 - Allow interactive `docker pull` in terminal only. Do not start additional 
   X terminal. [(#109)](https://github.com/mviereck/x11docker/issues/109)
 - Prefer starting terminal to ask for root password. Use additional X terminal
   only as a fallback. 
   [(#109)](https://github.com/mviereck/x11docker/issues/109)
### Fixed
 - **API FIX**: Preserve quoting in image command correctly. 
   Image commands like `sh -c 'ls && pwd'` previously failed.
   Instead `'ls && pwd'` sort of worked although it is weird.
   Now `sh -c 'ls && pwd'` works as intended and `'ls && pwd'` fails.
   [(#112)](https://github.com/mviereck/x11docker/issues/112)
 - `-t, --tty`: Long option was not parsed.
 - docker-for-win: Fixed IP check
   [(#102)](https://github.com/mviereck/x11docker/issues/102)
 - docker-for-win: Make sure container is terminated.
   [(#106)](https://github.com/mviereck/x11docker/issues/106)
 - docker-for-win: `--interactive`: Use `winpty` wrapper.
   [(#87)](https://github.com/mviereck/x11docker/issues/87)
 - MSYS2/Cygwin: Always use X over IP to serve e.g. `Xvfb.exe`, too.
   [(#123)](https://github.com/mviereck/x11docker/issues/123)
 - `--update`: Fixed `sed` parsing error for excerpt of `CHANGELOG.md`.

### Added
 - `-i, --interactive`: New option to run with an interactive TTY.
   [(#87)](https://github.com/mviereck/x11docker/issues/87)
 - `-t, --tty`: Replaces `--nothing`. Runs no X server, uses terminal only.
   Allows `x11docker -ti` similar to often used `docker run -ti`. 
 - `-q, --quiet`: Replaces `--silent`. Suppress x11docker messages.
### Deprecated
 - `--silent`: Use `--quiet` instead.
 - `--nothing`: Use `--tty` instead.

   [(#75)](https://github.com/mviereck/x11docker/issues/75)
 - `--sysvinit`: fixed startup failure due to missing container user name.

## [5.3.2](https://github.com/mviereck/x11docker/releases/tag/v5.3.2) - 2018-11-08
### Added
 - `--user=RETAIN`: Keep user settings of image instead of creating a new one.
   [(#85)](https://github.com/mviereck/x11docker/issues/85)
### Fixed
 - `gnome-terminal` did not appear for password prompt or `docker pull`.
   [(#84)](https://github.com/mviereck/x11docker/issues/84)
 - Watch container pid 1 instead of container pid itself. Avoids issue on NixOS
   where users cannot see processes of other users, root or docker in this case.
   Throw error if x11docker cannot watch container pid 1 due to `hidepid=2`.
   [(#83)](https://github.com/mviereck/x11docker/issues/83)

## [5.3.1](https://github.com/mviereck/x11docker/releases/tag/v5.3.1) - 2018-10-22

 - `--sharedir DIR`: Appending `:ro` to `DIR` restricts to read-only access.
### Fixed
 - `--systemd --verbose`: journalctl.log was not shown.
 - `--systemd`: fixed slow dbus startup.

   happened e.g. in Gnome Wayland session.
   [(#74)](https://github.com/mviereck/x11docker/issues/74)
 - `--nxagent`: X authentication was set to `xhost +`. 
   Now restricted to cookie using clients again.

 - `--xwin`: New option for Xwin X server of Cygwin/X on MS Windows.
 - `--sharessh`: New option to share SSH agent authentication socket from host.
   [(#59)](https://github.com/mviereck/x11docker/issues/59)
 - `--name`: New option to set container name.
   [(#61)](https://github.com/mviereck/x11docker/issues/61)
 - `--cachebasedir`: Set custom cache base directory. Replaces `--cachedir`.
 - `--homebasedir`: Set base directory where to store folders for `--home`.
### Changed
 - **API CHANGE**: Syntax changed for custom `DOCKER_RUN_OPTIONS` 
   [(#58)](https://github.com/mviereck/x11docker/issues/58). New:
```
   x11docker [OPTIONS] --  DOCKER_RUN_OPTIONS -- IMAGE [COMMAND [ARG1 ARG2 ...]]
```
   Previous syntax, still valid, but deprecated:
```
   x11docker [OPTIONS] -- "DOCKER_RUN_OPTIONS"   IMAGE [COMMAND [ARG1 ARG2 ...]]
   x11docker [OPTIONS] -- IMAGE COMMAND ARG1 -- ARG2
```
   **BREAKS** due to wrongly parsed ` -- ` :
```
   x11docker [OPTIONS] -- "DOCKER_RUN_OPTIONS"   IMAGE COMMAND ARG1 -- ARG2
```
   Valid:
```
   x11docker [OPTIONS] --  DOCKER_RUN_OPTIONS -- IMAGE COMMAND ARG1 -- ARG2
```
 - `--pulseaudio` allows optional argument `=tcp` or `=socket`.
   Defaults to connection over shared socket on Linux and to TCP connection
   on MS Windows. On Linux both modes are possible, on MS Windows TCP only.
 - `--verbose`: takes optional argument `c` for colored output, eg `-vc`.
### Deprecated
 - `--cachedir`: Use `--cachebasedir` instead.
### Removed
 - `--ipc`: Use `--hostipc` instead.
 - `--net`: Use `--hostnet` instead.
 - `--sharewayland`: Use `--wayland` instead.
 - `--setwaylandenv`: Use `--wayland` instead.
 - `--dbus-daemon`, `--dbusdaemon`: Use `--dbus-system` instead.
 - `--add`: Use `--runfromhost` instead.
### Fixed
 - `--xpra`: Support of outdated xpra version v0.17.6 that is still
   distributed in debian stretch and buster.
 - `--xpra`: Set x11docker cache folder as xpra socket folder.
   [(#69)](https://github.com/mviereck/x11docker/issues/69)
 - `--xpra`: Check if `xhost` is available if xpra version 2.3.1 has cookie 
   issue. [(#57)](https://github.com/mviereck/x11docker/issues/57)
 - `--xpra-xwayland`: Set Weston `--fullscreen` to get Xwayland resolution
   matching host display. Weston v4.0.0 seems to interpret screen size 
   settings in `weston.ini` different than before.
 - `--pulseaudio`: create socket to share instead of using existing one.
   [(#71)](https://github.com/mviereck/x11docker/issues/71)
 - `--pw gksu`, `--pw gksudo`: Disable keyboard grabbing to avoid issues
   with Gnome 3 Wayland session.
 - Don't fail on missing password prompt frontend if no password is needed.

