FIRMWARE UPDATE VERSION 1.1 for SHENZHEN I/O is now live! NEW CONTENT

• Added the FM/iX "FM BLASTER", an FM-based synthesizer with one voice and ten instruments, available in the sandbox.
• Added a ¥0 "note" part that can be placed anywhere in a design to write additional documentation.

• Pin names are now shown for all pins when tab (show traces) is held.
• Added Steam achievements to the game related to solitaire and the secret puzzle.
• Improved the appearance of histograms, especially low-value production cost histograms.
• Added keyboard shortcuts for the playback controls: space is bound to simulate and pause, E is bound to step, D is bound to advance, and escape is bound to reset.
• The current code line indicator now fades slightly when that microcontroller is sleeping.
• In custom LCD screens, a very light gray color can now be used to connect two segments together without the line gray showing up as an actual segment.

• Most parts are now unlocked at the start of the game but "soft-locked" to discourage inexperienced players from using them prematurely and getting stuck.
• Changed the behavior of the dst instruction when one or both operands (acc and the new digit) are negative. The new behavior is symmetric with dgt, setting a digit and the sign of the accumulator separately as specified by the "new digit" operand.
• Modified the "pocket I Ching oracle" puzzle to provide more room for player designs.
• Modified the test cases for the "aquaponics maintenence robot", "spoiler blocking headphones", "personal sandwich assembler", and "precision food scale" puzzles.
• Changed the order of a few mid-game puzzles based on feedback about their difficulty.
• Added a visualization for input to a certain puzzle that needed it.

• It is now an error to define the same label twice in a single microcontroller.
• It is no longer an error to block without sleeping in the sandbox.
• Music is no longer played while a design in the prototyping area is running. Go make your own!
• Fixed a bug where histograms wouldn't update when returning to the conceptMAIL or conceptCAD menus.

• Build circuits using a variety of components from different manufacturers, like microcontrollers, memory, logic gates, and LCD screens.
  
• Write code in a compact and powerful assembly language where every instruction can be conditionally executed.
  
• Read the included manual, which includes over 30 pages of original datasheets, reference guides, and technical diagrams.
  
• Get to know the colorful cast of characters at your new employer, 深圳龙腾科技有限公司 (Shenzhen Longteng Electronics Co., Ltd.), located in the electronics capital of the world.
  
• Get creative! Design and test your own games and devices in the sandbox.
  
• Engineering is hard! Take a break and play a brand-new twist on solitaire.
