 .
   [ Mihai Moldovan ]
   * New upstream version (4.1.1.0):
     - src/sshmasterconnection.cpp: use ssh_channel_listen_forward () instead
       of ssh_forward_listen () for newer libssh versions. Fixes: #870.
     - src/sshmasterconnection.cpp: with libssh 0.6.0 and newer, get the public
       key via ssh_get_server_publickey () (0.8.0 and higher) or
       ssh_get_publickey () (0.7.x and lower) and its hash via
       ssh_get_publickey_hash () instead of using the deprecated
       ssh_get_pubkey_hash () function. Additionally, replace free () with the
       more appropriate ssh_string_free_char () function after using
       ssh_get_hexa (). This will break on very old systems with a hopelessly
       outdated libssh version, but we do not care about these systems in the
       first place.
     - src/sshmasterconnection.cpp: replace string_free () with its successor
       ssh_string_free (). Will break on ancient systems, but we don't care.
     - src/sshmasterconnection.cpp: replace deprecated channel_new () function
       with ssh_channel_new (). Might break on ancient systems, but we don't
       care. Also, add error handling in case ssh_channel_new () failed...
     - src/sshmasterconnection.cpp: replace deprecated channel_open_forward ()
       function with ssh_channel_open_forward (). Might break on ancient
       systems, but we don't care.
     - src/sshmasterconnection.cpp: replace deprecated channel_open_session ()
       function with ssh_channel_open_session (). Might break on ancient
       systems, but we don't care.
     - src/sshmasterconnection.cpp: replace deprecated channel_request_exec ()
       function with ssh_channel_request_exec (). Might break on ancient
       systems, but we don't care.
     - src/sshmasterconnection.cpp: replace deprecated channel_poll () function
       with ssh_channel_poll (). Might break on ancient systems, but we don't
       care.
     - src/sshmasterconnection.cpp: replace deprecated channel_read () function
       with ssh_channel_read (). Might break on ancient systems, but we don't
       care.
     - src/sshmasterconnection.cpp: replace deprecated channel_is_eof ()
       function with ssh_channel_is_eof (). Might break on ancient systems, but
       we don't care.
     - src/sshmasterconnection.cpp: replace deprecated channel_write ()
       function with ssh_channel_write (). Might break on ancient systems, but
       we don't care.
     - src/sshmasterconnection.cpp: replace deprecated channel_send_eof ()
       function with ssh_channel_send_eof (). Might break on ancient systems,
       but we don't care.
     - src/sshmasterconnection.cpp: replace deprecated channel_close ()
       function with ssh_channel_close (). Might break on ancient systems, but
       we don't care.
     - src/sshmasterconnection.cpp: replace deprecated channel_free () function
       with ssh_channel_free (). Might break on ancient systems, but we don't
       care.
     - src/sshmasterconnection.cpp: use QString::arg () to insert function name
       and thus deduplicate error translation messages. Also re-add the full
       stop sign and remove it when needed for x2goDebug.
     - src/sshmasterconnection.cpp: fix up some debug strings.
     - src/sshmasterconnection.cpp: port more occurrences of "QString to C
       string" akin to 1b21d75f2c10609f3586f5b5e0b4ceb7fca83fdd.
     - src/sshmasterconnection.cpp: enable parsing of ~/.ssh/config.
       Fixes: #1121. Shorthands as host names and other bells and whistles like
       inferred port or user name values are now supported.
     - src/{onmainwindow,httpbrokerclient}.cpp: fix up error/warning message
       displayed when the server-specified key is unknown, but we have another
       key type stored already.
     - src/pulsemanager.cpp: fix up a debug string. Qt drops a space where I'd
       like to have one and inserts a space where I'd like none, so work around
       that fancifully.
     - src/sshmasterconnection.cpp: libssh < 0.6.0 does not have the
       ssh_options_get () API, but instead expects users to pull out
       information directly from the ssh_session structure. This fixes compile
       issues on systems with older libssh versions.
     - src/sshmasterconnection.cpp: turns out libssh < 0.6.0 doesn't support
       fetching the host, port and username parameters at all. We're in the
       clear for non-SSH-proxied connections and can use config file parsing,
       but have to disable config file parsing in the proxy settings, as
       there's no way to query the remote endpoint information. As a result we
       will be unable to open a new socket to the remote endpoint and proxying
       will fail badly.
     - src/x2goutils.cpp: ensure that add_to_path () also processes the first
       value passed. Fixes startup problems in MacPorts. Fixes: #1093.
     - res/i18n/x2goclient_et.ts: various fixups for the Estonian translation
       file.
     - res/i18n/x2goclient_*.ts: go the extra mile and fix up translation files
       manually after the "anothertype" fix in
       8e503d89ee2d03a313c3deff11f0516fce503022.
     - {src/{onmainwindow,httpbrokerclient}.cpp,res/i18n/x2goclient_*.ts}: fix
       another occurrence of a string missing a space separator between words
       and update translation files.
