Better WordPress reCAPTCHA (with no CAPTCHA reCAPTCHA)

(2016-01-13) =

• New Features
  • Allow adding custom CSS rules to control the look and feel of recaptcha instances. To enable this feature, navigate to BWP reCAPT >> Theme Options, choose to enable Custom CSS, and then customize the default CSS rules however you like.
• Enhancements
  • Allow setting a request method to work around the "invalid-json" error. With this change fsockopen is preferred to cURL, and will be the first to be used to communicate with reCAPTCHA's server.
• Other Changes
  • Marked as compatible with WordPress 4.4+.
  • Update language template file and translation files. If you're a translator, please help translating this plugin (your name and website will be listed on this plugin's page!) For more info, see: http://betterwp.net/wordpress-tips/create-pot-file-using-poedit/
• Bugs fixed
  • Fix a bug that results in captcha not showing on certain login pages. Affected login pages include:
    • Login page that uses secured HTTP (HTTPS)
    • Login page of a child blog in a sub-directory multisite installation.

• New Features
  • Add an option to treat invalid captcha as spam or a validation error. For more info, see: http://contactform7.com/spam-filtering-with-akismet/.
    • If you treat invalid captcha as validation error, it is now possible to customize the error message shown under the captcha as well.
    • Previously, for the recaptcha shortcode tag to work you must add it to your form like this: [recaptcha a-field-name]. The field name is now optional, but is still needed if you want to show the error message.
• Other Changes
  • Update language template file. If you're a translator, please help translating this plugin! For more info, see: http://betterwp.net/wordpress-tips/create-pot-file-using-poedit/
  • Display recaptcha error code when an unknown error occurs.
  • Show the option to toggle recaptcha version in PHP 5.3.2+ only. This means in PHP < 5.3.2 there's no option to select recaptcha version, recaptcha version 1 will always be used. This should affect the theme options page as well.
  • Add back support for PHP 5.2.
• Bugs fixed
  • Should always set a correct width for login/registration form so recaptcha fits well inside.
  • Fix recaptcha v1's display in themes that define table-layout: fixed
  • Auto-detect request method for recaptcha v2 to support server with allow_url_fopen disabled.

• New Features
  • Add support for reCAPTCHA version 2
  • Add support for multiple reCAPTCHA instances per page (reCAPTCHA version 2 only)
  • Add an HTTPS setting for reCAPTCHA version 1
• Enhancements
  • Add support for Contact Form version 4.x
  • Add support for custom login/register paths
  • Add reCAPTCHA before the submit field in comment form for WordPress 4.2 or higher
  • Use a lower priority when filter the comment_form_defaults filter hook so reCAPTCHA can still be added to themes that filter it as well
• Other Changes
  • Change minimum PHP version required to 5.3.2
  • Show the captcha to all users (including admins) by default
  • Contact Form 7:
    • The shortcode [bwp-recaptcha] has been deprecated, use [recaptcha recaptcha-xxx] instead.
    • bwp-recaptcha will continue to work for Contact Form 7 prior to version 4.1 (last supported is 4.0.3). bwprecaptcha and bwp_recaptcha will still work with version 4.1+, so you won't have to manually update any form if you're using them.
  • Add a Croatian translation
  • Layerthemes.com has become an official sponsor for BWP Plugins!
• Bugs fixed
  • Fix Akismet integration not working properly
  • Don't output comment form related fields in other forms, which leads to extraneous markups in Contact Form 7 forms
  • Create session only when needed and on demand
  • Fix an issue where saving sub blog's API keys overwrites network's API keys in a multisite installation
• API
  • BWP_RECAPTCHA::load_captcha_library() has been removed, the PHP reCAPTCHA library is now autoloaded whenever needed (for reCAPTCHA version 1).

=

• Fixed an issue where captcha is not displayed but still checked when added to a Contact Form 7 form.

• You can now choose to add captcha below comment text area without using a theme function. More info here
• Added recaptcha shortcode tag back to Contact Form 7. Users can now choose between recaptcha and bwp-recaptcha
• Added support for other plugins that include a slightly different version of reCAPTCHA library to avoid conflicts
• Added Italian reCAPTCHA language (it)
• Removed selective CSS, JS setting in Theme Options
• Removed "Put comment in spam queue" option for Akismet integration. If you still want to use this option add this to your wp-config.php: define('BWP_CAPT_AKISMET_COMMENT_STATUS', 'spam');
• Improved user registration and site registration form on a multi-site installation
• Fixed an issue where a hidden iframe is adding margin to bottom of page in Google Chrome and Safari. This is merely a workaround solution so hopefully Google will fix this issue in reCAPTCHA
• Fixed an issue where captcha is only checked after username and password is correct on login form
• Fixed an issue where a bot can bypass recaptcha on user registration form
• Fixed an issue where some PHP warnings are shown. Note that this fix might cause Akismet integration to fail, so users are advised to test this update first if Akismet integration is enabled