## [4.3.6](https://github.com/mviereck/x11docker/releases/tag/v4.3.6) - 2018-07-03
### Changed
 - `--auto`: Prefer `--xpra` and `--xephyr` over `--nxagent` again.
   `--nxagent` too often has issues with extension Composite.
 - `--xorg`: Allow running Xorg as root from within X 
   if `/etc/X11/Xwrapper.config` is not configured to allow it.
 - `--xpra`, `--xpra-xwayland`: Set maximal `--quality 100`.

### Fixed
 - `--xpra`: Check for tty timeout had a bug that caused all clients 
   of same server to terminate if one client was closed.
 - `--xorg`: Secure check for free tty instead of guessing it.
 - `--xorg`: Error messages appear on new display instead of host display.
 - `--sysvinit`, `--runit`, `--openrc`: Clean shutdown on CTRL-C / SIGINT.
 - `x11docker-gui`: Fixed issue with self-terminating on cleanup.
 - errors within subshells did not reliably terminate x11docker.
 - `--tini`: Check for `docker-init` in snap installs of docker.
   [(#51)](https://github.com/mviereck/x11docker/issues/51)
 - `--dbus-system`: Disable services `org.freedesktop.hostname1` and 
   `org.freedesktop.locale1` if not running with `--systemd`. Can cause
   container shutdown after some time.
 - `--hostdisplay`: Fixed possible `xhost -SI:localuser:$USER`. 
   [(#53)](https://github.com/mviereck/x11docker/issues/53)
 - `/etc/shadow`: Fixed fedora issue with `000` file access.
   [(#53)](https://github.com/mviereck/x11docker/issues/53)


## [4.3.5](https://github.com/mviereck/x11docker/releases/tag/v4.3.5) - 2018-06-21
### Changed
 - `x11docker-gui` runs from console, too.
### Fixed
 - `--xorg` and others on TTY failed due to xinit in subshell.
   (regression in v4.3.4).
 - `--weston --size` failed on tty, have to specify drm backend for check.
 - timezone syncing: If setting `TZ`, positive offsets have been set wrong.
 - timezone syncing: Regard `TZ` from host, not only `/etc/localtime`.
 - `--xpra`: catch timeout disconnection that happens if using another tty
   longer than 60s. Restart xpra client in that case.

## [4.3.4](https://github.com/mviereck/x11docker/releases/tag/v4.3.4) - 2018-06-15
### Changed
 - `--dbus-system --sharecgroup`: support of `elogind` in container.
 - Timezone syncing: Do not mount-bind `/etc/localtime`. 
   If tzdata is missing in image, but host and image have same libc,
   provide current timezone file only. Create symlink `/etc/localtime` within
   container. If all that fails, set `TZ` with offset to UTC.
   [(#50)](https://github.com/mviereck/x11docker/issues/50)
 - Improved `message.fifo` handling from within dockerrc and container.
 - Disentangled final code sequence of xinit and docker run.
### Fixed
 - Check for running docker daemon in dockerrc instead of using `pidof`.
   [(#49)](https://github.com/mviereck/x11docker/issues/49)
 - Show error message if X server fails to start. Supress warning if needless.
 - `--xpra`: Do not exit on `failed` in xpra server log. (seen on Ubuntu 18.04).
 - `--xorg`: Show `Xwrapper.config` warning if `needs_root_rights=yes` is 
   missing. (Seen on Ubuntu 18.04).
 - `--xorg`: Password prompt did not appear on new display.
 - `--nothing`: Bugfix password prompt on console.
 - `--nothing`: Avoid startup error message.
 - `--nothing`: Don't start X if running within X / dependency check issue.
 - `--nothing`: Pull request for non-local images was invisible.
   