     - src/onmainwindow.cpp: don't duplicate depth warning message needlessly,
       use correct plural forms in translations and split string up in a
       translation-friendly form. I'll leave translators to handle this beast,
       as languages are unique in the number of plural forms and the like.
     - {src/printdialog.cpp,res/i18n/x2goclient_*.ts}: drop spurious left-over
       parenthesis in warning message and adapt translations.
     - src/onmainwindow.cpp: make the "not loading translator" message
       non-translatable, as it doesn't make a lot of sense to actually
       translate it.
     - {src/{configdialog,x2goutils}.cpp,res/i18n/x2goclient_*.ts}: change
       XQuartz project homepage references, adapt translations.
     - src/pulsemanager.{cpp,h}: make get_* () functions const.
     - src/pulsemanager.{cpp,h}: make is_server_running () const.
     - src/pulsemanager.{cpp,h}: add new pulse_version_valid_ boolean class
       member variable, set it correctly and use it whenever the version is
       accessed.
     - src/pulsemanager.cpp: make fetch_pulseaudio_version () more resilient.
       Instead of aborting hard when the version number could not be detected,
       break out of the loops only. We can make stuff work, even if the version
       is unknown. Or just continue without PA support as such.
     - src/pulsemanager.{cpp,h}: add show_startup_warning () for both PA server
       and (debug) startup sound playback.
     - src/pulsemanager.cpp: check server_binary_ before using it and jump over
       code that assumes the PA server binary to be available.
     - src/pulsemanager.cpp: don't fail hard on OS X if the PA server binary
       could not be found in the constructor. We can live without PA and will
       show a warning message to the user later on when PA is supposed to be
       started.
     - src/pulsemanager.cpp: deduplicate warning/error messages - make use of
       show_startup_warning (). This does imply changes to the translation
       files, coming up next.
     - res/i18n/x2goclient_*.ts: regenerate translation files and fix up some
       SSH and PulseManager messages manually, where possible.
     - src/x2ogutils.h: guard UNUSED macro definition.
     - {macbuild.sh,src/{x2goutils.h,{pulsemanager,onmainwindow}.cpp},
        x2goclient.pro}: make MacPorts prefix selectable at compile time. Much
       cleaner for downstream package maintainers (like, for instance, MacPorts
       itself.)
     - res/i18n/x2goclient_fi.ts: remove outdated comment.
     - src/sshprocess.cpp: bind direct tunnel socket to localhost instead of
       any address. Fixes: #31.
     - src/onmainwindow.cpp: check for sessionExplorer->getLastSession() to be
       valid in all places but obvious ones. Fixes: #499.
     - src/sshmasterconnection.cpp: use new PKI-based libssh API for public key
       authentication for libssh 0.6.0 and higher. Fixes: #1119.
     - src/sshmasterconnection.cpp: add YubiKey challenge auth prompt.
     - src/sshmasterconnection.cpp: fix compile errors on pre-libssh-0.6.0
       systems and add a TOCTU-race check to see if the file exists prior to
       calling privatekey_from_file () on such systems. Additionally fix a type
       issue.
     - macbuild.sh: fix long-standing issue that made the DMG bundle contain a
       symlink made up of only a space to /Applications.
     - res/img/icons/dmg: add new image disk.svg, used as the basis for the new
       OS X DMG bundle icon.
     - res/img/icons/dmg: add new disk-drive-and-x2goclient icon for use as the
       volume icon of the OS X DMG bundle.
     - macbuild.sh: use the new volume icon that actually also looks like a
       disk drive. Fixes: #930.
     - src/onmainwindow.cpp: typo fix only.
     - src/onmainwindow.cpp: do not automatically set login user name to
       current system user if empty. Unbreaks default user name fetching via
       libssh. Might break some use cases (especially RDP, XDMCP).
     - src/x2goclient.cpp: revert change bypassing the UNIX cleanup helper.
     - src/onmainwindow.cpp: revert old behavior and select user name field
       after a session has been suspended/terminated if user name was not
       provided. Do not insert an user name, though, but leave it to
       autodetection by default.
     - src/sshmasterconnection.cpp: fix SSH-proxied connections with port
       numbers of zero.
       In order to authenticate the remote server, SSH-proxied connections must
       be reset to their remote host and port values after connecting via the
       SSH tunnel. If the original port value was zero, setting it was skipped,
       leading to connections like $REMOTE_HOST:$PROXY_PORT, which is certainly
       wrong. Fetch the inferred port value and set this instead, fixing this
       issue.
     - Makefile: add new QMAKE_OPTS variable so that packagers can pass
       additional options to qmake directly.
     - src/sshmasterconnection.cpp: typo fix in log message only.
     - src/sshmasterconnection.cpp: don't leak ssh_session data, free it once
       we're done with it.
     - Makefile: qmake seems to act weird if QMAKE_C(XX)FLAGS starts with a
       space followed by additional non-whitespace characters. Refactor the
       variables a bit to work around this issue.
     - Makefile: turns out the only somewhat portable way to do something like
       this is via shell hackery.
     - Makefile: reset to the original state and make sure that we don't pass
       CXXFLAGS on to the actual build process to not override the values
       generated by qmake.
