Glad to hear its not a security update, that way I do not feel guilty about not updating all my websites using MT because of one patch to fix a max user connections error.

Thank you Takeshi.

I got a question : is it a critical patch ?

If I got Movable Type 5.2.2 and a MySQL DB, do i really need to upgrade asap or can i wait for the next patch ?

You do not need to update your MT, because it is 5.x. This patch is for users who use MT4.38 and previous versions.

Though I recommend you to check your mt-upgrade.cgi whether its permission is executable from external users or not, to avoid trouble.

Marc, this is not a critical patch, but one meant to allow the installation process or the upgrade process to complete on some specific server environments where the ‘maxuserconnections’ setting was limited to a value smaller than the one movable type v5.2.2 needed.

In other words if you’ve been able to install or upgrade to v5.2.2, then you don’t need this release.

Hi Takeshi, could you please explain a bit more about the possible troubles, connected with the executable permissions in the mt-upgrade.cgi. Thank you in advance.

Thanks for the udpate, Takeshi. We really needed to upgrade some of our clients due to the FB integration quirk we’ve been having with an older release in the 4.x series, and this did the trick.
