v2.3.0
======
What's Changed
--------------
The Isaac Lab 2.3.0 release, built on Isaac Sim 5.1, delivers enhancements across dexterous manipulation,
teleoperation, and learning workflows. It introduces new dexterous environments with advanced training capabilities,
expands surface gripper and teleoperation support for a wider range of robots and devices,
and integrates SkillGen with the Mimic imitation learning pipeline to enable GPU-accelerated motion planning
and skill-based data generation with cuRobo integration.
Key highlights of this release include:
* **Dexterous RL (DexSuite)**: Introduction of two new dexterous manipulation environments using the Kuka arm and
Allegro hand setup, with addition of support for Automatic Domain Randomization (ADR) and PBT (Population-Based Training).
* **Surface gripper updates**: Surface gripper has been extended to support Manager-based workflows,
including the addition of ``SurfaceGripperAction`` and ``SurfaceGripperActionCfg``, along with several new environments
demonstrating teleoperation examples with surface grippers and the RMPFlow controller.
New robots and variations are introduced, including Franka and UR10 with robotiq grippers and suction cups,
and Galbot and Agibot robots.
* **Mimic - SkillGen**: SkillGen support has been added for the Mimic Imitation Learning pipeline,
introducing cuRobo integration, integrating GPU motion planning with skill-segmented data generation.
Note that cuRobo has proprietary licensing terms, please review the
`cuRobo license <https://github.com/isaac-sim/IsaacLab/blob/main/docs/licenses/dependencies/cuRobo-license.txt>`_
carefully before use.
* **Mimic - Locomanipulation**: Added a new G1 humanoid environment combining RL-based locomotion with IK-based
manipulation. A full robot navigation stack is integrated to augment demonstrations with randomization of
tabletop pick/place locations, destination and ground obstacles. By segmenting tasks into pick-navigate-place
phases, this method enables generation of large-scale loco-manipulation datasets from manipulation-only
demonstrations.
* **Teleoperation**: Upper body inverse kinematics controller is improved by adding a null space posture task that
helps enable waist movement on humanoid tasks while regularizing redundant degrees-of-freedom to a preferred
upright posture. Additionally, support for Vive and Manus Glove are introduced, providing more options for
teleoperation devices.

Isaac Sim 5.1 Updates
----------------------
* Introduced support for `DGX Spark <https://www.nvidia.com/en-us/products/workstations/dgx-spark/>`_,
including multi-architecture Docker images with support for ARM platforms.
* PhysX now offers a new joint parameter tuning `tutorial <https://docs.omniverse.nvidia.com/kit/docs/omni_physics/107.3/dev_guide/guides/gripper_tuning_example.html>`_
for robotic grippers, along with a new feature for solving articulation collision contacts last to improve on
gripper penetration issues, especially for cases with sub-optimally tuned joints.
* Surface grippers has been optimized for better performance. Although support continues to be CPU-only,
performance has improved by several orders of magnitude compared to previous releases.
* Windows 10 support ended on October 14, 2025. Microsoft will no longer provide free security, feature, or technical
updates for Windows 10. As a result, we will be dropping support for Windows 10 in future releases of Isaac Sim and Lab
to ensure the security and functionality of our software.

Known Issues
~~~~~~~~~~~~
* The ROS2 docker image is not currently expected to work due to the update to Python 3.11. We are actively working on
a fix to resolve this.
* We have received reports of performance regressions in the previous Isaac Sim release for both physics and rendering
workflows. We are still working on addressing some of these, but have also found some workarounds.
For viewport regressions, Omniverse settings can be set by adding
``--kit_args="--/app/usdrt/hierarchy/partialGpuUpdate=1 --/rtx/post/dlss/execMode=0 --/app/runLoops/main/rateLimitEnabled=false --/app/runLoops/main/manualModeEnabled=true --enable omni.kit.loop-isaac"``. Additionally, Isaac Sim 5.0
introduced new actuator models for PhysX, including drive model and friction model improvements.
