v5.7.0

Notable Additions:

• The text mark now supports multi-line text. Multiples lines are specified by setting the text channel to an array of strings (one per line).
• The title directive now supports subtitle text and corresponding configuration properties.
• Title text in axes, legends, and titles can now span multiple lines (as an array of strings).
• New transforms for dot plot layout and quantile estimation.
• New expression functions for statistical distributions.
• Legend symbolLimit property controls the number of entries shown in a symbol legend. The default configuration imposes a 30 entry limit.
• Configuration support for default cartographic projection properties.

Deprecations:

• The title directive's top-level name, interactive, and style properties, along with the flat encode block for title text, are now deprecated and will be removed in Vega 6.0. Instead, please use nested encode blocks using the keys title or subtitle. This new form is more expressive and consistent with custom encode blocks for axes and legends.
