Security issue fixed :

  - CVE-2017-15923: Fixed a crash in parsing IRC color
    formatting codes (boo#1068097).

Bug fixes :

  - Update to version 1.7.4 :

  - Fixed a bug causing the size of a custom chat text view
    font set via the configuration dialog to be ignored. A
    font size modification done via the Enlarge/Decrease
    Font Size actions is now applied on top of the
    configured size (or the system default font size,
    respectively).

  - Update to 1.7.3 :

  - Added a copy action to the context menu of nicknames in
    the chat text view.

  - Re-enabled channel mode buttons.

  - Reduced emission of Unicode directional control
    characters in the chat text view. Unnecessary control
    characters could sometimes cause problems with copying
    text from Konversation and pasting it into terminal
    applications, confusing them.

  - Fixed handling of nick and channel prefix characters
    potentially using the same set of symbols.

  - Removed redundant escaping of angle brackets in GECOS
    ('realname') field.

  - The nickname combobox will no longer change the nickname
    to the current value whenvever it loses focus.

  - Fixed color scheme handling in the treelist version on
    the tab bar, fixing an issue where the background and
    text color of the selected item would sometimes be the
    same, rendering the item unreadable.

  - Fixed handling of IRC URLs for channels starting with
    more than one #, addressing a percent-encoding problem
    with bookmarks of them.

  - Fixed custom chat text view font family reverting to
    system default font family upon using the
    increase/decrease font size actions.

  - Fixed chat text view font size adjusted via the
    increase/decrease font size actions reverting to
    configuration default when OK'ing the config dialog.

  - Fixed incorrect checkbox states in the Channel Invite
    dialog.

  - Fixed a crash in IRC v3 extended-join parsing.

  - Fixed a crash in parsing IRC color formatting codes.

  - Fixed a minor memory leak in the Join Channel dialog
    code.

  - Removed unnecessary nickname list debug message sent as
    warning.

  - Trim description from redundant phrasing, and ensure
    neutrality."