     - Makefile: the only way to prevent variables on the command line to be
       passed down seems to be to remove them from MAKEOVERRIDES.
       .MAKEOVERRIDES is the FreeBSD-make-equivalent variable. MAKEFLAGS has no
       effect on this behavior, so removing it again.
     - Makefile: add comment explaining why we need to do this in the first
       place and why it's so complicated.
     - src/sshmasterconnection: ignore "garbage", but require at least one line
       to start with a known challenge auth prompt. Fixes: #966.
     - x2goclient.pro: add libssh_threads library. We need this since X2Go
       Client is multi-threaded.
     - copy-deps-win32.bat: also copy libssh_threads.dll to go with the
       previous change.
     - src/{onmainwindow,sshmasterconnection}.{cpp,h}: correctly initialize and
       finalize libssh. We ought to do both only once - in our main thread.
       Previously, we initialized libssh in a new thread, which might be
       problematic.
     - src/sessionexplorer.cpp: open the correct tab when editing a session
       from the exports menu.
     - src/onmainwindow.cpp: try to workaround window placement if settings
       contain a (newly) invalid position (e.g., a position that refers to a
       disconnected display.)
     - src/onmainwindow.cpp: try to find a display that can hold the window's
       position fetched from the sizes settings. Use the default if none could
       be found.
     - src/onmainwindow.cpp: fix up main window position check; use
       QRect.intersects ().
     - src/pulsemanager.{cpp,h}: rename shutdownState to shutdown_state_,
       reorder in initializer list.
     - res/i18n/: regenerate translations.
     - res/i18n/x2goclient_es.ts: fixup Spanish translation file.
     - res/i18n/x2goclient_et.ts: fixup some typos in the Estonian translation
       file.
     - res/i18n/x2goclient_sv.ts: add singular form to translation entry as
       discussed on list.
     - res/i18n/x2goclient_es.ts: add singular form to translation entry as
       discussed off list.
     - res/i18n/x2goclient_nl.ts: various fixups for Dutch translation file.
     - res/i18n/x2goclient_nb_no.ts: various fixups for Bokmål (Norway)
       translation file.
     - res/i18n/x2goclient_nl.ts: fix whitespace issues in Dutch translation
       file and re-add numerus form translation.
     - res/i18n/x2goclient_nb_no.ts: various fixups for Bokmål (Norway)
       translation file, including numerus form.
     - src/sshmasterconnection.cpp: for proxied connections, fetch the user
       name matching the given host, not proxy host.
     - res/i18n/x2goclient_fi.ts: various fixups for Finnish translation file.
     - res/i18n/x2goclient_fi.ts: another tiny whitespace fixup for Finnish
       translation file.
     - src/onmainwindow.cpp: fix "XMDCP" typo.
     - res/i18n/x2goclient_de.ts: various fixups for German translation file.
     - src/onmainwindow.cpp: fix "loose" vs. "lose" spelling mistake.
     - res/i18n/x2goclient_et.ts: remove obsolete and wrongly capitalized
       "x2go" part from an Estonian translation message.
     - res/i18n/x2goclient_sv.ts: minor whitespace fixup.
     - res/i18n/x2goclient_*.ts: apply "XMDCP" -> "XDMCP" fix manually to
       translation files.
     - res/i18n/x2goclient_nb_no.ts: remove obsolete comments (leading to
       problems when regenerating translation files.)

       when regenerating translation files.)
     - res/i18n/x2goclient_*.ts: regenerate translations.
     - res/i18n/x2goclient_fi.ts: various fixups for Finnish translation file.
     - src/sshmasterconnection.cpp: spelling fix. (Quiting -> Quitting)
     - x2gobrowserplugin-2.4_1/src/qtbrowserplugin.cpp: spelling fix.
       (convertable -> convertible)
   * x2goclient.spec:
     - Respect %{optflags} and pass QMAKE_STRIP=: to fix missing debug info
       issues.
 .
   [ Oleksandr Shneyder ]
   * New upstream version (4.1.1.0):
     - Interaction with SSH server (for example for changing
       expired password). Fixes: #592.
     - Fixing setting widget style issue in InteractionDialog on
       Windows client.
     - SSH Interaction for SSH Broker and SSH Server.
     - SSH Iteraction for method keyboard-interactive.
     - Move PulseManager MsgBox functions to main window:
       GUI functions should be used only from main thread.
     - Check "norecord" option on the first start of PulseAudio.
     - Disable/Enable PulseAudio in config dialog.
       New command line options:
       --disable-pulse to disable start of PulseAudio
       --disable-pulse-record to disable audio input.
     - Check if PulseAudio running at session start and resuming
       when sound is enabled. Show warning if PulseAudio not running
       and disable the sound support for the session to avoid
       session freezes.
     - Add session config file option "sshproxysamekey". With this option
       client will use for proxy authentication same key as for X2Go server.
       This is important in first case for broker users, where key can be
       generated "on the fly". Maybe it makes sence to add this option in UI
       and command line later.
     - Correct negative display coordinates for FS sessions.