These improvements also introduced a small performance regression. We have observed up to ~20% slowdown in some
state-based environments.

v2.1.0
======
Overview
--------
This release introduces the official support for teleoperation using the Apple Vision Pro for collecting high-quality
and dexterous hand data, including the addition of bi-manual teleoperation and imitation learning workflows through Isaac Lab Mimic.
We have also introduced new randomization methods for USD attributes, including the randomization of
scale, color, and textures. In this release, we updated RSL RL to v2.3.1, which introduces many additional features
including distributed training, student-teacher distillation, and recurrent student-teacher distillation.
Additionally, we revamped the `Extension Template <https://github.com/isaac-sim/IsaacLabExtensionTemplate>`_
to include an automatic template generator tool from within the Isaac Lab repo. The extension template is
a powerful method for users to develop new projects in user-hosted repos, allowing for isolation from the core
Isaac Lab repo and changes. The previous IsaacLabExtensionTemplate repo showed a limited example pertaining only
to the Manager-based workflow and RSL RL. In the new template generator, users can choose from any supported
workflow and RL library, along with the desired RL algorithm. We will be deprecating the standalone
`IsaacLabExtensionTemplate <https://github.com/isaac-sim/IsaacLabExtensionTemplate>`_ in the near future.
NVIDIA has also released `HOVER <https://github.com/NVlabs/HOVER>`_ as an independent repo, hosting a neural whole body
controller for humanoids built on top of Isaac Lab. HOVER includes sim-to-real workflows for deployment on the Unitree
H1 robot, which we have also added a tutorial guide for the deployment process in the Isaac Lab documentation.

.. attention::
We strongly recommend reviewing the details to fully understand the change in behavior,
as it may impact the deployment of learned policies. Please open an issue on GitHub if
you face any problems.
Introduction of simulation's effort and velocity limits parameters in ActuatorBaseCfg
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We have introduced the configuration variables :attr:`~isaaclab.actuators.ActuatorBaseCfg.velocity_limit_sim`
and :attr:`~isaaclab.actuators.ActuatorBaseCfg.effort_limit_sim` to the
:class:`isaaclab.actuators.ActuatorBaseCfg` to allow users to set the **simulation** joint velocity
and effort limits through the actuator configuration class.
Previously, we were overusing the attributes :attr:`~isaaclab.actuators.ActuatorBaseCfg.velocity_limit`
and :attr:`~isaaclab.actuators.ActuatorBaseCfg.effort_limit` inside the actuator configuration. A series
of changes in-between led to a regression from v1.4.0 to v2.0.1 release of IsaacLab. To make this
clearer to understand, we note the change in their behavior in a tabular form:
+---------------+-------------------------+--------------------------------------------------------------------+----------------------------------------------------------------+
| Actuator Type | Attribute | v1.4.0 Behavior | v2.0.1 Behavior |
+---------------+-------------------------+--------------------------------------------------------------------+----------------------------------------------------------------+
| Implicit | :attr:`velocity_limit` | Ignored, not set into simulation | Set into simulation |
| Implicit | :attr:`effort_limit` | Set into simulation | Set into simulation |
| Explicit | :attr:`velocity_limit` | Used by actuator models (e.g., DC Motor), not set into simulation | Used by actuator models (e.g., DC Motor), set into simulation |
| Explicit | :attr:`effort_limit` | Used by actuator models, not set into simulation | Used by actuator models, set into simulation |
+---------------+-------------------------+--------------------------------------------------------------------+----------------------------------------------------------------+
Setting the limits from the configuration into the simulation directly affects the behavior
of the underlying physics engine solver. This impact is particularly noticeable when velocity
limits are too restrictive, especially in joints with high stiffness, where it becomes easier
to reach these limits. As a result, the change in behavior caused previously trained policies
to not function correctly in IsaacLab v2.0.1.
