We will be releasing a new version of App Inventor tonight. This release is to address a few minor issues identified in the last major release. There is a new companion version 2.57b. You will not need to upgrade your companion unless you were affected by the dictionary key issue.
Fixes included in this release are:
- Fix an issue where "join"ed strings cannot be used to look up entries in dictionaries
- Fix an issue where projects including Sliders may not load
- Make visible the ThumbColorActive property in the blocks editor
