- Option-setting methods such as ``.opts``, ``.options`` and
``hv.opts`` now allow specifying the backend instead of defaulting
to the current backend

during colormapping
([2483](https://github.com/ioam/holoviews/pull/2483))
- Expanded the [Large Data](http://holoviews.org/user_guide/Large_Data.html)
user guide to show examples of all Element and Container types
supported for datashading and give performance guidelines.

Fixes:

- ``Layout`` and ``Overlay`` objects no longer create lower-case nodes
on attribute access
([2331](https://github.com/ioam/holoviews/pull/2331))

- Fixed timezone issues when using linked streams on datetime axes
([2459](https://github.com/ioam/holoviews/issues/2459))


Changes affecting backwards compatibility:

- Image elements now expect and validate regular sampling
([1869](https://github.com/ioam/holoviews/issues/1869)); for
genuinely irregularly sampled data QuadMesh should be used.
- Tabular elements will no longer default to use ``ArrayInterface``,
instead preferring pandas and dictionary data formats
([1236](https://github.com/ioam/holoviews/issues/1236))
- ``Cycle``/``Palette`` values are no longer zipped together; instead
they now cycle independently
([2333](https://github.com/ioam/holoviews/pull/2333))
- The default color ``Cycle`` was expanded to provide more unique colors
([2483](https://github.com/ioam/holoviews/pull/2483))
- Categorical colormapping was made consistent across backends,
changing the behavior of categorical Matplotlib colormaps
([2483](https://github.com/ioam/holoviews/pull/2483))
- Disabled auto-indexable property of the Dataset baseclass, i.e. if a
single column is supplied no integer index column is added
automatically ([2522](https://github.com/ioam/holoviews/pull/2522))
