Perhaps somebody might be interested in an overview of the different Zend Framework versions that are used in each Magento CE release, e.g. if you are developing Magento modules and want to use some kind of Zend Framework methods that are only available after a certain ZF version.
The ZF version info can be derived from file lib/Zend/Version.php.
So here is an overview of the Zend Framework version for each Magento CE release since 1.2.x:
|Zend Framework Version||Magento Versions|
|1.12.16||126.96.36.199 – 188.8.131.52|
|1.12.3||184.108.40.206 – 220.127.116.11|
|1.11.1||18.104.22.168 – 22.214.171.124|
|1.9.6||126.96.36.199 – 188.8.131.52|
|1.7.2||1.2.x – 184.108.40.206|
