v23.0

New Features in 23.0

• Python 3.6 support has been dropped.
• Exporter config templates now have access to the following new variables:
  isolated (all resource accesses must be tunneled True/False),
  hostname (of the exporter host), name (of the exporter).
• ModbusRTU driver for instruments
• Support for Eaton ePDU and TP-Link power strips added, either can be used as
  a NetworkPowerPort.
• The example strategies now wait for complete system startup using systemctl.
• Consider a combination of multiple "lg_feature" markers instead of
  considering only the closest marker.
• There is a new get_strategy helper function which returns the strategy of
  the target.
• labgrid-client now supports an export command which exposes the resource
  information as environment variables.
• Newer C920 webcams are now supported.
• The pytestplugin now correctly combines feature markers instead of replacing
  them.
• The ConsoleLoggingReporter is now exported for library usage.
• The HD 2MP Webcam is now supported by the video-driver.
• TP-Link power strips are supported by the NetworkPowerDriver.
• A ModbusRTUResource and Driver has been added to control RS485 equipment.
• The strategies within labgrid learned the force() function.
• The labgrid client SSH command is now able to instantiate the SSHDriver when
  there are multiple NetworkService resources available.
• eg_pms2_network power port driver supports controlling the Energenie power
  management series with devices like the EG_PMS2_LAN & EG_PMS2_WLAN.
• The client and coordinator learned of a new "release-from" operation that
  only releases a place if it acquired by a specific user. This can be used to
  prevent race conditions when attempting to automate the cleanup of unused
  places (e.g. in CI jobs).
• ModbusTCPCoil driver supports writing using multiple coils write method
  in order to make driver usable with Papouch Quido I/O modules.
• If supported, ser2net started by the exporter now allows multiple connections.
• SmallUBootDriver driver now supports wide range of Ralink/mt7621 devices
  which expects boot_secret without new line with new boot_secret_nolf
  boolean config option.
• More USBVideo devices have been added.
• labgrid now uses a custom yaml loader/dumper.
• labgrid-client add-match/add-named-match check for duplicate matches
• DFUDriver has been added to communicate with a DFUDevice, a device in DFU
  (Device Firmware Upgrade) mode.
• labgrid-client dfu added to allow communication with devices in DFU mode.
• Support for QEMU Q35 machine added.
• UBootDriver now handles idle console, allowing driver activation on
  an interrupted U-Boot.
• Support for the STLINK-V3 has been added to the USBDebugger resource.
• labgrid-suggest can now suggest matches for a USBPowerPort used by power
  switchable USB hubs.
• AndroidFastboot is now deprecated and was replaced by AndroidUSBFastboot. This
  is more consistent with the AndroidNetFastboot support.
• In case multiple matches are found for a driver, labgrid-client now outputs
  the available names.
• ProcessWrapper now supports an "input" argument to check_output() that allows
  a string to be passed to stdin of the process.
• The NetworkInterfaceDriver now supports local and remote SSH port
  forwarding to/from the exporter.
• labgrid was switched over to use pyproject.toml.
• A contrib script was added to export coordinator metrics to stasd.
• The SSH connection timeout can now be globally controlled using the
  LG_SSH_CONNECT_TIMEOUT environment variable.
• The QEMUDriver now supports a display option which can specify if an
  display device should be created. none (the default) will not create a
  display device, fb-headless will create a headless framebuffer device
  for software rendering, and egl-headless will create a headless GPU
  device for accelerated rendering (but requires host support).
• The AndroidFastbootDriver now supports interaction with network devices in
  fastboot state.
• Add bash completion for labgrid-client.
• The QEMUDriver now support a nic property that can be used to create a
  network interface when booting.
• The SSHDriver now correctly uses the processwrapper for rsync.
• The QEMUDriver now supports API to add port-forwarding from localhost.
• The get() method for sdwire has been added.
• If there are multiple named resources for a target, one of them can be named
  "default" to select it automatically if no explicit other name is given.
• labgrid-client has been extended with --name/-n for most commands. This allows
  attaching multiple power sources/usb-muxes and switching them individually
  from the command line.
• Add DediprogFlashDriver and DediprogFlasher resource.
• Add support for Digital Loggers PDU.
• Add support for Shelly power switches.
• Make labgrid-client use crossbar_url and crossbar_realm from ennvironment
  config.

Bug fixes in 23.0

• The exporter now exports sysfsgpios during place acquire/release, fixing a
  race in the sysfspgio agent interface.
• Fixed a bug where using labgrid-client io get always returned low
  when reading a sysfsgpio.
• Fix labgrid-client exit code on keyboard interrupt.
• Fixed labgrid-client forward --remote/-R, which used either the LOCAL
  part of --local/-L accidentally (if specified) or raised an
  UnboundLocalError.
• Fix udev matching by attributes.
• Stop Exporter's event loop when register calls fail.
• Fix exit codes for various subcommands.
• Omit role and place output for labgrid-client reserve to fix shell
  evaluation.

Breaking changes in 23.0

• Config's get_option()/get_target_option() convert non-string
  options no longer to strings.
• UBootDriver's boot_expression attribute is deprecated, it will no
  longer check for the string during U-Boot boot. This allows activating the
  driver on an already running U-Boot.
• The uuu command handling was fixed for the UUUDriver.
• UBootDriver boot() method was fixed.
• Fix proxying of dynamic port power backends with URL in host parameter and
  authentication credentials.
• The coordinator was switched over to anonymous static authentication. You'll
  have to use the legacy crossbar configuration to support older
  clients/exporters. The 23.1 release will remove support for the legacy ticket
  authentication.
• AndroidFastboot has been deprecated. Please replace it with the more specific
  AndroidUSBFastboot with the same semantics.