## [4.3.3](https://github.com/mviereck/x11docker/releases/tag/v4.3.3) - 2018-06-05
### Changed
 - `--no-init` or missing `tini` resp. `docker-init`: use `sh` as PID 1
   for desktop environments (`--desktop`) to allow logout.
### Fixed
 - fedora 28: Check for docker daemon with name `dockerd-current` 
   [(#49)](https://github.com/mviereck/x11docker/issues/49)
 - `--auto`: Prefer `--hostdisplay` for seamless apps if nothing else is 
   available.
 - `--wayland`, `--weston`, `--kwin`, `--hostwayland`: 
   Show error and exit if no wayland environment can be provided.
 - dockerrc messages forwarded to logfile fifo. (fixes "unknown file descriptor").

## [4.3.2](https://github.com/mviereck/x11docker/releases/tag/v4.3.2) - 2018-06-03
### Changed
 - `x11docker-gui` is interactive now. Live preview of generated command. 
   Starting multiple x11docker instances possible. Copy-to-clipboard button.
 - `x11docker-gui`: create list of installed images every time x11docker 
   or x11docker-gui runs and has enough permissions. Image list is used in
   x11docker-gui in image combo.
 - `--cleanup`: Running as root not mandatory.
 - `--clipboard`: support `xsel` additional to `xclip`.
### Fixed
 - Starting in pure Wayland environments failed (regression in v4.3.0).
 - `--wayland`, `--weston`, `--kwin` in pure Wayland: detect screen size.
 
## [4.3.1](https://github.com/mviereck/x11docker/releases/tag/v4.3.1) - 2018-05-29
### Changed
 - `--auto`: prefer `--nxagent` over `--xpra` and `--xephyr`. Reasons:
   Faster startup than `--xpra`. Flexible display size opposed to `--xephyr`.
   Since Ubuntu 18.04 available to broader range of users than before.
 - `--runfromhost` can be specified multiple times now.
 - `--runasroot` can be specified multiple times now.
 - `--dbus-system` and init systems: remove useless or failing dbus services.
 - `--systemd`: mask some useless or failing units.
 - set `DISPLAY`, `XAUTHORITY`, `WAYLAND_DISPLAY` and `XDG_RUNTIME_DIR`
   in `docker run` command for easier custom use of `docker exec`.
### Fixed
 - `--xpra`: Deny to start xpra >2.2.5 and <r19519 due to MIT-SHM bug.
   Show message that startup is only possible with `--hostipc`.
   xpra bugticket: https://xpra.org/trac/ticket/1858
 - `--xpra`: Warning and workaround for cookie bug in xpra >=v2.3.
   xpra bugticket: https://www.xpra.org/trac/ticket/1859
 - `--xpra` in desktop mode: Allow closing client window, don't restart.

## [4.3.0](https://github.com/mviereck/x11docker/releases/tag/v4.3.0) - 2018-05-26
### Added
 - `--stdin`: Forward stdin of x11docker to image command.
 - `--showpid1`: Echo host PID of container PID 1 on stdout.
### Changed
 - `--security-opt=no-new-privileges` for init systems and `--dbus-system`.
   Now default for all options except `--sudouser` and `--cap-default`.
 - `--dbus-system` and `init` system options: Run all except a few dbus
   system services manually and show security warning message. Manual
   start needed due to `no-new-privileges`, polkit setuid helper fails.
 - Minimize or delete `/etc/pam.d/su` and delete `/etc/pam.d/sudo`.
   Avoids security leak that would allow switching to root in container
   if `PAM` configuration allows it and capabilities for `su` are given.
 - Remove `/bin/sh -c` from extracted CMD image command.
 - Regard `WORKDIR` in image, use it instead of `HOME`. 
   [(#45)](https://github.com/mviereck/x11docker/issues/45)
 - Logfile handling with fifo/named pipe.
 - `--auto`: Tightened dependency check.
 - Improved process watching using less resources. Faster shutdown.
 - `x11docker-gui`: New structure using tabs.
 - Some code cleanup.
### Fixed
 - Don't set `-title` in `Xephyr` command. Xephyr bug: Releasing keyboard
   and mouse after grab (ctrl+shift) does not work with `-title`. 
   [(#44)](https://github.com/mviereck/x11docker/issues/44)
 - `--nxagent`: Fixed keyboard layout issue, don't use setxkbmap.
 - `--nxagent`:  Regard `--keymap`.
 - `--nxagent`: Removed extension Composite, caused some issues.
 - `--exe`: Don't pass file descriptors to host executeable.
 - `--wayland` Works with prissy GTK3 applications (e.g. xfce4-terminal) again,
   needed user switching in `--dbus-system` for unknown reasons.
 - `--showid` failed with sudo due to missing file descriptors. Using mkfifo now.
 - Don't forward stdin as default, can cause trouble if empty. use `--stdin` instead.
 - `--xorg`: disable screen saver [(#46)](https://github.com/mviereck/x11docker/issues/46)
   
## [4.2.1](https://github.com/mviereck/x11docker/releases/tag/v4.2.1) - 2018-05-10
### Added
 - Forward `stdin` of x11docker to container command with a named pipe/fifo.
### Changed
 - `x11docker-gui`: Use stdin for kaptain grammar transmission. Don't use cache.
 - `--dbus-system`: Don't create `--tmpf /tmp --tmpfs /run --tmpfs /var/run --tmpfs /run/lock`.
   [(#43)](https://github.com/mviereck/x11docker/issues/43)
 - Some internal improvements for faster startup and shutdown.
### Fixed
 - `x11docker-gui`: fixed x11docker startup failure due to changed stdout output.