Consequently, we have reverted back to the prior behavior and added :attr:`velocity_limit_sim` and
:attr:`effort_limit_sim` attributes to make it clear that setting those parameters means
changing solver's configuration. The new behavior is as follows:
+----------------------------+--------------------------------------------------------+-------------------------------------------------------------+
| Attribute | Implicit Actuator | Explicit Actuator |
+============================+========================================================+=============================================================+
| :attr:`velocity_limit` | Ignored, not set into simulation | Used by the model (e.g., DC Motor), not set into simulation |
| :attr:`effort_limit` | Set into simulation (same as :attr:`effort_limit_sim`) | Used by the models, not set into simulation |
| :attr:`velocity_limit_sim` | Set into simulation | Set into simulation |
| :attr:`effort_limit_sim` | Set into simulation (same as :attr:`effort_limit`) | Set into simulation |
+----------------------------+--------------------------------------------------------+-------------------------------------------------------------+
Users are advised to use the ``xxx_sim`` flag if they want to directly modify the solver limits.
Removal of ``disable_contact_processing`` flag in ``SimulationCfg``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We have now removed the ``disable_contact_processing`` flag from the :class:`isaaclab.sim.SimulationCfg`
to not have the user worry about these intricacies of the simulator. The flag is always True by
default unless a contact sensor is created (which will internally set this flag to False).
Previously, the flag ``disable_contact_processing`` led to confusion about its
behavior. As the name suggests, the flag controls the contact reporting from the
underlying physics engine, PhysX. Disabling this flag (note the double negation)
means that PhysX collects the contact information from its solver and allows
reporting them to the user. Enabling this flag means this operation is not performed and
the overhead of it is avoided.
Many of our examples (for instance, the locomotion environments) were setting this
flag to True which meant the contacts should **not** get reported. However, this issue
was not noticed earlier since GPU simulation bypasses this flag, and only CPU simulation
gets affected. Running the same examples on CPU device led to different behaviors
because of this reason.
Existing users, who currently set this flag themselves, should receive a deprecated
warning mentioning the removal of this flag and the switch to the new default behavior.
Switch to older rendering settings to improve render quality
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
With the IsaacLab 2.0.0 release, we switched to new render settings aimed at improving
tiled-rendering performance, but at the cost of reduced rendering quality. This change
particularly affected dome lighting in the scene, which is the default in many of our examples.
As reported by several users, this change negatively impacted render quality, even in
cases where it wasn't necessary (such as when recording videos of the simulation). In
response to this feedback, we have reverted to the previous render settings by default
to restore the quality users expected.
For users looking to trade render quality for speed, we will provide guidelines in the future.
v2.0.1
======
Overview
--------
This release contains a small set of fixes and improvements.
The main change was to maintain combability with the updated library name for RSL RL, which breaks the previous
installation methods for Isaac Lab. This release provides the necessary fixes and updates in Isaac Lab to accommodate
for the name change and maintain compatibility with installation for RSL RL.
**Full Changelog**: https://github.com/isaac-sim/IsaacLab/compare/v2.0.0...v2.0.1
Improvements

v2.0.0
======
Overview
--------
Isaac Lab 2.0 brings some exciting new features, including a new addition to the Imitation Learning workflow with
the **Isaac Lab Mimic** extension.
Isaac Lab Mimic provides the ability to automatically generate additional trajectories based on just a few human
collected demonstrations, allowing for larger training datasets with less human effort. This work is based on the
`MimicGen <https://mimicgen.github.io/>`_ work for Scalable Robot Learning using Human Demonstrations.
Additionally, we introduced a new set of AMP tasks based on
`Adversarial Motion Priors <https://xbpeng.github.io/projects/AMP/index.html>`_, training humanoid robots to walk, run,
and dance.
Along with Isaac Lab 2.0, Isaac Sim 4.5 brings several new and breaking changes, including a full refactor of the
Isaac Sim extensions, an improved URDF importer, an update to the PyTorch dependency to version 2.5.1, and many
fixes for tiled rendering that now supports multiple tiled cameras at different resolutions.
To follow the refactoring in Isaac Sim, we made similar refactoring and restructuring changes to Isaac Lab.
