Previously (here and here) I discussed some changes I was planning to make to Evaluators and EvaluatorGroups. Those two blog posts are a pretty accurate representation of what actually ended up shipping in 2008 r3, so here I will skip the implementation details and instead focus on what the changes mean to you as a user of the libraries.
If you're a casual user of AGI Components and Dynamic Geometry Library, all you really need to know is this: creating evaluators in 2008 r3 is often several times faster than it was in 2008 r2! Ted Driver over at the nog found that his application that computes navigation accuracy over a grid was over 4 times faster when running against r3.
If you're an AGI Components power user (hey, you're reading this blog, you qualify) there are a few things you should know about the new system. Read on.
