This plugin adds <a href="https://www.google.com/recaptcha/" rel="nofollow ugc">Google’s reCAPTCHA</a> to the BuddyPress registration page and WordPress login page to prevent bots from registering and keep your site free from spam registrations.
reCAPTCHA is “tough on bots, easy on humans”: while it is increbianle effective on preventing bots from registering, most of the time all the user needs to do to verify themselves is simply check a box.
After installing this plugin, you will need to <a href="https://www.google.com/recaptcha/admin" rel="nofollow ugc">register your site with Google</a> (requires a Google account) and enter the site key and secret key on the Settings > BuddyPress > Options admin menu. If you would prefer not to use Google’s service, there is an alternative security check method also available; see below;
Prior to version 2.0, a less effective security check method was used where the user needed to answer simple math sum before registering. This method is still available, and can be turned on on the Settings > BuddyPress > Options menu.

🛠️ Shortcode Manager (Add/Edit/Delete Shortcodes from WP Admin) 
A powerful Shortcode Manager has been introduced in the WordPress admin area. 
With this new feature, you can: 
Add custom shortcodes for any converter type 
Edit existing shortcodes to fine-tune their settings 
Delete unused shortcodes easily
🚀 New features 
Each generated shortcode is now fully customizable — you can select exactly which units to include in the converter. This means you can now create highly specific converters (e.g., only inches ↔ centimeters, or only kilograms ↔ pounds) right from the Shortcode Manager page. 
This gives you the flexibility to: 
Create multiple custom converters tailored to different content types 
Display only relevant units for your audience 
Avoid overwhelming users with unnecessary unit choices 
🧩 In short: You can now generate unlimited custom unit converters directly from your admin panel — no coding needed.
<h3>Example Shortcodes</h3>
Use the <code>type</code> attribute to specify the converter or calculator. You can also use the <code>style</code> attribute to customize layout (e.g., <code>table</code>, <code>list</code>).
<ul>
<li><code>[codeart_units_converter_converters type='weight' style='table']</code></li>
<li><code>[codeart_units_converter_converters type='speed' style='table']</code></li>
<li><code>[codeart_units_converter_converters type='area' style='table']</code></li>
<li><code>[codeart_units_converter_converters type='volume' style='table']</code></li>
<li><code>[codeart_units_converter_converters type='length' style='table']</code></li>
<li>and more…</li>
</ul>