## [4.2.0](https://github.com/mviereck/x11docker/releases/tag/v4.2.0) - 2018-05-04
### Added
 - `--group-add`: New option to add groups to container user. 
   Needed instead of ` -- --group-add` to cover user switching setups, too.
 - `--showid`: New option to show container ID on stdout.
 - `--runfromhost`: Replaces deprecated `--add` to have a meaningful option name.
   Similar to already existing `--exe`, but integrates with container.
 - `--runasroot`: New option to run command as root in container on startup.
### Changed
 - `--gpu`: Support for automatical installation of NVIDIA drivers in container. 
   Limited to `glibc` based image systems. 
   [(#41)](https://github.com/mviereck/x11docker/issues/41)
 - `elogind` support for `--sysvinit`, `--openrc` and `--runit`.
   See also [elogind in container: elogind#52](https://github.com/elogind/elogind/issues/52)
 - `--systemd`: If host does not run `systemd`, create `/sys/fs/cgroup/systemd`.
 - `--dbus-system`: wait for bus socket to be ready before continuing.
 - `--tini`: Use `tini-static` from `~/.local/share/x11docker` or 
   `/usr/local/share/x11docker` if available. Show message for this possibility
   if `/usr/bin/docker-init` is missing. (Widespread docker packaging issue).
   [(#23)](https://github.com/mviereck/x11docker/issues/23)
 - Avoid user switching except for `--systemd`, `--sysvinit`, `--openrc` and 
   `--runit`. [(#42)](https://github.com/mviereck/x11docker/issues/42)
 - Outsourced `x11docker.png` from `x11docker-gui`.
 - No default output of container ID on stdout anymore. Use `--showid` instead.
 - `--silent`: Do not show error messages except in logfile.
 - `--weston[-xwayland] --fullscreen`: Use X backend if possible to prevent
   possible crash with nested fullscreen weston in host drm weston.
 - Disabled forwarding of `stdin` to container, has not been reliable.
### Deprecated
 - `--add` changed its option name to `--runfromhost`.
### Fixed
 - Don't share or link `/tmp/.Xn-lock` as usefulness is in doubt. 
   Avoids issues with `x11docker/xwayland`.
 - `--stdout --showid:` Make sure container ID is shown first.

## [4.1.1](https://github.com/mviereck/x11docker/releases/tag/v4.1.1) - 2018-04-12
### Changed
 - Mount nothing into `/tmp` as init cleanups may try (and fail) to delete it. 
 - Write or link into `/tmp` only _after_ possible init cleanup.
 - Mount X socket r/w again as there is no longer a risk due to `/tmp` cleanups.
 - `--debug`: Some changes for more useful debugging output. 
   Drop `set -x` in main code, instead `set -Eu` with `trap ERR`.
 - `--update`/`--update-master`: Show excerpt of `CHANGELOG.md`.
 - Check `ENTRYPOINT` for init entries `/tini|/init|/systemd` and disable it 
   if x11docker already runs an init. (Default: `--tini`.)
### Fixed
 - `x11docker-gui` regards new output of container ID now that confused output
   of `x11docker/kaptain` and prevented start of `x11docker`.
 - Mount `WAYLAND_DISPLAY` and `DISPLAY` at `/` instead of `/x11docker/` 
   in container. 
   Avoids a docker bug that only sometimes causes startup failure 
   `stat /run/user/1000/wayland-600: no such file or directory`.
   Occasionally docker is confused about a mount point inside of a mount point.
   Avoiding that now. 
   However, issue only seen with shared Wayland sockets and never with X 
   sockets, maybe due to different option positions in `docker run` command.
 - `--workdir`: Avoid double setting of `--workdir` in docker command 
   if x11docker option `--workdir` is set. Caused no trouble, though.

## [4.1.0](https://github.com/mviereck/x11docker/releases/tag/v4.1.0) - 2018-04-08
### Added
 - `--update-master` updates to lastest x11docker master version. 
   (Formerly job of `--update`).
### Changed
 - `--update` updates to latest x11docker release on github. 
   (Formerly: latest master version).

## [4.0.0](https://github.com/mviereck/x11docker/releases/tag/v4.0.0) - 2018-04-07
### Changed
 - Outsourced changelog from x11docker source code to `CHANGELOG.md`. [(#38)](https://github.com/mviereck/x11docker/issues/38)
 - Follow guidelines of [Keep a Changelog](http://keepachangelog.com/en/1.0.0/).
 - Stricter compliance to [Semantic Versioning](https://semver.org/) rules.
### Notes
 - Previous version links in changelog lead to history tree leafs with 
   corresponding `x11docker` script.
 - Upcoming version links in changelog will lead to corresponding [releases](https://github.com/mviereck/x11docker/releases).

