Securimage 3.6 has been released which includes the following new features:
- HTML5 audio playback for compatibility mobile devices and removes the need for Flash
- Audio can be streamed in MP3 format (requires LAME; see the HTML5 audio docs for more info)
- Easier integration with MVC frameworks when using Securimage::getCaptchaHtml() method
If you use an older version, consider upgrading to 3.6, and new users should download 3.6. There are no issues upgrading old versions to the latest. Simply overwrite your existing files (make sure to preserve any custom changes to securimage_show.php or other files).
The WordPress plugin was also updated to use the latest version of Securimage and now supports HTML5 audio as well.
Somewhat unrelated, all comments to posts and pages have been deleted since many were old, no longer apply, and it was getting a bit difficult to sift through all the comments to find relevant information.
