Yeh we have a client on an ancient CentOS version running PHP 5.3. I know, PHP 5.3 is basically dead but it’s not in our control to update their stack. This update basically renders this plugin useless. We’ve downgraded but a little more heads-up would have been nice.
As stickster mentioned, it’s really an amateur move to change the PHP requirement in a point release. Maybe we’re old school but this is the kind of a thing that you change in a 2.0 release. I usually don’t write negative reviews but this is the kind of thing that I’d give 1 stars on the repo for.
