Decker 1.45 is a maintenance release with enhancements to Lil, interpreter performance, and usability of drawing tools.

New Features:

• The "Grid Size..." menu option is now "Grid and Scale...". The revised dialog makes it possible to configure the zoom level used in FatBits mode, providing additional flexibility for working on pixel art.

• Lil offers a new primitive operator, "window", which is used for breaking strings or lists into exclusive or sliding windows:

• Lil's @ operator is now significantly (about 2.5x) faster when the left argument is a primitive monadic (unary) operator. Like the improvements in v1.44, this expands the range of operations which can be performed in a "vectorized" fashion without requiring the Lil interpreter to execute loops at the bytecode level.
• The "pdf" module has been updated to v1.1, with simplifications to usage examples and better compatibility with third-party PDF readers.
• Decker now includes a new utility module, "bn", for performing arithmetic with arbitrary-precision natural numbers; handy if you feel like solving Project Euler problems or implementing a disturbingly large-scale Cookie-Clicker.

Decker Fantasy Camp 2024 is just a few days away. I can really use all the help I can get spreading the word- thanks in advance, folks!
