when a message being rendered was larger than half of the area available for the message list.

30600.2.0

  • Added a new message selection mode. This mode provides access to four new features: replies, edits, deletion, and verbatim text yanking. To enter this mode, use the default binding of C-s (and cancel with Esc). The resulting cursor can be used to select messages in the current channel and perform the following actions on them:

    • y: for messages with any verbatim text, yank the verbatim text to the first verbatim block in the message to the system clipboard (works on Linux and OSX)
    • r: reply to the selected message. To cancel a reply, press C-c or Esc.
    • e: for messages written by the current user, edit the selected message. To cancel an edit, press C-c or Esc.
    • d: for messages written by the current user, delete the selected message (with a confirmation).
    • o: for messages containing URLs, open all URLs in the selected message.
    • j/k/up/down/pgup/pgdown: change the selected message cursor position.

  • Added a C-r binding to begin a reply to the most recently posted message in the current channel.

  • M-e now toggles multiline editing mode rather than just enabling it. Previously, Esc toggled it off.

  • Upgraded to mattermost-api 30600.2.0.

30600.1.0

  • Upgraded to mattermost-api 30600.1.0. This fixed /me and /shrug server-side command execution failures.

30600.0.0

Initial versioned release for server verison 3.6.0.
