  • Fixed an issue where Player would not produce audio when phones were in silent mode
  • Fixed an issue where Map features would not show title and description information
  • Fixed an issue where setting the Canvas background to None would show a white background instead
  • Fixed an issue where floating point values without a leading zero were parsed as symbols instead of numbers
  • Fixed an issue where ImageSprites moved in a delayed fashion
  • Fixed an issue where the Slider component did not respect the minimum value
  • Added the ability to use localhost URLs in the WebViewer
  • Made the screen stay on while editing your project
  • Fixed an issue where a misspelling caused certain list blocks to not work correctly
  • Made the Button LongClick event fire after 500 ms rather than when the button is released
  • Added missing functionality related to parsing JSON and XML using dictionaries to the Web component
  • Fixed an issue where WebViewString is not set when a webpage initially loads
  • Implemented the missing join with separator and string reverse blocks
  • Fixed a bug where JavaScript prompts were not displayed
  • Fixed an issue where the YandexTranslate component would report a missing API key

Thank you for all of the reports of issues.

Ok, so we are still waiting for beta testing review. Hopefully it will be released to everyone soon.


Hi all, the beta version has been approved by Apple, so those of you in the beta testing program should be able to install this version now. The version is 2.60.1, build 2. If you have encountered any of the above issues in 2.60 and would like to help us with testing the next version, please use this link to join the TestFlight beta testing program.

Buenos dias

Muchas gracias de Antemano

The companion identified here is for iOS devices. If you don't have an iOS device, then I would recommend using the companion for Android instead.
