Added

• Per-MIME clipboard size limits and OOM protection via clipboard_mime_size_limit
  config option and COPYQ_CLIPBOARD_MIME_SIZE_LIMIT environment variable. For
  example text/html.*:0;.*:100M disables storing HTML and sets 100MiB max
  size for all other formats (this size limit is the default: .*:100M).

• AppImage support (WITH_APPIMAGE CMake build option).

Fixed

• Fixed thumbnails hidden for tagged image items if "Show simple items" option
  is enabled (#3602).

• Fixed window invisible in remote desktop sessions (#3593, #3582, #3400).

• Fixed null characters in concatenated selected items breaking paste in
  other applications.

• Handle possible file operation errors and locks when synchronizing items to
  files on disk and shared storage (#3368, #3579).

• Avoids potential crash on fetching very large data in clipboard.

• Wayland: Fixed portal shortcuts handling in non-default app sessions.

• Wayland: Fixed main window shown on startup with tray disabled on wlroots
  compositors (#3567).

Added

• CSS properties for pinned/notes indicator color and width. See
  Plugin Indicators.

  ItemPinned { qproperty-pinnedIndicatorColor: rgba(0, 0, 255, 128); }
  ItemPinned[CopyQ_selected="true"] {
    qproperty-pinnedIndicatorColor: rgba(255, 204, 0, 255);
  }
  ItemNotes { qproperty-notesIndicatorColor: rgba(100, 200, 100, 180); }
  ItemNotes { qproperty-notesIndicatorWidth: 24; }

Changed

• "Show under mouse cursor" shortcut now hides the window if it is already
  visible (#2272).

• Updated icon font to Font Awesome 7.2.0.

• Dropped private Qt header usage (replaced with public QNativeInterface API).

  Note for packagers: The application no longer links against private Qt
  headers, so it does not need to be rebuilt on Qt minor version updates.

• Dropped support for unmaintained Qt 5 version of the app.

• Improved performance of scripts.

Fixed

• Fixed blank items appearing in search results.

• Fixed rounded item corners showing wrong background color.

• Fixed item background rendering on some systems and themes (#3495).

  client processes.

• Windows: Excludes unnecessary test executable and some libraries from
  installer and portable zip.

Added

• Tab encryption support. Allows encrypting all tab data on disk using a single
  custom password. Common keychain software to store the password can be also
  enabled with password expiration (locking tabs).

  Note for packagers: This requires QCA and QtKeychain libraries, but it can be
  disabled at build time with CMake options WITH_QCA_ENCRYPTION and
  WITH_KEYCHAIN (#2617).

• Audio playback via playSound() script function for playing WAV, MP3 and
  FLAC files.

  Note for packagers: This requires miniaudio library, but it can be disabled
  at build time with CMake option WITH_AUDIO.

• New script function stats() for gathering runtime statistics (memory usage,
  UI elements, tab state, loaded plugins, running actions).

• Nord themes. Thanks to @ArtyomBabiy.

• Theme is applied to the About dialog (#3296).

• Log directory can be changed using COPYQ_LOG_DIR environment variable
  (if COPYQ_LOG_FILE is not used).

  slowdowns (#3340).

• ItemSelection() and selectItems() preserve the original selection
  order (#3271).

• "Show the tray menu" command is excluded from the tray menu (#3353).

• Fixes potential data loss on partial tab rename failure during drag-and-drop.

• Fixes drag-and-drop expanding collapsed tab groups.

• Fixes window becoming invisible when started minimized (#3440).

Fixed

• Fixes saving edited HTML and setting style in internal editor (#3227).

• Fixes updating selected item colors (#3219).

• Wayland: Fixes clipboard access in KDE Plasma 6.5 (#3228). This requires
  KGuiAddons library installed on the system.

Fixed

• X11: Fixes registering global shortcuts with modifiers (#3212).

• macOS: Fixes providing builds for Intel architecture.

• Fixes maximum length for session name (it is 16 characters as the error
  message says, not 15).

