Drupal alerts an available update (1.23), although a newer version (1.24) is already installed. Additionally you give no information about the changes, which are not as minor as you write!
It is not very convenient to compare the files manually and analyse what has changed to prevent breaking the installed version, so please document more details about the changes! You fixed a major bug corresponding to jQueryUI and some css bugs which prevented menu animations. But did you fix the jQuery version bug?
Hi,
Please always use the newest version (7.x-1.24) because it has bug fixed
About the warning, you do not have to anything. We have fixed update server
It does not affect any megamenu function
