+Version 0.15.2 (2023-08-17)
+---------------------------
+
+This release adds antialiased line support for inspection reductions such as ``max_n`` and ``where``, including within categorical ``by`` reductions. It also improves support for ``summary`` reductions and adds CUDA implementations of ``std`` and ``var`` reductions.
+
+Thanks to regular contributors `@Hoxbro <https://github.com/Hoxbro>`_, `@ianthomas23 <https://github.com/ianthomas23>`_, `@maximlt <https://github.com/maximlt>`_ and `@thuydotm <https://github.com/thuydotm>`_.
+
+Enhancements:
+
+* Antialiasing line support for inspection reductions:
+
+  - Pre-compile antialias stage 2 combination (`#1258 <https://github.com/holoviz/datashader/pull/1258>`_)
+  - Antialiased min and max row index reductions (`#1259 <https://github.com/holoviz/datashader/pull/1259>`_)
+  - CPU ``shift_and_insert`` function (`#1260 <https://github.com/holoviz/datashader/pull/1260>`_)
+  - Refactor of CUDA ``*_n`` reductions (`#1261 <https://github.com/holoviz/datashader/pull/1261>`_)
+  - Support antialiased lines in ``*_n`` reductions (`#1262 <https://github.com/holoviz/datashader/pull/1262>`_)
+  - Replace accumulate with copy on first call to antialiased stage 2 combine (`#1264 <https://github.com/holoviz/datashader/pull/1264>`_)
+  - Separate where ``combine_cpu`` functions by ndim (`#1265 <https://github.com/holoviz/datashader/pull/1265>`_)
+  - Antialiased line support for ``where`` reductions (`#1269 <https://github.com/holoviz/datashader/pull/1269>`_)
+
+* Improved support for ``summary`` reductions:
+
+  - Support ``by`` reduction within ``summary`` reduction (`#1254 <https://github.com/holoviz/datashader/pull/1254>`_)
+  - Support ``summary`` containing ``by`` reduction with other reductions (`#1257 <https://github.com/holoviz/datashader/pull/1257>`_)
+  - Support ``summary`` containing multiple ``where`` with the same selector (`#1271 <https://github.com/holoviz/datashader/pull/1271>`_)
+
+* CUDA support for ``std`` and ``var`` reductions (`#1267 <https://github.com/holoviz/datashader/pull/1267>`_)
