*Vasiliy Ermolovich*
+* Extract support for email address obfuscation via `:encode`, `:replace_at`, and `replace_dot` options
+ from the `mail_to` helper into the `actionview-encoded_mail_to` gem.
+
+ *Nick Reed + DHH*
+
* Clear url helper methods when routes are reloaded. *Andrew White*
* Fix a bug in `ActionDispatch::Request#raw_post` that caused `env['rack.input']`

+ # +mail_to+ has several methods for customizing the email itself by
+ # passing special keys to +html_options+.
#
# ==== Options
- # * <tt>:encode</tt> - This key will accept the strings "javascript" or "hex".
- # Passing "javascript" will dynamically create and encode the mailto link then
- # eval it into the DOM of the page. This method will not show the link on
- # the page if the user has JavaScript disabled. Passing "hex" will hex
- # encode the +email_address+ before outputting the mailto link.
- # * <tt>:replace_at</tt> - When the link +name+ isn't provided, the
- # +email_address+ is used for the link label. You can use this option to
- # obfuscate the +email_address+ by substituting the @ sign with the string
- # given as the value.
- # * <tt>:replace_dot</tt> - When the link +name+ isn't provided, the
- # +email_address+ is used for the link label. You can use this option to
- # obfuscate the +email_address+ by substituting the . in the email with the
- # string given as the value.
# * <tt>:subject</tt> - Preset the subject line of the email.
# * <tt>:body</tt> - Preset the body of the email.
# * <tt>:cc</tt> - Carbon Copy additional recipients on the email.
# * <tt>:bcc</tt> - Blind Carbon Copy additional recipients on the email.
#
+ # ==== Obfuscation
+ # Prior to Rails 4.0, +mail_to+ provided options for encoding the address
+ # in order to hinder email harvesters. To take advantage of these options,
+ # install the +actionview-encoded_mail_to+ gem.
+ #
# ==== Examples
# mail_to "me@domain.com"
# # => <a href="mailto:me@domain.com">me@domain.com</a>
#
- # mail_to "me@domain.com", "My email", encode: "javascript"
- # # => <script>eval(decodeURIComponent('%64%6f%63...%27%29%3b'))</script>
- #
- # mail_to "me@domain.com", "My email", encode: "hex"
