The 6.x reference at a glance

This is the reference of Exponential 6, for the kernel of Exponential 6.0.15. It began as a copy of the 4.x reference, whose pages still hold for what 6.x kept; what 6.x added has pages of its own, marked "Added to the reference for Exponential 6.0.15", and each says the release it arrived in. Pages of things 6.x changed have a section "Changed in Exponential 6.0.15"; what the kernel of 6.0.15 no longer has is marked "Not part of Exponential 6.0.15".

Extensions	The extensions that ship with Exponential 6 and what each one registers.	73	55
Libraries	The libraries in lib/.	27	3
Modules	The modules, their views, policies and fetch functions.	716	14
Objects	The persistent objects and their tables.	147	20
Scripts	The scripts of bin/php and the console commands.	242	153
Template control structures	if, switch, foreach and the other control structures of the template language.	29	-
Template fetch functions	The fetch functions templates call, by module.	below Modules	49
Template functions	The template functions.	230	-
Template operators	The template operators, by category.	381	87
Template override conditions	The override keys each view sets.	51	5

"New in 6.x" counts the items that arrived in the 6.0.x releases (6.0.15 in development included); the views and fetch functions are counted in their own sections, their pages are below the modules.
