Version 2.4.0

Enhancements

• info sorts property names
• Added UCA_CAMERA_ERROR_DEVICE for device-specific errors which are not covered
  by specific error codes
• errors are printed on stderr
• meson does not require gtk
• added uca_camera_stopped_recording to report that recording was cancelled
• properly initialize Python 3
• recording state policy finalized (#44 after almost 8 years 🎆)
  • use real device state in the properties and respective functions
  • use cached device state in grab and trigger
  • synchronize camera state on construction
• meson: add with_python_multithreading option

Fixes

• minor memory leaks
• avoid eternal spin-lock if thread ends with error
• fix error on dispose

Version 2.3.0

Enhancements

• Besides CMake we now also support meson
• mock: provide setter/getter for test-enum
• mock: add a custom enum type for test purposes
• mock: receive SIGUSR1 to simulate external trigger
• grab: measure time per frame grab
• grab: allow filename to be a format specifier
• grab: show progress during acquisition
• gui: use glib-resources to bake in UI

Fixes

• Parse enum properties properly
• Stop construction and exit early on error

Breaks and changes

• Raise minimum GLib version to 2.38
• Abort construction if props cannot be parsed
• grab: drop --write-tiff and guess from file suffix
• grab: drop support for --duration
• grab: do not write at all if --output is not given

Version 2.2.1

Enhancements:

• Replace our homegrown install path system with CMake's GNUInstallDirs
• Use better system to parse command line argument properties for the command
  line tools.

Fixes:

• Fix #80: trigger must not block on the access_lock.
• Emulate correct software trigger behaviour for the mock camera.

Version 2.2.0

Enhancements:

• Improve Windows support
• Add uca-info tool to print current prop values
• Add debug output of plugin module location
• Add stress test script for TANGO
• Increase maximum dimension of TANGO image attribute
• cli: pass -p/--property assignment to constructor
• Improve benchmark output and count the number of dropped frames

Fixes:

• Fix #69, #71, #72, #74
• Fix segfaults with changing ROI or bitdepth
• Fix zoom problems and statistics in the GUI
• Fix reading of 32 bit TIFFs in file plugin
• Allow setting max bin value of histogram

Breaks and changes:

• Raise GLib dependency to 2.28
• Do not stop camera when closing the object
• Move sensor binnings array out to plugin and remove it from mock
• mock: replace create-random with fill-data policy

Version 2.1.1

This is bugfix release:

• pco: use Fg_stopAcquire in stop_readout
• Fix #72: avoid race condition in GUI
• Fix ufo-kit/concert#373: use same unit for ROI and ROI multiplier

Version 2.1

This is a combined bug fix and feature release. Most notably there is a new uca_camera_readout() API to grab arbitrary frames from cameras with in-camera memory, e.g. the pco.dimax.

• pco: fix deadlock with streamed acquisition
• pco: allocate memory also when just reading out
• pco: do not reset storage mode
• file: signal change of ROI and bitdepth and read complete filename path
• ufo: update trigger policy
• dexela: Correct the ROI dimensions respecting the binning mode
• dexela: only allow symmetricall binnings
• pylon and dexela: update to the new trigger API
• Add FindClserSis to find the frame grabber SDK
• sensor-width, sensor-height and sensor-bitdepth are not construct-only anymore

Version 2.0

This release changes the trigger properties from a single "trigger-type" property to separate "trigger-source" and "trigger-type" properties. Apart from that numerous bug fixes and the following updates have been done since 1.6.2:

• uca-benchmark measures more mode combinations.
• A basic Python-based TANGO server has been added.
• pco: Check for SiliconSoftware run-time version 5.2.2.
• Add uca_camera_write to "write" arbitrary data to the camera. The semantics
  are camera-specific.
• Added uca_plugin_manager_get_camerah to pass property values via a GHashTable.
• The plugin directory can be queried via pkg-config.
• The Python GIL is released on potentially long-running code paths.

Version 1.6.2

This bugfix release solves a regression introduced with libuca 1.6.0 and
documented in issue #61.

Version 1.6.1

This is a bugfix release smoothing out daily operation. In particular, we

• release the Python GIL to avoid blocking on grabs
• added missing property specification for exposure-auto in the pylon plugin
• improved robustness of ROI setting in the pylon plugin
• added global shutter support for pco.edge cameras

Version 1.6

This is mainly a cleanup and bugfix release with the following major updates:

• Updated and fixed the Dexela plugin (v1.3.2).
• Fixed a race condition for buffered acquisition.
• Added version property to pco cameras.
• Reset all property units and warn on override

API changes

• Removed "sensor-max-frame-rate" property.
• Remove unused virtual record_ functions.
• Added uca_camera_set_writable and uca_camera_is_writable_during_acquisition.
