问题 the xml element "enabled" for a checkbox is deprecated. Eclipse tells me to use state_enabled instead. I tried to add android:state_enabled="false" to my checkbox within my xml instead of android:enabled="false" But it doesn't show any effect. The latter one does the desired.

问题 Deprecated in iOS 10.0: os_log(3) has replaced asl(3) So iOS 10.0 apparently deprecates the asl (Apple System Log) api and replaces it with the very limited os_log api. I use something similar to the code snippet below to read out log writes for the running app to show in a uitextview in app - and now it is full of deprecation warnings.

问题 According to MDN, we should most definitely not be using the .keyCode property. It is deprecated: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode On W3 school, this fact is played down and there is only a side note saying that .keyCode is provided for compatibility only and that the latest version of the DOM Events Specification recommend using the .key property instead.
