All releases of Captcha PHP
Release Notes: Better error detection and visible messages were implemented to notify of setup problems early on. Various bugs were fixed.
Release Notes: Various fixes have been contributed that prevent E_NOTICE errors, provide text translations, and streamline BASE_URL handling. A new TrueType font was added. The AJAX form callback was fixed to prevent the first incorrect status change while entering a CAPTCHA.
Release Notes: This version is almost completely rewritten, but retains the simple API. A new default drawing mode was added. It allows fuzzy solutions and gives feedback via "AJAX". The textual riddle was changed into a math question. It now manages temporary files to track CAPTCHA solving extensively, but retains support for optional time-tagged pass cookies. Logging and URL-triggered activation was added.
Release Notes: Images are now stored in temporary files and data:-URLs are further used only for compliant browsers and when the class has been explicitly configured to do so.
Release Notes: The double-redirection workaround was added for the outdated Microsoft Internet Explorer.
