  Signed-off-by: Shane Loretz <sloretz@osrfoundation.org>
* Fix compile error missing ros/ros.h (`#400 <https://github.com/ros/geometry2/issues/400>`_)
  * ros/ros.h -> ros/time.h
  tf2 package depends on rostime
  * tf2_bullet doesn't need ros.h
  Signed-off-by: Shane Loretz <sloretz@osrfoundation.org>
  * tf2_eigen doesn't need ros/ros.h
  Signed-off-by: Shane Loretz <sloretz@osrfoundation.org>
* Merge pull request `#367 <https://github.com/ros/geometry2/issues/367>`_ from kejxu/add_tf2_namespace_to_avoid_name_collision
  rework Eigen functions namespace hack

  * use ROS_DEPRECATED for better portability
  * change ROS_DEPRECATED position (`#5 <https://github.com/ros/geometry2/issues/5>`_)
* Remove `signals` from find_package(Boost COMPONENTS ...).
  tf2 is using signals2, which is not the same library.
  Additionally, signals2 has always been header only, and header only
  libraries must not be listed in find_package.
  Boost 1.69 removed the old signals library entirely, so the otherwise
  useless `COMPONENTS signals` actually breaks the build.
* Remove legacy inclusion in CMakeLists of tf2.

* tf2: add missing console bridge include directories (fix `#48 <https://github.com/ros/geometry_experimental/issues/48>`_)

* Contributors: Dirk Thomas, Timo Rohling, Tully Foote

0.4.9 (2013-11-06)
------------------

0.4.8 (2013-11-06)
------------------
* moving python documentation to tf2_ros from tf2 to follow the code
* removing legacy rospy dependency. implementation removed in 0.4.0 fixes `#27 <https://github.com/ros/geometry_experimental/issues/27>`_

0.4.7 (2013-08-28)

* switching to use allFramesAsStringNoLock inside of getLatestCommonTime and walkToParent and locking in public API _getLatestCommonTime instead re `#23 <https://github.com/ros/geometry_experimental/issues/23>`_
* Fixes a crash in tf's view_frames related to dot code generation in allFramesAsDot

0.4.6 (2013-08-28)
------------------

* adding _allFramesAsDot for backwards compatability https://github.com/ros/geometry/issues/18

0.4.4 (2013-07-09)
------------------
* making repo use CATKIN_ENABLE_TESTING correctly and switching rostest to be a test_depend with that change.
* tf2: Fixes a warning on OS X, but generally safer
  Replaces the use of pointers with shared_ptrs,
  this allows the polymorphism and makes it so that
  the compiler doesn't yell at us about calling
  delete on a class with a public non-virtual
  destructor.
* tf2: Fixes compiler warnings on OS X
  This exploited a gcc specific extension and is not
  C++ standard compliant. There used to be a "fix"
  for OS X which no longer applies. I think it is ok
  to use this as an int instead of a double, but
  another way to fix it would be to use a define.
* tf2: Fixes linkedit errors on OS X

0.4.3 (2013-07-05)
------------------

0.4.2 (2013-07-05)
------------------
* adding getCacheLength() to parallel old tf API
* removing legacy static const variable MAX_EXTRAPOLATION_DISTANCE copied from tf unnecessesarily

0.4.1 (2013-07-05)
------------------
* adding old style callback notifications to BufferCore to enable backwards compatability of message filters
* exposing dedicated thread logic in BufferCore and checking in Buffer
* more methods to expose, and check for empty cache before getting latest timestamp
* adding methods to enable backwards compatability for passing through to tf::Transformer

0.4.0 (2013-06-27)
------------------
* splitting rospy dependency into tf2_py so tf2 is pure c++ library.
* switching to console_bridge from rosconsole
* moving convert methods back into tf2 because it does not have any ros dependencies beyond ros::Time which is already a dependency of tf2
* Cleaning up unnecessary dependency on roscpp
* Cleaning up packaging of tf2 including:
  removing unused nodehandle
  fixing overmatch on search and replace
  cleaning up a few dependencies and linking
  removing old backup of package.xml
  making diff minimally different from tf version of library
* suppressing bullet LinearMath copy inside of tf2, so it will not collide, and should not be used externally.
* Restoring test packages and bullet packages.
  reverting 3570e8c42f9b394ecbfd9db076b920b41300ad55 to get back more of the packages previously implemented
  reverting 04cf29d1b58c660fdc999ab83563a5d4b76ab331 to fix `#7 <https://github.com/ros/geometry_experimental/issues/7>`_
* fixing includes in unit tests
* Make PythonLibs find_package python2 specific
  On systems with python 3 installed and default, find_package(PythonLibs) will find the python 3 paths and libraries. However, the c++ include structure seems to be different in python 3 and tf2 uses includes that are no longer present or deprecated.
  Until the includes are made to be python 3 compliant, we should specify that the version of python found must be python 2.

* Josh change: fix first/last time case. 46bf33868e0d
* fix transform accumulation to parent
* fix parent lookup, now works on the real pr2's tree
* move the message filter to tf2_ros
* tf2::MessageFilter + tests.  Still need to change it around to pass in a callback queue, since we're being triggered directly from the tf2 buffer
* Don't add the request if the transform is already available.  Add some new tests
* working transformable callbacks with a simple (incomplete) test case
* first pass at a transformable callback api, not tested yet
* add interpolation cases
* fix getLatestCommonTime -- no longer returns the latest of any of the times
* Some more optimization -- allow findClosest to inline
* another minor speedup

* Add explicit operator= so that we can see the time in it on a profile graph.  Also some minor cleanup
* minor cleanup
* add 3 more cases to the speed test
* Remove use of btTransform at all from transform accumulation, since the conversion to/from is unnecessary, expensive, and can introduce floating point error

* Completely remove lookupLists().  canTransform() now uses the same walking code as lookupTransform().  Also fixed a bug in the static transform publisher test

* Some more optimization:
  * Reduce # of TransformStorage copies made in TimeCache::getData()
  * Remove use of lookupLists from getLatestCommonTime

* Update cache unit tests to work with the changes TransformStorage.
  Also make sure that BT_USE_DOUBLE_PRECISION is set for tf2.

  Also fixed a number of thread-safety problems
* Optimize test_extrapolation a bit, 25% speedup of lookupTransform
* use a hash map for looking up frame numbers, speeds up lookupTransform by ~8%
* Cache vectors used for looking up transforms.  Speeds up lookupTransform by another 10%
* speed up lookupTransform by another 25%
