ibus now supports X keyboard layouts and switching between them and/or input methods. X keyboard layouts can be added to the ibus context menu in addition to input method engines. This puts keyboard layouts and input methods on the same level for ibus users.
The ibus trigger shortcut, by default Control+Space, now toggles to the previously used input method instead of switching ibus on and off. The off-state is replaced by the default keyboard layout. The new behaviour is similar to how MacOS and ChromiumOS behave with respect to input method switching. There is a configuration option in ibus-setup to switch back to the previous Control+Space behaviour for those who prefer it. However this may be removed in the future: feedback on the new default behaviour is welcome.
Other trigger shortcut bindings specific to certain countries have been moved to the appropriate input method engine's configuration: only Control+Space is provided by default as a shortcut now. E.g. the Hangul key is now only defined for Korean engines, and Zenkaku_Hankaku is available only for Japanese engines only.
The ibus-gnome3 gnome-shell extension provides a gnome-shell indicator icon with menu and input method candidate window instead of usual gtk versions. The indicator uses text symbols to show the current input method or keyboard layout of image icons. Keyboard layouts are displayed as letter country codes (e.g. 'us', 'fr', 'de', etc) and native characters (like '中', 'あ') are used for input methods. ibus-gnome3 is provided in a ibus subpackage as a technology preview for Fedora 16. The plan is to integrate it into gnome-shell itself in a future release upstream hopefully in time for Fedora 17. ibus-gnome3 can be enabled using the Shell Extensions in 'gnome-tweak-tool'. See also Features/GnomeInputIntegration.
ibus has some support now for X compose keys (as provided by libX11 XIM) in a unified way for all GTK, QT and X11 applications. Currently support is available for US International mode (FIXME: check) and also cedilla mode if the desktop locale is Brazilian Portuguese.
ibus engines can now define XKB options. For example, when a user enables Indic engines provided by ibus-m17n, Alt_R will be automatically mapped to AltGr; if the user then switches back to ibus-anthy, AltGr will be unmapped again.
The eekboard on-screen keyboard can now be activated through IBus, in addition to desktop accessibility. See setup instruction for tablet PC.
ibus-gucharmap is a new input method engine providing Unicode input method, which supports in-place character-map view, character search based on Unicode names, and easy navigation with various keyboard shortcuts.
Tamil support has been added to Indic Typing Booster predictive text input method and supports Tamil-99 and Inscript layouts.
Fedora now includes font for Nastaleeq script, one of the main script styles used in writing the Perso-Arabic script, and traditionally the predominant style in Persian calligraphy.
Arabic script support for the Urdu language has been improved by adding following new font packages: nafees-naskh-fonts, nafees-nastaleeq-fonts, nafees-tehreer-naskh-fonts, nafees-riqa-fonts, and nafees-pakistani-naskh-fonts.
The WQY Microhei font is now used by default for Chinese. Chinese users requiring more fonts support can install them by yum groupinstall of 'simplified-chinese-support' or 'traditional-chinese-support'.
