3.1.0

• Update our CI matrix to include recent versions of Prawn and Ruby! Thanks @petergoldstein! (#55)
• Resolve a few code smells that were flagged by Rubocop.
• Material Design Icons are now supported! Currently version 7.0.96 is included. Thanks @maneex! (#59)
• Memoize calls to Prawn::Icon::FontData#path to improve performance.

Material Design Icons

All Material Design Icons use the font prefix of mdi. That means that you're able to reference an icon as follows:

require 'prawn/icon'

Prawn::Document.generate('icons.pdf') do |pdf|
  pdf.icon 'mdi-beer', size: 60
end

3.0.0

• breaking change - Fix incorrect layout and line-wrapping logic for inline-formatted icons. Please see Inline Format Changes for more details.
• Add a #formatted_icon_box method to retain the previous inline icon behaviour.
• Allow #formatted_icon_box to accept absolute positioning parameters (x, y, and at). Thanks @navinspm!
• Update fontawesome from version 5.11.2 to 5.15.1.
• See FontAwesome's upgrade guide for more details.
• Introduce a configuration mechanism so that the font directory can be customized as follows:

Prawn::Icon.configure do |config|
  config.font_directory = '/path/to/fonts'
end

• Deprecate the global variables of Prawn::Icon::Base::FONTDIR and Prawn::Icon::Compatibility::SHIMS. Use Prawn::Icon.configuration.font_directory and Prawn::Icon::Compatibility.shims instead.
• Use Gem::Specification#full_gem_path to get the root path of the gem directory to resolve #45.

Inline Format Changes

As noted in #49, Prawn::Icon did not correctly respect page boundaries for inline-formatted icons.

The fix for the issue requires Prawn::Icon to use the inline layout and formatting logic implemented in Prawn.

This change has ramifications to the #icon and #inline_icon method return values, but most applications should not require changes.

Changes are listed below:

• #icon - returns nil with the inline_format: true parameter.
• #inline_icon - returns nil (instead of a Prawn::Text::Formatted::Box instance).

You can call #formatted_icon_box to retain the previous inline icon functionality.

2.1.0

• Introduce backwards compatibility with FontAwesome 4 icon keys by dynamically
  rewriting all instances of fa-* to their appropriate FontAwesome 5 equivalent
  key. This is achieved by implementing a shim generated from the FontAwesome metadata.

  encountered. The compatibility shim will be removed in the next major version
  of Prawn::Icon (3.0.0).
• See the discussion here for more details.
