Playground improvements: - simulate multiple creatures - delete and clone individual creatures - enable/disable energy consumption (creatures can die when they run out of energy; feed them to keep them alive) - enable/disable neural network window Evolution improvements: - option for only-brain mutations (to preserve body design in evolution) - separate water level setting for Evolution and Playground Other improvements: - more complete help messages everywhere - layout improvements, smaller buttons when run on iPad or MacOS

• Colors of sticks of f9 creatures now correspond to f9 genotype letters, making it easier to associate genes with their body counterparts • Slightly changed the way center of gravity and ground reaction forces are calculated, in order to make the simulation more consistent. This can influence the performance of your previously saved creatures • Improved the crossover operator for f9 genotypes • The app should now run more smoothly and reliably on Macs with Apple Silicon

Thank you for telling us that the application is buggy. Yes, it was a shame, but should be much better now. No more crashing during evolution!

• Includes the most recent Framsticks simulator version 5.0rc30, containing improved genetic operators, increasing the chance of evolving more colorful creatures (and many creatures from the legacy framsticks theater shows have been manually colorized) • Better graphics: more watery-looking water, improved creatures appearance • Bugs fixed: crash on pasting text from other apps, broken sharing window layout, blank custom fitness function editor, failing to open *.gen files in some circumstances

Genetics: • Genetic operator probabilities for "f1" and "f0" encodings are now optimised to get better results in shorter time • The exact operation (but not the general idea) of many "f1" modifiers was changed to allow for better coverage of the full parameter range. This can impair some of the previously designed or evolved creatures but should improve your future results • Improved "f1" mutation operator • Improved "f4" genetic encoding Evolution screen: • There is now a switch to prevent the screen from turning off during the evolution VR mode: • Prevent the screen from turning off automatically as long as the phone is in motion (makes a difference when you only use VR as a viewer without any input) • Brighten the screen when using your phone in VR goggles (normally the light sensor would unnecessarily dim the screen)
