Plasma/5.1 Changes

Artwork and Visuals

• Icons (added tons of icons to the Breeze theme,
• Refined plus Systray icons to match the general theme
• Native Breeze widget themes for Qt4 and Qt5
• New Look & feel / Megathemes system settings module
• Plasmoid alternatives switcher
• New clipboard Plasmoid
• System load viewer Plasmoid
• Human Interface Guidelines (HIG) restructuring to improve usability
• Visual glitch fixes

Workspace Elements

• kdeplasma-addons returns, with many widgets: notes, fuzzy clock, timer, system load viewer, icon tasks
• Time zone support in Digital Clock
• Many more runners thanks to kdeplasma-addons being back
• plasma windowed, a method to run Plasmoids as applications, useful for example for Plasma Media Center
• Notifications and running job display has been polished
• Calendar renders much faster and more memory-efficient
• Date display in the clock
• Logout and Lock screens now supports keyboard navigation

Folder

• Significantly improved performance and memory usage in desktop mode.
• Faster, more responsive drag-and-drop operations.
• Greatly expanded context menus.
• Support for the 'associated application' system is back.
• Keyboard navigation improvements (support for Home and End keys, etc.).
• Spatial keyboard navigation (arrow keys, etc.) for unsorted views.
• Tooltips can be disabled.
• Icon size can be changed.
• Better guard against corrupt configuration.
• Many bug fixes (a few bigger ones: graphical glitches with drag and drop on some

drivers addressed, sort by size was broken, anchored range selections on unsorted views misbehaved, drag-onto-to-launch for view-internal drag and drop crashed didn't work, ...).

• Bug due to which the view context menu now works when Folder is a panel popup fixed.

Kicker Application Menu

• Basic support for editing menu entries right from the context menu (name, icon, command, etc.).
• Per-instance hiding of menu items.
• Basic integration with Muon Discover / package managers via PackageKit-Qt (you can jump into them via the context menu).
• Support for screen readers and other a11y software.
• Various bug fixes (a few bigger ones: improved positioning, "Add to Panel" with multiple applet instances in different panels could pick the wrong panel, initial keyboard focus when invoked via shortcut wasn't on the search field, ...).

Task Managers

• Icons-only Task Manager ("Icontasks") is back.
• Improved lifecycle behavior for launchers and startup notifications (clean handoffs/replacing, less visually messy co-existence).
• More reliable identity mapping between startup notifications and launchers and windows.

Baloo Search

• A user-visible query language which can be accessed via the kioslave. Example - `baloosearch://?query=tag:Fire`. The query language can handle quite complex expressions. This will create a "magic folder" which will be updated in realtime
• Better UTF-8 handling in Searching - We now take diacritic marks into account. See this blog post
• Removable Media Storage - We now never index Network File Systems.
• Better detection of frequently modified files. We delay indexing for them.
• Detecting xattr changes - Baloo is now more of a file indexer and will listen to changes on xattr for files. This means any application can set the tags/ratings by just setting the xattr of the file. Applications no longer need to talk to Baloo.
• Overall speed improvements
• Many more tests in the File Indexers

Compositor and Window Manager

Wayland Support

• new binary kwin_wayland
• kwin_wayland supports starting the X-Server it needs to connect to
