I have reached a point where I have decided that a lot of core RHP code that has previously been ring fenced (because it is absolutely reliable) needs to be replaced. I am hitting a few limitations imposed by this inflexible early code that is preventing further innovation.
The current plan is to re-write some of the first code ever written for this site (from Jan/Feb 2001!!!). This is quite high risk (understatement), so all the new code will be tested on a 2nd site, and then rolled back into RHP once I am comfortable the new code is 100% stable. This is a mammoth job, so no time frames, but it is essential for future growth of the site.
I still have a massive to-do list for RHP already, and I will try to finally get some of the unreleased things out of the door sooner rather than later. (Conditional moves, I am thinking of you.) But if I go a little quiet over the next few months with regard to new features, this is the reason.
