FIRMWARE UPDATE VERSION 1.2 for SHENZHEN I/O is now live! NEW CONTENT

• The LX900C has been superseded by the LX910C, which includes a segment-based touchscreen interface and the ability to query whether a specific segment is on or off.
• The 100P-33 and 200P-33 memory chips are now available in the sandbox.
• Added a datasheet page for the N4PB-8000, LX700, and LX910C, which were previously undocumented.

• Added a new scoring metric for the number of lines of code used in a design.
• Added support for code breakpoints. To set one, control-click on a line of code (command-click on Mac).

• The LX700 numeric LCD available in the sandbox is now horizontal, not vertical, and has pins on both sides.
• The N4GP-1000 has been superseded by the N4PB-8000, which has a more neutral keybinding and takes up less board space.
• The soft lock on the 100P-14 is now removed with the 200P-14, instead of in the subsequent set of soft unlocks.
• The LC70Gxx family of logic chips no longer clamp input values to 0 or 100, and instead have unique "arithmetic functions" over the full range of input values. The datasheet has been updated to describe this new behavior.
• The number of test runs has been increased from 8 to 80.
• The power usage score reported in histograms and leaderboards is now the worst of all test runs.
• Improved the test cases for a few puzzles.
• Improved the display of signal indicators for input terminals.

• A simulation timeslice will no longer end before all simple I/O signals have stabilized.
• The simulation now executes code for microcontrollers in a deterministically random order.
• When running at resolutions below 1920x1080, the simulation now pauses before errors scroll off-screen to the left.
• Fixed a bug that allowed invisible characters to be entered into code editors, causing mysterious errors.
• Fixed a bug where breakpoint would not trigger during the first timeslice of a test run.
• Fixed a bug with inconsistent line endings in save files generated on non-Windows platforms.
• Fixed a bug that sometimes caused auto-format to not activate.
• Fixed a crash involving custom screens with too many segments.

• 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.
