Decker v1.6 is a maintenance release with performance improvements, several bugfixes, and a new Lil feature.

Fixes (Native)

• Fixed a crash when using the "%a" format code with a specified length.

Fixes (Web and Native)

• Corrected mask corruption when flipping or rotating imported color images.
• Widget previews on the Cards dialog are now clipped to the dimensions of the card thumbnail.
• The read["sound"] function now correctly respects the 10 second limit for audio clips.
• When a deck is locked, the hidden menu bar will no longer interfere with dragging canvases.
• The j/k keyboard shortcuts for adjusting imported color image contrast are disabled in modal dialogs.
• Corrected binding strength of the Lil "-" operator to numeric literals in some situations.

New Features

• General performance improvements for native-Decker, providing as much as a 30% speedup while idling, as well as speedups for some canvas drawing operations.
• Introduced the "local" construct in Lil, to explicitly force the creation of a local variable. This does not increase expressiveness, but can make reorganizing code less error-prone in some situations, as well as making it easier to precisely decribe the behavior of Decker event handling with respect to how "magic variables" like card and widget references are bound. Note that the introduction of the new "local" keyword is a minor breaking change.
