0.6.1 (2009-12-21)

Patch release for gcc 4.4 compatibility.

0.6.0 (2009-12-15)

image_transport:

• Subscriber attempts to recognize and warn when the user passes in a transport-specific topic instead of the base topic.

• ImageTransport constructor from NodeHandle is now explicit.

• SubscriberFilter takes an ImageTransport argument in constructor and subscribe(). Old versions with a NodeHandle argument are deprecated.

• (Camera)Publisher and (Camera)Subscriber methods now mimic roscpp behavior when the object is "invalid" (default-constructed or shutdown).

• Publisher plugin parameter lookup correctly starts in the namespace defined by the base topic.

camera_calibration_parsers:

• Added stream-based read/write functions for INI and YML representations.

0.5.2 (2009-11-03)

image_transport:

• Fixed bug in connection callbacks that sometimes caused a segfault.
• Publisher now throws if it fails to load any plugins.

• Got rid of deprecation warning from getSubscriberCallerID().

camera_calibration_parsers:

• Fix for gcc 4.4.

0.5.1 (2009-10-08)

image_transport:

• Made determination of camera info topic more robust.

• Tweaked output from list_transports.

0.5.0 (2009-10-07)

Stack passed doc review.

image_transport:

• Removed all deprecated functions and classes.

• Fixed compilation bugs in ImageTransport::subscribeCamera().

• Improved output from list_transports.

camera_calibration_parsers:

• Removed deprecated functions.

0.4.0 (2009-10-06)

image_transport:

• Clarified expected lookup behavior for plugin parameters. Involved minor changes to low-level plugin APIs.

0.3.1 (2009-10-05)

Patch release for common's renaming of yaml-cpp to yaml_cpp.

Minor cleanup and doc improvements based on ongoing doc review.

0.3.0 (2009-09-30)

image_transport:

• Fixed bug in SimplePublisherPlugin making it unusable for non-trivial transports

• Added internal subscription callback support to SimplePublisherPlugin

• Parts of the documentation have been moved to the wiki

0.2.1 (2009-09-28)

Patch release to use new pluginlib exceptions.

image_transport and camera_calibration_parsers both API cleared.

0.2.0 (2009-09-23)

New features

image_transport:

• Renamed Publisher and Subscriber classes.

• ImageTransport class for advertising and subscribing to image topics. Provides analogous interface to NodeHandle.

• Transport used determined by hint to Subscriber instead of a per-topic parameter. Besides being a cleaner model, this allows bag files to work correctly with non-raw transports.

• Full subscriber status callback support in publisher classes.

• SubscriberFilter for using image subscriptions with message_filters.

• CameraPublisher and CameraSubscriber convenience classes for managing synchronized Image & CameraInfo topics.

• 'list_transports' utility for checking available transports and troubleshooting
• 'republish' utility node for common tasks:
  • Interfacing compressed transports with Python or legacy C++ nodes
  • Limiting bandwidth and computation on an offboard computer

• SimplePublisherPlugin and SimpleSubscriberPlugin greatly simplify implementing your own transport in most cases.

camera_calibration_parsers:

• New simplified overloads using CameraInfo instead of separate parameter args.

Deprecated

All deprecated features will be removed in 0.3.

image_transport:

• ImagePublisher and ImageSubscriber. Use Publisher and Subscriber instead.

• Parts of the PublisherPlugin and SubscriberPlugin have changed, but remain in deprecated form for backwards compatibility.

camera_calibration_parsers:

• Functions with separate parameter args have been deprecated in favor of the CameraInfo versions.

Removed

image_transport:

• transform node. Replaced by republish.

Backwards compatibility

image_transport is largely backwards compatible with 0.1:

• Images published by Publisher can be received by ImageSubscriber

• Images published by ImagePublisher can be received by Subscriber

• Existing plugins will continue to work with ImagePublisher and ImageSubscriber. However, they will need to be upgraded to work with the new Publisher and Subscriber.

camera_calibration_parsers is fully backwards compatible.
