v0.6.0 - Component lifecycles

on GitHub

Breaking changes:

• Dropped the old Render, Eval, Peek synonyms in favour of the less opaque s -> ComponentHTML f / Natural f (ComponentDSL s f g) types
• The component construction functions use a record now
• parentComponent' is unnecessary, instead the expected record for a parent component has a peek :: Maybe ... field now
• InstalledState and installedState are now called ParentState and parentState
• initializer and finalizer properties have gone, but there are now "lifecycle component" constructors
• The ref property enables capturing a reference to a HTML element
• runUI now requires an element rather than providing one that can be attached later
• Halogen.Util has been reworked to make it more useful with the new runUI

Other changes

• The guide has been moved to its own file an updated for the new changes, including a section on how component lifecycles work
• A package.json is now included in each of the example projects so the virtual-dom dependency is present for each and so that they can be built individually

Much of the credit for this release goes to @natefaubion who did all the work for component lifecycles and has provided insightful commentary throughout.