These breaking changes will no longer be compatible with previous Isaac Sim versions.
.. attention::
Please make sure to update to Isaac Sim 4.5 when using the Isaac Lab 2.0 release.
**Full Changelog**: https://github.com/isaac-sim/IsaacLab/compare/v1.4.1...v2.0.0

.. attention::
We have identified a breaking feature for semantic segmentation and instance segmentation when using
``Camera`` and ``TiledCamera`` with instanceable assets. Since the Isaac Sim 4.5 / Isaac Lab 2.0 release, semantic and instance
segmentation outputs only render the first tile correctly and produces blank outputs for the remaining tiles.
We will be introducing a workaround for this fix to remove scene instancing if semantic segmentation or instance
segmentation is required for ``Camera`` and ``TiledCamera`` until we receive a proper fix from Omniverse as part of the next Isaac Sim release.
Migration Guide
---------------
Renaming of Isaac Sim Extensions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Previously, Isaac Sim extensions have been following the convention of ``omni.isaac.*``,
such as ``omni.isaac.core``. In Isaac Sim 4.5, Isaac Sim extensions have been renamed
to use the prefix ``isaacsim``, replacing ``omni.isaac``. In addition, many extensions
have been renamed and split into multiple extensions to prepare for a more modular
framework that can be customized by users through the use of app templates.
Notably, the following commonly used Isaac Sim extensions in Isaac Lab are renamed as follow:
* ``omni.isaac.cloner`` --> :mod:`isaacsim.core.cloner`
* ``omni.isaac.core.prims`` --> :mod:`isaacsim.core.prims`
* ``omni.isaac.core.simulation_context`` --> :mod:`isaacsim.core.api.simulation_context`
* ``omni.isaac.core.utils`` --> :mod:`isaacsim.core.utils`
* ``omni.isaac.core.world`` --> :mod:`isaacsim.core.api.world`
* ``omni.isaac.kit.SimulationApp`` --> :mod:`isaacsim.SimulationApp`
* ``omni.isaac.ui`` --> :mod:`isaacsim.gui.components`
Renaming of the URDF and MJCF Importers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Starting from Isaac Sim 4.5, the URDF and MJCF importers have been renamed to be more consistent
with the other extensions in Isaac Sim. The importers are available on isaac-sim GitHub
as open source projects.
Due to the extension name change, the Python module names have also been changed:
* URDF Importer: :mod:`isaacsim.asset.importer.urdf` (previously :mod:`omni.importer.urdf`)
* MJCF Importer: :mod:`isaacsim.asset.importer.mjcf` (previously :mod:`omni.importer.mjcf`)
From the Isaac Sim UI, both URDF and MJCF importers can now be accessed directly from the File > Import
menu when selecting a corresponding .urdf or .xml file in the file browser.
Changes in URDF Importer
~~~~~~~~~~~~~~~~~~~~~~~~
Isaac Sim 4.5 brings some updates to the URDF Importer, with a fresh UI to allow for better configurations
when importing robots from URDF. As a result, the Isaac Lab URDF Converter has also been updated to
reflect these changes. The :class:`isaaclab.sim.converters.UrdfConverterCfg` includes some new settings,
such as :class:`~isaaclab.sim.converters.JointDriveCfg.PDGainsCfg`
and :class:`~isaaclab.sim.converters.JointDriveCfg.NaturalFrequencyGainsCfg` classes for configuring
the gains of the drives.
One breaking change to note is that the :attr:`~isaaclab.sim.converters.UrdfConverterCfg.JointDriveCfg.gains`
attribute must be of class type :class:`~isaaclab.sim.converters.JointDriveCfg.PDGainsCfg` or
:class:`~isaaclab.sim.converters.JointDriveCfg.NaturalFrequencyGainsCfg`.
