RC1

BUG: white page report after check. was occurring because of not initialized parameter in system plugin.
BUG: In administrator back-end, clicking in menu Components - SecurityImages instead of a submenu directly
was showing a white page, this was because of a non default task in the controller class
BUG: Some people report an error while using a language different than English. Since SecurityImages is not
fully localized, fallback to English (en-GB.com_securityimages.ini) if there is no file available.
BUG: fixed non existing static (about, manual) files and fallback to English instead of crashing
NEW: add missing translations for file operations.
NEW: sort languages files and remove duplicated entries
BUG: Found thanks to regression testing
Fatal error: Call to undefined function sendMailLogsToAdmin() in
\\administrator\\components\\com_securityimages\\class\\logUtils.php on line 82

BETA3

BUG: In Edit General Settings - General, the very first option does not have any label. 
BUG: The contact page (in the case of false entry) was showing errors
NEW: More check in Check System page at administrator
NEW: you can now give the size of the captcha for the core plugin. This feature was present in SecurityImages 4.0.X but was lost in translation to SecurityImages 5.0.X
BUG: the reload button was not working properly, in fact only once, this is due to the cache of Joomla! 1.5, solved by adding a timestamp to images URL.

BETA2

From a design point of view, SecurityImages do not come anymore with patches in his code, every 3rd party developer will have to develop and learn how to use SecurityImages 5.0. But coupling is greatly reduce because it use Joomla! events triggering system. 
Joomla! patches are different, I have to maintain them because the core is not meant to be extended in every forms.

ISSUE: Check for latest version causes a 500 internal server error. Wont be solved, that is simply the version manager of soeren (Virtuemart) which is not running with Joomla! 1.5 and not installed on www.waltercedric.com
I will have to wait for Soeren new version or translate his component on myself
ISSUE: reload button is not working, also not always ;-), I am investigating this issue!

NEW: Core don\\\\\\\'t use the database anymore to store captcha but session.
NEW: simplified API for checking captcha
NEW: add reload button in Check Your System menu
BUG: solving logging inclusion (logUtils.php). It was incorrect as soon as you use SecurityImages embedded in another component or module.
NEW: development of Joomla! 1.5 patches and tests with Beta2, see next post
