+``cuda.core`` 0.1.0 Release Notes
+=================================
 
 Released on Nov 8, 2024
 
-## Hightlights
+Highlights
+----------
+
 - Initial beta release
 - Supports all platforms that CUDA is supported
 - Supports all CUDA 11.x/12.x drivers
 - Supports all CUDA 11.x/12.x Toolkits
 - Pythonic CUDA runtime and other core functionalities
 
-## Limitations
+Limitations
+-----------
 
 - All APIs are currently *experimental* and subject to change without deprecation notice.
-  Please kindly share your feedbacks with us so that we can make `cuda.core` better!

+``cuda.core`` 0.1.1 Release Notes
+=================================
+
+Released on Dec 20, 2024
+
+Highlights
+----------
+
+- Add :obj:`~utils.StridedMemoryView` and :func:`~utils.args_viewable_as_strided_memory` that provide a concrete
+  implementation of DLPack & CUDA Array Interface supports.
+- Add :obj:`~Linker` that can link one or multiple :obj:`~_module.ObjectCode` instances generated by :obj:`~Program`. Under
+  the hood, it uses either the nvJitLink or driver (``cuLink*``) APIs depending on the CUDA version
+  detected in the current environment.
+- Support ``pip install cuda-core``. Please see the Installation Guide for further details.
+
+New features
+------------
+
+- Add a :obj:`cuda.core.experiemental.system` module for querying system- or process-wide information.
+- Add :obj:`~LaunchConfig.cluster` to support thread block clusters on Hopper GPUs.
+
+Enhancements
+------------
+
+- The internal handle held by :obj:`~_module.ObjectCode` is now lazily initialized upon first touch.
+- Support TCC devices with a default synchronous memory resource to avoid the use of memory pools.
+- Ensure ``"ltoir"`` is a valid code type to :obj:`~_module.ObjectCode`.
+- Document the ``__cuda_stream__`` protocol.
+- Improve test coverage & documentation cross-references.
+- Enforce code formatting.
+
+Bug fixes
+---------
+
+- Eliminate potential class destruction issues.
+- Fix circular import during handling a foreign CUDA stream.
+
+Limitations
+-----------
+
+- All APIs are currently *experimental* and subject to change without deprecation notice.
+  Please kindly share your feedback with us so that we can make ``cuda.core`` better!
+- Using ``cuda.core`` with NVRTC or nvJitLink installed from PyPI via `pip install` is currently
+  not supported. This will be fixed in a future release.
+- Some :class:`~LinkerOptions` are only available when using a modern version of CUDA. When using CUDA <12,
+  the backend is the cuLink API which supports only a subset of the options that nvjitlink does.
+  Further, some options aren't available on CUDA versions <12.6.
+- To use ``cuda.core`` with Python 3.13, it currently requires building ``cuda-python`` from source
+  prior to `pip install`. This extra step will be fixed soon.

+``cuda.core`` 0.2.0 Release Notes
+=================================
+
+Released on <TODO>, 2024
+
+Highlights
+----------
+
+- Add :class:`~ProgramOptions` to facilitate the passing of runtime compile options to :obj:`~Program`.
+
+Limitations
+-----------
+
+- <TODO>
+
+Breaking Changes
+----------------
+
+- The :meth:`~Program.compile` method no longer accepts the `options` argument. Instead, you can optionally pass an instance of :class:`~ProgramOptions` to the constructor of :obj:`~Program`.
