## amcl

```
* Bug fix to remove particle weights being reset when motion model is updated
* Integrated new sensor model which calculates the observation likelihood in a probabilistic manner
  Also includes the option to do beam-skipping (to better handle observations from dynamic obstacles)
* Pose pulled from parameter server when new map received
* Contributors: Steven Kordell, hes3pal
```

## base_local_planner

```
* Bugfix uninitialised occ_cost variable usage
  This fixes #256 <https://github.com/ros-planning/navigation/issues/256>.
* base_local_planner: adds waitForTransform
* Fixed issue causing trajectory planner returning false to isGoalReach ed even when it's control thread finishes executing
* Contributors: Daniel Stonier, Marcus Liebhardt, hes3pal
