Released on September 14th, 2007 (revision 518)

Warning about the Joint node and the "joint" field. In this version, the Joint node and the "joint" fields were completely removed in order to simplify the design of new robot models. The usage of the Joint node was found to be confusing, because it was often unclear if a Joint node was required or not. This version of Webots makes the appropriate decision automatically. In addition, all the instances of Joint nodes were removed from all the .wtb example in Webots distribution. When this version of Webots loads a .wbt file that contain Joint nodes it issues a error message similar to this:

Error at line 979:
Unsupported field: 'joint' for 'Servo' node
You can safely ignore these error messages: then when you subsequently save the .wbt file, Webots automatically removes all the Joint nodes. Therefore there will be no error message the next time you load the .wbt file.

Change in the Shrimp model. The "shrimp.wbt" model was slightly modified as a consequence of the removal of the Joint node. In the previous "shrimp.wbt" model, an empty "joint" field in a Solid node used to indicate that this joint was going to be created in the physics plugin. Now the same thing is indicated by a Servo node which "type" field constains the string "none".

Webots 5.4.0

Released on July 18th, 2007 (revision 369)

Warning about WorldInfo.basicTimeStep. In this version, Webots checks that the controller step (the value passed to robot_step() or returned by the controller's run() function) is a multiple of the basicTimeStep. Simulations that do not meet this requirement will issue warning messages.

Warning about servo_set_force() function. In this version, the existing servo_set_force() function was renamed servo_set_motor_force(). There is now a new servo_set_force() function with a different purpose, please refer to the Reference Manual for more info. We recommend to replace any previous call to servo_set_force() by a call to servo_set_motor_force() in your controller code.

Webots 5.3.1

Released on June 22nd, 2007 for Mac OS X only (revision 283)

Webots 5.3.0

Released on June 21st, 2007 (revision 268)

Webots 5.2.0

Released on June 6th, 2007 (revision 170)

Webots 5.1.14

Released on May 21st, 2007 (revision 99)

Warning about LightSensors The lookupTable of LightSensor sometimes returned incorrect values in previous versions of Webots. This problem was fixed with this new release. As a consequence the light_sensor_get_value() function might in some situation return values different than before, therefore simulations tuned for specific return values will need to be slightly adapted to work with this version.

Webots 5.1.13

Released on May 9th, 2007 (revision 69)

Warning about TouchSensors If TouchSensors were used, existing robot models developed for previous releases of Webots may have to be slightly modified in order to work with this new version of Webots. The new "force" TouchSensors are unidirectional while the old ones were omnidirectional. The new "force" sensors measure the force along their z-axis, while the other axes are ignored. The modification is very simple: the TouchSensors must be reoriented such that their positive z-axes point from the body outwards, in the direction where the force need to be measured (where the collision is expected to take place). Please also note that the values returned by "bumper" sensors may also differ from those of previous Webots version because the new version returns fixed 0 or 1 while the previous version used to return the min or max values of the lookup table.

Webots 5.1.4

Released on March, 28th, 2006 (revision 248)

Warning: This release is not fully upward compatible with Webots 5.1.2. The change is very minor though: if your world files have Servo nodes with an acceleration field different from -1, you should multiply it by 10^6 or set it to -1 (for infinity).

Webots 5.1.3

Released on March 21st, 2006 (revision 205)

Webots 5.1.2

Released on March 7th, 2006 (revision 138)

Webots 5.1.0

Released on December 23th, 2005

Warning: This release is not fully upward compatible with Webots 5.0.10. The change is very minor though: if your world files have Servo nodes with a rotation angle different from 0, you should set it to 0 and add a Servo.position field which contains the value of this angle. Also, the physics and fast2d directories moved into a plugins directory.
