Signet PDF 2.x
This is the archived documentation for the 2.x line, frozen at 2.0.1. It is the prose that shipped with that release, published as it stood.
For the line that is current now, use the version control in the navigation, or go to the current documentation.
2.x is the release that left the framework behind: the entry point became a fluent builder, configuration became value objects, and the container went away. What 3.x changed on top of that is in Upgrading.