## [3.9.9](https://github.com/mviereck/x11docker/blob/8abded01de9482ef70195550f936c9f07668b486/x11docker) - 2018-04-06
### Changed
 - Removed `--security-opt=no-new-privileges` for 
   `--systemd`/`--sysvinit`/`--runit`/`--openrc`.  (Undoes some changes 
   from V3.9.8.1). Will be reintroduced after further checks, caused issues 
   with `x11docker/deepin` and `x11docker/cinnamon`.
 - `--env`: set environment variables in `docker run`, too. 
   Makes them available within `docker exec`.

## [3.9.8.5](https://github.com/mviereck/x11docker/blob/6227a1eebc5b63df305822896d7360a14440caf4/x11docker) - 2018-04-05
### Changed
 - `finish()`: run `docker stop` before creating `timetosaygoodbye` for 
   more graceful shutdown [(#37)](https://github.com/mviereck/x11docker/issues/37)
### Fixed
 - Set correct `XAUTHORITY` in setup script.
 - Disable `User` in systemd journal service, can fail in restricted setups.

## [3.9.8.4](https://github.com/mviereck/x11docker/blob/d74fa2defceb538d8c9e90932d48f23cae0f102b/x11docker) - 2018-04-04
### Added
 - `--workdir` to set working directory different from `HOME`. ([#36](https://github.com/mviereck/x11docker/issues/36))
### Changed
 - `--systemd`/`--dbus-system`: changed `su` command to remove `sh` from pstree.
### Fixed
 - User group entry in `/etc/group` had wrong syntax.

## [3.9.8.3](https://github.com/mviereck/x11docker/blob/6ce5d2cbd7a14556723a3c8e1163988f2ddda8ce/x11docker) - 2018-04-04
### Fixed
 - `--dbus-system`: must not set `--security-opt=no-new-privileges`, 
   important services like `polkitd` fail.

## [3.9.8.2](https://github.com/mviereck/x11docker/blob/a58e6808254ce78eb528010584ff9d7ef9b8aa26/x11docker) - 2018-04-03
### Changed
 - disable entrypoint `tini` if x11docker already runs an init system 
   (default: `--tini`/`docker-init` from docker). ([#34](https://github.com/mviereck/x11docker/issues/34))

## [3.9.8.1](https://github.com/mviereck/x11docker/blob/75f79c9888beee08ca08c42c5f70feaa0f02cd30/x11docker) - 2018-04-03
### Changed
 - `--security-opt=no-new-privileges` now always set except for `--sudouser`.
   It does not harm switching from root to less privileged users. 
   _(Note: is undone in v3.9.9)_
 - setup script with user switching: `exec su` instead of `su` to avoid 
   root shell in parent tree. `su` is now immediate child of `init`.
### Added
 - show container ID on stdout ([#36](https://github.com/mviereck/x11docker/issues/36)). 
   Can be catched e.g. with `read containerID < <(x11docker [...] )`.

## [3.9.8.0](https://github.com/mviereck/x11docker/blob/a4067993a91f39bce145b48406453f786d1707eb/x11docker) - 2018-04-02
### Changed
 - Removed `Xtermlogfile`, using `Dockerlogfile` instead. 
   Strange: solved missing output with `--pw=su` or `--pw=sudo`, too.
### Fixed
 - Escape special characters in `--env`, `ENV` and image command. 
   (Adresses [#34](https://github.com/mviereck/x11docker/issues/34), too, now solved better). _(Note: still have to escape some other optional arguments)_

## [3.9.7.9](https://github.com/mviereck/x11docker/blob/7776de0f3128a679239037567626cca09f472ee5/x11docker) - 2018-03-31
### Changed
 - Store parsed parts of `Imagecommand` in `''` to allow constructs like
   `sh -c "cd /etc ; xterm"`
### Fixed
 - Added `--rm` to `docker run` of environment check. ([#34](https://github.com/mviereck/x11docker/issues/34))

## [3.9.7.8](https://github.com/mviereck/x11docker/blob/4d619bfbcae605b25ee93778936245019a8a7020/x11docker) - 2018-03-31
### Fixed

## [3.9.7.6](https://github.com/mviereck/x11docker/blob/65305faba992415b8b255a4fac7e89c4417e5a1e/x11docker) - 2018-03-30
### Changed
 - mount X socket and lockfile read-only to protect from `/tmp` init cleanups.
 - minor improvements of init system initialization
### Fixed
 - remove checks for `--userns-remap` and `--selinux-enabled`. [(#33)](https://github.com/mviereck/x11docker/issues/33)

## [3.9.7.5](https://github.com/mviereck/x11docker/blob/0f0b138db7c2f3093511fae7583b34bc44db3423/x11docker) - 2018-03-30

   (Was missing after switch from tcp to socket connection).
 - `--runit`: add softlink for X socket in `x11docker.CMD.sh` for 
   compatibility with `runit` on debian.

## [3.9.7.3](https://github.com/mviereck/x11docker/blob/57e34236dca42e05434a304c77f61202d678398a/x11docker) - 2018-03-21
### Changed
 - `--pulseaudio`: share socket `XDG_RUNTIME_DIR/pulse` 
   instead of connecting over tcp.

