What's Changed
- Update Vega-Lite from version 4.17.0 to version 5.8.0; see [Vega-Lite Release Notes](https://github.com/vega/vega-lite/releases).
Enhancements
- As described in the release notes for [Vega-Lite 5.0.0](https://github.com/vega/vega-lite/releases/tag/v5.0.0), the primary change in this release of Altair is the introduction of parameters. There are two types of parameters, selection parameters and variable parameters. Variable parameters are new to Altair, and while selections are not new, much of the old terminology has been deprecated. See [Slider Cutoff](https://altair-viz.github.io/gallery/slider_cutoff.html) for an application of variable parameters (#2528).
- Grouped bar charts and jitter are now supported using offset channels, see [Grouped Bar Chart with xOffset](https://altair-viz.github.io/gallery/grouped_bar_chart2.html) and [Strip Plot Jitter](https://altair-viz.github.io/gallery/strip_plot_jitter.html).
- [`vl-convert`](https://github.com/vega/vl-convert) is now used as the default backend for saving Altair charts as svg and png files, which simplifies saving chart as it does not require external dependencies like `altair_saver` does (#2701). Currently, `altair_saver` does not support Altair 5 and it is recommended to switch to [`vl-convert`](https://github.com/vega/vl-convert). See [PNG, SVG, and PDF format](https://altair-viz.github.io/user_guide/saving_charts.html#png-svg-and-pdf-format) for more details.
- Saving charts with HTML inline is now supported without having `altair_saver` installed (2807).
- The default chart width was changed from `400` to `300` (2785).
- Ordered pandas categorical data are now automatically encoded as sorted ordinal data (2522)
- The `Title` and `Impute` aliases were added for `TitleParams` and `ImputeParams`, respectively (2732).
- The documentation page has been revamped, both in terms of appearance and content.
- More informative autocompletion by removing deprecated methods (2814) and for editors that rely on type hints (e.g. VS Code) we added support for completion in method chains (2846) and extended keyword completion to cover additional methods (2920).
- Substantially improved error handling. Both in terms of finding the more relevant error (2842), and in terms of improving the formatting and clarity of the error messages (2824, 2568, 2979, 3009).
- Include experimental support for the DataFrame Interchange Protocol (through `__dataframe__` attribute). This requires `pyarrow>=11.0.0` (2888).
- Support data type inference for columns with special characters (2905).
- Responsive width support using `width="container"` when saving charts to html or displaying them with the default `html` renderer (2867).
Grammar Changes
- Channel options can now be set via a more convenient method-based syntax in addition to the previous attribute-based syntax. For example, instead of `alt.X(..., bin=alt.Bin(...))` it is now recommend to use `alt.X(...).bin(...)`) (2795). See [Method-Based Syntax](https://altair-viz.github.io/user_guide/encodings/index.html#method-based-attribute-setting) for details.
- `selection_single` and `selection_multi` are now deprecated; use `selection_point` instead. Similarly, `type=point` should be used instead of `type=single` and `type=multi`.
- `add_selection` is deprecated; use `add_params` instead.
- The `selection` keyword argument must in many cases be replaced by `param` (e.g., when specifying a filter transform).
- The `empty` keyword argument for a selection parameter should be specified as `True` or `False` instead of `all` or `none`, respectively.
- The `init` keyword argument for a parameter is deprecated; use `value` instead.
Bug Fixes
- Displaying a chart not longer changes the shorthand syntax of the stored spec (2813).
- Fixed `disable_debug_mode` (2851).
- Fixed issue where the webdriver was not working with Firefox's geckodriver (2466).
- Dynamically determine the jsonschema validator to avoid issues with recent jsonschema versions (2812).
Backward-Incompatible Changes
- Colons in column names must now be escaped to remove any ambiguity with encoding types. You now need to write `"column\:name"` instead of `"column:name"` (2824).
- Removed the Vega (v5) wrappers and deprecate rendering in Vega mode (save Chart as Vega format is still allowed) (2829).
- Removed the Vega-Lite 3 and 4 wrappers (2847).
- Removed the deprecated datasets.py (3010).
- In regards to the grammar changes listed above, the old terminology will still work in many basic cases. On the other hand, if that old terminology gets used at a lower level, then it most likely will not work. For example, in the current version of [Scatter Plot with Minimap](https://altair-viz.github.io/gallery/scatter_with_minimap.html), two instances of the key `param` are used in dictionaries to specify axis domains. Those used to be `selection`, but that usage is not compatible with the current Vega-Lite schema.
- Removed the ``altair.sphinxext`` module (2792). The ``altair-plot`` Sphinx directive is now part of the [sphinxext-altair](https://github.com/altair-viz/sphinxext-altair) package.
Maintenance
- Vega-Altair now uses `hatch` for package management.
- Vega-Altair now uses `ruff` for linting.
