1.2.1 (2012-04-14)¶ ↑

• Declaring encoding in html5/scrub.rb. Without this, use of the ruby -KU option would cause havoc. (#32)

1.2.0 (2011-08-08)¶ ↑

Enhancements:

• Loofah::Helpers.sanitize_css is a replacement for Rails's built-in sanitize_css helper.

• Improving ActionView integration.

0.4.7 (2010-03-09)¶ ↑

Enhancements:

• New methods Loofah::TextBehavior#to_text and Loofah::TextBehavior#to_text do the right thing with whitespace. Note that these methods are significantly slower than text. GH #12

• Loofah::Elements::BLOCK_LEVEL contains a canonical list of HTML4 block-level4 elements.

• Loofah::TextBehavior#text and Loofah::TextBehavior#text will return unescaped HTML entities by passing :encode_special_chars => false.

0.4.4, 0.4.5, 0.4.6 (2010-02-01)¶ ↑

Enhancements:

• Loofah::TextBehavior#text and Loofah::TextBehavior#text now escape HTML entities.

0.4.3 (2010-01-29)¶ ↑

Enhancements:

• All built-in scrubbers are accepted by ActiveRecord::Base.xss_foliate

• Loofah::XssFoliate.xss_foliate_all_models replaces use of the constant LOOFAH_XSS_FOLIATE_ALL_MODELS

• Implemented Node#scrub! for scrubbing subtrees.

• Implemented NodeSet#scrub! for scrubbing a set of subtrees.