The stiffness of the :class:`~isaaclab.sim.converters.JointDriveCfg.PDGainsCfg` must be specified, as such:
.. code-block:: python
joint_drive=sim_utils.UrdfConverterCfg.JointDriveCfg(
gains=sim_utils.UrdfConverterCfg.JointDriveCfg.PDGainsCfg(stiffness=None, damping=None)
)
The :attr:`~isaaclab.sim.converters.JointDriveCfg.NaturalFrequencyGainsCfg.natural_frequency` attribute must
be specified for :class:`~isaaclab.sim.converters.JointDriveCfg.NaturalFrequencyGainsCfg`.
Renaming of Isaac Lab Extensions and Folders
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Corresponding to Isaac Sim 4.5 changes, we have also made some updates to the Isaac Lab directories and extensions.
All extensions that were previously under ``source/extensions`` are now under the ``source/`` directory directly.
The ``source/apps`` and ``source/standalone`` folders have been moved to the root directory and are now called
``apps/`` and ``scripts/``.
Isaac Lab extensions have been renamed to:
* ``omni.isaac.lab`` --> :mod:`isaaclab`
* ``omni.isaac.lab_assets`` --> :mod:`isaaclab_assets`
* ``omni.isaac.lab_tasks`` --> :mod:`isaaclab_tasks`
In addition, we have split up the previous ``source/standalone/workflows`` directory into ``scripts/imitation_learning``
and ``scripts/reinforcement_learning`` directories. The RSL RL, Stable-Baselines, RL_Games, SKRL, and Ray directories
are under ``scripts/reinforcement_learning``, while Robomimic and the new Isaac Lab Mimic directories are under
``scripts/imitation_learning``.
To assist with the renaming of Isaac Lab extensions in your project, we have provided a
`simple script <https://gist.github.com/kellyguo11/3e8f73f739b1c013b1069ad372277a85>`_ that will traverse
through the ``source`` and ``docs`` directories in your local Isaac Lab project and replace any instance of the renamed
directories and imports. **Please use the script at your own risk as it will overwrite source files directly.**
Restructuring of Isaac Lab Extensions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
With the introduction of :mod:`isaaclab_mimic`, designed for supporting data generation workflows for imitation learning,
we have also split out the previous ``wrappers`` folder under ``isaaclab_tasks`` to its own module, named :mod:`isaaclab_rl`.
This new extension will contain reinforcement learning specific wrappers for the various RL libraries supported by Isaac Lab.
The new :mod:`isaaclab_mimic` extension will also replace the previous imitation learning scripts under the ``robomimic`` folder.
We have removed the old scripts for data collection and dataset preparation in favor of the new mimic workflow. For users
who prefer to use the previous scripts, they will be available in previous release branches.
Additionally, we have also restructured the :mod:`isaaclab_assets` extension to be split into ``robots`` and ``sensors``
subdirectories. This allows for clearer separation between the pre-defined configurations provided in the extension.
As an example, the following import:
.. code-block:: python
from omni.isaac.lab_assets.anymal import ANYMAL_C_CFG
should be replaced with:
.. code-block:: python
from isaaclab_assets.robots.anymal import ANYMAL_C_CFG

Most importantly, we reverted one of the `changes from the previous release <https://github.com/isaac-sim/IsaacLab/pull/966>`_
to ensure the training throughput performance remains the same.
**Full Changelog**: https://github.com/isaac-sim/IsaacLab/compare/v1.4.0...v1.4.1
This is the **final release compatible with Isaac Sim 4.2**. The next release will target Isaac Sim 4.5,
which introduces breaking changes that will make Isaac Lab incompatible with earlier versions of Isaac Sim.

Migration Guide
---------------
Setting the simulation device into the simulation context
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Previously, changing the simulation device to CPU required users to set other simulation parameters
(such as disabling GPU physics and GPU pipelines). This made setting up the device appear complex.
We now simplify the checks for device directly inside the simulation context, so users only need to
specify the device through the configuration object.
