0.5.0 (2010-01-18)

hokuyo_node

• Merged two of the diagnostic statuses that were being reported. Now there are only two, which is less confusing.
• Frequency diagnostics get reset in more cases; should result in fewer spurious low frequency warnings.
• Message cleanup. Should now display a message each time an error arises, and each time it recovers.
• Helpful error messages. Should now give a better idea of what is wrong, and point you at the Troubleshooting page.
• Made reads non-blocking so to avoid race conditions upon concurrent access to the port by a misbehaving process.
• Documentation review completed.
• Made the laser reset procedure robust in the case where the laser is still streaming data.

0.4.1 (2010-01-14)

* hokuyo_node: Changed getID so it retries for at least 10 seconds before giving up. This is necessary as the hokuyo takes a while after being plugged in before it is ready to accept commands.

• hokuyo_node: Fixed a bug that would lock up the driver on certain reconfigure events.

0.4.0 (2010-01-14)

hokuyo_node

• Took out a race condition from the port locking code.
• Made allowable angle range be [-pi:pi].
• Added error checking for out-of-range angles.
• Detects if intensity mode is supported and automatically turns it off if it is not supported.
• Reports firmware version, version name, product name, and protocol version in diagnostics.
• Increased character limit on exception messages.
• Fixed the initialization sequence to properly handle a laser that is scanning.

0.3.0 (2010-01-11)

• Adjusted messages so that the driver will not spew messages when it manages to open a device but fails to get all the way running.
• Updated licenses and package/stack descriptions.
• Removed the node description from doxygen.

0.2.0 (2009-12-23)

• First stable release
