Breaking changes:

The snapToPanels setting now defaults to false. If you want your panels to snap to the screen set Panels.Settings.snapToPanels = true before calling start.

Features:

added setting for showMainMenuOption
added ability to change advanceControlSize on sequences and panels (Panels.ControlSize.SMALL, .MEDIUM, or .LARGE)
added mainMenuDrawingCallback
added setupFunction to the list of custom functions
added ability to set margins, borders, and borderRadius on text layers
added ability to conditionally render layers with the renderCondition property
added panel autoAdvance
added nextSequence property for sequences that appear out of order
added manuallySetImageIndex to allow forcing a layer's currentImage property via custom functions

you can now use strings for sequence ids instead of trying to track sequence indexes
changed main menu behavior:
- When chapters are disabled and the game is over show “New Game” instead of “Start Over”
- Don’t show the start over alert in this circumstance (because there’s no way to return to your current game without the chapter menu anyway)
you can now specify a separate advanceControlPositions for each step in an advanceControlSequence

fixed an issue where very large text layers were getting clipped
fixed an issue where pressing 0 to unlock all sequences didn't always work with nonlinear comics
fixed memory leak where panel audio was not being disposed of
fixed text opacity settings for manually rendered layers
advanceControlSequence now works for the final panel in a sequence
