Doodle 0.8.2 Released (https://github.com/nacular/doodle/releases/tag/v0.8.2) New Cassowary based Constraint Layout This release includes a new layout engine that will soon replace the current constraint based layout. This new implementation is based on the well known Cassowary algorithm and is therefore much more expressive and capable. The new implementation has a very similar API to the current one, so migration is less difficult. But there are key differences that mean current constraints won't always translate exactly. The new API is located in the

io.nacular.doodle.layout.constraints

package. Form Controls • New

singleChoiceList

for choosing a single item like

radioList

offers • New

optionalSingleChoiceList

for choosing zero or one item like

optionalRadioList

offers Better render performance