Added

• Wayland: Global shortcuts are now registered using Portal if available.

• Black theme (#3142). Thanks to @FadeMind.

• Adds attributes for controlling the dialog window created via dialog()
  (#2947): .onTop makes the dialog stay on top of other windows, .modal
  makes the dialog modal (blocks interaction with other windows in the
  application until closed).

• Adds support showing icon font symbol in notes using
  application/x-copyq-item-icon format.

• Adds support for setting colors in theme files by name. For example:
  edit_bg=white.

Changed

• Temporary tabs that are not stored on disk will now not expire if
  configuration changes (#3172).

• Pinned and locked items will not be dropped if tab size (maximum item count)
  changes (#3008).

• The app now propagates exit code properly if it is aborted or receives a
  Unix signal (SIGINT, SIGTERM).

• Support for Qt older than 5.15 has been dropped.

• The build now uses Qt 6 by default. Use cmake -DWITH_QT6=OFF ... to build
  the app for Qt 5.

• Windows: The application will be now hidden from screenshots and screen
  recordings by default (#3165). This can be disabled using option "Hide from
  screenshots and recordings".

• Logs are now stored in multiple files based on the process and the log
  records have a slightly different format (start with timestamp).

Fixes

• Drops unsafe sanitizing QTextDocument fonts (#3156). Qt 6 should handle any
  rich texts safely now.

• Logging now does not use lock files and avoids crashes if the application
  loop was not yet started.

• Avoids resetting properties of a tab if it is renamed.

• Fixes setting color for item counter (#2717).

• Fixes editing and providing UTF-8 text by default (#3093).

• Avoids collapsing tab in the tab tree after it is moved.

• Fixes item counter value after moving the tab in the tab tree.

• Fixes moving tab group with items in the tab tree.

• Linux: Fixes storing the first clipboard change after starting the app and
  modifying configuration.

• Linux: Avoids exiting on commit data request from the session manager (#3145).

Added

• Adds support for dark/light window title scheme.

• New frameless_window option (#2570) toggles the main window frame and title
  bar (if supported by the window manager):

  copyq toggleConfig frameless_window
  

• Adds support for localizing command names in the command INI files (#3032):

  [Command]
  Name = ...
  Name_cs = ...
  Name_fr = ...
  Name_pt_BR = ...
  Name_pt = ...
  

• Adds support for showing preview for more image formats
  (namely ico and webp).

• Adds support for more complex network requests in scripts. New
  NetworkRequest class can be used to set custom headers, HTTP method, number
  of allowed redirects and timeout.

Changed

• Avoids hiding the main window on backspace (#3107).

• Enables Vi/Emacs navigation (#3012) in menus, and Ctrl+[ in Vi and Ctrl+G
  in Emacs to work in many other places as Esc key (for example, to hide menus,
  dialogs). Users can override shortcuts, but not some reserved ones in
  specific cases (mainly, if the item list or a menu has focus).

• Selections and current items/rows/data in scripts now only relate to the
  tab selected with tab(...) in scripts (this is still by default the
  selected tab when the command started). Affected script functions:

  • move()
  • setData()
  • removeData()
  • selectedItems()
  • selectedItemData()
  • setSelectedItemData()
  • setSelectedItemsData()
  • currentItem()
  • ItemSelection().current()

• Drops unnecessary timeouts when executing commands and actions from scripts.

• Avoids fetching and passing clipboard to action()/execute() if the
  commands do not contains %1 placeholder. This can improve performance.

Added

• Emacs navigation key-bindings support.

• Adds support for setting urgency and persistency to notifications. Script
  function notification() takes new arguments: '.urgency' (low, normal, high,
  critical), '.persistent' (toggle persistent notification)

Changed

• Updates icon font from Font-Awesome 6.7.2.

• On Windows, the main window is shown when starting the application using
  the program icon (#2965).

• Calling exit() script function prints "Terminating server" on stderr
  instead of stdout.

Fixed

• Fixes item selection with Ctrl+Space (#2850).

• Fixes confirming exit if any commands are running.

