This release brings one of the most requested features - interactive twin-axis support! Another feature added in this release is the ability to easily set custom options on plot components with `backend_opts`, making it much easier to customize your plots. Datashaders `where` and `summary` aggregators are now supported, and `rasterize` now has a `selector` option, making it easy to get extra information about your rasterized data. Lastly, Bokeh figures with the same labels will synchronize muteness or visibility across different figures.

In addition, this release includes several enhancements and bug fixes.

Many thanks to the new contributors alfredocarella and RaulPL, as well as the returning contributors ahuang11, droumis, jbednar, jlstevens, maximlt, philippjfr, TheoMathurin and Hoxbro.

**June 8, 2023**

This release includes a breaking change as notebooks will no longer be inlining as default. This change will reduce the size of the notebook files and, more importantly, address an upstream issue in Jupyter where running `hv.extension` would give an error when used in a notebook.

Critical bug fixes and compatibility:

- Correctly set `inline=False` when running `hv.extension` in a Jupyter Notebook ([5748](https://github.com/holoviz/holoviews/pull/5748))
- Adding more Param 2 support ([5717](https://github.com/holoviz/holoviews/pull/5717))

Enhancements:

- Speed up import time of Holoviews ([5719](https://github.com/holoviz/holoviews/pull/5719))

Maintenance:

- Fix failing tests ([5742](https://github.com/holoviz/holoviews/pull/5742))
- Misc. mainteance ([5717](https://github.com/holoviz/holoviews/pull/5717))
