By incrementing version number inside block definition you will indicate that this particular block or page need to be updated. Any CMS Block or CMS Page that was changed from magento admin panel will not be updated unless force update mode is defined in update tracking table.

Currently there's no way to manage force update mode from admin panel. This functionality is planned for future extension releases.

You can find cms.xml sample inside extension etc foldet.

Magento Version Helper functions

Goodahead Core extension provides several helper functions to work with Magento version/edition information. Following functions are available from goodahead_core helper:

• getMagentoEdition — returns current magento edition (Community / Enterprise / Professional). Compatible with all magento versions starting from 1.4.1 (corresponding getEdition function in Mage class appeared only starting from 1.7+ Community Edition and 1.12+ Enterprise Edition).
• getMagentoCoreVersion — return corresponding Magento Core version (Community Magento version number that correspond to current Magento version number) for Enterpise and Professional Magento editions. Not 100% accurate (yet) for very old versions and for build numbers.

This functions available in static context as well.

Setup Model with Compatibility functions for older Magento versions

Magento 1.4.1 introduce new library class Varien_Db_Ddl_Table and new method createTable for Varien_Db_Adapter_Pdo_Mysql which allows creating nice install / upgrade scripts using DDL abstraction layer.

Those methods were extended in 1.6 Magento version to provide some additional functionality (like generating Index names, Constraint names, etc.).

Goodahead Core extension provide Goodahead_Core_Model_Resource_Setup model which can be used as your setup model to support DDL install / upgrade scripts like this install-1.0.0.php script.

Please note that some parts require additional verification (like shown in mysql4-install-1.0.0.php)

Extra events to Mage_Core_Model_Email_Template

As we know, this part of Magento is a pain to customize, and hundreds of extensions overwrites this class methods Mage_Core_Model_Email_Template::send(), Mage_Core_Model_Email_Template::sendTransactional(), and Mage_Core_Model_Email_Template::loadDefault(). What to do if you need to use or to build a few extensions with logic in that methods, but you have no events appropriate triggered? -- NOTHING :-(

So, here we have a simple solution, that should help you to avoid problems. Now, if you need to add observer to Magento's kind of mailer, than you can use this events:

• goodahead_core_email_template_loadDefault_before AND goodahead_core_email_template_loadDefault_after;
• goodahead_core_email_template_send_before AND goodahead_core_email_template_send_after;
• goodahead_core_email_template_sendTransactional_before AND goodahead_core_email_template_sendTransactional_after;

IF you still REALLY need to overwrite Mage_Core_Model_Email_Template -- you have to overwrite Goodahead_Core_Model_Email_Template instead, and VERY IMPORTANT(!!!) is to make sure, that event triggers are not removed.