• Fixes selecting specific row on search (#2770).

• Clipboard data cloning will be now aborted if the data changes during the
  process. This avoids using incomplete data in rare cases.

• Fixes contrast of the selected row number color (#2887). The row number text
  color of selected item is set to the same color as item text by default. This
  can be overridden via "Edit Theme" button using option num_sel_fg.

• Fixes internal editor syntax highlighting for numbers containing separators
  (for example 100_000, 0x1234_abcd) and avoids incorrectly highlighting
  multiple lines as regular expression in some cases.

• On GNOME (Wayland session), the clipboard monitor and provider processes run
  in XWayland mode because GNOME does not support Wayland data control
  protocol. This behavior can be skipped by settings QT_QPA_PLATFORM
  environment variable to "wayland" (or other value).

• On Wayland compositors, fixes unnecessary application start delay if
  clipboard access (the data control protocol) is not supported.

• On Linux, the "Ignore items with no or single character" predefined command
  properly avoids synchronizing empty text or single character.

• On Linux, fixes waiting on keyboard modifiers release when synchronizing
  selection.

• Avoids recursive item preview updates when using display commands.

• Avoids removing items if drag'n'drop action fails.

• Wayland: Fixes crash if getting owned clipboard data.

• Wayland: Fixes setting UTF-8 text on broken GNOME's XWayland.

Added

• Allows processing all clipboard changes (#2787, #2746).
  If clipboard contains secret (for example, copied from a password manager),
  onSecretClipboardChanged() script function is called with data containing
  mimeSecret format set to 1. Also ensures that callbacks are called
  consistently for all clipboard changes with properly set formats
  mimeClipboardMode, mimeOutputTab and mimeCurrentTab.

Fixed

• Fixes editing multiple items (#2810).

• Fixes synchronization plugin causing redundant UI updates and menu
  misbehavior (#2649).

• Fixes showing sub-menus for custom commands in tray menu (#2730).

• Fixes switching tab if onItemsLoaded() is overridden (#2788).

• Fixes theme option hover_item_css (#2687).

• Avoids modifying data from display commands and causing redundant UI updates
  (#2837).

• Avoids sharing execute() state in case it is launched recursively.

Added

• Adds editItem() script function for editing any item format (#2672).

• Item color is now shown in tray menu as the default icon (#2700).

Changed

• Removes large margins in the tab tree.

• Single action "Toggle Tag …" replaces the two separate actions "Tag as …" and
  "Remove tag …" for each custom tag (this can make the item context menu a lot
  more compact).

• Selected items can now be accessed even from commands started from outside
  the app using global commands or from command line.

• The dialog() script function can now be used for asking Yes/No questions
  without providing any fields. In such case, the function will return true
  instead of undefined after accepting the dialog. For example:

  const remove = dialog(
    '.title', 'Remove Items',
    '.label', 'Do you really want to remove all items?'
  );
  
  if (!remove)
      abort();
  
  // remove items ...
  

• The execute() script function now throws an exception when command cannot
  be executed instead of returning undefine.

Fixed

• Includes many performance improvements for working with large amount of items.

• Fixes triggering menu items by number (#2569).

• Fixes text color in the internal item editor (#2643).

• Fixes showing global shortcuts in tray menu (#2382).

• Fixes passing captured texts to automated commands (#2707).

• Fixes duplicate synchronized items after tagging or modifying data.

• Fixes situation when display commands stop updating items.

• The pre-defined "Move to tab" action will be shown only if the current tab is
  not the same as target tab (#2669). Previously, in such case the item was
  removed unexpectedly.

• Windows: Detect and ignore secrets from more apps (#2679).

• Linux: Fixes storing previously synchronized clipboard (#2630).

• Linux: Fixes storing selection when "Store text selected using mouse" option
  is enabled but "Run automatic commands on selection" is disabled (#2651).

• Linux: Fixes clipboard synchronization with Qt 6 GUI framework.

• Linux: Fixes showing tab tree labels with Qt 6 GUI framework.
