Not the longest run between major overhauls, but a close second at just over three years (a long time in internet years). The big change this time is the move from Bluehost to Hostpapa for the hosting of clements.ca (and jdanielclements.com and coin zoo.net (along with a small pile of domain names)).
I always wanted clements.ca to be on a Canadian server in Canada (with a host who charges the same or less, but in Canadian dollars), but the prospect of moving the whole shebang was too intimidating. But the time was right, and here we are. Besides the hosting move, I have upgraded to the YOOtheme Pro template system, which is quite amazing to work with (and I can afford it with the money I am saving on hosting costs).
Finally, the site is now running on PHP 7.2.x which makes it all faster and more secure (and ready for the release of Joomla 4).
As usual, this post is strictly for my own record keeping and personal edification, so if you are reading this you are probably me. (Hi!)
