E’ possibile fare l’aggiornamento alla versione 22.214.171.124 con Magento Connect Manager?
It is possible that you will see no extensions in MagentoConnect Manager. This means that you have just uploaded the files without using PEAR downloader. In that case enter magento-core/Mage_All_Latest in the extension key field and click Install button. This will install all latest MagentoConnect core packages on top of existing files and will allow future upgrades through MagentoConnect.