Before:
.. code:: python
sim_utils.SimulationCfg(device="cpu", use_gpu_pipeline=False, dt=0.01, physx=sim_utils.PhysxCfg(use_gpu=False))
Now:
.. code:: python
sim_utils.SimulationCfg(device="cpu", dt=0.01, physx=sim_utils.PhysxCfg())
Setting the simulation device from CLI
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Previously, users could specify the device through the command line argument ``--device_id``. However,
this made it ambiguous when users wanted to set the device to CPU. Thus, instead of the device ID,
users need to specify the device explicitly through the argument ``--device``.
The valid options for the device name are:
* "cpu": runs simulation on CPU
* "cuda": runs simulation on GPU with device ID at default index
* "cuda:N": runs simulation on GPU with device ID at ``N``. For instance, "cuda:0" will use device at index "0".
Due to the above change, the command line interaction with some of the scripts has changed.
Before:
.. code:: bash
./isaaclab.sh -p source/standalone/workflows/sb3/train.py --task Isaac-Cartpole-v0 --headless --cpu
Now:
.. code:: bash
./isaaclab.sh -p source/standalone/workflows/sb3/train.py --task Isaac-Cartpole-v0 --headless --device cpu
Renaming of teleoperation device CLI in standalone scripts
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Since ``--device`` is now an argument provided by the AppLauncher, it conflicted with the command-line
argument used for specifying the teleoperation-device in some of the standalone scripts. Thus, to fix
this conflict, the teleoperation-device now needs to be specified through ``--teleop_device`` argument.
Before:
.. code:: bash
./isaaclab.sh -p source/standalone/environments/teleoperation/teleop_se3_agent.py --task Isaac-Lift-Cube-Franka-IK-Rel-v0 --num_envs 1 --device keyboard
Now:
.. code:: bash
./isaaclab.sh -p source/standalone/environments/teleoperation/teleop_se3_agent.py --task Isaac-Lift-Cube-Franka-IK-Rel-v0 --num_envs 1 --teleop_device keyboard
Using Python-version of container utility script
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The prior `container.sh <https://github.com/isaac-sim/IsaacLab/blob/v1.1.0/docker/container.sh>`_ became quite
complex as it had many different use cases in one script. For instance, building a docker image for "base" or "ros2",
as well as cluster deployment. As more users wanted to have the flexibility to overlay their own docker settings,
maintaining this bash script became cumbersome. Hence, we migrated its features into a Python script in this release.
Additionally, we split the cluster-related utilities into their own script inside the ``docker/cluster`` directory.
We still maintain backward compatibility for ``container.sh``. Internally, it calls the Python script ``container.py``.
We request users to use the Python script directly.
Before:
.. code:: bash
./docker/container.sh start
Now:
.. code:: bash
./docker/container.py start
Using separate directories for logging videos in RL workflows
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Previously, users could record videos during the RL training by specifying the ``--video`` flag to the
``train.py`` script. The videos would be saved inside the ``videos`` directory in the corresponding log
directory of the run.
Since many users requested to also be able to record videos while inferencing the policy, recording
videos have also been added to the ``play.py`` script. Since changing the prefix of the video file
names is not possible, the videos from the train and play scripts are saved inside the ``videos/train``
and ``videos/play`` directories, respectively.
Drops support for the tiled camera with Isaac Sim 4.1
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Various fixes have been made to the tiled camera rendering pipeline in Isaac Sim 4.2. This made
supporting the tiled camera with Isaac Sim 4.1 difficult. Hence, for the best experience, we advice
switching to Isaac Sim 4.2 with this release of Isaac Lab.
v1.1.0
======
Overview
--------
With the release of Isaac Sim 4.0 and 4.1, support for Isaac Sim 2023.1.1 has been discontinued.
We strongly encourage all users to upgrade to Isaac Sim 4.1 to take advantage of the latest features
and improvements. For detailed information on this upgrade, please refer to the release notes available
`here <https://docs.isaacsim.omniverse.nvidia.com/latest/overview/release_notes.html#>`__.
Besides the above, the Isaac Lab release brings new features and improvements, as detailed below. We thank
all our contributors for their continued support.
