undefined method `app.escape_html'

[kodekrash]

Using middleman 4.1.1

When running bundle exec middleman build

middleman-sitemap-0.0.13/lib/middleman-sitemap/extension.rb:94:in block in encode: undefined method app.escape_html

Verified that escape_html is available to middleman with simple test template

<%= encode_html( '<p>Hello world!</p>' ) %>

Looks like escape_html is gone in middleman 4.1

Apparently escape_html is just as present in MM 4.1 (padrino-helpers 0.13) as it was in 3.3 (padrino-helpers-0.12).

This issue was fixed by @matsu911 and is in a pull request.

@matsu911 also forked the repo and added this fix to the fork.

I was able to use the forked repo with Middleman v4 and everything is working great. This is what I added to my Gemfile:

gem "middleman-sitemap", :git => "https://github.com/matsu911/middleman-sitemap"

Using that repo gives the error /home/james/.rvm/rubies/ruby-2.3.1/lib/ruby/gems/2.3.0/bundler/gems/middleman-sitemap-b52c2256d418/templates/sitemap.xml.erb:4:in 'block (2 levels) in singleton class': undefined method '+' for nil:NilClass (NoMethodError)