## [3.9.7.2](https://github.com/mviereck/x11docker/blob/25201b916159b2f77d6c6188ea875d80004733d1/x11docker) - 2018-03-20

   `--wayland` does the job.
### Fixed
 - `writeaccess()` handles user group names with spaces in it. [#30](https://github.com/mviereck/x11docker/issues/30)
 - `--env`: regard whitespace. Still need to handle special chars like "\'$.

## [3.9.7.1](https://github.com/mviereck/x11docker/blob/4aaa1cf3c9de7b5924a05cd1ace29e60b3903327/x11docker) - 2018-03-16
### Fixed
 - alpine images: `/etc/shadow` entry must be `/bin/sh`, `--dbus-system` with `su` fails with `/bin/bash`.
 - openSUSE: `finish()`: replace `bc` with bash-only calculation, `bc` is missing on openSUSE.

## [3.9.7](https://github.com/mviereck/x11docker/blob/82e573068bfe78a9650f40cb5b98df9b1e08d483/x11docker) - 2018-03-15
### Changed
 - structure change: don't `sleep 1` for setup; instead wait for it in `x11docker.CMD.sh` resp. run `su` or `init` in setup
 - `xinitrc`: some cleanup
 - `--verbose`: power of moo
 - SSH with `--hostdisplay`: set `--hostipc`, `--hostnet` and `--trusted`. Do not use X-generated cookie, bake it myself.
### Fixed
 - openSUSE/fedora: `ps` check for container pid; fixed desktop logout issue, too.
 - `---weston`/`--weston-xwayland`: do not start drm backend if started within X without `DISPLAY` -> crashed host X.
 - regard SSH session, assume tty if `DISPLAY` is empty.
 - `--hostdisplay`: don't set keymap.

## [3.9.6.1](https://github.com/mviereck/x11docker/blob/1e482bc9341a6c22771b3ba602edb847e25d6d82/x11docker) - 2018-03-10

### Fixed
 - Store keyboard layout (xkb_keymap) in separate file, not in xinitrc. Set on all X servers. [#25](https://github.com/mviereck/x11docker/issues/25)

## [3.9.4.1](https://github.com/mviereck/x11docker/blob/68a7a529b807f40d102842ebc3fe16ca3435b771/x11docker) - 2018-03-06

 - plasmashell added to possible window managers.
### Fixed
 - `--exe`: avoid possible hostexe options with `basename` for `$Hostexebasename`.
 - typo checking `/tmp/.Xn-lock`.
 - checking free display number: race condition if starting two x11docker instances at same time, second one failed because display number already in use.

## [3.9.2.1](https://github.com/mviereck/x11docker/blob/3c28c1b61596fbc8a7e2b3ea0bbbe75dbc320fc4/x11docker) - 2018-01-29

### Changed
 - `finish()`: more precise check with pid and name before killing background pids.
### Fixed
 - add groups `video` and `audio` in `docker run` if `su` is not used in container. `/etc/group` changes by dockerrc seem to be not regarded in that case.

## [3.9.1.9](https://github.com/mviereck/x11docker/blob/f789a74ceab2f547b3d2939a5e23f21b32c0cd7c/x11docker) - 2018-01-17

 - run init system `tini` as default with `docker run --init`.
 - `-W` is now `--wayland` instead of `--weston`, `-T` for `--weston` now.
 - container user password: `x11docker` (creating volume `/etc/shadow`).
 - `--sudouser`: create user with docker run options instead of createuser script.
 - `--sudouser`: create `/etc/sudoers.d/$Benutzer` with docker exec in dockerrc.
 - `--sudouser`: create `/etc/sudoers.d/$Benutzer` instead of adding groups `wheel` and `sudo`.
 - createuser.sh: check for `useradd`, if missing use `adduser` (fits fedora and alpine/busybox as well).
 - $Sharefolder/stdout+sterr: `chmod 666` to allow access with `--user`.
 - `--exe` and `--xonly`: regard `--home` and `--homedir`, `--user` and `--hostuser`.
 - check pids before calling `mywatch()`.
 - colored logfile output.
 - `--verbose`: green colored output for logfile titles and verbose() lines.
 - set env `DISPLAY` `XAUTHORITY` and `WAYLAND_DISPLAY` in x11docker.CMD.sh as systemd eats them otherwise.
 - use docker run option `--tmpfs` for `/tmp`, `/var/tmp` and `/run` instead of `--volume=/tmp`.
 - changed container share folder `/tmp/x11docker` to `/x11docker` to avoid issues with `--tmpfs /tmp`.
### Fixed
 - in createuser.sh: `adduser` failed with fedora based images, use `useradd` and `usermod` instead.
 - `--pw=gksu`: avoid wrong docker startup error message, use nohup in dockerrc.
 - `--hostdisplay` with `--gpu` needs trusted cookies.
 - `--xpra` with `--hostuser`: create `/run/user/$Hostuseruid` if missing.

## [3.7.2](https://github.com/mviereck/x11docker/blob/e062b07b91b87a1b9b26d10e41d0d7dd1c3b6299/x11docker) - 2017-11-11

### Changed
 - read host cookie with xauth if XAUTHORITY is empty, can happen with xdm.

### Fixed
 - fixes for gksudo and lxsudo.

 - `--xhost`: always disabling with `no_xhost()`, afterwards setting `--xhost`.
### Deprecated
 - `--kwin-native`, too much trouble, but less use.
### Fixed
 - `--weston`/`--weston-xwayland`: set backend in compositor command, weston's autodetection can fail.
 - `--kwin`/`--kwin-xwayland`: set backend in compositor command, kwin's autodetection can fail.
 - `--kwin-xwayland`: set keyboard layout.