**Full Changelog**: https://github.com/isaac-sim/IsaacLab/compare/v1.0.0...v1.1.0
New Features
------------
* Adds distributed multi-GPU learning support for skrl by @Toni-SM

* Fixes action term in the reach environment by @masoudmoghani
* Fixes training UR10 reach with RL_GAMES and SKRL by @sudhirpratapyadav
* Adds event manager call to simple manage-based env by @Mayankm96
Breaking Changes
----------------
* Drops official support for Isaac Sim 2023.1.1
* Removes the use of body view inside the asset classes by @Mayankm96
* Renames ``SimulationCfg.substeps`` to ``SimulationCfg.render_interval`` by @Dhoeller19
Migration Guide
---------------
Renaming of ``SimulationCfg.substeps``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Previously, the users set both ``omni.isaac.lab.sim.SimulationCfg.dt`` and
``omni.isaac.lab.sim.SimulationCfg.substeps``, which marked the physics insulation time-step and sub-steps,
respectively. It was unclear whether sub-steps meant the number of integration steps inside the physics time-step
``dt`` or the number of physics steps inside a rendering step.
Since in the code base, the attribute was used as the latter, it has been renamed to ``render_interval`` for clarity.
Removal of Deprecated Attributes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
As notified in previous releases, we removed the classes and attributes marked as deprecated. These are as follows:
* The ``mdp.add_body_mass`` method in the events. Please use the ``mdp.randomize_rigid_body_mass`` instead.
* The classes ``managers.RandomizationManager`` and ``managers.RandomizationTermCfg``. Please use the
``managers.EventManager`` and ``managers.EventTermCfg`` classes instead.
* The following properties in ``omni.isaac.lab.sensors.FrameTransformerData``:
* ``target_rot_source`` --> ``target_quat_w``
* ``target_rot_w`` --> ``target_quat_source``
* ``source_rot_w`` --> ``source_quat_w``
* The attribute ``body_physx_view`` from the ``omni.isaac.lab.assets.Articulation`` and
``omni.isaac.lab.assets.RigidObject`` classes. These caused confusion when used with the articulation view
since the body names did not follow the same ordering.
v1.0.0
======
Overview
--------
Welcome to the first official release of Isaac Lab!
Building upon the foundation of the `Orbit <https://isaac-orbit.github.io/>`_ framework, we have integrated
the RL environment designing workflow from `OmniIsaacGymEnvs <https://github.com/NVIDIA-Omniverse/OmniIsaacGymEnvs>`_.
This allows users to choose a suitable :ref:`task-design approach <ref_arch>`
for their applications.
While we maintain backward compatibility with Isaac Sim 2023.1.1, we highly recommend using Isaac Lab with
Isaac Sim 4.0.0 version for the latest features and improvements.
**Full Changelog**: https://github.com/isaac-sim/IsaacLab/compare/v0.3.1...v1.0.0
New Features
------------
* Integrated CI/CD pipeline, which is triggered on pull requests and publishes the results publicly
* Extended support for Windows OS platforms
* Added tiled render based Camera
sensor implementation. This provides optimized RGB-D rendering throughputs of up to 10k frames per second.
* Added support for multi-GPU and multi-node training for the RL-Games library
* Integrated APIs for environment designing (direct workflow) without relying on managers
* Added implementation of delayed PD actuator model
* Added various new learning environments:
* Cartpole balancing using images
* Shadow hand cube reorientation
* Boston Dynamics Spot locomotion
* Unitree H1 and G1 locomotion
* ANYmal-C navigation
* Quadcopter target reaching
Improvements
------------
* Reduced start-up time for scripts (inherited from Isaac Sim 4.0 improvements)
* Added lazy buffer implementation for rigid object and articulation data. Instead of updating all the quantities
at every step call, the lazy buffers are updated only when the user queries them
* Added SKRL support to more environments
Breaking Changes
----------------
For users coming from Orbit, this release brings certain breaking changes. Please check the migration guide for more information.
