Tapper privileges are cut down: Tapper does not need full <code>root</code> power, two capabilities <code>cap_setuid</code> and <code>cap_setgid</code> are enough. Instead of <code>chmod u+s</code> the installer performs <code>setcap cap_setuid,cap_setgid=p</code>. Tapper drops all capabilities in the very beginning.

License for small supporting files changed to FSFAP.

Metainfo file is added.

The <code>setup.sh</code> script works for AltLinux (<code>configure && make</code> works in AltLinux, but building an RPM package from the provided spec file does not).

<em>Highlight:</em> The KDE layouter is added, it works for both X Window System and Wayland. There is a minor drawback, though: the KDE layouter cannot ring the bell.

<em>Breaking change:</em> Because of the KDE layouter addition, GSettings schema is changed. Check the layouter selection setting after updating Tapper.

Error reporting is improved in case if no suitable listener/layouter/emitter is found.

If layouter is not explicitly selected and the <code>XDG_SESSION_DESKTOP</code> environment variable is <code>gnome-xorg</code>, Tapper uses the GNOME layouter.

<code>BUGS.md</code> documents what information must be included into a bug report.

Tapper desktop support matrix is added to the Tapper home page.

Tapper RPM requires Agism RPM only if <code>gnome-shell</code> package is already installed. Also Tapper RPM recommends <code>dconf-editor</code> RPM.

Bug: Key codes in actions require <code>#</code> prefix, but in the command line <code>#</code> prefix is not allowed. Fixed: Key code are used everywhere with no prefix, as documented.

The <code>--autostart</code> and <code>--no-autostart</code> options respect the <code>--datadir</code> configuration option.

The <code>--autostart</code> and <code>--no-autostart</code> options respect the <code>XDG_CONFIG_HOME</code> environment variable.

Spaces are tolerated in actions (e. g. <code>KEY_CAPSLOCK = @1, 1</code>) in both settings and command-line arguments.

The <code>--dconf-editor</code> option is introduced to edit Tapper settings with the <code>dconf-editor</code> graphical tool.

The <code>--autostart</code> option is introduced to set up Tapper to start automatically when you log in. The <code>--no-autostart</code> option disables autostart.

The libinput listener respects the <code>XDG_SEAT</code> environment variable if it is set.

Bug: The GNOME layouter rings the bell regardless of the <code>--bell</code>/<code>--no-bell</code> option and setting. Thanks to papin-aziat and Vitaly for reporting.

Build: RHEL 8 build is fixed.

Minor changes in the documentation (HTML pages and man page).

<em>Highlight:</em> Tapper works in GNOME 41 and does not require “Unsafe Mode”.

<em>Important:</em> The GNOME layouter requires [Agism], a GNOME Shell extension, which should be installed and enabled. See “[Caveats/GNOME layouter does not work]” in [tapper(1)].

<em>Breaking change:</em> Since Tapper can’t hide input events from other programs, “interceptor” is renamed to “listener”: the <code>--interceptor</code> command line option is renamed to <code>--listener</code>, key in GSettings schema is also renamed.

<em>Highlight:</em> Tapper can emulate keystrokes. See “[Description/Actions]”, “[Description/Assignments]” and “[Examples/Advanced usage]” in [tapper(1)].

<em>Breaking change:</em> Because of ability to emulate keystrokes, the assignment syntax is changed. Keyboard layouts must be prefixed with <code>@</code> in order to distinguish between keyboard layouts and keys. Both command line and GSettings schema are affected.

Tapper drops unnecessary privileges as soon as possible. See “[Description/Security note]” in [tapper(1)].

Build: libjson-glib is not required any more. libevdev is required.

Build: <code>setup.sh</code> script are added to install required packages, it works for Arch, Debian, Fedora, Mageia, openSUSE, and Ubuntu.

<em>Highlight:</em> Tapper is tested in bunch of desktops: Cinnamon, GNOME Classic, KDE, LXDE, LXQt, Mate, Xfce. Tappers works perfectly in all these desktops, so “GNOME Shell” is dropped from Tapper headline. Now it is “a keyboard layout switcher for X Window System and Wayland”. GNOME Shell is still a primary target for Tapper though.

Bug fixed: Command line assignments didn’t override settings assignments.

GNOME detection is changed: The <code>XDG_CURRENT_DESKTOP</code> environment variable is retired, the <code>XDG_SESSION_DESKTOP</code> is analyzed instead.

Desktop file is updated so Tapper is always shown (not just in GNOME, as before).

Tapper home page is updated with getting instructions for Arch, Mageia and openSUSE.

The <code>--no-default-assignments</code> command line option is introduced. It is used for testing purposes and has little value for users.

Few corner cases are handled more gracefully:

• The <code>--interceptor=auto</code> command line option now selects XRecord interceptor regardless of <code>XDG_SESSION_TYPE</code> environment variable if XRecord is the only available interceptor (in other words, if libinput interceptor is disabled at build time). Earlier Tapper in such a condition fired assertion failure and aborted with core dump.
• Similarly, the <code>--layouter=auto</code> command line option selects GNOME layouter regardless of <code>XDG_SESSION_DESKTOP</code> environment variable if GNOME is the only available layouter. Earlier Tapper in such a condition fired assertion failure and aborted with core dump.
• Similarly, if Tapper is build with no interceptors or no layouters (useless but possible configuration), default assignments are not used to avoid error caused by bad arguments. Such error can confuse user since no arguments specified in command line.

<code>INSTALL.md</code> now includes build instructions for Mageia and openSUSE.

Build: <code>configure</code> options <code>--enable-libinput</code> and <code>--enable-x</code> are renamed to <code>--with-libinput</code> and <code>--with-x</code> respectively to follow Autoconf guidelines.

Build: New configure options <code>--with-glib</code> and <code>--without-glib</code> are introduced to decouple GLib usage from GNOME support. Now it is possible to disable GNOME layouter but still use GSettings to store configuration.

Build: The <code>--enable-author-testing</code> configure option is introduced. If author testing is disabled, some non-functional tests (e. g. cppcheck, spell check) are not run because there is no point in running these tests for packagers and end users.

Tests are reworked:

• Tapper configuration is respected now. For example, if Tapper is configured with the <code>--without-x</code> option, tests skip all checks that require the XRecord interceptor and/or the Xkb layouter.
• Execution environment is respected now. For example, if tests are run in console session, tests requiring X Window System are skipped.

The <code>--syslog</code> command line option is introduced.

Build: Empty <code>%{dist}</code> rpm macro confused make. This affected build on Arch if <code>rpm-build</code> is available. Thanks to Jozef Riha for reporting.

Bug: If keyboard layout name contains Unicode characters, Tapper might complain on bad JSON string (e. g. “unterminated string constant” or “invalid byte sequence in conversion input”). Thanks to Jozef Riha for reporting.

Bug: The last layout in the intro message was printed with no layout name. Thanks to Jozef Riha for reporting.

Build: <code>configure</code>/<code>make</code> failed on Ubuntu (unresolved references to the <code>glibmm</code> library).

<code>INSTALL.md</code>: Added (incomplete) instructions for Arch and Debian/Ubuntu.

Site: Added a link to project page @ SourceForge.

Site: Site search is added to the <em>Site map</em> page.