 -  check for X extension `Security` with xdpyinfo
 -  `--clipboard` for `--hostdisplay`: enable `--trusted` and `--ipc`, show warning.
 -  xpra startup after xinitrc, not inside. For better error handling

 - do not disable SELinux if `--ipc` is set
### Fixed
 - fedora: `--xorg`: add `-keeptty` if running from tty

 - `--hostuser` to set host user different from  $(logname)
 - `--desktop`: no longer deprecated, easier to understand and remember than `--wm=none`

   Compare: http://www.projectatomic.io/blog/2015/06/using-volumes-with-docker-can-cause-problems-with-selinux/
 - install to `/usr/bin` instead of `/usr/local/bin` to support root
 - `chmod 755` instead of `+x` in installation
 - check if docker is installed
 - check if docker daemon is running (with ifconfig)

 - check for xpra `--dpi` bug in 2.1 series
 - xpra `--start-via-proxy=no` for xpra >= 2.1
 - `--nxagent`: temporary `xhost +SI:localuser:$Hostuser` workaround as it fails again to authenticate, nxagent does not divide between `XAUTHORITY` and `--auth`

 - show `docker pull` output in a terminal window
 - allow `--hostdisplay` with `--xonly`. May at least be usefull to create an untrusted cookie.
 - outsourced docker startup from xinitrc
 - copy host cookie into $Cachefolder for compatibility with gksu
 - use gksu/gksudo if available
 - `--showenv` for `--xonly`
 - `finish()`: try `docker stop $Containername`

 - allow root to start x11docker, use `$(logname)` for X server and as container user
### Deprecated
 - `--root`: Can be achieved with `--hostuser=root`
 - `--no-password`: check if docker can run without password makes `--no-password` needless. Still possible with `--pw none`
### Fixed
 - `&, &&, ;, <, >, |` and the like possible in image command again
 - bugfixes in part "check window manager"
 - repeating error message if `waitforlogentry()` failed

## [3.5.11](https://github.com/mviereck/x11docker/blob/27f52c9edb28518568e8f6881a1300ca4aea4f2b/x11docker) - 2017-07-12
### Changed
 - pull image if not available before calling `docker run`

## [3.5.10](https://github.com/mviereck/x11docker/blob/dbd85cfc9f26948ddf8e27075923ff673dc5a89b/x11docker) - 2017-07-12
### Fixed
 - regard `ENTRYPOINT` in dockerrc

## [3.5.9](https://github.com/mviereck/x11docker/blob/623c20b427b50fc16c127c760688cfbb556c0b8b/x11docker) - 2017-07-09
### Changed
 - `--home` with `--user=(unknown)`: only show warning (instead of error) not creating persistent home
 - do not set write permissions on `--home` or `--homedir` folder for different users than `$USER` or `--user`. (Not x11docker's job)
 - do not set `--read-only` if `--user=0`
### Fixed
 - chown x11docker_CMD to host user to avoid permission issues in $Sharefolder
 - `--user`: use matching gid, gid was set to same as uid

## [3.5.8](https://github.com/mviereck/x11docker/blob/fc88928119202eef80d6e3eba788fcd367dbc629/x11docker) - 2017-06-07
### Added
 - `--xhost STR`: to set `xhost STR` in xinitrc. 
 - `--xvfb` to explicitly use Xvfb and to clearly use Xdummy on `--xdummy`
### Changed
 - `--kwin-native`: always share Wayland (`--sharewayland` `--waylandenv` `--dbus`)
 - docker run `--read-only --volume=/tmp` to restrict container filesystem as read-only (except for `--sudouser`)
 - `--xorg` supports `--rotate`. (Xephyr could, but crashes -> Xephyr bug. Nxagent, Xdummy, Xvfb and Xwayland refuse this.)
 - Xdummy script in $Cachefolder forked from https://xpra.org/trac/browser/xpra/trunk/src/scripts/xpra_Xdummy
 - calculate VideoRam in xorg.xdummy.conf (instead of fat hardcoded 256000 kb)
### Deprecated
 - `--xhost+`: use `--xhost STR` instead.
### Fixed
 - `--nxagent`: due to update? must set nxagent -ac (=xhost +) temporary to allow xinit
 - allow `--wm` for `--kwin-xwayland`

## [3.5.7](https://github.com/mviereck/x11docker/blob/6d8a4cd471f31e7053a10390ab2ca3f90ae80239/x11docker) - 2017-06-28
### Changed
 - usage info for HTML5 web application setup
 - redirect verbose output to &3 to show it in subshells, too, and to avoid possible collision with read < <()
 - `--env`: set custom environment variables in dockerrc instead of in docker run
 - removed `unix` in $Newxenv for DISPLAY to make xpra ssh setup easier
 - Xdummy-Xwayland: new X server to provide `--gpu` for `--xdummy` based on weston, xwayland and xdotool
 - always enable extension Xtest on `--xdummy` to allow xpra access
 - share X socket to /tmp, create .X11-unix in dockerrc and softlink socket. This avoids writeable X11-unix in $Cachedir.
 - `--setwaylandenv`: env now set in dockerrc instead of docker command

## [3.5.6](https://github.com/mviereck/x11docker/blob/1f6496421f958d5ebf4fcf9abbe6e5d51d19f212/x11docker) - 2017-06-21
### Added
 - `--sudouser`: reincarnated option to give sudo without password to container user.
### Changed
 - docker command one-liner extended to dockerrc. dockerrc creates x11docker_CMD. Can always extract image command without additional password prompt and create some environment.
 - create `/tmp/XDG_RUNTIME_DIR` and softlink to wayland socket in container due to some KDE issues (`XDG_RUNTIME_DIR` must be owned by user). Fails with different `--user`
 - create `/tmp/.X11-unix` with 1777 in container to allow new X sockets (especially for startplasmacompositor). Drawback: container writeable folder in cache
 - warning with hint to use `--xpra-xwayland` if `--scale` is used with `--weston-xwayland`.
 - shorter sleep in finish()
 - don't search for deprecated `/tmp/x11docker` in checkorphaned()
### Fixed
 - avoid pointless warning about `XTEST` if not using xpra
 - typo preventing start of `--kwin` and `--kwin-native` (`-width` instead of `--width`)
 - bugfix parsing option `--wm`
 - `export $Hostxenv` in error() was empty if called in xtermrc

## [3.5.5.2](https://github.com/mviereck/x11docker/blob/547aea540aed165fc22def77724caccbd6424c63/x11docker) - 2017-06-10
### Changed

## [3.5.5.1](https://github.com/mviereck/x11docker/blob/1867023c5913a09ed63f98c3d28e9b19f1b332b2/x11docker) - 2017-06-10
### Fixed
 - bugfix in `--auto` always choosing `--xorg`

## [3.5.5](https://github.com/mviereck/x11docker/blob/e6021187f59caef2a49b36e02417ec79591c7f1d/x11docker) - 2017-06-09
### Changed

## [3.5.4](https://github.com/mviereck/x11docker/blob/c09d6f3022ddf2c0ab6862e0f3db6ab6e9fa9c53/x11docker) - 2017-06-02
### Changed
 - disable extension `XTEST` if using wm from host (to avoid abuse of context menu of openbox and the like)
### Fixed
 - set rw access for `/dev/dri` ([#12](https://github.com/mviereck/x11docker/issues/12))

## [3.5.3](https://github.com/mviereck/x11docker/blob/870a63b67480caedb7645011666a325dbdbb8ce7/x11docker) - 2017-05-29
### Added
 - `--sharedir` replaces `--volume` to avoid confusion
### Changed
 - update `usage()`
 - mount $Sharefolder and its content read-only
 - remove X11-unix from $Sharefolder
 - set read-only for `/dev/dri` on `--gpu`
 - `--security-opt=no-new-privileges` added to docker run
### Deprecated
 - `--volume` is now called `--sharedir` due to different syntax than docker option `--volume`
### Fixed
 - `--pulseaudio`: get and use IP of container instead of docker0 IP range ([#11](https://github.com/mviereck/x11docker/issues/11)), disabling TCP module on exit

## [3.5.2](https://github.com/mviereck/x11docker/blob/d88d32605ece42324f14cf41e54482888ae539c4/x11docker) - 2017-05-22

### Added
 - `--output-count` to set amount if virtual screens/desktop windows for Weston, Kwin, Xephyr
 - `--westonini` to specify a custom weston.ini for `--weston` and `--weston-xwayland`
 - `--cachedir`:  specify custom cache folder
 - `--homedir`: specify host folder to share as home
 - `--trusted`: enforce trusted cookies for `--hostdisplay` and `--kwin-native`
 - `--user` to set user to use (name or uid, non-existing uids possible. default: host user)
 - `--cap-default`: Allow docker default capabilities
### Changed
 - avoid Terminal window with `--no-password`
 - `--orphaned` cleans /tmp/x11docker
 - `--env`: regard whitespaces, use \n to divide entrys
 - set `mode=preferred` for Weston on tty, ignore $Screensize
 - extension `XINERAMA` disabled as multiple Xephyr outputs cannot handle it well
 - create container home folder `/tmp/fakehome` in x11docker_CMD (avoids ownership problems with wine, and is less messy in /tmp)
 - more failure checks in `installer()`
 - check for `--userns-remap`, disabling it with `--userns=host` if `--home` or `--homedir` are set
 - minor exploit check for DISPLAY XAUTHORITY XDG_RUNTIME_DIR WAYLAND_DISPLAY HOME
 - automatically choose trusted or untrusted cookies
 - show docker log in xtermrc if pulling image
 - `docker run `--cap-drop=`ALL` as default

 - `--gpu`: only share `--device=/dev/dri` instead of listing all files in it
### Deprecated
 - `--cache`
### Removed
 - `--hostuser`: effect of `--hostuser` is default now
 - `--sudouser`: not possible anymore due to `--cap-drop=ALL`
### Fixed
